+## Agent skills
+
+### Issue tracker
+
+Issues live in this repo's Gitea Issues (`git.arthurerlich.de`), driven via the `tea` CLI; relations are body conventions (`Part of #`, `Blocked by:`) since Gitea has no sub-issues. See `docs/agents/issue-tracker.md`.
+
+### Triage labels
+
+Default five-role vocabulary (`needs-triage`, `needs-info`, `ready-for-agent`, `ready-for-human`, `wontfix`), label strings equal to role names. See `docs/agents/triage-labels.md`.
+
+### Domain docs
+
+Single-context: one `GLOSSARY.md` + `docs/adr/` at the repo root. See `docs/agents/domain.md`.

+# Domain Docs
+
+How the engineering skills should consume this repo's domain documentation when exploring the codebase.
+
+## Before exploring, read these
+
+- **`GLOSSARY.md`** at the repo root, or
+- **`GLOSSARY-MAP.md`** at the repo root if it exists: it points at one `GLOSSARY.md` per context. Read each one relevant to the topic.
+- **`docs/adr/`**: read ADRs that touch the area you're about to work in. In multi-context repos, also check `src/<context>/docs/adr/` for context-scoped decisions.
+
+If any of these files don't exist, **proceed silently**. Don't flag their absence; don't suggest creating them upfront. The `/domain-modeling` skill (reached via `/grill-with-docs` and `/improve-codebase-architecture`) creates them lazily when terms or decisions actually get resolved.
+
+## File structure
+
+Single-context repo (most repos):
+
+```
+/
+├── GLOSSARY.md
+├── docs/adr/
+│   ├── 0001-event-sourced-orders.md
+│   └── 0002-postgres-for-write-model.md
+└── src/
+```
+
+Multi-context repo (presence of `GLOSSARY-MAP.md` at the root):
+
+```
+/
+├── GLOSSARY-MAP.md
+├── docs/adr/                          ← system-wide decisions
+└── src/
+    ├── ordering/
+    │   ├── GLOSSARY.md
+    │   └── docs/adr/                  ← context-specific decisions
+    └── billing/
+        ├── GLOSSARY.md
+        └── docs/adr/
+```
+
+## Use the glossary's vocabulary
+
+When your output names a domain concept (in an issue title, a refactor proposal, a hypothesis, a test name), use the term as defined in `GLOSSARY.md`. Don't drift to synonyms the glossary explicitly avoids.
+
+If the concept you need isn't in the glossary yet, that's a signal: either you're inventing language the project doesn't use (reconsider) or there's a real gap (note it for `/domain-modeling`).
+
+## Flag ADR conflicts
+
+If your output contradicts an existing ADR, surface it explicitly rather than silently overriding:
+
+> _Contradicts ADR-0007 (event-sourced orders), but worth reopening because…_

+# Issue tracker: Gitea (via tea CLI)
+
+Issues and specs for this repo live as Gitea issues on
+`git.arthurerlich.de/haylan/mattpocock-skills-opencode`. Use the `tea` CLI for all operations;
+the `gitea-tea` skill has command recipes. `tea` infers the repo from `git remote` inside this clone.
+
+**One-time human step (not done yet):** `tea logins add` for `https://git.arthurerlich.de`
+(token from the web UI: Settings → Applications). Until then, tracker operations fail.
+
+## Conventions
+
+- **Create an issue**: `tea issues create -t "<title>" --description-file -` (stdin for
+  multi-line bodies). Labels: `-L needs-triage,bug` (comma-separated; must exist — see Labels).
+- **Read an issue**: `tea issues <number> --comments`.
+- **List issues**: `tea issues list --state open -f index,title,state,labels,assignees`
+  (add `body,comments` to `--fields` when a skill needs full content).
+- **Comment**: `tea comments <number> "<body>"`.
+- **Apply / remove labels**: `tea issues edit <number> -L "<label>"` / `--remove-labels "<label>"`.
+- **Assign**: `tea issues edit <number> -a <username>`.
+- **Close**: comment the reason, then `tea issues close <number>`.
+
+Gitea has **no sub-issues and no native blocked-by links**. Relations are body conventions:
+
+- **Parent/child**: `Part of #<parent>` as the first line of the child body, plus a task list of
+  children in the parent body.
+- **Blocking**: `Blocked by: #<n>, #<n>` near the top of the child body. A ticket is unblocked
+  when every listed blocker is closed.
+
+### Labels
+
+The five triage labels plus `wayfinder:map` and `wayfinder:research|prototype|grilling|task` must
+exist before first use. After login, create missing ones with `tea labels create`; check with
+`tea labels list`.
+
+## Pull requests as a triage surface
+
+**PRs as a request surface: no.** _(Set to `yes` if this repo treats external PRs as feature
+requests; `triage` reads this flag.)_ Gitea shares one number space across issues and PRs: resolve
+a bare `#42` with `tea issues 42`, falling back to `tea prs 42`.
+
+## When a skill says "publish to the issue tracker"
+
+Create a Gitea issue as above.
+
+## When a skill says "fetch the relevant ticket"
+
+Read it with `tea issues <number> --comments`.
+
+## Wayfinding operations
+
+Used by `wayfinder`. The **map** is a single issue with **child** issues as tickets.
+
+- **Map**: issue labelled `wayfinder:map`, holding the Notes / Decisions-so-far / Fog body.
+- **Child ticket**: `Part of #<map>` first body line, listed in the map's task list. Labels:
+  `wayfinder:<type>` (`research`/`prototype`/`grilling`/`task`). Once claimed, assigned to the
+  driving dev.
+- **Blocking**: `Blocked by: #<n>` line (no native equivalent).
+- **Frontier query**: list the map's open children (`tea issues list --state open`), drop any
+  whose `Blocked by:` names an open issue or that has an assignee; first in map order wins.
+- **Claim**: `tea issues edit <n> -a <username>`, the session's first write.
+- **Resolve**: `tea comments <n> "<answer>"`, then `tea issues close <n>`, then append a context
+  pointer to the map's Decisions-so-far (edit the map body).

+# 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 "Label in our tracker" column to match whatever vocabulary you actually use.
