Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00036 | $0.00347 |
| Opus 5 | $0.00018 | $0.00173 |
| Sonnet 5 | $0.00007 | $0.00069 |
| Haiku 4.5 | $0.00004 | $0.00035 |
Grade A, and why
worker-debugging-playbook 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 3d 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.
What it actually says
Worker Debugging Playbook
Symptom Table
| Symptom | First check | Likely cause | Next action |
|---|---|---|---|
Job not found |
Job TTL and id source | Expired or wrong id | Re-run start, capture id in the caller |
Receipt says missing_artifact |
Receipt bytes and refs | Large output without artifact | Fix tool to save artifact before returning |
scoped_patch violation |
Changed files vs paths | Worker edited outside scope | Narrow prompt and rerun with scoped paths |
| Checks passed but output feels wrong | Episode and semantic risk | Semantic failure | Use strict or critical tier review |
| Repeated revise passes | Reasoning blockers | Stalled repair loop | Escalate model or stop for main review |
Minimal Triage
- Read compact
getoutput first. - If receipt has artifact refs, inspect slices instead of full logs.
- Check
episode.trajectory_scoreand missing gates. - Run the smallest failing check outside the worker if needed.
When Not To Use
Do not use this for planned feature work. Use worker-change-control first.
Verification
npm run codex:audit -- --since-minutes=60npm run stats:gate
Provenance and maintenance
Refresh symptoms with rg -n "Job not found|missing_artifact|scoped_patch|revise" src scripts.
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-debugging-playbook is a skill published in the GitHub repository sorryorc/mcp-codex-worker (2 stars, last pushed 15d ago), licensed MIT. It adds 36 tokens to every session and 347 once invoked, about $0.0002 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.

cost-mode
Cost-conscious Claude Code mode. Reduces output tokens 40-70% and overall costs 30-60% by enforcing concise responses, smart model routing, and efficient workflow patterns. Keeps full technical accuracy. Activate with /cost-mode or "enable cost mode". Auto-triggers on mentions of budget, cost, tokens, or spending.
rulesync
Generates and syncs AI rule configuration files (.cursorrules, CLAUDE.md, copilot-instructions.md) across 20+ coding tools from a single source. Use when syncing AI rules, running rulesync commands, importing or generating rule files, or managing shared AI coding configurations.
establishing-project-context
Use when the user asks to establish shared project language, or project work exposes a conflicting, renamed, or deprecated domain term that needs active semantic modeling. Routine small tasks stay on the fast path.
