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 | $0.00758 | $0.00758 |
| Opus 5.5 | $0.00303 | $0.00303 |
| Sonnet 5.5 | $0.00152 | $0.00152 |
| Haiku 4.5 | $0.00076 | $0.00076 |
Grade B, and why
matilha-skills AGENTS.md scanned grade B with 1 finding 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.
Reads agent configuration directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.
You are reading this because Matilha is available. On Codex CLI, skills load natively — when a skill's description matches user intent, follow its instructions. Some skills dispatch subagents; Codex requires `multi_agent How it starts
The opening of the file, as written. The whole thing — 53 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Matilha — Cognitive + Methodological Harness
You lead. Agents hunt. A harness for building complex projects with AI.
Matilha preserves discipline across multi-week projects by activating phase-appropriate skills automatically. The human stays in the decision seat (intent, gates, judgment); the agents execute (parallel worktrees, per-SP focus, gated output).
How this loads in Codex (and for contributors)
You are reading this because Matilha is available. On Codex CLI, skills load natively — when a skill's description matches user intent, follow its instructions. Some skills dispatch subagents; Codex requires multi_agent = true in ~/.codex/config.toml for subagent features. See docs/platform-tool-mapping.md for exact Codex tool equivalents (spawn_agent / wait / close_agent, etc.).
For contributors authoring new skills: read docs/matilha/skill-authoring-guide.md before writing. Strict frontmatter is load-bearing — sloppy descriptions produce invisible skills.
Phases (0-70)
Matilha organizes work across 8 phases. Each has a skill entry point.
| Phase | Purpose | Entry skill |
|---|---|---|
| 0 | Project state + next action | matilha-howl |
| 10 | Discovery / research | matilha-scout |
| 20-30 | Spec + plan authoring | matilha-plan |
| 40 | Dispatch + merge (waves, SPs) | matilha-hunt, matilha-gather |
| 50 | Quality review | matilha-review (Wave 3c planned) |
| 60 | Knowledge capture | matilha-den |
| 70 | Reusable artifacts | matilha-pack |
| init | Bootstrap new project | matilha-init |
| design | UX/UI guidance (cross-phase) | matilha-design |
See docs/matilha/naming-conventions.md for skill prefix rules and docs/matilha/companions-contract.md for how companion packs (UX, growth, design, security, harness) plug in.
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.

matilha-skills AGENTS.md is an instructions file published in the GitHub repository danilods/matilha-skills (2 stars, last pushed 5mo ago), licensed MIT. It adds 758 tokens to every session, about $0.0030 per session on Opus 5.5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
