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 | $0.00723 | $0.00723 |
| Opus 5.5 | $0.00289 | $0.00289 |
| Sonnet 5.5 | $0.00145 | $0.00145 |
| Haiku 4.5 | $0.00072 | $0.00072 |
Grade A, and why
claude-skill 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 24d 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.
What it actually says
Agent notes — this repo is the canonical shared knowledge source
All agent-facing knowledge about the Axiom MCP tools and APIs has ONE
canonical home: plugins/axiom/skills/axiom/references/ in this repo —
tool manuals under tools/, the @axiom_ai/api surface + method
allowlists, the action vocabulary, and the shared browser-automation
rules. Two audiences consume it:
- Desktop Claude users — via the axiom skill itself.
- The OpenHands configure agent — via GENERATED copies:
the backend's embedded agent tools (in every agent conversation's
system prompt) and the agent sandbox image's
tools-*.md+AXIOM_AGENT_SKILL.md(built from a template that pulls shared prose with<!-- INCLUDE <references-path> -->markers).
Rules when editing knowledge here:
- Never edit a synced or generated copy in the consumer repos (each
carries a do-not-edit banner). Edit the canon here — or the sandbox
template, for OpenHands-runtime-specific prose. The consumers are
regenerated by the maintainers' sync step, which writes into the backend
and infrastructure repositories: that is a deliberate OpenHands deploy step
on those repos' own branches, NOT something to run as part of an edit here (this skill also ships to the desktop app on its
own).
--checkreporting drift until that deploy is the expected state. - Content true for BOTH audiences belongs in
references/; only runtime-specific prose stays in an actor file or template. The desktop skill's account-setup/key-minting content must NEVER flow to the OpenHands agent (its credential is an injected job-scoped secret). - A canon edit has deploy costs: lar deploy (new conversations embed
it; parked warm slots self-invalidate via prompt_hash) and a sandbox
image rebake for on-disk copies. Batch edits; bump the version in
package.jsonand add a CHANGELOG entry — consumers pin to it. references/action-vocabulary.jsonis GENERATED, never hand-edited:npm run build:vocabularyderives it from the widget catalogue axiom_mcp ships (its nestedaxiom_builder_irsubmodule, not the sibling checkout of the same repo). Run it whenever that pin moves — otherwise agents author widgetscompile_irrejects as unknown, and never learn about new ones.npm run build:vocabulary:checkis the drift detector and runs in the test suite, so CI catches a stale file on its own. Fields this repo adds on top of the source (WidgetBotCreate'sisLooping/afterLoopUpdate) are carried forward by the generator. Its schema is also an API: axiom_mcp'slist_actionsreads the same catalogue.- Verify headlessly before shipping:
npm run verify— the single gate (generated-copy drift check + lint + the full jest suite; no network, no key). A change here isn't done until it's green. - Agent precedence, by design: job brief > actor skill > tool manuals. Brief-level policy (never-invent user values, ask-on-ambiguity) lives in the backend's agent job brief, not here.
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.

claude-skill AGENTS.md is an instructions file published in the GitHub repository axiom-browser-automation/claude-skill (4 stars, last pushed 25d ago), licensed ISC. It adds 723 tokens to every session, about $0.0029 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 2026-09-24.
