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 | $0.01218 | $0.01218 |
| Opus 5 | $0.00609 | $0.00609 |
| Sonnet 5 | $0.00244 | $0.00244 |
| Haiku 4.5 | $0.00122 | $0.00122 |
Grade A, and why
claude-fleet-monitor 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 4d 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 — 100 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Claude Fleet Monitor
Fleet monitoring for Claude Code and Codex sessions. The core is pure Python and cross-platform. The approved Pi integration may package an optional dependency-free JavaScript extension.
See docs/SDLC.md for the adopted agent workflow, approval gates and active planning.

Modules
hook.py: Claude Code and Codex hook handler. Receives events via stdin JSON, writes session status to the fleet directory, and tags the source agent. Captures terminal type and PID per session.discovery.py: Shared module. Cross-platform process discovery (/procon Linux,lsof/pson macOS,taskliston Windows). Reads/deduplicates/cleans session files. Used by all consumers.models.py: Typed data models.SessionStatusenum,FleetSessionfrozen dataclass,parse_session()converter,format_age()utility.mcp_server.py: FastMCP server exposing fleet tools to Claude Code and Codex sessions.tui.py: Textual-based interactive dashboard (FleetMonitorApp). Polling, search/filter, desktop notifications, session focus.widgets/session_table.py:SessionTable(DataTable)widget with status-colored rows. Shared between standalone TUI and tongs screen.views/fleet_screen.py:FleetScreen(Screen)for embedding in tongs. Same features as standalone but escape pops back.tongs_plugin.py:FleetMonitorPlugin(TongsPlugin)ABC implementation. Optional tongs dependency. Registers command palette entry and screen.focus.py: Session lookup and PID resolution. Delegates to terminal APIs for actual focus.cli.py: Entry point forclaude-fleetcommand. Installs Claude Code and Codex hooks and MCP configuration, then delegates to tui/focus/status.
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.

claude-fleet-monitor CLAUDE.md is an instructions file published in the GitHub repository andre-motta/claude-fleet-monitor (1 stars, last pushed 4d ago), licensed MIT. It adds 1,218 tokens to every session, about $0.0061 per session on Opus 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.
