Otel Java is an agent skill from ollygarden/opentelemetry-agent-skills. OpenTelemetry in Java — Javaagent zero-code instrumentation, Spring Boot Starter, manual autoconfigure SDK, declarative YAML configuration, BOM dependency management, sensitive-data capture and redaction (url.query, headers, request parameters, SQL sanitization). Use when adding, reviewing, or configuring OpenTelemetry in a Java service. Triggers on "setup otel in java", "java telemetry", "javaagent", "Spring Boot otel", "GlobalOpenTelemetry", "AutoConfiguredOpenTelemetrySdk", "TracerProvider java", "url.query…
Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including reference files (for example `references/declarative-setup.md` and `references/sensitive-data-capture.md`).
It sits in DevOps & Cloud, covering Observability and Backend development. It works with OpenTelemetry, Java, Spring Boot and SQL. The repository describes itself as: Vendor-neutral OpenTelemetry skills for AI coding agents like Claude Code, Cursor, and Codex, grounded in upstream sources. The licence is Apache-2.0.
2 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 7cf0de9. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Shell commands in SKILL.md call:
ghFrom the folder's file list and the shell code blocks in SKILL.md.
Hosts in commands or code, which the agent is likely to contact:
explorer.opentelemetry.ioraw.githubusercontent.comopentelemetry.ioFrom URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Otel Java loads about 1.4k tokens when it runs, and up to ~5.1k if it reads all its reference files. Until then it costs about 150 tokens; SKILL.md has 387 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

For "what does the agent produce for library X" — which spans, attributes, metrics, or config knobs — use the OpenTelemetry Ecosystem Explorer, which fully maps the Java agent and exposes an agent-friendly surface (Markdown indexes and resolved JSON, no scraping). Do not answer from model memory.
Navigation:
WebFetch https://explorer.opentelemetry.io/agent/javaagent/index.md — table mapping display
name → id → the instrumentation's JSON data URL (the URL embeds the content <hash>).WebFetch that JSON URL — one self-contained record (a few KB): resolved configurations,
telemetry (spans with span_kind + typed attributes, and metrics),
javaagent_target_versions, semantic_conventions, and scope.Version-specific or "what changed between releases":
https://explorer.opentelemetry.io/agent/javaagent/versions.md lists versions and marks the latest;
https://explorer.opentelemetry.io/data/javaagent/versions/<version>-index.json gives the
id→hash map for a version — a differing hash for the same id across two versions means that
instrumentation changed. Schema:
https://explorer.opentelemetry.io/schemas/javaagent-instrumentation.schema.json; use
/llms.txt for the agent-oriented index and /llms-full.txt for the full documentation.
Prefer this Explorer data over the raw ecosystem-registry YAML on GitHub: the Explorer applies
upstream metadata corrections that the raw registry does not.

OpenTelemetry in Java — Javaagent zero-code instrumentation, Spring Boot Starter, manual autoconfigure SDK, declarative YAML configuration, BOM dependency management, sensitive-data capture and…. Otel Java is an agent skill from ollygarden/opentelemetry-agent-skills.query, headers, request parameters, SQL sanitization).
Otel Java fits situations like: configuring OpenTelemetry in a Java service; setup otel in java; spring Boot otel; globalOpenTelemetry.
Run `npx skills add ollygarden/opentelemetry-agent-skills --skill otel-java -a claude-code`. Or copy the skill folder (skills/otel-java in ollygarden/opentelemetry-agent-skills) into .claude/skills/otel-java in your project. Claude Code loads it when a task matches its description.
Run `npx skills add ollygarden/opentelemetry-agent-skills --skill otel-java -a codex`. Or copy the skill folder (skills/otel-java in ollygarden/opentelemetry-agent-skills) into .agents/skills/otel-java in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add ollygarden/opentelemetry-agent-skills --skill otel-java -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/otel-java, .gemini/skills/otel-java, .github/skills/otel-java and .opencode/skills/otel-java in your project.
Going by SKILL.md and its folder, Otel Java needs the command-line tools its instructions call (gh).
SKILL.md names 3 domains. In commands or code: explorer.opentelemetry.io, raw.githubusercontent.com and opentelemetry.io; the agent is likely to contact these when it follows the instructions. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Otel Java is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.4k tokens (SKILL.md is roughly 5.5k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 3.7k tokens, read only when the agent opens those files.
Skills that share tags, products or a category with Otel Java: AI Observability (rrezartprebreza/spring-boot-skills, 298 stars), Production Observability (rrezartprebreza/spring-boot-skills, 298 stars), Production Observability (rrezartprebreza/spring-boot-skills, 298 stars) and Spring Boot Observability (HoangNguyen0403/agent-skills-standard, 571 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
