 ### House of Agents (retired)
 The houseofagents multi-agent runtime was retired in favor of **workflow runs** (`nerve/workflows/`, the `workflow_run_*` tools) — budget-capped multi-agent runs with journals, live spend tracking, and run-scoped kill. See [workflow-runs.md](workflow-runs.md). The `hoa_*` tool names remain registered as deprecation stubs (gated by `houseofagents.enabled`) that point callers at `workflow_run_start`.

 Both skill jobs use `source="skill-extractor"` or `source="skill-reviser"` on created tasks. When their plans are approved, the plan approval handler creates/updates the skill directly from the plan content (which is a full SKILL.md file) instead of spawning an implementation session.
 
+### The skill feedback loop
+
+The three skill jobs are deliberately split by where their evidence comes from:
+
+| Job | Evidence | Answers |
+|-----|----------|---------|
+| `skill-extractor` | memory + recent activity | "What do I keep doing that isn't written down?" |
+| `skill-reviser` | the SKILL.md files themselves | "Is what's written down still true?" |
+| `pr-feedback-harvester` | review comments on the agent's own PRs | "What do reviewers keep telling me I got wrong?" |
+
+Only the harvester reads anything from outside the instance, which makes it the one path by which an outside correction can reach a skill. It classifies each cluster before proposing:
+
+- **General** (commit hygiene, testing discipline, security habits) → a generic skill, or a workspace instruction file such as `AGENTS.md` via `propose_config_change`.
+- **Repo-specific** (build commands, module layout, local conventions) → that repository's own dev skill, creating one if it doesn't exist.
+
+Its tasks use `source="pr-feedback-harvester"`, which is **not** in the `plan_type` auto-detection map — a cluster can produce either a new skill or a revision, so the job passes `plan_type="skill-create"` / `"skill-update"` explicitly. Omitting it silently yields a `generic` plan that spawns an implementation session instead of writing the skill.
+
+Because it ingests third-party text and then proposes edits to the agent's own instructions, its prompt carries an explicit prompt-injection guard: comments are read as evidence of what a reviewer wanted, never as instructions. Keep that guard if you customize the prompt.
+
 ## Persistent Timers
 
 Cron schedules survive server restarts. On startup, the cron service queries `cron_logs` for each job's last successful run and uses that to restore correct timing.
