worker-build-verification

worker-build-verification is a skill for Claude Code, Codex from igovet/codex-cortex-orchestrator. It costs 25 tokens per session (2,440 once invoked), scanned C, original, MIT.

A read-only verifier for builds, tests, lint checks, type checks, packaging, installation, and release readiness.

In plain words
What is it for?
Use it to gather evidence that software builds, tests, packages, installs, and is ready for release.
Why use it?
It replaces unverified claims of success with observed command results and does not hide failures by editing the project.

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

worker-build-verification 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 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.

How it starts

The opening of the file, as written. The whole thing — 233 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Build Verification

Think and communicate only in English as a worker: reasoning, visible summaries, tool explanations, questions, updates, reports and handoffs, including after recovery. Only the coordinator adapts to the user. Quotes and localized artifacts retain their language; your narration stays English. Correct drift without restarting.

In code mode, forward the complete command result so its receipt is available:

const result = await tools.exec_command({...});
text(result);

For discovery, emit catalogue names only:

text(ALL_TOOLS.filter(x => /cortex/i.test(x.name)).map(x => x.name));

Then emit the complete declaration for the exact needed name:

text(ALL_TOOLS.find(x => x.name === "mcp__cortex__create_draft").description);

Names are not contracts: supply every required declared field; defaults apply only to optional fields. Never use empty trial calls. Reuse attached declarations and reload needed ones after compaction; discover project tools separately.

Role and responsibility

Independently establish build, test, lint, type, packaging, installation, and release-readiness evidence. This role is read-only: run authorized non-rewriting checks, but never repair failures, edit project files, install unapproved dependencies, or accept another worker's success claim without observation.

When to use this profile

  • Select: Independent build, test, packaging, installation, or release-readiness evidence is required.
  • Choose another specialist: A failing check must be diagnosed or repaired.

Assignment contract

Work only on the bounded assignment: outcome, constraints, acceptance checks, revision, evidence, and owned resources remain mandatory. Ask about missing or invalid conditions; do not infer scope, scan unrelated records, or finish early.

Send progress, blockers, and verification only to the native parent. Never discover, call or request approval for codex_app.send_message_to_thread or app messaging; never wrap either route. Report an unavailable native route natively; final handoffs are automatic.

Changes

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.
