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 | $0.07652 | $0.07652 |
| Opus 5.5 | $0.03061 | $0.03061 |
| Sonnet 5.5 | $0.01530 | $0.01530 |
| Haiku 4.5 | $0.00765 | $0.00765 |
Grade C, and why
claudectl CLAUDE.md scanned grade C with 2 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 yesterday.
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.
Reaches for credential fileshighPrivilege escalation
SSH keys, cloud credentials, git-credentials, .npmrc, /etc/shadow: reading these is how a config file becomes a credential leak.
- `deny.rs` — the "excluded" half of "tracked and not excluded": denied names and prefixes (`.env*`, `.netrc`, ssh keys, `credentials`), extensions (`jsonl`, keys/certs, `sqlite`/`db`), and path segments (`.claude`, `.cl Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
- `jev.rs` — the Jev wire contract and nothing else: request build, response parse, `Transport`. Shells out to `curl` (§4.6, zero new crates), but unlike `brain/client.rs` the credential goes on **stdin** via `-H @-`, be How it starts
The opening of the file, as written. The whole thing — 222 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Build & Test
cargo build # Debug build
cargo build --release # Release build, default features (bus+coord+relay+hive) — ~6.3 MB; matches the Homebrew bottle
cargo build --release --no-default-features --features hive # Minimal sync-only build — ~3.5 MB
cargo test # Run all tests
cargo clippy -- -D warnings # Lint (warnings are errors in CI)
cargo fmt --check # Check formatting
Architecture
Workspace layout
This is a Cargo workspace with three crates. Dependencies flow strictly downward — claudectl → claudectl-tui → claudectl-core — and CI enforces it (Layering grep on core, plus standalone build jobs for each crate). Adding upward arrows is what the workspace exists to prevent.
crates/
├── claudectl-core/ # foundational types, IO, the UI↔runtime trait contract
│ # session, discovery, monitor, process, transcript,
│ # models, theme, logger, helpers, history, terminals/,
│ # health, rules, config, hooks, launch, skills, runtime
└── claudectl-tui/ # terminal UI + recording + demo fixtures
# app.rs, ui/*, recorder.rs, session_recorder.rs, demo.rs
# Depends on claudectl-core. Never on the binary.

# main.rs + access/ + brain/ + bus/ + context/ +
# coord/ + hive/ + query/ + relay/ + orchestrator +
# init + commands + config.rs + brain_screen.rs.
# Implements the runtime traits over the real
# subsystems via `src/runtime/`.
UI ↔ runtime contract lives at crates/claudectl-core/src/runtime.rs. Eight traits — SessionSource, BrainView, CoordView, BusView, Actions, BrainReviewView, Orchestrator, HiveActions, plus two stateful handles the TUI owns: BrainDriver, and the DiscoveryListener that HiveActions::start_discovery hands out while the Hive tab is showing — wrapped in a Runtime aggregate. Core-owned DTOs (SessionSnapshot, DecisionSummary, LeaseSummary, HiveViewSnapshot, etc.) so the contract doesn't drag brain / coord / bus types upward. The binary's src/runtime/ provides Live* adapters that implement each trait over the real subsystem.
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.

claudectl CLAUDE.md is an instructions file published in the GitHub repository mercurialsolo/claudectl (202 stars, last pushed yesterday), licensed MIT. It adds 7,652 tokens to every session, about $0.0306 per session on Opus 5.5. A static security scan graded it C with 2 findings (reaches for credential files, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
