Discovers and injects project-specific coding guidelines from .trellis/spec/ before implementation begins. Reads spec indexes, pre-development checklists, and shared thinking guides for the target package. Use when starting a new coding task, before writing any code, switching to a different package, or needing to refresh project conventions and standards.
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
Read the relevant development guidelines before starting your task. Execute these steps: 1. **Read current task artifacts**: - `prd.md` for requirements and acceptance criteria - `design.md` if present for technical design - `implement.md` if present for execution order and validation plan 2. **Discover packages and their spec layers**: ```bash python ./.trellis/scripts/get_context.py --mode packages ``` 3. **Identify which specs apply** to your task based on: - Which package you're modifying (e.g., `cli/`, `docs-site/`) - What type of work (backend, frontend, unit-test, docs, etc.) - Any spec/research paths referenced by the task artifacts 4. **Read the spec index** for each relevant module: ```bash cat .trellis/spec/<package>/<layer>/index.md ``` Follow the **"Pre-Development Checklist"** section in the index. 5. **Read the specific guideline files** listed in the Pre-Development Checklist that are relevant to your task. The index is NOT the goal — it points you to the actual guideline files (e.g., `error-handling.md`, `conventions.md`, `mock-strategies.md`). Read those files to understand the coding standards and patterns. …

How to install
mdr add fy-agent/fyagent/trellis-before-dev@sha256:02a88bae9ee5c8d5The line at the top of this page pins the label git:20260821.4c99eb1, 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.
