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 | $0.00844 | $0.00844 |
| Opus 5.5 | $0.00338 | $0.00338 |
| Sonnet 5.5 | $0.00169 | $0.00169 |
| Haiku 4.5 | $0.00084 | $0.00084 |
Grade B, and why
airails AGENTS.md scanned grade B with 2 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 yesterday.
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.

Other skills' SKILL.md files reveal prompts, capabilities and secrets that should be invisible to peers.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

The opening of the file, as written. The whole thing — 80 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Installing airails.dev Skills
Instructions for AI agents asked to install, list, or remove the skills in this repository.
A skill is a directory containing a SKILL.md, organized under bce/, java/, web/, and documentation/. Installation means copying the skill directory — preserving its folder name — into the skills directory of the target agent.
Skill Directories per Agent
| Agent | Skills directory |
|---|---|
| claude | ~/.claude/skills |
| vibe | ~/.vibe/skills |
| kiro | ~/.kiro/skills |
| copilot | ~/.copilot/skills |
| codex | ~/.agents/skills |
| goose | ~/.config/goose/skills |
How to Install
Pick the first applicable option:
1. Interactive terminal available (user is driving)
Ask the user to run ./installSkills from the repository root. Do not run it from an agent shell — it requires an interactive terminal (System.console()) and exits with interactive terminal required when stdin is piped or non-TTY.
2. Agent shell (no TTY)
Copy the skill directories directly. From the repository root:
mkdir -p ~/.claude/skills
find . -name SKILL.md -not -path './target/*' | while read f; do
cp -R "$(dirname "$f")" ~/.claude/skills/
done
Replace ~/.claude/skills with the target agent's directory from the table above. Copying overwrites an existing skill of the same name — acceptable, since this repository is the source of truth for these skills.
3. No JDK, no git
Download the per-agent zip from the rolling skills release and unzip into the home directory:
curl -fsSLO https://github.com/AdamBien/airails/releases/download/skills/airails-claude.zip
unzip -o airails-claude.zip -d ~
Each zip contains all skills with the agent's skills directory baked into the entry paths (airails-claude.zip, airails-vibe.zip, airails-kiro.zip, airails-copilot.zip, airails-codex.zip, airails-goose.zip).
Agent-neutral bundles hold a per-stack subset under a plain skills/ prefix and unzip into the agent's skills directory instead of the home directory: airails-java-server.zip, airails-java-cli.zip, airails-web.zip, airails-migrations.zip, plus the add-ons airails-sbce.zip (spec-driven workflow) and airails-documentation.zip. Prefer the bundle matching the project when one does, since it keeps unrelated skills out of the agent's context:
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.

airails AGENTS.md is an instructions file published in the GitHub repository AdamBien/airails (62 stars, last pushed yesterday), licensed MIT. It adds 844 tokens to every session, about $0.0034 per session on Opus 5.5. A static security scan graded it B with 2 findings (enumerates other installed skills, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
