son-of-anton: Skill for Claude Code

.agents/skills/quality-control/SKILL.md

soa-quality-control is a skill for Claude Code, Codex from cesarnml/son-of-anton. It costs 77 tokens per session (1,670 once invoked), scanned C, original, MIT.

A guided quality-control workflow for recording a small, verified fix that reveals a review gap. It links the fix to a completed project phase and records the learning in a review-gap ledger.

In plain words
What is it for?
Use it after closeout for a bounded fix when a human can verify the result and the learning belongs in the project review ledger.
Why use it?
It preserves lessons from completed work so similar gaps can be addressed in future planning or code reviews.

This is cesarnml/son-of-anton's own configuration. It tells Claude Code and Codex how to work on son-of-anton itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything son-of-anton configures →

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 C, and why

soa-quality-control scanned grade C with 1 finding 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 10d ago.

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.

SoA Quality Control

Use this skill for the post-phase quality-control lane after closeout when a small, verified fix exposes a review gap worth recording.

Triggers:

  • /soa quality-control phase-NN: <description>
  • /soa qc phase-NN: <description>
  • /soa quality-control phase-unknown: <description> or /soa qc phase-unknown: <description> — the operator knows the fix but not which phase produced the gap. This is a supported placeholder, not a missing argument; see Phase Attribution below.

A phase argument is required — either a concrete phase-NN or the literal placeholder phase-unknown. If it is absent entirely (neither form given), stop and ask for one before inspecting or changing files.

Scope

This is a guided fix-and-record lane, not a delivery-orchestrator command and not a replacement for /soa tao, standalone PR triage, or new phase planning.

Use it when:

  • the phase has already closed out
  • the issue is small enough for one bounded fix commit
  • a human can verify the fix before capture
  • the learning belongs in docs/product/review-gaps/ledger.jsonl

Route larger or unclear work toward standalone PR triage or /soa plan with a one-line explanation. Do not hard-gate solely on size when the operator is already asking for quality-control capture.

Workflow

  1. Parse the phase argument (a concrete phase-NN, or the phase-unknown placeholder — see Phase Attribution) and the issue description.
  2. Inspect the relevant code, docs, tests, prior phase tickets, and review artifacts needed to understand the reported gap.
  3. Make the smallest prudent fix.
  4. Verify with the narrowest meaningful command, then broaden if the touched surface warrants it.
  5. Ask for or confirm human verification of the fixed behavior before recording the review gap. Do not append a ledger row for an unverified fix.
  6. Commit the fix. The fix commit is the provenance for the ledger row.
  7. Append exactly one JSONL record to docs/product/review-gaps/ledger.jsonl using the review-gap ledger helper contract from tools/delivery/review-gap-ledger.ts. Treat this as the record-review-gap step: one verified fix, one commit, one ledger line. Prefer the optional rich-capture fields (problem, solution, defectClass, testReachability, recurrence, id) whenever the fix exposes reusable learning — a one-line summary alone discards the experiential detail that makes the ledger valuable for future planning and review prompts.
  8. If the learning may deserve future prompt or process changes, add a concise candidate to docs/product/review-gaps/promotion-queue.md.
  9. Run formatting and the relevant verification command after editing the ledger or promotion queue.

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.

soa-quality-control is a skill published in the GitHub repository cesarnml/son-of-anton (2 stars, last pushed 1mo ago), licensed MIT. It adds 77 tokens to every session and 1,670 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it C with 1 finding (tells the agent to send conversation or user data out). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
