cf-tdd SKILL.md skillA
cf-tdd from dinhanhthi/coding-friend is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add dinhanhthi/coding-friend/cf-tdd@git:20260926.ef3f61ePins git:20260926.ef3f61e in mdr.lock. Pin the fingerprint instead.

Gate before writing production code — direct implementation by default, TDD (RED→GREEN→REFACTOR) with `--add-tests` or config `tdd: true`. TRIGGER — any new feature, implementation, or refactor: "implement this", "build this feature", "create a function", "add a new endpoint", "write the implementation", "refactor this", "write a test", "add tests", "create a component", "implement the API", "add a route"; also when planning shifts into writing code — load this first. SKIP — docs-only changes…
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
# Implementation Workflow
## Custom Guide
```!
bash "${PLUGIN_ROOT}/lib/load-custom-guide.sh" cf-tdd
```
If the block above printed anything, apply only the `## Before`, `## Rules`, and `## After` sections; if it shows the raw command instead of output, re-run that exact `load-custom-guide.sh` fence now.
## Mode Detection
Determine the implementation mode BEFORE doing anything else:
1. Check if the user's invocation or task description contains `--add-tests`
2. Check if `.coding-friend/config.json` exists and has `"tdd": true`
3. Check if the user's invocation or task description contains `--auto` (orthogonal to mode — autopilot can combine with both Direct and TDD mode).
**Result:**
- `--add-tests` present OR `tdd: true` in config → **TDD mode**. Show: `> TDD mode enabled — RED → GREEN → REFACTOR`. → TDD mode: Read `${PLUGIN_ROOT}/skills/cf-tdd/modes/tdd-mode.md` now and follow RED→GREEN→REFACTOR.
- Neither → **Direct mode** (default). Show: `> Direct mode — implementing without new tests`
- Additionally, if `--auto` is present → **Autopilot active**. Show: `> 🤖 Autopilot enabled — will auto-review, auto-fix Critical+Important, and auto-commit after implementation.`

How to install
mdr add dinhanhthi/coding-friend/cf-tdd@sha256:ac32ca68f2db1e7dThe line at the top of this page pins the label git:20260926.ef3f61e, 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.
