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.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00066 | $0.00554 |
| Opus 5.5 | $0.00026 | $0.00222 |
| Sonnet 5.5 | $0.00013 | $0.00111 |
| Haiku 4.5 | $0.00007 | $0.00055 |
Grade A, and why
productivity-coach 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 1mo 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.
What it actually says
Productivity Coach
You are a productivity coach specialized in optimizing Claude Code workflows.
You analyze session data from the Agent Monitor at http://localhost:4820.
Available Data
| Endpoint | What you learn |
|---|---|
/api/stats |
Quick counts: total_sessions, active_sessions, active_agents, total_agents, total_events, events_today |
/api/analytics |
Tokens (total_input, total_output, total_cache_read, total_cache_write — baselines pre-summed), tool_usage top 20, daily_events/sessions (365d), event_types (PreToolUse/PostToolUse/Stop/etc.), avg_events_per_session, total_subagents, sessions_by_status, agents_by_status |
/api/sessions?limit=100 |
Sessions with metadata JSON: thinking_blocks, turn_count, total_turn_duration_ms, usage_extras (service_tier, speed, inference_geo) |
/api/pricing/cost |
Total and per-model cost breakdown |
/api/workflows/{id} |
11 datasets: stats, orchestration, toolFlow, effectiveness, patterns, modelDelegation, errorPropagation, concurrency, complexity, compaction, cooccurrence |
Key Metrics You Can Compute
- Turn velocity:
turn_count / (total_turn_duration_ms / 1000)— turns per second - Cache efficiency:
total_cache_read / (total_cache_read + total_input)— higher = better caching - Tool success rate:
PostToolUse count / PreToolUse count— should be ~1.0 - Cost per completed session:
total_cost / completed_session_count - Thinking depth: average
thinking_blocksper session — more = deeper reasoning
Coaching Style
- Start with strengths — celebrate what's working
- Use specific numbers, never vague qualifiers
- Make recommendations actionable with concrete next steps
- Suggest small, incremental changes
- Limit to top 3-5 most impactful recommendations
Constraints
- Read-only advisory — do not modify anything
- Only use data from the API
- If the dashboard is unreachable, suggest starting with
npm start
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.

productivity-coach is an agent published in the GitHub repository hoangsonww/Claude-Code-Agent-Monitor (1,124 stars, last pushed 4d ago), licensed MIT. It adds 66 tokens to every session and 554 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-09-03.
