 ## Configuration
 
-These are provided by the invoker's environment (TOOLS.md, AGENTS.md,
-or invocation context):
+Set these in your workspace context (TOOLS.md, AGENTS.md, or pass
+explicitly when invoking the skill):
 
-- **CLONE_DIR** — where to clone repos (e.g., `~/src/analysis/`)
-- **CLONE_HOST** — which machine to clone on (needs disk + git)
-- **GIT_REMOTE** — where convention repos are pushed (e.g., Gitea, GitHub)
-- **GIT_ORG** — organization/user for convention repos
-- **GIT_TOKEN_PATH** — path to auth token for pushing
+| Parameter | Description | Example |
+|-----------|-------------|----------|
+| `CLONE_DIR` | Directory to clone repos into | `~/src/analysis/` |
+| `CLONE_HOST` | Machine with disk + git for cloning | `forge`, `localhost` |
+| `GIT_REMOTE` | Where convention repos are pushed | `https://gitea.example.com` |
+| `GIT_ORG` | Org/user for convention repos | `myorg`, `username` |
+| `GIT_TOKEN_PATH` | Path to auth token for pushing | `~/.credentials/gitea-token` |
 
-If not explicitly provided, infer from workspace context.
+**Minimum required:** `CLONE_DIR` and `GIT_REMOTE`. If others are
+omitted:
+- `CLONE_HOST` defaults to localhost (current machine)
+- `GIT_ORG` defaults to the authenticated user
+- `GIT_TOKEN_PATH` uses default git credential helper
+
+**Example in TOOLS.md:**
+```markdown
+## Codebase Analysis
+- CLONE_DIR: ~/src/analysis/
+- CLONE_HOST: my-dev-server (ssh user@host)
+- GIT_REMOTE: https://github.com
+- GIT_ORG: my-patterns
+- GIT_TOKEN_PATH: ~/.credentials/github-token
+```
+
+If not explicitly provided, infer from workspace context (TOOLS.md,
+shell environment, or git remote configuration).
