skill-telemetry

skill-telemetry is a skill for Claude Code, Codex from taosdata/agent-skills. It costs 35 tokens per session (498 once invoked), scanned A, original, MIT.

A telemetry reporter that sends a usage event when another skill is activated. Telemetry is data collected about software use.

In plain words
What is it for?
Use it as part of a skill system that tracks the skill name, version, author, and machine-related metadata when a skill runs.
Why use it?
It records skill-invocation metadata for usage analysis, while the supplied description says it does not collect user input, file contents, or secrets.

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

skill-telemetry 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 6d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/telemetry.ps1, scripts/telemetry.py), 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.

What it actually says

skill-telemetry

Client-side telemetry reporter. When any Skill is activated, this Skill sends a single invocation event to skill-telemetry-server for usage analytics.

Privacy: Only Skill metadata (name, version, author) and machine identifiers (OS, IP) are reported. No user input, file content, or secrets are collected. All data stays on the internal network.

When to Use

Triggered automatically by the ## Telemetry (MUST) section in every Skill. No user interaction required.

Input

Param Required Source Description
name Caller's frontmatter name Skill identifier
version Caller's metadata.version Skill version
author Caller's metadata.author Skill author

Agent Execution Rule

Agent MUST run the telemetry command below BEFORE executing the caller Skill's logic. Mandatory — must not be skipped. Failure is non-blocking but the attempt is required.

Replace {{SKILL_NAME}}, {{SKILL_VERSION}}, {{SKILL_AUTHOR}} with actual values from the caller Skill's frontmatter.

The agent MUST resolve the path to scripts/telemetry.py (or scripts/telemetry.ps1 on Windows) relative to this SKILL.md file. If the path cannot be resolved, set SKILL_TELEMETRY_SCRIPT to the absolute path. If both fail, skip telemetry silently.

Linux / macOS:

python3 "${SKILL_TELEMETRY_SCRIPT:-<resolve scripts/telemetry.py>}" "{{SKILL_NAME}}" "{{SKILL_VERSION}}" "{{SKILL_AUTHOR}}" 2>/dev/null &

Windows:

& "${env:SKILL_TELEMETRY_SCRIPT:-<resolve scripts/telemetry.ps1>}" '{{SKILL_NAME}}' '{{SKILL_VERSION}}' '{{SKILL_AUTHOR}}'
Files

What ships with it

3 files 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.
