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 | $0.00614 | $0.00614 |
| Opus 5.5 | $0.00246 | $0.00246 |
| Sonnet 5.5 | $0.00123 | $0.00123 |
| Haiku 4.5 | $0.00061 | $0.00061 |
Grade A, and why
session-handoff-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.

Repository Guidelines
Project Structure & Module Organization
The project is a Node.js 24+ TypeScript MCP server. Production code lives in src/, organized by responsibility: mcp/ exposes tools, services/ coordinates use cases, checkpoint/ owns schemas and Markdown rendering, project/ resolves project identity, and storage/, security/, config/, and git/ provide infrastructure. Tests live in tests/ and generally mirror a subsystem, for example tests/checkpoint-service.test.ts. Normative behavior belongs in docs/SDD.md; architectural rationale belongs in docs/decisoes-v1.md. Generated output (dist/, coverage/, package archives) must not be committed.
Build, Test, and Development Commands
pnpm install --frozen-lockfile: install exactly the locked dependencies.pnpm dev init --help: run the TypeScript CLI directly during development.pnpm build: compilesrc/intodist/.pnpm test: build and run the Vitest suite once.pnpm test:coverage: run tests with the enforced V8 coverage thresholds.pnpm check: run typecheck, ESLint, Prettier verification, build, and tests.npm pack --dry-run: verify the public npm package contents.
Run pnpm check before submitting changes.
Coding Style & Naming Conventions
Use strict TypeScript and ES modules. Prettier controls formatting; do not hand-align code. ESLint enforces typed rules and type-only imports. Use two-space indentation, camelCase for values/functions, PascalCase for types/classes, and kebab-case filenames such as checkpoint-store.ts. Keep MCP adapters thin and place business behavior in services. Represent recoverable failures with SessionHandoffError and stable uppercase codes.
Testing Guidelines
Vitest files use the *.test.ts suffix. Add unit tests for validation and edge cases, plus integration coverage for MCP or filesystem behavior. Use temporary directories and fictitious project data; never include real client paths or secrets. Coverage must remain at least 80% statements, 70% branches, 85% functions, and 80% lines.
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.
