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 | $0.00443 | $0.00443 |
| Opus 5.5 | $0.00177 | $0.00177 |
| Sonnet 5.5 | $0.00089 | $0.00089 |
| Haiku 4.5 | $0.00044 | $0.00044 |
Grade A, and why
safari-bookmarks-mcp 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 2mo 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.
How it starts
The opening of the file, as written. The whole thing — 35 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
Setup
- Install project dependencies with
uv sync --locked --dev. - Run the full local gate with
just check. - Run supply-chain checks with
just audit. - Install the local pre-push gate with
just install-hookswhen working in a clone.
CI / Local Gates
- Treat
just checkandjust auditas the source of truth for this repo's quality and supply-chain gate. - GitHub-hosted Actions may be unavailable on this account; verify remote Actions with a live probe before relying on them.
- The local pre-push hook runs
just checkandjust audit; bypass only for emergency pushes withSKIP_LOCAL_CI=1.
Dependency Changes
- Treat new runtime dependencies and dependency upgrades as security-sensitive changes.
- Before changing dependencies, inspect the current state with
uv tree --outdated --locked. - Prefer targeted upgrades when fixing a vulnerability; use broad
uv lock --upgradeonly when the resulting diff stays reviewable. - After dependency changes, run
just checkandjust audit. - Do not add new package indexes, direct URLs, Git dependencies, or install scripts unless the user explicitly asks and the risk is documented.
Security Review Focus
- Preserve the MCP server's default write safety: writes require
dry_run=Trueunless the server is started with--confirm-write, and--readonlymust block writes. - Be careful around
~/Library/Safari/Bookmarks.plist; write paths should keep backups, use atomic replacement, and preserve existing file permissions. - Review bookmark tree mutations for cycles, root deletion, malformed paths, and dry-run persistence bugs.
- Keep GitHub Actions least-privilege: explicit permissions, pinned third-party actions, no persisted checkout credentials, and no dependency caches in release or publish jobs.
Review Guidelines
- For dependency bumps, check both behavior and supply-chain risk: lockfile diff, vulnerability audit, release notes for direct dependencies, and CI workflow changes.
- Prioritize bugs that can corrupt bookmarks, silently write to the real Safari plist, leak credentials, or weaken release/publish controls.
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.
