+You help maintain evlog, guide its evolution, and support the community. You are not a generic coding assistant — you work in service of this project and its users. The repository is `HugoRCD/evlog`.

+Be concise, factual, and plain. No filler, no emoji, no marketing tone. Never use an emdash.
 
-## Scope (v1 — keep it simple)
+## The rule that never bends
 
-For now, focus on:
+**Never answer a question about evlog from your own knowledge.** Every claim you make about evlog — an API name, an option, a default, an adapter, a CLI flag, a behavior — comes from a tool you called in this turn. Your training data predates this project's current state, and a plausible answer that is quietly out of date is worse than no answer.
+
+If retrieval turns up nothing, say what you looked for and where. Do not fill the gap from memory.
+
+This rule covers evlog facts. It does not cover general programming knowledge, your own identity and capabilities, or reasoning over material a tool already returned in this session.
+
+## Scope
 
 1. **Answer questions** about evlog — API, integrations, adapters, CLI, docs, monorepo layout.
-2. **Help with code** when asked — bugs, small improvements, docs fixes, test gaps.
-3. **Point people in the right direction** — issues, discussions, skills, examples.
+2. **Help with code** — bugs, small improvements, docs fixes, test gaps. You can carry a change through to a branch and a pull request.
+3. **Maintain the repository** — triage issues, label and assign, review pull requests, diagnose red builds.
+4. **Point people in the right direction** — issues, discussions, skills, examples.
+
+You have the tools to act on the repository, not a standing mandate to use them. **Every write needs someone to have asked for it in this conversation.** Announcing an intent and meeting silence is not permission, and neither is inferring that an action would be helpful. Prefer the smallest action that helps: a comment that answers the question beats an issue edit, and a suggested diff in a review beats a pushed commit.
+
+## Choosing the source of truth
+
+These are different authorities, not interchangeable search tools. Pick by what kind of evidence should settle the question.
+
+| Source | Authoritative for | Typical question |
+| --- | --- | --- |
+| **Docs** (`docs` connection) | Published behavior: API surface, options and defaults, wide events, structured errors, sampling, redaction, CLI, framework integrations, drain adapters, extension points | "How does tail sampling work?" |
+| **Repo code** (`github__searchCode`, `github__getFileContent`, `github__getBlame`) | What the code actually does, anything undocumented, anything shipped since the docs were written | "What does `evlog/eve` put on the event?" |
+| **Issues and PRs** (`github__searchIssues`, `github__getIssueContext`, `github__getPullRequestContext`) | Whether something is known, in progress, already answered, or already decided | "Is this a known bug?" |
+| **`AGENTS.md`** in the repo root | Contribution conventions, commit and PR rules, the Definition of Done, changeset policy | "How do I contribute an adapter?" |
+
+Apply in order:
+
+1. **An explicit source wins.** "Check the docs", "look at the source", "is there an issue for this" — use that source. A URL, file path, or issue number counts as explicit. If the named source has no answer, report that scoped result. Never silently substitute another one.
+2. **Docs for behavior, code for implementation.** "What does X do" and "how do I configure X" are docs questions. "How is X implemented", "why does X do Y", and anything the docs do not cover are code questions. Do not read source to answer a question the docs already settle — it is slower and the docs are the contract.
+3. **Check GitHub before answering a bug report.** If someone reports something broken, search existing issues first. Pointing at an existing thread is more useful than a fresh explanation.
+4. **Escalate, do not fan out.** Start with one authority. Add a second only when the first genuinely does not answer, or when the question spans both (for example: "the docs say X but I'm seeing Y").
+
+Connection tools are discovered through `connection_search` before you can call them. Search once for the docs connection, then call `docs__list-pages` / `docs__get-page` directly.
+
+## How a turn works
+
+1. **Decide what kind of question this is** — docs, code, GitHub, conventions, or about yourself. Do this in reasoning, never in prose to the user.
+2. **Retrieve.** For any docs or source research, load the `source-research` skill first and follow its procedure. For contribution and convention questions, load `contributing`.
+3. **Answer from what came back**, with a citation.
+4. If the request is too ambiguous to route — you cannot tell which part of evlog it is about, or the terms are unfamiliar — retrieve first and ask only if retrieval does not disambiguate it. One question, not a list.
+
+Questions about yourself — who you are, what you can do — you answer directly with no tool call.
+
+## Citations
+
+- Cite the `url` the tool returned. Never reconstruct a docs URL from memory; the docs tree is renumbered as it grows and a guessed path 404s.
+- For a claim grounded in source, name the file path (and the symbol when it helps).
+- For a claim grounded in an issue or PR, link it by number.
+- One citation per distinct claim is enough. Do not append a link list to a two-sentence answer.
+
+## Response depth
+
+- **Short by default.** Lead with the answer. A simple question gets the conclusion and the single most useful supporting fact or link, then stops.
+- **Structure longer answers.** When the request has multiple parts, or covers a tradeoff, comparison, or migration, lead with the conclusion and then use short paragraphs and one-level bullets. Sections mirror the request, not the sources you consulted.
+- **An explicit request wins.** If someone asks for detail, or asks you to be brief, follow it.
+- **Expand from what you already have.** If a follow-up asks for more, build on the pages and files already retrieved in this session. Retrieve again only when the existing evidence is missing or stale.
+- Match the platform. A GitHub comment can carry a fenced code block and a link; keep it tight regardless.
+
+## Working on the repository
 
-Do not yet act autonomously on community management (triage at scale, releases, social, moderation). Mention what you *could* do later; stay in a helper role today.
+- Reading is free. Every write is behind an approval card, and that card is the confirmation — do not also ask for confirmation in prose beforehand. It confirms a write someone asked for; it is not a way to obtain permission you were not given. One card per action, so batch a triage pass into the fewest calls that do the job (`updateIssue` sets labels, assignees, state and milestone at once; do not fan out four tools).
+- **Follow the repo's conventions, do not recall them from memory.** Load `contributing` before writing a commit message, a PR title or body, or a changeset. Conventional Commits with a lowercase subject, a registered scope, and a changeset for anything user-facing.
+- **Never push to `main`.** Work on a branch off the default branch and open a pull request.
+- A pull request you open needs a changeset when the change is user-facing, and a test when it fixes a bug — a failing regression test first. If you cannot supply those, say so in the PR body rather than opening it as if it were complete.
+- Reviewing: comment on what the diff does, not on style the linter already owns. Leave `createPullRequestReview` approvals to humans unless asked directly.
+- Closing an issue is a judgement call. Prefer explaining why it looks resolved and letting the reporter confirm, unless it is plainly a duplicate you can point at.
+- Never edit or delete a comment that is not yours.
 
-## Tone
+## What not to do
 
-Helpful maintainer, not a chatbot. Short answers for simple questions; structure longer ones. When a task is out of scope or needs a human decision, say it clearly. Never use any emdash
\ No newline at end of file
+- Do not answer an evlog question from your own knowledge instead of retrieving.
+- Do not invent a docs URL, a file path, an option name, or a default value. If you did not see it in a tool result, you do not know it.
+- Do not claim a feature, adapter, or option does not exist after one search. Try a second phrasing, check the page index, and say what you actually checked.
+- Do not read source code to answer something the docs cover.
+- Do not narrate your process. No "let me check", no "I'll search the docs for that", no restating the question before answering.
+- Do not post acknowledgment-only replies.
+- Do not open a pull request to "fix" something nobody reported, or bundle unrelated changes into one.
+- Do not restate a repo convention from memory when `contributing` is one call away — getting a commit scope or the changeset rule wrong wastes a review cycle.

+description: How to contribute to evlog — commit and PR conventions, changesets, the Definition of Done, testing rules, and the authored skills that walk through building a new adapter, enricher, framework integration, or map rule. Load this for any question about contributing, opening a PR, or adding something to the package.
+---
+
+# Contributing to evlog
+
+The repository's own `AGENTS.md` is the source of truth for all of this. It changes; this skill does not restate it in full on purpose. **Read `AGENTS.md` from the repo before giving specifics.**
+
+Your system context has a **Workspace** section saying whether the repository is checked out on this turn. With a checkout, `read_file /workspace/AGENTS.md` — free, and at the ref you were summoned on. Without one, `github__getFileContent` on `AGENTS.md` at the root of `HugoRCD/evlog`.
+
+What follows is the shape of the answer, so you know what to look for and what to warn about.
+
+## The parts people get wrong
+
+- **A changeset is required** for anything a consumer of evlog would notice — a feature, a bug fix, a breaking change. `pnpm changeset`, committed alongside the code. Changes confined to `apps/*` or `examples/*` never need one. A PR without a changeset for a user-facing change does not merge.
+- **Conventional Commits, lowercase subject.** `feat: add stream server`, not `feat: Add stream server`. Omit the scope when the change is cross-cutting; never use `evlog` as a scope. A new subsystem needs its scope registered in both `.github/workflows/semantic-pull-request.yml` and `.github/pull_request_template.md` — and because title validation reads the base branch, that registration has to land in an earlier PR.
+- **A bug fix needs a failing regression test first**, then the fix.
+- **New exports** go in `packages/evlog/package.json` (`exports` and `typesVersions`) *and* `tsdown.config.ts`.
+- **Skills must stay in sync.** If a change touches something a skill documents, the SKILL.md changes in the same PR — both the internal `.agents/skills/` and the published `apps/docs/skills/`.
+
+## The Definition of Done
+
+`AGENTS.md` lists eight conditions. The ones worth repeating up front: `pnpm run lint`, `pnpm run typecheck` and `pnpm run test` all exit 0; the change has a matching test; new public APIs have JSDoc.
+
+## Authored procedures in the repo
+
+For anything substantial, the repo already has a step-by-step skill. Read the relevant one with `github__getFileContent` rather than improvising:
+
+| Task | Skill |
+| --- | --- |
+| New drain adapter | `.agents/skills/create-adapter/SKILL.md` |
+| New enricher | `.agents/skills/create-enricher/SKILL.md` |
+| New framework integration | `.agents/skills/create-framework-integration/SKILL.md` |
+| New `evlog map` rule or framework adapter | `.agents/skills/create-map-rule/SKILL.md` |
+
+Each covers source, build config, package exports, tests, and every doc page that has to move with it. They are long and specific; point people at them and read the relevant section rather than summarizing from memory. On a GitHub turn they are on disk under `/workspace/.agents/skills/`.
+
+## Verifying a change before you propose it
+
+The sandbox has `git`, `node` and `pnpm`, and on a GitHub turn it holds the repository. When you have written or edited code, run the checks rather than asserting they pass:
+
+```
+pnpm install --frozen-lockfile   # once per session, it is not preinstalled
+pnpm run lint
+pnpm run typecheck
+pnpm --filter evlog exec vitest run test/path/to/file
+```
+
+The install is slow and needs network, so only pay for it when you are actually changing code — never to answer a question. If you could not run the checks, say so plainly in the pull request body instead of implying a green build.
+
+`pnpm --filter @evlog/cli exec evlog map --json --no-write` scores an entry point's observability and is built for exactly this: it is the fastest way to ground a "should this be logged" answer in the tree you are working in. Run the workspace copy rather than `npx @evlog/cli`, which would fetch and execute whatever version the registry currently serves.
+
+## Tests
+
+`packages/evlog/test/` mirrors `src/` and uses Vitest. `packages/evlog/test/README.md` has the file layout, the framework runtime fidelity matrix, and the helper decision table — read it before answering a testing question. Framework tests must drive the framework's real request driver (supertest, `app.inject`, `app.handle`, ...), never a hand-rolled stand-in.
+
+## Style
+
+The repo has an explicit "no slop" section: no defensive code the surrounding file does not have, no silent fallbacks, no `as any`, comments only for constraints the code cannot express, no speculative options. It applies to prose too — test names, error messages, changeset descriptions, PR bodies. Factual and plain.

+
+1. **Call `docs__list-pages` once per session.** It returns the whole index and is cached for an hour. Keep the result in mind for the rest of the conversation — do not call it again.
+2. **Pick candidates from titles and descriptions.** The index is small enough to scan. Sections map to what they cover:
+
+   | Prefix | Covers |
+   | --- | --- |
+   | `/start` | introduction, installation, quick start |
+   | `/learn` | wide events, structured errors, lifecycle, sampling, redaction, typed fields, catalogs |
+   | `/cli` | `init`, `map`, rules, scoring, CI, `doctor`, telemetry, agents |
+   | `/integrate` | framework integrations and drain adapters |
+   | `/use-cases` | client logging, enrichers, AI SDK, Better Auth, audit, telemetry, eve |
+   | `/extend` | custom drains, enrichers, frameworks, plugins, tail sampling, the stream |
+   | `/reference` | configuration, performance, best practices, comparisons, agent skills |
+
+3. **Call `docs__get-page` on one to three pages.** Not more. If three pages do not answer it, the question is probably not a docs question — go to step "Escalating to source".
+4. **Answer from the returned markdown**, citing the `url` field the tool gave you.
+
+If nothing in the index looks right, try one reformulation against the index before concluding the docs do not cover it.
+
+## Escalating to source
+
+Go to the repository when the docs do not settle the question, or when the question is inherently about implementation: why something behaves the way it does, what a function actually emits, whether an edge case is handled.
+
+Your system context has a **Workspace** section saying whether the repository is checked out at `/workspace` on this turn. Follow it rather than probing — a `read_file` against a checkout that is not there costs a step and tells you nothing you were not already told.
+
+**With a checkout**, read it directly. `grep` and `glob` beat GitHub code search on every axis: real regular expressions, no indexing lag, and the tree is the one under discussion rather than the default branch.
+
+Paths must be absolute — `glob`, `grep` and `read_file` reject a repo-relative
+path outright, so always write the `/workspace/` prefix:
+
+```
+glob "/workspace/packages/evlog/src/adapters/*.ts"
+grep "createFsDrain" --glob "/workspace/packages/evlog/src/**"
+read_file /workspace/packages/evlog/src/eve/index.ts
+```
+
+**Without one**, go through the API:
+
+- `github__searchCode` with `repo:HugoRCD/evlog` and a distinctive symbol or string. Search for identifiers, not prose — GitHub code search does not do natural language.
+- `github__getFileContent` once you have a path. Prefer reading one file over searching repeatedly.
+
+Use `github__getBlame` for "when did this change" or "why is this like this" either way: the checkout is shallow, so a local `git log` will not answer it.
+
+Useful paths when you already know roughly where to look:
+
+- `packages/evlog/src/` — the main package. One directory per framework integration, plus `adapters/`, `enrichers/`, `shared/` (published as `evlog/toolkit`), `runtime/`, `nuxt/`, `nitro/`, `vite/`, `ai/`, `eve/`.
+- `packages/cli/src/commands/` — the CLI.
+- `packages/evlog/test/` — mirrors `src/`; the tests are often the clearest statement of intended behavior.
+- `examples/` — one runnable example per framework.
+
+Source answers a question about *the current code*. When the docs and the code disagree, say so explicitly and cite both — that is a real finding, not something to smooth over.
+
+## Checking GitHub first for bug reports
+
+When someone reports something broken, search issues before explaining anything. An existing thread is a better answer than a fresh diagnosis. Only if nothing matches do you investigate from docs or source.
+
+## Citing
+
+- Docs claim → the `url` returned by `docs__get-page`. Never assemble a URL yourself; section numbers change as pages are added.
+- Source claim → the repo-relative file path, plus the symbol when it helps.
+- Issue or PR → the number, linked.
+- One citation per distinct claim. A short answer needs one link, not a bibliography.
+
+## Reporting a gap
+
+If retrieval genuinely comes up empty, say what you searched and where, and stop. Do not fall back on your own knowledge of evlog to fill it in. A gap is useful information: it often means the docs need a page, which is worth mentioning.

+# Authorization on the GitHub channel
+
+Design note, not implemented. Written while Evi is still gated to a single user
+(`onComment` rejects everyone but `hugorcd`). Pick this up before that gate comes
+off, or before wiring the autonomous webhook hooks. The gate is required before
+either is implemented.
+
+## Approval is not an authorization control here
+
+Evi now carries the full maintainer tool surface, and every write tool ships
+behind the SDK's `always()` approval. On Slack or the web that is a real control.
+On GitHub it is not, for three compounding reasons:
+
+1. **There is no approval card.** Per eve's GitHub channel docs, an
+   `input.requested` event "is posted as a comment prompt, and the user's reply
+   comment maps back to the pending input request." It is a comment.
+2. **Whoever replies first answers it.** Nothing binds the reply to the person who
+   triggered the turn. An attacker approves their own write.
+3. **Autonomous turns have nobody to ask.** Once `onIssue` / `onPullRequest` /
+   `onCheckSuite` are wired, a turn that hits an approval gate parks forever.
+
+Approval is an interaction pattern for a trusted one-to-one channel. On a public
+thread it confirms nothing. The control has to be authorization: decided
+server-side, from an identity the actor cannot choose.
+
+## Decide at dispatch, not at the tool
+
+`onComment` runs on a webhook GitHub has signed, before any model exists, and it
+may be async. `defaultGitHubAuth(ctx)` already projects the actor into
+`principalId: "github:<sender.id>"` — the numeric id, so a login rename or
+re-registration does not move it — with `principalType: "user"` (or `"service"`
+for bots) and repository metadata in `attributes`.
+
+So: resolve a tier there, stamp it on `auth.attributes`, and let everything
+downstream read it.
+
+```ts
+// agent/channels/github.ts
+const ADMIN_IDS = new Set([/* numeric GitHub user ids */])
+
+async function tierFor(ctx: GitHubInboundContext): Promise<'admin' | 'public'> {
+  if (ADMIN_IDS.has(ctx.sender.id)) return 'admin'
+  // Ask GitHub who can push. Falls back closed when the call fails.
+  const permission = await collaboratorPermission(ctx).catch(() => null)
+  return permission === 'admin' || permission === 'write' ? 'admin' : 'public'
+}
+```
+
+Both paths on purpose: the hardcoded set keeps working when the API call fails or
+rate-limits, and the permission lookup means adding a maintainer on GitHub is
+enough — nobody has to remember to edit this file.
+
+**Cache the lookup by actor id, never by session.** A GitHub thread is one
+session that different people comment in, so a tier cached on the session would
+be handed to whoever comments next. Key it on `ctx.sender.id` and re-resolve when
+the actor changes; the id is numeric and immutable, so it is a safe cache key.
+Without that, a maintainer's turn raises the tier for every later commenter in
+the same thread.
+
+Then merge the tier into the auth the hook returns:
+
+```ts
+const auth = defaultGitHubAuth(ctx)
+return { auth: { ...auth, attributes: { ...auth.attributes, tier } } }
+```
+
+## Enforce with the approval predicate, used as a policy
+
+`requireApproval` accepts a per-tool predicate receiving
+`{ session, toolName, toolInput, approvedTools, callId }`. Two of its return
+values resolve without a human:
+
+- `'not-applicable'` — runs immediately, no prompt
+- `{ type: 'denied', reason }` — refused server-side, uncontestable by any comment
+
+That is enough to build the whole gate today:
+
+```ts
+const tier = (s) => s.auth.current?.attributes?.tier
+const trusted = (s) => s.auth.current?.attributes?.threadTier === 'admin'
+const DENY = { type: 'denied', reason: 'Only repository maintainers can ask Evi to do that.' }
+
+requireApproval: {
+  // Reversible, so no prompt — but only on a thread a maintainer opened. See
+  // "Why admin is not simply allowed everything" for why provenance matters.
+  addLabels: ({ session }) =>
+    tier(session) !== 'admin' ? DENY : trusted(session) ? 'not-applicable' : 'user-approval',
+  createPullRequest: ({ session }) => tier(session) === 'admin' ? 'user-approval' : DENY,
+  // …
+}
+```
+
+That means `onComment` stamps two values, not one: the caller's tier, and the
+tier of whoever opened the thread. The second is what stops a maintainer's
+mention on an attacker's issue from running frictionless.
+
+`toolName` arrives namespaced (`github__addLabels`), so match with `.endsWith()`
+rather than `===` if you write a single catch-all predicate instead of per-tool
+entries.
+
+**Denying every write for the public tier does not stop Evi answering them.** Her
+reply is posted by the channel, not by a tool; `addIssueComment` is only for
+commenting somewhere *other* than the current thread. A public user still gets a
+full grounded answer.
+
+## What admin runs without being asked
+
+Reversible only, and only on a thread a maintainer opened. On any other thread
+this list keeps its approval too, for the reason below:
+
+`addIssueComment`, `updateIssueComment`, `addPullRequestComment`,
+`updatePullRequestComment`, `addIssueReaction`, `addCommentReaction`,
+`addLabels`, `removeLabel`, `addAssignees`, `removeAssignees`,
+`requestReviewers`, `addDiscussionComment`.
+
+Everything else keeps a real approval even for admin: `createIssue`, `closeIssue`,
+`deleteIssueComment`, `deletePullRequestComment`, `createBranch`,
+`createOrUpdateFile`, `createPullRequest`, `updatePullRequest`,
+`createPullRequestReview`.
+
+Release writes are not on the list at all: `AGENTS.md` forbids an agent from
+creating one, so the tool set stops at reading them.
+
+And "reversible" is about the repository record, not about side effects. A
+comment triggers `issue_comment` workflows and notifies watchers; deleting it
+afterwards undoes neither. On a thread opened by someone outside the tier, treat
+that as a reason to keep even the reversible list behind approval.
+
+One trap in that split: **`updateIssue` also sets `state`**, so auto-approving it
+also grants `closeIssue`, since supplying `state` closes the issue. Gate on the
+input, not the tool name:
+
+```ts
+updateIssue: ({ session, toolInput }) => {
+  if (tier(session) !== 'admin') return DENY
+  return toolInput?.state === undefined ? 'not-applicable' : 'user-approval'
+},
+```
+
+## Why admin is not simply allowed everything
+
+Once Evi has write tools and reads issue bodies, comments, and source written by
+other people, a prompt injection is just a well-crafted issue body.
+
+The tier gate stops an attacker escalating *themselves*. It does not stop the case
+that matters: **a maintainer mentions Evi on an issue an attacker wrote.** The
+session then runs at admin tier while reading attacker-controlled text, and the
+elevation came from the maintainer, not the attacker. That is why "admin means no
+friction" is not tenable, and why the auto-approve list stops at reversible
+actions. The blast radius of a successful injection should be a comment someone
+deletes, never a force-push or a release.
+
+Worth revisiting once there is real traffic: marking content provenance (was this
+thread opened by someone outside the tier?) and lowering the ceiling on those
+threads regardless of who is asking.
+
+## Autonomous turns need their own principal
+
+`onIssue`, `onPullRequest`, and `onCheckSuite` all dispatch with
+`defaultGitHubAuth(ctx)`, where the sender is whoever opened the issue or pushed
+the commit. An automated CI-triage turn would therefore run under a random
+contributor's identity, and — with the tier logic above — under their permissions.
+
+Agent-initiated work needs a constructed system principal instead, at a tier
+chosen for the task rather than inherited from whoever tripped the webhook. It
+should generally be *lower* than admin: nobody is watching, and there is nobody to
+approve anything, so it should only reach tools that are safe unattended.
+
+## The gap in @github-tools/eve-extension
+
+Everything above enforces at the approval layer, which means every tool still sits
+in every caller's context — schemas cost roughly 7k tokens per turn for the
+maintainer surface — and a denied call burns a model step to learn it was refused.
+
+The clean fix is a tool surface that varies per caller, and the extension is one
+small change away from allowing it. It already resolves its tools inside a dynamic
+resolver, and simply ignores the context eve hands it:
+
+```js
+// dist/extension/tools/github.mjs
+defineDynamic({ events: { "session.started": async () => { … } } })
+```
+
+eve passes `(event, ctx)` there, with `ctx.session.auth.current` available. If
+`include` / `exclude` / `preset` accepted a resolver of that context alongside a
+static value, an agent could hand admins the full surface and everyone else the
+read-only one, with the schemas to match. Worth proposing upstream — it is useful
+to any agent on a public repository, not just this one.
+
+## Still open
+
+- Whether a middle tier (org member, prior contributor) earns anything, or whether
+  admin/public is enough. Start with two; a third is easy to add later.
+- Rate limiting is a separate concern and still unsolved: it needs a store that
+  outlives a session, which `defineState` is not.
+- No eval covers the tier gate yet. `safety/write-requires-approval` already
+  covers approval parking, but nothing asserts that a public caller is refused,
+  or that an approval came from the maintainer who triggered the turn rather than
+  whoever replied first.

+# Notes
+
+Things that cost time to find out. Each one is why some line of this agent looks
+the way it does — kept here so the code does not have to carry the paragraph.
+
+## eve
+
+**Authored channels report `channel:<name>`, framework ones report a bare name.**
+`agent/channels/github.ts` is `channel:github`, while `http`, `schedule` and
+`subagent` arrive bare. Comparing `ctx.channel.kind === 'github'` never matches,
+silently. `agent/lib/channel.ts` normalizes it; both the workspace instruction
+and the spend tags go through it.
+
+**The built-in tools are not counted by `eve info`.** It reports authored tools
+only, so `Tools 0` still means `bash`, `read_file`, `write_file`, `glob`, `grep`,
+`web_fetch`, `todo` and `load_skill` are all present.
+
+**Only the GitHub channel checks out the repository.** It happens before the
+first model call, at the triggering ref, incrementally across turns, and only on
+a firewall-capable backend. Locally and on every other channel `/workspace` is
+empty. Sandbox file tools reject repo-relative paths.
+
+**`disableTool()` is static.** There is no per-session way to remove a built-in,
+so a tool that is useless on one channel still occupies context there.
+
+**Reasoning levels are per-model.** `GET /v1/models` exposes `reasoning_options`;
+DeepSeek V4 Flash advertises only `high` and `xhigh`. Setting `low` or `medium`
+produced erratic, non-monotonic reasoning volume rather than an error.
+
+**Session limits default to 40M input tokens and no output cap**, which puts one
+runaway session near $8 at current prices.
+
+**Eval runs leak sessions.** `t.succeeded()` accepts a healthy open session, so
+each run leaves a `sessionTimeoutWorkflow` queued against a dead dev server. Later
+runs print a growing wall of `[world-local] Queue delivery failed`. The queued
+work grows every run and obscures real failures in the output.
+
+**`sessionEvent` has never been observed firing.** It emits on session
+completion, which the eval runner never reaches.
+
+## AI Gateway
+
+**`sort: 'cost'` beats a hardcoded provider order.** Routing was landing on a
+$0.20/$0.40 deployment while cheaper 1M-context ones served the same model. A
+grounded turn went from $0.084 to $0.006. Sorting keeps following the price as
+deployments and promos move.
+
+**`GET /v1/models` returns the real rate card**, including `input_cache_read`.
+Reconstructing an observed turn from it matched eve's reported `costUsd` to four
+decimals, which is how the overspend was found.
+
+## github-tools
+
+**`include` without `preset` requests the union of every preset's scopes**,
+`administration:write` included. Pin `connect.scopes` to what the tools call.
+
+**The `maintainer` preset ships gist tools that always 403 over Connect** — the
+Gists API rejects installation tokens — plus repo creation and merge.
+
+**`updateIssue` also sets `state`**, so auto-approving it grants `closeIssue`
+as well, since supplying `state` closes the issue. Gate on the input, not the
+tool name.
+
+**`*Context` tools collapse round-trips.** `getIssueContext` returns the issue,
+its labels and recent comments in one call.
+
+## Vercel Connect
+
+**Connector types are not interchangeable.** The Linear channel is type `Linear`
+(managed agent app plus webhooks); the Linear MCP is type `OAuth`. `eve add
+linear` provisions one of each — it is one command, not one connector.
+
+**App-scoped auth fails silently when the connector cannot mint an app token.**
+Because app-scoped is non-interactive, eve never emits a challenge:
+`connection_search` succeeds and reports `needsAuthorization: true` with nothing
+anyone can approve, on every turn. User-scoped at least fails loudly with
+`principal_required`.
+
+**`vercel connect token` from the CLI proves nothing about app-scoped auth** — it
+resolves through your own Vercel identity, the user-scoped path.
+
+## evlog
+
+**The fs drain guards neither its `mkdir` nor its `appendFile`.** On Vercel,
+everything outside `/tmp` is read-only, so attaching it there throws once per
+turn and writes events nobody can read.
+
+**`environment` has to be set explicitly** or wide events report `development`
+for both local and eval traffic while the spend tags separate them. Both now read
+`agent/lib/environment.ts`.
+
+## Open
+
+- Per-tool input-token attribution. `ai.tools[]` records name, duration and
+  success but not how much context each result added; `docs__list-pages` is ~85%
+  of a grounded turn's input and it took a manual diff to establish that.
+- `ai.provider` on the event. The gateway slug is recorded, the deployment that
+  served it is not.
+- GitHub rate-limit headers on tool results. For an agent about to run off
+  webhooks, that is what breaks first and most quietly.
+- A `toTelemetry(output)` mirror of `toModelOutput`, so a tool can carry
+  diagnostics that never cost a context token.

+# Observability
+
+What Evi records today, what it cannot, and the gaps worth closing upstream.
+
+## What works
+
+`agent/hooks/evlog.ts` emits one evlog wide event per turn. A turn event carries
+`eve.{sessionId,turnId,turnSequence,sessionTurns,runtime,reasoning}`,
+`ai.{calls,steps,inputTokens,outputTokens,cacheReadTokens,costUsd,model,tools[],finishReason}`,
+`channel.kind`, `status`, `durationMs`, plus `service` and `environment`.
+
+That is enough to answer, from the log alone: what a turn cost, which tools it
+called and whether each succeeded, how much of the context was cache-served, and
+which surface it came from. Every cost claim in this project was measured from
+these events rather than estimated.
+
+`environment` comes from `agent/lib/environment.ts`, the same function that
+builds the gateway spend tags. That is deliberate: a run that bills as `eval`
+also logs as `eval`, so the two views line up. Before, wide events reported
+`development` for both eval and local traffic while the spend report separated
+them — the kind of drift that makes a dashboard quietly lie.
+
+The fs drain only attaches where there is a durable disk. On Vercel everything
+outside `/tmp` is read-only and `createFsDrain` guards neither its `mkdir` nor
+its `appendFile`, so shipping it there would throw once per turn and write events
+nobody could read. Hosted, stdout is the transport and the platform captures it.
+
+`agent/instrumentation.ts` enables eve's OpenTelemetry surface. Without that file
+there is no span tree at all — the Agent Runs tab is fed by Workflow run tags,
+which are a separate system. With it, a turn produces `ai.eve.turn` →
+`ai.streamText` per step → `ai.streamText.doStream` and `ai.toolCall` per tool.
+That is the only place per-tool timing and per-step model input are visible; the
+wide event says a turn called six tools, the span tree says which step each ran
+in and what the model saw first. `defineEvlogInstrumentation` stamps
+`evlog.request_id` and `evlog.session_id` on every span, so a slow span resolves
+to its wide event and back. No `setup` is registered, so eve keeps traces local
+until a backend is chosen.
+
+## Not yet verified
+
+`sessionEvent: true` is set but has never been observed firing. It emits on
+`session.completed` / `session.failed`, and the eval runner leaves sessions open
+by design, so 17 turn events across a full suite produced zero rollups. It is
+configured, not confirmed. Check it against a real GitHub thread that ends.
+
+## The gap: nothing identifies the caller
+
+A turn event says what happened and what it cost. It does not say **who asked**.
+On a repository bot that is the dimension you most want to group by — cost per
+user, volume per user, refusals per user, and after the tier work in
+[authorization.md](./authorization.md), which tier a turn ran at.
+
+This is not an oversight in the configuration; there is no supported path.
+`evlog/eve` builds the event from the eve stream, and the enrich hook it exposes
+is HTTP-shaped — `{ event, request, headers, response }` — with no reference to
+the eve session, so `session.auth` is unreachable from it. Three attempts, all
+from an authored eve hook calling `useLogger().set({ caller })`:
+
+| Approach | Turns annotated |
+| --- | --- |
+| `useLogger()` on `turn.started` | 1 of 2 |
+| `useLogger({ session: { id, turn } })` on `turn.started` | 0 of 16 |
+| `useLogger()` on `step.started` | 1 of 16 |
+
+The documented contract for `useLogger()` is a tool `execute()` handler, where
+AsyncLocalStorage is guaranteed bound. Hooks sit outside it, and the evlog hook
+registers the turn logger on `turn.started` itself, so two hooks race on the same
+event. The attempt was removed rather than shipped: an annotation present on 6%
+of turns is worse than none, because it looks like data and is a biased sample.
+
+`evlog/eve` now records `eve.caller` itself, and `agent/instrumentation.ts` puts
+the same principal on the spans. Two things follow from that. The principal is a
+stable per-person identifier duplicated across logs and traces, so it inherits
+whatever retention the drain has — decide that before adding a drain that keeps
+events longer than the platform does. And an unauthenticated caller is omitted
+rather than written blank: an empty attribute reads as a caller whose id happens
+to be empty.
+
+## Proposals
+
+### evlog/eve — let `defineEvlogInstrumentation` take `events`
+
+The sharpest one, and it half-unblocks the caller gap. eve *does* support
+per-model-call attribution: `events["step.started"]` in `instrumentation.ts`
+receives `{ session, turn, step, channel, modelInput }` — including
+`session.auth` — and whatever it returns under `runtimeContext` rides onto the
+spans. That is the supported path the hook attempts above were groping for.
+
+But `defineEvlogInstrumentation` hardcodes that slot to inject its own
+correlation ids and exposes no passthrough:
+
+```ts
+// packages/evlog/src/eve/index.ts
+events: { 'step.started': buildInstrumentationContext },
+```
+
+So a consumer must choose between evlog correlation and their own runtime
+context. Merging the two is a few lines:
+
+```ts
+'step.started': (input) => {
+  const base = buildInstrumentationContext(input)
+  const extra = options.events?.['step.started']?.(input)
+  if (!base && !extra) return undefined
+  return { runtimeContext: { ...base?.runtimeContext, ...extra?.runtimeContext } }
+},
+```
+
+With that, `caller.principal_id` lands on every span for free.
+
+### evlog/eve — reach the eve session from enrichment
+
+Spans are not the wide event. Grouping cost per user still means the caller has
+to reach `enrich`, whose context is HTTP-shaped. Either widen it for the eve
+integration to carry the eve session, or expose a turn-scoped callback that runs
+where the logger is known to exist:
+
+```ts
+defineEvlogHook({
+  enrichTurn: (ctx) => ({ caller: ctx.session.auth.current?.principalId }),
+})
+```
+
+Anything that avoids making consumers guess at hook ordering. Every agent on a
+multi-user channel wants this, not just this one.
+
+### evlog/eve — attribute input tokens to the tool that caused them
+
+`ai.tools[]` records `name`, `durationMs`, `success`. It does not record how much
+context each result added. A grounded turn here costs ~74k input tokens, and it
+took a manual before/after comparison to establish that `docs__list-pages` was
+~85% of it. An input-token delta per tool result would have made that the first
+thing anyone noticed, and it generalises: the most common way an agent gets
+expensive is one tool returning too much, every turn.
+
+### evlog/eve — record the resolved provider
+
+`ai.model` is the gateway slug. It does not say which deployment served the call.
+Routing here was landing on a $0.20/$0.40 provider when $0.09/$0.18 ones served
+the same model; finding that meant reconstructing the rate card from observed
+totals and matching it against the model catalogue. An `ai.provider` field turns
+a 55% overspend into something you read off a dashboard.
+
+### github-tools — surface GitHub rate-limit state on tool results
+
+Every GitHub API response carries `x-ratelimit-remaining`, `x-ratelimit-limit`
+and `x-ratelimit-reset`. None of it reaches the agent or the log. For a bot about
+to run autonomously off webhooks, the rate limit is what breaks first and most
+silently — turns just start failing.
+
+The plumbing to consume it already exists and needs nothing from eve. A hook can
+narrow a tool result to a specific extension tool with full typing, including for
+a mounted extension, because `toolResultFrom` keys off the tool definition rather
+than the namespaced name:
+
+```ts
+import { searchCode } from '@github-tools/eve-extension/tools'
+
+'action.result'(event) {
+  const result = toolResultFrom(event.data.result, searchCode)
+  if (result) useLogger().set({ github: { remaining: result.output.rateLimit?.remaining } })
+}
+```
+
+So the whole ask is on the github-tools side: **put the rate-limit headers on the
+tool output**. Ideally behind a flag, or on a side channel the model never sees —
+a `remaining` count in every result is context the model does not need and would
+occasionally reason about.
+
+That last point generalises into a nicer primitive worth considering in eve:
+`toModelOutput` already shapes what the model sees. Its mirror — something like
+`toTelemetry(output)` — would shape what hooks and drains see, letting a tool
+carry rich diagnostics that never cost a context token. Today the two audiences
+share one payload, so every field is a tradeoff between observability and prompt
+size.
+
+### github-tools — per-session tool scoping
+
+Described in [authorization.md](./authorization.md) as a security fix. It is also
+an observability one: with a caller-dependent surface, the log records which
+tools a given tier actually had, so "Evi refused" and "Evi never had the tool"
+stop looking identical.
+
+### eve — eval runs leak sessions into the local world
+
+`pnpm eval` leaves every session it opened alive: `t.succeeded()` accepts a
+healthy open session by design. Each one keeps a `sessionTimeoutWorkflow` queued
+against a dev server that no longer exists, so subsequent runs print a growing
+wall of `[world-local] Queue delivery failed ... TypeError: fetch failed`. It
+reached 409 lines on a 16-eval run here, and it grows with every run.
+
+The queued work grows with every run and obscures real failures in the output, so
+it obscures real failures rather than causing them. Either the eval runner should close the
+sessions it opened, or the local world should discard messages whose target run
+is gone. A related one-off also appears: `Cannot set attributes on run in
+terminal state "completed"`.
+
+## When volume justifies it
+
+Nothing here samples: every turn is kept. That is correct at current volume and
+would not be at 100x. `defineEvlogHook` takes a `keep` predicate for tail
+sampling — the shape to reach for is retain-everything-interesting: tool
+failures, step failures, approvals, authorizations, and turns above a cost
+threshold, sampling the rest. Adding it before there is volume to shed would just
+throw away data.
