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 | $0.08401 | $0.08401 |
| Opus 5.5 | $0.03360 | $0.03360 |
| Sonnet 5.5 | $0.01680 | $0.01680 |
| Haiku 4.5 | $0.00840 | $0.00840 |
Grade A, and why
product-cli CLAUDE.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 — 523 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md — Product CLI
What is this project?
Product is a Rust CLI and MCP server for the Product Framework — the open
What/How specification graph (docs/product-framework-open.md, currently
v1.9.1). It captures and verifies a product's What (domain model, event model,
Deciders, Projectors, systems, triggers, UI/AIO model) and How (contracts,
reification, delivery), all under .product/. Every product has one home,
.product/products/<name>/; the reference What lives in
.product/products/product-cli/.
Graph-only. This repo was pivoted to the framework graph alone. The former FT/ADR/TC knowledge-graph tool (the
adr/test/gap/drift/conformance/implement/verifycommands,docs/{features,adrs,tests}, and the meta-graph engine) has been removed. Don't reach for those commands or dirs. Note the currentproduct featurecommand is unrelated — it is the §7.1 delivery feature (see Vocabulary below), not the old FT-XXX artifact.
Build & Test
cargo build # compile
cargo t # full suite, runs every binary (alias in .cargo/config.toml)
cargo clippy -- -D warnings -D clippy::unwrap_used # lint (zero unwrap policy)
Always run cargo t, never plain cargo test. Plain cargo test stops at
the first failing binary and skips the rest. The t alias is test --no-fail-fast (.cargo/config.toml): it runs every test binary and reports
the complete result set at the end.
Suite composition (~500 tests):
| Binary | What it covers |
|---|---|
cargo test -p product-core --lib |
pf unit tests (the framework graph, in #[cfg(test)] mod tests) |
cargo test -p product-mcp |
MCP registry + framework tool handlers (stateless + phase-gated session) |
--test framework |
assert_cmd-driven framework CLI scenarios (tests/framework.rs) |
--test code_quality_tests |
fitness gates: file length ≤ 400, function length, SRP, module structure |
product-core/tests/property |
proptest over fileops/init |
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.

product-cli CLAUDE.md is an instructions file published in the GitHub repository Hafeok/product-cli (6 stars, last pushed 1mo ago), licensed MIT. It adds 8,401 tokens to every session, about $0.0336 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.
