 ### Tracker Conventions
 
-- The roadmap project is the source of truth for prioritization.
+- The roadmap project is the source of truth for prioritization and claim status — use it, not labels.
 - Issues in the roadmap are prioritized; issues outside it are not.
 - `bug` marks defects.
 - Issues without `bug` are non-bug work by default.
-- `in-progress` marks an issue as claimed by an agent — do not start work on it.
 - `core`, `wui`, and `tui` are area labels.
 - Keep issue bodies focused on the handoff contract: objective, design latitude, acceptance signals, non-goals, and related links.
 - Do not put priority metadata in issue bodies.

+# Plan: hooks.pre_run — pre-eval environment injection
+
+Issue: #1149
+
+## Problem
+
+Users who fetch secrets at runtime (e.g. from Azure Key Vault, AWS Secrets Manager) must wrap the
+`agentv` CLI in a project-level script. A generic `hooks.pre_run` config option removes this need.
+
+## Implementation
+
+### Files changed
+
+| File | Change |
+|------|--------|
+| `packages/core/src/evaluation/hooks.ts` | New — `parseEnvOutput()` and `runPreRunHook()` |
+| `packages/core/src/evaluation/config.ts` | Add `hooks.preRun` to Zod schema + TS type |
+| `packages/core/src/evaluation/loaders/config-loader.ts` | Add `HooksConfig` type + `parseHooksConfig()` + wire into `loadConfig()` |
+| `packages/core/src/index.ts` | Export `runPreRunHook`, `parseEnvOutput` |
+| `apps/cli/src/commands/eval/run-eval.ts` | Import `runPreRunHook`; call before `normalizeOptions` |
+| `plugins/agentv-dev/skills/agentv-eval-writer/references/config-schema.json` | Add `hooks.pre_run` to JSON schema |
+| `packages/core/test/evaluation/hooks.test.ts` | New — unit tests for `parseEnvOutput` |
+
+### Precedence
+
+YAML config (`hooks.pre_run`) takes precedence over TS config (`hooks.preRun`). This matches the
+existing pattern for other settings.
+
+### Env var injection rules
+
+- Parses `export KEY="value"` (shell export) and `KEY=value` (dotenv) from stdout
+- Existing env vars are NOT overwritten — process.env always wins
+- Non-zero exit throws, aborting the eval
+- Stderr forwarded to process.stderr so users see hook output
+
+## Docs to update before merge
+
+- `apps/web/src/content/docs/` — add `hooks.pre_run` to the config reference page
+- Delete this plan file

+ * ## Supported output formats
+ *

+ *   export KEY="value"   (shell export — quotes optional)
+ *   KEY=value            (dotenv — no export prefix)
