Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

observe 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.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/cli.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 155 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/observe

Agents Observe dashboard and server management.

Usage

  • /observe view — Open the current session in the dashboard
  • /observe stats — Open the current session's stats modal in the dashboard
  • /observe — Open the dashboard URL
  • /observe status — Show server health and config details
  • /observe start — Start the server
  • /observe stop — Stop the server
  • /observe restart — Restart the server
  • /observe logs-server — Show recent Docker container logs
  • /observe logs-cli — Tail the local cli.log file
  • /observe logs-mcp — Tail the local mcp.log file
  • /observe debug — Diagnose server issues (health, docker logs, mcp.log, cli.log)

Instructions

All commands are invoked via the wrapper at scripts/cli.sh, which resolves the path to observe_cli.mjs relative to this skill's install location. Do not reach outside the skill dir with ../ paths — the agentskills spec disallows it and it breaks portability across agents.

The subcommand is in $ARGUMENTS. If empty, default to showing the dashboard URL.

/observe view

Opens the current session in the dashboard.

  1. Run health to get the dashboard origin:
    scripts/cli.sh health
    
  2. From the output, take the Dashboard: URL (e.g. http://localhost:4981). If exit code 1, the server isn't running — tell the user to run /observe start and stop here.
  3. Construct the session URL: <dashboard>/#/_/${CLAUDE_SESSION_ID} (the _ is the project placeholder; the dashboard resolves the real project from the session id).
  4. Open it in the user's default browser using the platform-appropriate command — open <url> on macOS, xdg-open <url> on Linux, start <url> on Windows. Pick based on the Platform: line in your environment context.
  5. Also print the URL in your response so the user can re-open it if needed.

/observe stats

Opens the current session's stats modal in the dashboard, using a deep-link URL.

  1. Run health to get the dashboard origin:
    scripts/cli.sh health
    
  2. From the output, take the Dashboard: URL (e.g. http://localhost:4981). If exit code 1, the server isn't running — tell the user to run /observe start and stop here.
  3. Construct the deep link: <dashboard>/#/_/${CLAUDE_SESSION_ID}:session.stats
  4. Open it in the user's default browser using the platform-appropriate command — open <url> on macOS, xdg-open <url> on Linux, start <url> on Windows. Pick based on the Platform: line in your environment context.
  5. Also print the URL in your response so the user can re-open it if needed.

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

observe is a skill published in the GitHub repository simple10/agents-observe (666 stars, last pushed today), licensed MIT. It adds 8 tokens to every session and 1,314 once invoked, about $0.0000 per session on Opus 5. A static security scan graded it A with 0 findings.
