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 | $0.00157 | $0.00949 |
| Opus 5 | $0.00078 | $0.00475 |
| Sonnet 5 | $0.00031 | $0.00190 |
| Haiku 4.5 | $0.00016 | $0.00095 |
Grade A, and why
kairos-dev 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 12d 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 — 66 lines — stays where its author put it; the contents beside it link to each section on GitHub.
KAIROS — Developer / Maintainer Umbrella
Developer-scoped, internal. This skill is for maintainers working on
the kairos-mcp repository. End users never need it — they use the kairos
skill. metadata.internal: true keeps it out of user-facing
npx skills add listings while cloned-repo agent hosts still auto-load it
from .agents/skills/.
Everything a maintainer needs is split into focused references. Read the one that matches your task; do not paste their content elsewhere (single source of truth).
Development environment (Docker Compose full stack)
For anything beyond the end-user npx path, run the repository the way CI does: Docker Compose full stack via npm scripts.
- dev-environment.md — spin up the local
full stack (
npm ci,npm run infra:up,dev:deploy), ports, and how it maps to CONTRIBUTING.md. - build-test.md — the authoritative build /
deploy / test contract: npm scripts only, always
dev:deploybeforedev:test. Read this before running any test.

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.

kairos-dev is a skill published in the GitHub repository jakub-plichcinski/kairos-mcp (0 stars, last pushed yesterday), licensed MIT. It adds 157 tokens to every session and 949 once invoked, about $0.0008 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.
