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 5.1 | $0.00035 | $0.00300 |
| Opus 5.5 | $0.00014 | $0.00120 |
| Sonnet 5.5 | $0.00007 | $0.00060 |
| Haiku 4.5 | $0.00003 | $0.00030 |
Grade A, and why
worker-campaign-cheap-reliability 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 2mo 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 Campaign Cheap Reliability
Goal
Turn "cheap worker feels degraded" into measured failure classes and gated mitigations.
Phases
- Baseline: run
npm test,npm run codex:audit -- --since-minutes=60, and collect recent failed episodes. - Instrument: ensure reliability profile, episode summary, receipt abnormal verdict, and tool metrics exist.
- Gate: use
strictfor normal risky edits andcriticalfor security, release, migration, or broad refactors. - Review: send semantic-risk cases to main-thread or strong-model review.
- Promote: only make a warning into a hard block after eval cases prove low false-positive risk.
Wrong Paths To Fence Off
- Do not rely on more output tokens as thinking time.
- Do not expose all tools to a weak model by default.
- Do not trust a model-created Observation without runtime receipt.
When Not To Use
Do not use this for one isolated failed command. Use worker-debugging-playbook.
Verification
npm testnpm run codex:guard- Compare trajectory scores before and after a change.
Provenance and maintenance
Add real user feedback cases as eval episodes before tightening blocking gates.
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-campaign-cheap-reliability is a skill published in the GitHub repository sorryorc/mcp-codex-worker (2 stars, last pushed 1mo ago), licensed MIT. It adds 35 tokens to every session and 300 once invoked, about $0.0001 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.
Other skills, from other repositories
cost-mode
Cost-conscious Claude Code mode. Cuts visible output and routes simple work to cheaper models 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…
refocusing
Use when a long-running agent may have lost the product outcome, when context was compacted, when work has crossed a major boundary, or when a fresh path-based trace is needed before the next consequential action. Not for fresh-session orientation, waking an idle seat, or checkpoints.
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.
gitnexus
A code-graph analysis add-on for examining an existing codebase, including symbols, call paths, execution flows, and effects across repositories. It can query GitNexus through its command-line or MCP interfaces.
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.
