# provider-adapter-author

Convert a target repo's provider-specific instruction file (CLAUDE.md, .cursor/rules, copilot-instructions.md, etc.) into a thin adapter over AGENTS.md.

## What it does

Detects a provider-specific AI instruction file in a target repo, diffs it against the repo's `AGENTS.md`, and rewrites it down to a minimal reference — an `@AGENTS.md`-style import for providers that support one, or a text pointer for those that don't — plus only genuinely provider-specific additions. Self-validates its own output with a bundled deterministic script (no LLM judgment, no separate audit skill) before finishing.

## Before you start

The target repo must already have an `AGENTS.md`. If it doesn't, run `agentsmd-author` first — this skill never creates or edits `AGENTS.md` itself.

## Usage

```
/provider-adapter-author
```

Provide the path to the provider-specific file to convert (and the target repo root, if not inferable). Can be invoked directly, or composed into by `agentsmd-author` when it detects an existing provider file with content overlapping AGENTS.md.

## Files

| File | Purpose |
|------|---------|
| `SKILL.md` | Skill instructions for agents |
| `references/sources.md` | Provenance record — the in-repo ADR precedent this skill's design is modeled on |
| `scripts/validate-adapter.sh` | Self-check gate: reference to AGENTS.md present, no excessive duplication, adapter stays thin |
| `scripts/README.md` | Directory documentation for `scripts/` |
| `tests/README.md` | (source-only) Bats test dependency and run instructions |
| `tests/validate-adapter.bats` | (source-only) Bats test suite for `scripts/validate-adapter.sh` |

Rows marked **(source-only)** exist in the authoring source (`.apm/skills/provider-adapter-author/`)
but are not present in an installed plugin: `scripts/sync-plugin-content.sh` strips
`<category>/<name>/tests` when it generates the flat mirror, because these are dev-time fixtures no
plugin host needs to discover (ADR-0017). Run them from a repo checkout, not from an install.
