run-feedback

A process for recording problems and friction discovered during runs, then sorting them into defects, work items, or noise.

In plain words
What is it for?
Use it after workflows, commands, skills, or tests reveal problems worth keeping. It can file defects in a known-issues ledger and work items in a backlog.
Why use it?
It prevents failed runs and retries from being forgotten. It keeps issue records and backlog indexes synchronized.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

run-feedback scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

The scan reads SKILL.md. This mod also ships 6 executable files (evals/_hashes.py, evals/analyze_rules.py, evals/build_all.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 325 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Run Feedback

Purpose: Errors from runs evaporate today — a gate fails, gets retried, and the knowledge dies with the session. This skill closes the loop: deterministic capture (retro step, hooks, transcript miner) → LLM triage → deterministic filing into the existing ledgers, both of them thin indexes over record files per known-issues-format: defects to docs/issues/ + docs/KNOWN_ISSUES.md, work-items to docs/backlog/ + docs/BACKLOG.md. Filed issues marked auto_fixable: true feed the /heal-issues harness. Machine state lives under the gitignored .agent/feedback/; the repo-visible trace is the ledgers themselves.

1. Red Flags (Anti-Rationalization)

STOP and READ THIS if you are thinking:

  • "I'll append a line to KNOWN_ISSUES.md without creating the issue file" -> WRONG. Lockstep or nothing — the file subcommand writes both or neither, for both ledgers. Never hand-edit one side. Scope of this ban: record files and the index's - **ID** pointer lines. The prefix→category TABLE row in the index preamble is the ONE hand-edit that is yours (§7 step 6) — the script cannot write it.
  • "A work-item is small, its body can just live in the backlog index line" -> WRONG. Both indexes are pointer indexes: one line per record, body in docs/backlog/<slug>.md. An inlined body is how a single entry once reached 7 849 characters — unreadable, undiffable, impossible to close in parts. If a repo really runs a one-file backlog (backlog_layout: "flat"), the engine REFUSES a body it would have to flatten; do not "fix" that by squashing your body into one line — switch the layout or file the body where it belongs.
  • "This finding is obviously a dup, I'll file it anyway for completeness" -> WRONG. A duplicate goes to --as noise --reason "duplicate of <ID>"; the recurrence is already counted by the fingerprint merge.
  • "I'll classify straight from the inbox JSON without running triage" -> WRONG. Dup candidates come from the script (fingerprint + title overlap). Eyeballing misses them.
  • "I'll invent severity HIGH / status handled for a new issue" -> WRONG. The write vocabulary is owned by known-issues-format (SEV-2/3/4/LOW; open/fixed/documented/by-design/mitigated/wontfix). Reading tolerates local extensions; writing never emits them.
  • "The filing is simple, I'll skip --dry-run" -> WRONG. Dry-run first, always — it previews the allocated ID and the exact index line; a mis-filed ID pollutes a hand-maintained ledger.
  • "I'll edit a finding JSON in the inbox by hand" -> WRONG. Only the CLI mutates inbox state; hand edits break fingerprint dedup and the audit trail.
  • "The body I just filed came out malformed, I'll fix the issue file" -> WRONG. Ledger writes are create-only, so a filed body cannot be repaired. The gate now catches the two failures that used to land silently (RF-2, fixed): an unterminated fence and a defect body with no ## Reproduction section are refused at exit 4, and --dry-run echoes the rendered record so you can read the body before it lands. Still compose in a REAL file rather than a heredoc you cannot re-read — the gate checks structure, not whether the prose is right. Landed broken → leave it, tell the human.
  • "The retro step failed, I should retry it / fail the workflow" -> WRONG. The retro is non-blocking by contract: report one line and move on; it NEVER changes the calling workflow's verdict.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

run-feedback is a skill published in the GitHub repository MatrixFounder/Agentic-development (5 stars, last pushed 19d ago), licensed Apache-2.0. It adds 110 tokens to every session and 6,382 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
