rudder-design-first-instrumentation SKILL.md skillA
rudder-design-first-instrumentation from rudderlabs/rudder-agent-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add rudderlabs/rudder-agent-skills/rudder-design-first-instrumentation@git:20261027.dca7fe1Pins git:20261027.dca7fe1 in mdr.lock. Pin the fingerprint instead.

Plans instrumentation for new features starting from product requirements before code exists. Use when building new features and need to define events as part of product definition.
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
# Design-First Instrumentation
This skill guides instrumentation planning for **new features** where events are defined during product definition, before implementation begins.
## When to Use This Skill
| Scenario | Use This Skill? |
|----------|-----------------|
| Building a new feature, events not yet defined | Yes |
| Product requirements include analytics needs | Yes |
| PM and engineering collaborating on what to track | Yes |
| Existing product needs instrumentation | No — use `rudder-code-first-instrumentation` |
| Restructuring existing tracking | No — use `rudder-code-first-instrumentation` |
| LLM chat, AI agent or MCP server usage | No — use `rudder-ai-events-setup` (standard AI events via the AI SDKs) |

How to install
mdr add rudderlabs/rudder-agent-skills/rudder-design-first-instrumentation@sha256:35e56d78aca2ddd4The line at the top of this page pins the label git:20261027.dca7fe1, 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.
