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 | $0.01614 | $0.01614 |
| Opus 5.5 | $0.00646 | $0.00646 |
| Sonnet 5.5 | $0.00323 | $0.00323 |
| Haiku 4.5 | $0.00161 | $0.00161 |
Grade A, and why
typemux-cc 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 1mo 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 — 130 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Agent Instructions
Landing the Plane (Session Completion)
When ending a work session, complete the steps below.
WORKFLOW:
- Run quality gates (if code changed) -
make all - Report remaining work - Describe follow-up work without creating issues unless the user explicitly authorizes issue creation
- Report the working tree - Summarize changed files and verification results
- Hand off - Provide context for the next session
Creating issues, committing, pushing, and opening pull requests are separate external mutations. Perform each one only when the user explicitly authorizes that action. An instruction to commit does not authorize a push or pull request, and an instruction to push does not authorize opening a pull request.
typemux-cc - Python Type-Checker LSP Multiplexer for Claude Code
See README.md for project overview. See docs/ARCHITECTURE.md for architecture details.
Build & Quality
# REQUIRED: Run before completing any work
make all # fmt + lint + doc + test (see Makefile)
# Individual commands
make fmt # cargo fmt
make lint # cargo clippy -- -D warnings
make test # cargo test
Verification by change type
Select checks from the final diff:
| Change | Checks |
|---|---|
| Docs only | None locally (CI runs make ci) |
Version fields (Cargo.toml, .claude-plugin/*.json) |
make check-versions (needs jq) |
Rust under src/ |
make all |
| Client-visible LSP sequencing (initialize/initialized, routing, document restoration) | make all + a real-client check via the plugin-test-cycle skill |
install.sh, hooks.json |
No automated coverage; run the hook against a scratch plugin root |
What cargo test cannot see: integration tests drive mock-lsp-backend through a
fake pyright-langserver shim (tests/support/mod.rs). They never exercise a real
Claude Code client or a real type checker.
When reporting, name the commands you ran. "Tests pass" after a partial run is not a report.
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.

typemux-cc AGENTS.md is an instructions file published in the GitHub repository K-dash/typemux-cc (17 stars, last pushed 5d ago), licensed MIT. It adds 1,614 tokens to every session, about $0.0065 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 2026-08-30.
