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 | $0.02346 | $0.02346 |
| Opus 5.5 | $0.00938 | $0.00938 |
| Sonnet 5.5 | $0.00469 | $0.00469 |
| Haiku 4.5 | $0.00235 | $0.00235 |
Grade A, and why
refact 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.
How it starts
The opening of the file, as written. The whole thing — 164 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Verification Commands
Always verify your changes compile and pass tests before finishing. Both engine and GUI builds are heavy — plan accordingly.
Engine (refact-agent/engine/)
cd refact-agent/engine
# Fast check — type/borrow errors only (~1-3 min, no codegen)
cargo check
# Unit + doc tests (~3-8 min first build, ~1-3 min incremental)
cargo test --lib && cargo test --doc
# Full release build (~10-20 min cold, ~2-5 min incremental)
# LTO + opt-level=z + strip — very slow from scratch
cargo build --release
⚠️ First build compiles ~85 crates + 7 tree-sitter parsers + SQLite. Expect 10-20 minutes cold. Incremental builds are much faster. CI runs cargo test --release on 7 platform targets.
Python integration tests (tests/*.py) require a running refact-lsp instance — don't run them as a quick check.
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.
