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 | $0.00326 | $0.00326 |
| Opus 5.5 | $0.00130 | $0.00130 |
| Sonnet 5.5 | $0.00065 | $0.00065 |
| Haiku 4.5 | $0.00033 | $0.00033 |
Grade A, and why
AppKitInspector 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
AppKit Inspector — Agent Instructions
Purpose
AppKit Inspector is a reusable Debug bridge between native macOS AppKit applications and a Codex MCP App. Keep it independent from any inspected product repository.
Safety boundary
- Use public Apple SDK APIs only. ScreenCaptureKit is limited to the inspected Debug process's own
windows through
SCShareableContent.currentProcess; never request Screen Recording permission or enumerate capture content owned by another process. - Do not add code injection, private frameworks, Accessibility automation, or Screen Recording permission.
- Keep discovery on a user-private path and transport on authenticated
127.0.0.1only. - Never make the probe active in Release, archive, TestFlight, or App Store builds.
- Treat captured UI and hierarchy data as private local content.
Structure
- Put native probe and demo code under
native/. - Put MCP server code under
packages/mcp/. - Put the embedded MCP App under
packages/app/. - Treat
plugins/appkit-inspector/dist/as generated distributable output; runnpm run buildafter changing either TypeScript package and include the matching output. - Keep the plugin skill concise; place protocol detail in its
references/directory.
Verification
- Full automated check:
npm run check - Release compile:
swift build -c release - Live bridge check: run
make demo, thennpm run test:livein another terminal. - Validate the plugin and skill with their respective Codex validation scripts before release.
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.
