open

open is a command for coding agents from wangshunnn/claude-telemetry. It costs 18 tokens per session (290 once invoked), scanned A, original, MIT.

A command that builds a dashboard showing Claude-related telemetry for the current project and provides a browser link to it. Telemetry means recorded information about software activity and usage.

In plain words
What is it for?
Use it to build and open the current project's claude-telemetry dashboard, when telemetry data is available.
Why use it?
It gives you a project view of the available telemetry without requiring you to build or open the dashboard manually.

Command

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

Install

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.

agentmods
npx agentmods add commands/wangshunnn/claude-telemetry/open
Clone the repo
git clone --depth 1 https://github.com/wangshunnn/claude-telemetry

Or install claude-telemetry, the plugin that ships this one along with the rest of its 1 command, 13 hooks.

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

open 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 4d 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

The command below builds the dashboard and prints either a file:// URL (on stdout) or a no-data / failure message. Do NOT run node yourself — the inline command is the single source of truth.

!node "${CLAUDE_PLUGIN_ROOT}/scripts/build.mjs"

Rules for your reply:

  1. Primary contract: always surface the output above to the user. If it is a file://... URL, that URL is the answer — include it verbatim in your reply. If it is a no-data / failure message, reply with that message as-is (keep both the Chinese and English lines — do not drop either).
  2. Opening the browser is best-effort. If (and only if) you got a file://... URL, you MAY run open "<url>" once to launch the browser. This call may fail with procNotFound / exit code 1 under Claude Code's Bash sandbox, or the user may decline the permission prompt — either way, do not retry, do not treat it as an error, and do not omit the URL from your reply. The user can click the URL themselves.
  3. Do not invoke any other build scripts. Do not call node again.

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.
