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 | $0.00733 | $0.00733 |
| Opus 5 | $0.00367 | $0.00367 |
| Sonnet 5 | $0.00147 | $0.00147 |
| Haiku 4.5 | $0.00073 | $0.00073 |
Grade A, and why
ai-agents-skills 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 8d 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 — 52 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
This repository ships five integrations from the same source tree: Claude Code, Codex, Cursor Agent CLI/IDE, Hermes Agent, and Prime Agent:
.claude-plugin/plugin.json+.claude-plugin/marketplace.json— Claude Code manifest and marketplace entry..codex-plugin/plugin.json— Codex plugin manifest..cursor-plugin/plugin.json+.cursor-plugin/marketplace.json— Cursor Agent CLI/IDE manifest and marketplace entry.plugin.yaml+__init__.py— Hermes manifest and Python registration adapter. It registers the shared skills read-only under theai-agents-skills:namespace and maps compatible lifecycle hooks.package.json+extensions/prime-adapter.ts— Prime Agent capability-package manifest and lifecycle adapter. It exposesskills/andagents/through the Prime package resource API, then maps only lifecycle events Prime supports.
Conventions
- Shared skills live under
skills/and are used by all four integrations — don't fork or duplicate a skill per runtime. - Runtime-specific lifecycle hook maps stay separate:
hooks/hooks.json(Claude Code),hooks/codex-hooks.json(Codex, declared explicitly in.codex-plugin/plugin.json), andhooks/cursor-hooks.json(Cursor — routes every event throughhooks/cursor-adapter.sh, which normalizes Cursor's payload field names into the shape the sharedtg-*.sh/abbr-inject.shscripts already expect). Do not merge them, and put any Cursor-specific translation logic in the adapter, not in the shared scripts. Cursor has noNotification/PermissionRequestequivalent — the "needs attention" ping is intentionally not wired for Cursor; see docs/superpowers/specs/2026-07-31-cursor-plugin-design.md. - Hermes lifecycle translation belongs in the root
__init__.py; shared shell hooks continue to consume the normalized Claude-shaped JSON payload. Hermes has no permission/idle notification event, so that ping degrades safely just as it does under Cursor. - When changing shared behavior (a skill, an agent, a hook script), preserve
all five integrations — verify the change still works for Claude Code,
Codex, Cursor, Hermes, and Prime Agent, and update every manifest the change
affects metadata for (e.g.
version). - Codex hooks must be declared explicitly as
./hooks/codex-hooks.jsonso Codex does not auto-discover the Claude Code-specifichooks/hooks.json. Plugin hooks require the user's Codex trust review before they can execute. - Script-bearing skills must resolve the root through
AI_AGENTS_SKILLS_ROOT, with Claude/Codex/Cursor root fallbacks. Hermes setsAI_AGENTS_SKILLS_ROOTduring plugin registration. - Run
pytest -q tests/test_hermes_plugin.pyand an isolatedhermes plugins install file://... --enablesmoke test for Hermes changes. - All authored repository text (skills, docs, manifests, commit messages) is English.
- See
README.mdfor install/enable/verify steps for each runtime.
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.

ai-agents-skills AGENTS.md is an instructions file published in the GitHub repository Xakki/ai-agents-skills (6 stars, last pushed 18d ago), licensed MIT. It adds 733 tokens to every session, about $0.0037 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.
