Claude Code Agent Monitor is a dashboard that records and displays activity from Claude Code and Codex coding-agent sessions, including tool use and subagent coordination. It is for people who need live visibility into agent work through a web interface or native desktop app. The catalogue entries extend Claude Code with skills, commands, agents, plugins, instructions, hooks, and settings related to the monitor.

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 | $0.00999 | $0.00999 |
| Opus 5.5 | $0.00400 | $0.00400 |
| Sonnet 5.5 | $0.00200 | $0.00200 |
| Haiku 4.5 | $0.00100 | $0.00100 |
Grade A, and why
Claude-Code-Agent-Monitor 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 7d 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.

Codex Project Instructions
Project intent
- Keep this repository a stable, local-first Claude Code monitoring platform.
- Maintain correctness across hooks, API, DB, websocket, UI, and MCP integration.
Priorities
- Correctness over cleverness.
- Small, scoped, reversible diffs.
- Preserve existing behavior unless change is requested.
- Update docs whenever workflow or architecture changes — follow
.claude/skills/update-project-docs/automatically at the end of every change-set (concise README landing, README-EN + CN/VN/KO/ES full guides, ARCHITECTURE, wiki + i18n + cache bump, server/client READMEs, docs/*). - Apply
.agents/skills/i18n-parity/(mirrored from.claude/skills/i18n-parity/, which also holds its scripts) whenever a change touches localized content (UI copy or i18n keys,README-EN.md, a localized full guide,wiki/index.html, or docs the guides and wiki mirror), and work through its new-language checklist when adding a language.README.mdis an English-only landing page;README-EN.mdis the full-guide source of truth. Every supported language (en/zh/vi/ko/es) ships full-guide changes in the same PR. Verify withbash .claude/skills/i18n-parity/scripts/i18n-audit.sh. - Apply
.agents/skills/push-to-forked-pr/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
.agents/skills/version-release/for every release bump: patch for backward-compatible fixes/small improvements, minor for larger backward-compatible capabilities, and major for breaking/fundamental changes; synchronize every shipping release surface, create or reuse the matchingv<version>GitHub milestone, and assign the release PR plus linked closing issues to it. The automated workflow input names aremajorfor the first component,intermediatefor the middle component, andminorfor the last component. - Every applicable source file you create or update (
.js/.ts/.tsx/.cjs/.mjs/.py/.sh/.css) must start with the authorship header: a truthful file overview plus the exact line@author Son Nguyen <[email protected]>. See.claude/skills/file-headers/and.claude/rules/file-headers.md; verify withbash .claude/skills/file-headers/scripts/check-headers.sh.
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.
