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 | $0.01289 | $0.01289 |
| Opus 5 | $0.00645 | $0.00645 |
| Sonnet 5 | $0.00258 | $0.00258 |
| Haiku 4.5 | $0.00129 | $0.00129 |
Grade A, and why
Claude-Code-Agent-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 5d 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

Claude Code Working Guide
Project mission
- Maintain a reliable local-first dashboard for Claude Code session monitoring.
- Preserve real-time behavior (hooks -> API -> SQLite -> WebSocket -> UI).
- Keep MCP integration production-ready for local use (
mcp/).
Repo map
server/: Express API, hook ingestion, SQLite access, websocket broadcast (includes optional git upstream checks androutes/updates.js, pluslib/workflow-ingest.jswhich ingests on-disk Workflow-tool run journals — fleets that emit no hooks).client/: React + Vite UI.scripts/: hook installer/handler, import, seed, cleanup utilities. (Update detection lives server-side inserver/lib/update-check.js; the dashboard never restarts itself — users run the printed command, surfaced in the UI and byccam update-check.)mcp/: local MCP server exposing dashboard operations as tools.
Non-negotiable engineering rules
- Preserve existing behavior unless explicitly asked to change it.
- Prefer minimal, reversible diffs.
- Never silently weaken safety controls around destructive actions.
- Keep docs updated when behavior, commands, file locations, or workflows change — apply the
update-project-docsskill automatically at the end of every change-set that alters behavior, config, interfaces, events, schema, CLI commands, or features (do not wait to be asked). - Apply the
i18n-parityskill whenever a change touches localized content — new/changed UI copy or i18n keys,README.md,wiki/index.html, or docs the READMEs and wiki mirror — and work through its new-language checklist whenever adding a language. English is the source of truth on all five localization surfaces (dashboard keys, wiki, mirrored READMEs, language switchers, locale-aware formatting); every supported language ships the change in the same PR. Verify withbash .claude/skills/i18n-parity/scripts/i18n-audit.sh. - Apply the
push-to-forked-prskill whenever updating a PR whose head branch lives on a fork —originhere is the upstream, so a plaingit push originupdates the wrong branch and leaves the PR untouched. - Apply the
version-releaseskill for every release bump: patch for backward-compatible fixes/small improvements, minor for larger backward-compatible capabilities, and major for breaking/fundamental changes; synchronize root, desktop, OpenAPI, snapshots, and generated plugin metadata, create or reuse the matchingv<version>GitHub milestone, and assign the release PR plus linked closing issues to it. - Every applicable source file you create or update (
.js/.ts/.tsx/.cjs/.mjs/.py/.sh/.css) must start with the copyright/authorship header — file overview + the exact line@author Son Nguyen <[email protected]>. Formats and audit script:.claude/skills/file-headers/(verify withbash .claude/skills/file-headers/scripts/check-headers.sh). This binds every coding agent (Claude Code, Codex, or others).
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.
