opentelemetry-agent-skills: Instructions file for Claude Code

AGENTS.md

opentelemetry-agent-skills AGENTS.md is an instructions file for Claude Code, Codex, OpenCode from ollygarden/opentelemetry-agent-skills. It costs 1,869 tokens per session, scanned A, original, Apache-2.0.

Repository instructions for maintaining a catalogue of OpenTelemetry skills, which help coding agents work with a system for collecting traces, metrics, and logs.

In plain words
What is it for?
Use them when adding, removing, renaming, or changing skills and their triggers, or when running the repository's validation workflow.
Why use it?
They define how to keep skill content, source links, registrations, and local checks correct as OpenTelemetry changes.

Written for Claude Code and Codex and OpenCode: Claude Code plugin machinery, but also the file is AGENTS.md. Also seen: mentions AGENTS.md.

This is ollygarden/opentelemetry-agent-skills's own configuration. It tells Claude Code, Codex and OpenCode how to work on opentelemetry-agent-skills itself, so it is not a mod to install elsewhere.

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

opentelemetry-agent-skills AGENTS.md 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 10d 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.

AGENTS.md

This file provides guidance to AI coding agents when working with code in this repository.

What this repository is

A catalog of Agent Skills (per the agentskills.io spec) for OpenTelemetry, published by OllyGarden. The skills are non-opinionated and vendor-neutral by design — there are many valid ways to use OpenTelemetry, so prescribing conventions is out of scope. They exist to give an agent token-efficient, agent-friendly retrieval: small fetch tables, lookup indexes, and scripts that point at upstream sources of truth instead of copying docs into context, so answers stay current as OpenTelemetry evolves.

Most changes are to Markdown and YAML files that AI agents consume. The exception is tools/otel-agent-tools/, a Go module that generates and validates some of the bundled reference data (see below). "Correctness" means a skill is well-scoped, accurate, points at the maintained source of truth, and is registered in all the right places.

Preferred workflow

For any change that adds, renames, moves, or removes a skill, or that alters what a skill triggers on or recommends, follow docs/preferred-workflow.md. Typo and prose fixes go straight to a PR — unless they touch SKILL.md frontmatter, since a description: edit changes when the skill activates.

Running the gates locally

The two skill gates are scripts in bin/. Both resolve the repository root themselves, so any path spelling works from any working directory — the ./ form below assumes you are at the root:

./bin/validate-skill.sh            # spec conformance + house rules; a path checks one skill
./bin/check-skill-inventory.py     # skills/, marketplace.json, and README in sync

CI enforces one further check that is not a bin/ script: the Link Check workflow. Reproduce it locally with the lychee command in docs/preferred-workflow.md.

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.
