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 | $0.03710 | $0.03710 |
| Opus 5.5 | $0.01484 | $0.01484 |
| Sonnet 5.5 | $0.00742 | $0.00742 |
| Haiku 4.5 | $0.00371 | $0.00371 |
Grade A, and why
co-evolution CLAUDE.md 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.
How it starts
The opening of the file, as written. The whole thing — 225 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Co-Evolution - Cross-AI Document Refinement
Tools for bouncing questions, documents, plans, and code workflows between AI
agents using structured [CONTESTED] / [CLARIFY] markers until convergence.
Default Rule
Three routes, lowest-ceremony first:
- co-evolution (default) — bounce protocol for questions, drafts, plans, specs, arguments, and markdown refinement.
- dev-review — interactive code pipeline (compose → bounce → execute → verify in one session) when the user wants repo files changed, a bug fixed, a feature implemented, or a code diff verified against a plan.
- codex-build — "build with codex": the session plans and reviews, Codex executes detached, with check-ins only at gates. Reach for this when the user wants Codex to grind on a build in the background while the session stays free (the model-ladder flavor of dev-review).
Components
Co-Evolution Skill (skills/co-evolution/)
Default Claude Code skill for questions, ideas, drafts, plans, specs, arguments, prompts, and markdown document refinement.
/co-evolution Stress test this launch plan
Co-Evolve Bouncer (co-evolve-bouncer.sh)
Primary standalone runner. It can compose from a prompt, bounce an existing document, or run staged critique -> defend -> tighten passes.
bash ./co-evolve-bouncer.sh --vanilla "What is the strongest version of this argument?"
bash ./co-evolve-bouncer.sh --vanilla --bounce-only docs/plan.md
bash ./co-evolve-bouncer.sh --vanilla --chain "Should we ship this migration?"
bash ./co-evolve-bouncer.sh --vanilla --adversarial --bounce-only docs/plan.md
bash ./co-evolve-bouncer.sh --vanilla --adversarial --agents claude,claude "Same-model adversarial review"
--adversarial swaps the reviewer's 1-line role for a structured falsification
persona (vendored from the compound-engineering adversarial-document-reviewer;
templates/co-evolve/role-reviewer-adversarial.md). Cross-AI by default; with
--agents claude,claude it is an internal same-model adversarial review. Pair
with --chain or --bounces 3 on dense documents (marker-flooding risk).
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.

co-evolution CLAUDE.md is an instructions file published in the GitHub repository alanshurafa/co-evolution (4 stars, last pushed 29d ago), licensed MIT. It adds 3,710 tokens to every session, about $0.0148 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.
