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 | $0.00598 | $0.00598 |
| Opus 5.5 | $0.00239 | $0.00239 |
| Sonnet 5.5 | $0.00120 | $0.00120 |
| Haiku 4.5 | $0.00060 | $0.00060 |
Grade A, and why
aiboarding 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 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.

The opening of the file, as written. The whole thing — 46 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Project Purpose
AIBoarding generates, compresses, audits, and maintains AGENTS.md onboarding guidance for AI coding agents.
Stack and Runtime
Portable SKILL.md workflows, Bash hook/tool templates, JSON settings, Markdown docs. Supports Claude Code, Codex, Copilot CLI, Cursor, and OpenCode.
Build, Test, Run
Fast/full suite: bash tests/run.sh.
Validate plugin before release: claude plugin validate . --strict.
Use openspec workflows for planned changes.
Architecture Map
skills/ owns lifecycle reasoning. templates/ owns installed hooks, tools, state defaults, and settings. tests/ verifies deterministic behavior. docs/VERIFICATION.md holds manual runtime protocols.
Flow: skills synthesize guidance and install template copies; hooks detect drift; update-agent-onboarding patches affected guidance or advances only .aiboarding/state.json.
Domain Model
Canonical guidance: AGENTS.md. Claude adapter: CLAUDE.md importing @AGENTS.md. Operational state: .aiboarding/state.json. Configuration: .aiboarding/config.json. Sync pointer remains outside instruction files to prevent drift loops.
Agent Guardrails
Keep hooks deterministic, small, and silent by default. Keep reasoning in skills, not hooks or tests. Do not add self-host-only lifecycle code. Preserve fixtures and public lifecycle behavior. Installed .aiboarding/hooks/ and .aiboarding/tools/ must byte-match templates/.
Known Failure Modes
Do not duplicate canonical guidance in CLAUDE.md. Do not modify instruction files during no-op drift updates. Do not ignore README.md for this repository: it is authoritative onboarding input. Do not replace manual reasoning protocols with inaccurate Bash simulations.
Verification Before Completion
Run bash tests/run.sh. For self-host changes, run bash tests/self-host/test-managed-repo.sh, .aiboarding/tools/check-size-budget AGENTS.md, preservation checks, and audit workflow. Run claude plugin validate . --strict before release work.
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.

aiboarding AGENTS.md is an instructions file published in the GitHub repository gustavo-meilus/aiboarding (2 stars, last pushed 1mo ago), licensed MIT. It adds 598 tokens to every session, about $0.0024 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.
