Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

Implement Feature
Implements a feature from its specification using the Forja (Dev) agent.
When to Use This Skill
- A feature spec has been approved and is ready for implementation
- You need architecture design, code, and tests for a defined feature
- Translating product requirements into working software
What This Skill Does
- Runs the SIGN IN checklist and verifies the spec handoff
- Designs architecture (creates ADR if needed)
- Defines interfaces/contracts, then implements in
src/ - Writes tests in
tests/(unit + integration) - Runs the Implementation Complete checklist (TIME OUT 1)
- Runs the Pre-Delivery checklist (TIME OUT 2)
- Prepares structured handoff to QA agent
- Runs the SIGN OUT checklist
How to Use
Basic Usage
/implement-feature webhook-event-systemWith Spec Reference
/implement-feature docs/specs/webhook-event-system.mdExample
User: /implement-feature user-authentication
Output:
- Implementation in
src/with all acceptance criteria met - Tests in
tests/covering critical paths - ADR if significant architecture decisions were made
- Handoff notes for QA: files changed, how to test, known limitations
Tips
- Ensure the feature spec exists before running this skill
- The agent creates an ADR for any significant architecture decisions
- Two TIME OUT checkpoints ensure both correctness and delivery cleanliness
