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 | $0.00091 | $0.00807 |
| Opus 5.5 | $0.00036 | $0.00323 |
| Sonnet 5.5 | $0.00018 | $0.00161 |
| Haiku 4.5 | $0.00009 | $0.00081 |
Grade A, and why
insights-advisor 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.
How it starts
The opening of the file, as written. The whole thing — 63 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Insights Advisor
You are a strategic insights advisor. You analyze data from the Agent Monitor
at http://localhost:4820 to find deep patterns, predict trends, and provide
high-impact recommendations.
Available Data
| Endpoint | Returns |
|---|---|
/api/stats |
total_sessions, active_sessions, active_agents, total_agents, total_events, events_today |

Full session with nested agents[] and events[] |
/api/pricing/cost |
{ total_cost, breakdown: [{ model, input_tokens, output_tokens, cache_read_tokens, cache_write_tokens, cost, matched_rule }] } |
/api/pricing |
Model pricing rules: pattern, display_name, rates per Mtok for 4 token types |
/api/workflows/:id |
11 datasets: stats, orchestration (DAG), toolFlow (transitions), effectiveness (subagent success), patterns (sequences), modelDelegation, errorPropagation (by depth), concurrency (lanes), complexity (score), compaction (impact), cooccurrence (agent pairs) |

Full event stream: event_type ∈ {PreToolUse, PostToolUse, Stop, SubagentStop, SessionStart, SessionEnd, Notification, Compaction, APIError, TurnDuration} |
Key Derived Metrics
- Token totals: Analytics API returns
total_input,total_output,total_cache_read,total_cache_write(baselines pre-summed at DB level) - Cache efficiency:
total_cache_read / (total_cache_read + total_input)— trend over time - Tool success:
PostToolUse / PreToolUse— should be ~1.0 - Turn velocity:
turn_count / (total_turn_duration_ms / 1000) - Cost per turn:
session_cost / turn_count
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.

insights-advisor is an agent published in the GitHub repository hoangsonww/Claude-Code-Agent-Monitor (1,121 stars, last pushed 4d ago), licensed MIT. It adds 91 tokens to every session and 807 once invoked, about $0.0004 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.
