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 | $0.00295 | $0.00295 |
| Opus 5.5 | $0.00118 | $0.00118 |
| Sonnet 5.5 | $0.00059 | $0.00059 |
| Haiku 4.5 | $0.00030 | $0.00030 |
Grade A, and why
csl-agent-kit AGENTS.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 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
Project Agent Rules
Rule Changes
- After modifying any skill package under
skills/or.agents/skills/, load the built-inskill-qualitySkill and runnode skills/meta/skill-quality/scripts/check.js <skill-dir>from the workspace root for every changed package before claiming completion. Use--all --workspace .only for broad Skill changes. Quality failures block completion; review and disclose any accepted warning that affects confidence. - After modifying non-skill rules (AGENTS.md, CLAUDE.md, SOPs under
~/.csl-agent-kit/sops/orskills/meta/agent-sops/sops/, hooks),skill-qualitydoes not apply. Verify instead by: (1) structural consistency with existing files of the same kind, and (2) for SOPs — matching the YAML header fields and section template of peer SOPs. Runadversarial-reviewor request human review only when the user explicitly asks for that review; high risk alone does not trigger it.
Task Files
- Store each task in
tasks/tasks/<task-slug>.mdand add its title, current status, and relative link at the top of the newest-firsttasks/tasks.mdindex. - Update only the owning task file and its exact index entry; do not rewrite unrelated task records. Add new lessons at the top of
tasks/lessons.md.
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.
