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 | $0.00414 | $0.00414 |
| Opus 5.5 | $0.00166 | $0.00166 |
| Sonnet 5.5 | $0.00083 | $0.00083 |
| Haiku 4.5 | $0.00041 | $0.00041 |
Grade A, and why
pin-it-public 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.
What it actually says
Pin It repository guidance
Working practices
- Use
grepfor local text searches. - Use the GitHub CLI (
gh) for GitHub repository, issue, pull request, release, and workflow operations. - Preserve unrelated and uncommitted user changes.
- Keep behavior changes, mechanical cleanup, generated assets, and release work in separate commits.
- Run
npm run checkbefore publishing a code change.
Packaged-app testing
- The local manual-test bundle is
release/mac-arm64/Pin It.app. - Stop the visible app process before replacing a local package.
- Remove the old bundle before running
npm run pack:mac; do not layer a new app bundle over an old one. - Relaunch and verify the exact bundle path rather than relying on the app name,
because duplicate
Pin It.appbundles may exist. - Claude-managed or other MCP helper processes can include the same app binary path in their command line. Do not treat those helpers as proof that the visible UI process is still running.
Local packages are ad-hoc signed unless a valid Developer ID identity is available. A rebuild can change the code-signing requirement that macOS TCC associates with Screen Recording permission. If region capture repeatedly asks for permission after a rebuild, verify which app bundle is running and reset only Pin It's Screen Recording grant:
tccutil reset ScreenCapture xyz.justpinit.app
Do not change build.appId to work around a TCC problem. The durable release
fix is stable Developer ID signing and notarization.
Use this only as a local integrity check:
codesign --verify --deep --strict --verbose=2 "release/mac-arm64/Pin It.app"
It does not prove Developer ID signing or notarization.
Pin data lives under the user's Electron app-data directory, not inside the app bundle, so replacing a packaged app should not remove saved pins or images.
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.

pin-it-public AGENTS.md is an instructions file published in the GitHub repository johnnyzhoujz/pin-it-public (4 stars, last pushed 11d ago), licensed MIT. It adds 414 tokens to every session, about $0.0017 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.
