 - If the correct CLI is missing, tell the user to install it or add it to `PATH`.
 - Do not use the wrong CLI as a fallback.
 
-## Open Questions To Fill In Later
+## Derived Preferences (auto-detected at runtime)
 
-- Known personal Gitea hosts.
+- Canonical forge remote: prefer `forge`, then default remote, then `origin`.
-- GitHub usernames or organizations.
+- Forge CLI: determined from remote URL (GitHub → `gh`, Gitea → `tea`).
-- Preferred PR title/body format.
+- Known personal Gitea hosts and GitHub usernames/orgs are collected from the remote URL and git CLI at time of use — no hardcoded list.
-- Preferred issue labels and milestones.
+
-- Release naming and tagging conventions.
+## Issue Labels
+
+See `triage-labels.md` in this directory for the canonical-to-actual label mapping.
+
+## PR Conventions
+
+- PR titles follow Conventional Commits: `type(scope): description`.
+  - Common types: `feat`, `fix`, `refactor`, `docs`, `chore`, `test`, `style`.
+- PR body is freeform but should summarise the change and any breaking or noteworthy details.
+
+## Release Conventions
+
+- Tags follow semver: `v{major}.{minor}.{patch}` (e.g. `v1.2.3`).
+- Releases are created from the tag with auto-generated or manually curated notes.

+# Triage Labels
+
+The skills speak in terms of five canonical triage roles. This file maps those roles to the actual label strings used in this repo's issue tracker.
+
+| Label in mattpocock/skills | Label in our tracker | Meaning                                  |
+| -------------------------- | -------------------- | ---------------------------------------- |
+| `needs-triage`             | `needs-triage`       | Maintainer needs to evaluate this issue  |
+| `needs-info`               | `needs-info`         | Waiting on reporter for more information |
+| `ready-for-agent`          | `ready-for-agent`    | Fully specified, ready for an AFK agent  |
+| `ready-for-human`          | `ready-for-human`    | Requires human implementation            |
+| `wontfix`                  | `wontfix`            | Will not be actioned                     |
+
+When a skill mentions a role (e.g. "apply the AFK-ready triage label"), use the corresponding label string from this table.
+
+Edit the right-hand column to match whatever vocabulary you actually use.
