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 | $0.01468 | $0.01468 |
| Opus 5.5 | $0.00587 | $0.00587 |
| Sonnet 5.5 | $0.00294 | $0.00294 |
| Haiku 4.5 | $0.00147 | $0.00147 |
Grade A, and why
squeez CLAUDE.md scanned grade A with 1 finding 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 20d 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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
curl (local build), npm (pre-built download), cargo install. Release workflow builds universal macOS (lipo), Linux x86_64/aarch64 musl, Windows MSVC on tag push. How it starts
The opening of the file, as written. The whole thing — 75 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Commands
cargo test # all unit tests; `cargo test <name>` for one
cargo build --release
bash build.sh # build + install to ~/.claude/squeez/bin/ + register hooks
# NOTE: re-registers every host adapter, not just Claude Code
bash bench/run.sh # filter-mode benchmarks
python3 bench/verify_tokens.py # real-tokenizer check (tiktoken cl100k_base) vs chars/4

No Makefile — tooling is Cargo-native.
Hard constraints
- Zero runtime dependencies.
Cargo.tomllists onlylibc(Unix signal forwarding). Binary size and CI reproducibility depend on stdlib-only builds. squeez setupmust never shell out to an interpreter. It usedpython3 -cuntil that broke setup on machines withoutpython3on PATH, notably Windows (#190). Usesrc/hosts/settings_json.rs(pure Rust onjson_util).- Every commit needs DCO sign-off — CI enforces via
check-signoff:git commit -s -m "feat(scope): description".
Architecture
Hook-based bash-output compressor for seven CLI agent hosts (Claude Code, Copilot CLI, OpenCode, Gemini CLI, Codex CLI, Pi, Hermes). Intercepts tool invocations and compresses output before the model sees it.
Claude Code hooks: PreToolUse → wrap / budget / prompt-compress / agent-spawn ceiling; SessionStart → init (+ post-compact state restore on source: compact); PostToolUse → track-result + updatedToolOutput rewrite; SubagentStop → feed sub-agent output into SessionContext + release a spawn slot; PreCompact / PostCompact → log + re-arm.
Pipeline (per invocation): smart_filter (ANSI/progress/spinners/timestamps) → dedup (repeats → [×N]) → grouping (≥5 siblings → dir/ N modified) → truncation (head/tail by handler).
Handler dispatch: src/filter.rs detects command type → one of 13+ handlers in src/commands/. extract_name() strips wrappers (npx, bunx, pnpm exec, yarn exec) first. To add one: implement in src/commands/, register in src/commands/mod.rs, add a dispatch arm in src/filter.rs.
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.

squeez CLAUDE.md is an instructions file published in the GitHub repository claudioemmanuel/squeez (220 stars, last pushed 8d ago), licensed Apache-2.0. It adds 1,468 tokens to every session, about $0.0059 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
