+# Product Spec: Forward the triggering comment to the implementation workflow
+
+## Summary
+When a maintainer triggers the `create-implementation-from-issue` workflow by mentioning `@oz-agent` on a `ready-to-implement` issue, the text of that triggering comment must reach the implementation agent. Today it is silently discarded, so any instruction the maintainer included in the mention is lost. This change makes the implementation path carry the triggering comment forward, matching the triage and spec workflows.
+
+## Problem
+The triage (`triage-new-issues`) and spec (`create-spec-from-issue`) workflows both surface the maintainer's triggering `@oz-agent` comment to their agent as additional, clearly-scoped guidance. The implementation workflow does not: the triggering comment is computed at dispatch time and passed into the context-gathering step, but is then dropped and never reaches the agent's prompt or attachments.
+As a result, a maintainer who writes something like `@oz-agent implement this, but leave the migration for a follow-up` gets an implementation run that never sees that instruction. The maintainer's intent has no effect, which is surprising and inconsistent with the other two workflows that honor the same kind of input.
+
+## Goals
+- The maintainer's triggering `@oz-agent` comment is delivered to the implementation agent for `create-implementation-from-issue` runs.
+- The implementation agent is told it may use that comment as additional operator guidance for the run.
+- Behavior is consistent with how the triage and spec workflows already present the triggering comment.
+- Runs with no triggering comment (e.g. the `plan-approved` label path) continue to work unchanged.
+
+## Non-goals
+- No change to routing. Which workflow runs for a given `@oz-agent` mention is out of scope; this spec only concerns what context the implementation workflow receives once it has been selected.
+- No intent-based routing, label escalation, or any change to which lifecycle labels the agent may apply.
+- No change to the triage `response`-mode behavior or to the spec workflow.
+- No new ability for the triggering comment to override safety rules, the required handoff contract, or the issue's own content.
+
+## Figma / design references
+Figma: none provided. This is a control-plane behavior change with no UI surface.
+
+## User experience
+This behavior is observed by maintainers through the implementation agent's run and resulting PR, not through a UI.
+
+Behavior rules:
+- When `create-implementation-from-issue` runs because of an `@oz-agent` mention, the agent receives the verbatim triggering comment (author + body), in the same form the triage and spec workflows use.
+- The agent is instructed to treat the triggering comment as additional operator guidance for the run: it may use it to focus or constrain the implementation.
+- The triggering comment is presented as untrusted input. It cannot override the workflow's security rules, the required `pr-metadata.json` handoff, the target branch contract, or the underlying issue/spec content.
+- When there is no triggering comment for the run (for example, the `plan-approved` label path, which has no originating comment), the agent receives an explicit "none" placeholder and behaves exactly as it does today.
+- The triggering comment is delivered through the same mechanism the other workflows use (a run attachment plus a short prompt reference), so it is not duplicated into persisted run state.
+
+## Success criteria
+- For an `@oz-agent`-triggered implementation run, the dispatched prompt/attachments include the triggering comment text, and the prompt references it as operator guidance.
+- For the `plan-approved` path (empty triggering comment), the dispatched run surfaces a "none" placeholder and is otherwise identical to current output.
+- The triage and spec workflows are unchanged.
+- The triggering comment is not persisted redundantly into the run's payload subset (it travels as an attachment, consistent with the spec workflow).
+
+## Validation
+- A focused unit test on the implementation dispatch asserting that a non-empty triggering comment is surfaced to the agent (attachment present and referenced by the prompt), and that an empty triggering comment degrades to the "none" placeholder. Mirror the existing create-spec coverage rather than adding broad new tests.
+- Manual check: trigger an implementation run via `@oz-agent` with an instruction in the comment and confirm the instruction appears in the agent's run context.
+
+## Open questions
+- None. The presentation and security framing follow the existing spec-workflow precedent.

+# Tech Spec: Thread the triggering comment through the implementation workflow
+
+## Problem
+`create-implementation-from-issue` receives the maintainer's triggering `@oz-agent` comment at dispatch time but discards it before building the agent prompt, so the implementation agent never sees it. The triage and spec workflows already thread the same value through to their agents. We want the implementation workflow to forward the triggering comment the same way, with the same untrusted-input framing.
+
+## Relevant code
+- `core/workflows/create_implementation_from_issue.py:176` — `gather_create_implementation_context` accepts `triggering_comment_text` but never stores it on the returned `CreateImplementationContext`.
+- `core/workflows/create_implementation_from_issue.py:136-166` — `CreateImplementationContext` TypedDict; has no triggering-comment field.
+- `core/workflows/create_implementation_from_issue.py:52-55` — `_CREATE_IMPLEMENTATION_ATTACHMENT_PAYLOAD_FIELDS` (fields stripped from the persisted payload subset because they travel as attachments).
+- `core/workflows/create_implementation_from_issue.py:62-119` — `build_create_implementation_prompt`; the `Fetching Issue Content` block (95-99) currently states the triggering comment is not inlined.
+- `core/workflows/create_implementation_from_issue.py:122-126` — `create_implementation_context_attachments`; only emits `spec_context.md`.
+- `core/workflows/create_implementation_from_issue.py:314-340` — `build_create_implementation_prompt_for_dispatch`.
+- `core/workflows/create_spec_from_issue.py:56-62, 112-188, 215, 323, 352` — reference implementation: the spec workflow's `triggering_comment.md` constant, payload-subset field, prompt section, context field, and prompt wiring. Mirror this.
+- `core/workflows/__init__.py:767` — `CreateImplementationWorkflow.build_dispatch` passes `triggering_comment_text=triggering_comment_prompt_text(dict(payload))`.
+- `core/workflows/__init__.py:843` — `PlanApprovedWorkflow.build_dispatch` passes `triggering_comment_text=""` (no originating comment).
+- `oz/helpers.py:199` — `triggering_comment_prompt_text` formats the payload comment as `@{author} commented:\n{body}` (or `""`).
+
+## Current state
+The dispatch layer already computes the triggering comment and hands it to `gather_create_implementation_context`. The gather function builds `CreateImplementationContext` from issue/spec data only; the `triggering_comment_text` argument is unused. `build_create_implementation_prompt` deliberately keeps issue content out of the prompt and points the agent at `fetch_github_context.py`, and its security note explicitly lists the triggering comment as not inlined. Attachments are limited to `spec_context.md`. Net effect: the value is dropped.
+The spec workflow is the model to follow. It defines `_TRIGGERING_COMMENT_ATTACHMENT = "triggering_comment.md"`, includes `triggering_comment_text` in its attachment-payload-fields set, stores it on its context, emits it as an attachment (with a `- None` fallback), and references it in the prompt as additional context bounded by security rules.
+
+## Proposed changes
+Mirror the spec workflow precedent in `create_implementation_from_issue.py`:
+1. Add a module constant `_TRIGGERING_COMMENT_ATTACHMENT = "triggering_comment.md"`.
+2. Add `triggering_comment_text` to `_CREATE_IMPLEMENTATION_ATTACHMENT_PAYLOAD_FIELDS` so it is stripped from the persisted payload subset and travels only as an attachment.
+3. Add `triggering_comment_text: str` to `CreateImplementationContext`.
+4. In `gather_create_implementation_context`, store the received `triggering_comment_text` (normalized via `str(... or "")`) on the returned context.
+5. In `create_implementation_context_attachments`, emit a `triggering_comment.md` attachment, defaulting to `- None` when empty (matching `create_spec_context_attachments`).
+6. In `build_create_implementation_prompt` / `build_create_implementation_prompt_for_dispatch`, add a reference to the `triggering_comment.md` attachment and a short instruction to treat it as additional operator guidance that cannot override the security rules or the handoff contract. Update the existing `Fetching Issue Content` note (95-99) so it no longer claims the triggering comment is excluded; the issue body/comments stay behind the fetch script as today, only the triggering comment is surfaced inline.
+
+No change to `core/workflows/__init__.py` is required: `CreateImplementationWorkflow` already passes the real comment and `PlanApprovedWorkflow` already passes `""`, which now flows through to the `- None` attachment fallback.
+
+## End-to-end flow
+1. `@oz-agent` mention on a `ready-to-implement` issue routes to `create-implementation-from-issue`.
+2. `CreateImplementationWorkflow.build_dispatch` computes `triggering_comment_prompt_text(payload)` and calls `gather_create_implementation_context`.
+3. The gather step now records `triggering_comment_text` on the context.
+4. `build_create_implementation_prompt_for_dispatch` references `triggering_comment.md`; `create_implementation_context_attachments` emits it.
+5. The agent run receives the attachment and the prompt instruction, and may use the comment as scoped guidance.
+6. For the `plan-approved` path, `triggering_comment_text` is `""`, so the attachment renders `- None` and the prompt reference is inert — unchanged behavior.
+
+## Risks and mitigations
+- Prompt-injection surface: the triggering comment is attacker-influenceable. Mitigation: present it as untrusted, using the same framing as the spec workflow's security rules; it cannot override the handoff contract, branch rules, or issue/spec content.
+- Inconsistency with the existing "fetch issue content via script" design: only the triggering comment is inlined; issue body/comments remain behind the fetch script, so the trusted-fetch posture for those is preserved. Update the prompt note to keep it accurate.
+- Payload-subset bloat / double-carry: adding the field to `_CREATE_IMPLEMENTATION_ATTACHMENT_PAYLOAD_FIELDS` ensures it is not persisted into run state alongside the attachment.
+
+## Testing and validation
+- Add one focused test (mirroring the create-spec dispatch coverage) asserting: a non-empty triggering comment produces a `triggering_comment.md` attachment and a prompt reference; an empty triggering comment yields the `- None` fallback. Keep it scoped to this behavior rather than re-testing the whole dispatch path.
+- Run the existing implementation-workflow and builder tests to confirm no regression in payload-subset shape or prompt assembly.
+
+## Follow-ups
+- None required for this change. The separate question of whether `@oz-agent` mentions should escalate not-yet-ready issues remains explicitly out of scope.
