trellis-update-spec SKILL.md skillA

trellis-update-spec from fy-agent/fyagent is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add fy-agent/fyagent/trellis-update-spec@git:20260728.8eb278f

Pins git:20260728.8eb278f in mdr.lock. Pin the fingerprint instead.

License
a license file GitHub does not identify

Captures executable contracts and coding conventions into .trellis/spec/ documents. Use when learning something valuable from debugging, implementing, or discussion that should be preserved for future sessions.

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

# Update Code-Spec - Capture Executable Contracts

When you learn something valuable (from debugging, implementing, or discussion), use this to update the relevant code-spec documents.

**Timing**: After completing a task, fixing a bug, or discovering a new pattern

---

## Code-Spec First Rule (CRITICAL)

In this project, "spec" for implementation work means **code-spec**:
- Executable contracts (not principle-only text)
- Concrete signatures, payload fields, env keys, and boundary behavior
- Testable validation/error behavior

If the change touches infra or cross-layer contracts, code-spec depth is mandatory.

### Mandatory Triggers

Apply code-spec depth when the change includes any of:
- New/changed command or API signature
- Cross-layer request/response contract change
- Database schema/migration change
- Infra integration (storage, queue, cache, secrets, env wiring)

### Mandatory Output (7 Sections)

For triggered tasks, include all sections below:
1. Scope / Trigger
2. Signatures (command/API/DB)
3. Contracts (request/response/env)
4. Validation & Error Matrix
5. Good/Base/Bad Cases
6. Tests Required (with assertion points)
7. Wrong vs Correct (at least one pair)

How to install

The exact contents, by fingerprint
mdr add fy-agent/fyagent/trellis-update-spec@sha256:003ce08a3404aeb5

The line at the top of this page pins the label git:20260728.8eb278f, 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.
