Use when a developer's LLM app is running but has NO traces yet and wants capture flowing in about a minute with no code changes — "instrument my app", "start capturing my LLM calls", "I have no traces, get me some", "turn on tracing for my agent". Detects the provider SDK, redirects it through the Orchestra gateway (capture on by default) via env vars, verifies a capture actually landed, then hands off to ingest-traces.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Instrument [`../ingest-traces/SKILL.md`](../ingest-traces/SKILL.md) and [`../capture-evidence/SKILL.md`](../capture-evidence/SKILL.md) assume traces already exist. This worker is the on-ramp before that: a running app, zero traces, and a developer who wants captures flowing **without editing app code**. One redirect, one test call, one verified capture — then hand off. **Say this up front:** "This takes about 5 minutes: ~1 minute to detect your SDK, ~2 minutes to sign in if you haven't, ~1 minute to redirect and verify a test call. No code changes, and nothing leaves your machine without your approval." ## Resolve CLI Prefer the installed `orchestra` binary. If it is unavailable inside a repo checkout, run through the package script: ```sh npm run build node dist/bin.js instrument --check --json ``` ## Safety Gates - **No app-code edits on this path.** The whole point is env-var redirection. If a codebase hardcodes a base URL so env vars cannot work, say so and offer the code-patch recipes in `skills/onboard/` as an explicitly separate, approval-gated step — do not silently edit. - **Redirecting traffic through the gateway is an external write of the …

How to install
mdr add understudylabs/orchestra-agent-tools/instrument@sha256:569b02a28c40b818The line at the top of this page pins the label git:20261027.533318e, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
