worker-code

worker-code is a skill for Claude Code, Codex from megamen32/LastHumanCommit. It costs 83 tokens per session (518 once invoked), scanned A, original, MIT.

A procedure for making a small, complete code change along the real path used by the product.

In plain words
What is it for?
Use it for bounded features, integrations, API endpoints, user-interface flows, adapters, and production-path changes.
Why use it?
It reduces unnecessary research and edits while requiring proof that the assigned behavior works and that important existing behavior still works.

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

worker-code 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 1mo 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.

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.

Worker Code

Implement one accepted business vertical. Lead owns route and integration.

Procedure

  1. Confirm the accepted outcome, actual consumer, allowed paths, exclusions, and cheapest sufficient proof.
  2. Search the reusable code map with the sibling Worker Research tool, then verify relevant locations with targeted rg. Do not repeat broad research already captured as fresh verified knowledge.
  3. Trace the production call chain before editing an adjacent adapter, fixture, abstraction, or test double.
  4. Use the Ponytail shortcut without a ritual: omit speculative work; reuse existing code, stdlib, platform features or an installed dependency before writing the smallest new implementation that satisfies the accepted result.
  5. Run the real or closest claim-matching canary early. Fix only the first claim-blocking failure and add proportional direct-regression evidence.
  6. If the patch changes a durable production path, owner, or config location, resolve ../worker-research/scripts/code_map.py from this skill and upsert the affected key. Do not record ordinary task progress.
  7. Stop when the assigned claim is proven.

Lead interaction

Ask Lead whenever its broader user context can change behavior, product choice, scope, proof strength, ownership, or a consequential action. Send concise evidence, recommendation/default, parallel-safe work, and the exact blocked action through a non-blocking parent transport; continue edits valid under every plausible answer.

At each 20-minute checkpoint report measured timing, changed files, business delta, blocker, whether the route remains shortest, and the smallest next action. The checkpoint redirects work; it does not kill the Worker.

Do not

  • Do not implement horizontal completeness before the first usable path.
  • Do not redesign, refactor, harden, document, or add compatibility work unless the current business claim requires it.
  • Do not treat compilation or unit tests as user-facing proof.
  • Do not trust a graph, context index, code map, or old task card over current source and the latest user outcome.

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.

worker-code is a skill published in the GitHub repository megamen32/LastHumanCommit (2 stars, last pushed yesterday), licensed MIT. It adds 83 tokens to every session and 518 once invoked, about $0.0003 per session on Opus 5.5. 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.
