+# docs/
+
+Plugin documentation. Not read automatically by Claude Code or GitHub Copilot CLI — reference specific files from skill bodies or agent prompts as needed.
+
+## research/
+
+Upstream reference material gathered during skill authoring. Not shipped with the plugin — used at development time only.
+
+| Path | Purpose |
+|------|---------|
+| `research/docs/vale/` | Vale documentation (vale.sh), gathered while authoring `vale-config`/`vale-run` — see below |
+
+### research/docs/vale/
+
+| File | Covers |
+|------|--------|
+| `overview.md` | What Vale is; the style/rule/check configuration model; the built-in `Vale` style's four rules; styles directory layout |
+| `installation.md` | Installing Vale via OS package managers (Homebrew, Snap, Chocolatey) and Docker |
+| `configuration.md` | `.vale.ini` structure — global, `[formats]`, and per-glob sections |
+| `cli-reference.md` | Core invocation and key subcommands/flags (`vale sync`, `vale ls-config`, etc.) |
+| `examples.md` | Walkthroughs — project initialization, typical `.vale.ini` configs |
+| `troubleshooting.md` | Suppressing false positives via inline markup (format-specific `vale off`/`vale on` syntax, spelling ignore lists) |
+| `sources.md` | Provenance record for this directory — source URL, description, and which files above were extracted from it |
+
+Each file's frontmatter carries a `source_keys` entry keyed to the same provenance record. The plugin-level provenance file, `plugins/lint/sources.md`, cross-references this directory from the `context7-websites-vale-sh` entry and lists the agents/skills whose content drew on it.
+
+`vale-config` and `vale-run` are the skills that consume this research — read the relevant file here before changing either skill's Vale-facing behavior.
