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 | $0.00178 | $0.00178 |
| Opus 5.5 | $0.00071 | $0.00071 |
| Sonnet 5.5 | $0.00036 | $0.00036 |
| Haiku 4.5 | $0.00018 | $0.00018 |
Grade A, and why
intern-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.
What it actually says
AGENTS.md
Scope
This repository owns the local TryIntern MCP package. TryIntern and Platform backend APIs remain in Firstlanding.
Verification
Run npm run check for source changes. Run npm run test:harnesses when
changing packaging, the executable, or Codex/Claude installation guidance.
When Firstlanding's runtime contract changes, run
node scripts/runtime-contract.mjs sync <firstlanding-path>, verify it with
npm run check:runtime-contract -- <firstlanding-path>, and update both
repositories together.
The MCP uses stdout only for protocol frames. Diagnostics belong on stderr. Keep explicit stdin and signal shutdown so preview processes and snapshots are always cleaned up.
Git
Do not commit or push unless the user explicitly asks. Rebase feature branches
against origin/main before updating a pull request.
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.
