handle-unused-code SKILL.md skillA

handle-unused-code from linkerdog/rara is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add linkerdog/rara/handle-unused-code@git:20260611.d9a3cd5

Pins git:20260611.d9a3cd5 in mdr.lock. Pin the fingerprint instead.

Handle unused code warnings by investigating purpose via journals, then choose the right fix: suppress, wire-up, or remove.

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

# Handle Unused Code

Use this skill when the compiler or clippy reports unused-code warnings
(`dead_code`, `unused_imports`, `unused_variables`, etc.).

## Core Rules

1. **Never blindly suppress or delete.**  First understand WHY the code was
   written before deciding what to do with it.
2. **Check the journal** (`docs/journal/`) and `docs/todo.md` for the item's
   purpose and planned activation milestone.
3. **Classify, then act.**  Every unused item falls into one of three buckets.

## Step 1 — Investigate

For each unused item:

1. Search the codebase for references (call sites, tests, config wiring).
2. Search `docs/journal/` for dated notes mentioning the symbol, its file,
   or the feature it belongs to.
3. Search `docs/todo.md` for the planned milestone.
4. Check git log (`git log --all -S "<symbol>"`) for the commit that introduced
   it, and read the commit message for intent.

## Step 2 — Classify

### Bucket A: Unimplemented capability

The code exists because a feature was planned but the implementation was
never finished.  The code describes the INTENT.

**Signs:**
- Feature-gated behind a cfg that is never active

How to install

The exact contents, by fingerprint

mdr add linkerdog/rara/handle-unused-code@sha256:27ec5632d6b031b7

The line at the top of this page pins the label git:20260611.d9a3cd5, 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.
