## What it does
This skill handles label and milestone CRUD (`label_read`/`label_write`, `milestone_read`/`milestone_write`) — listing repo or org labels, creating/editing/deleting a label, resolving a label name to the numeric ID required for any write, and listing/creating/updating/closing/deleting a milestone. It also owns label inference: mapping conversation context (bug report, feature request, urgency language) to this repo's `Kind/*`/`Priority/*`/`Status/*` taxonomy. It is a cross-cutting shared skill composed by `gitea-issues` and `gitea-prs`, which call into it for label/milestone resolution before their own `issue_write`/`pull_request_write` calls apply the resolved IDs.

## Composition
This is a cross-cutting shared skill. `gitea-issues` and `gitea-prs` both compose it whenever they need to apply a label or assign a milestone, rather than duplicating label/milestone logic: they call in for name/title → ID resolution, then their own `issue_write`/`pull_request_write` calls apply the resolved IDs. The split is deliberate — identity resolution lives here once, and the write that attaches an ID to a specific issue or PR lives with the skill that owns that object.
That relationship is documented here rather than in the skill description, which is preloaded into every session and carries routing information only: an agent reaches this skill because the user asked about labels or milestones, not because two other skills call it.

## Gotchas
- **Label writes take IDs, reads return names.** `label_read` is the only tool that returns full label objects (`id`, `name`, `color`, `description`). Issue/PR responses slim labels down to name strings. Before any label is applied to an issue or PR (in `gitea-issues`/`gitea-prs`), resolve names → IDs here via `label_read method: "list_repo_labels"` — never pass a name string where an ID is expected.
- **Milestones are referenced by ID everywhere, never by title.** `milestone_write` update/delete take `id`. The one place titles show up as the sole handle is the `pull_request_read` response (see next gotcha).
- **Milestone representation differs between issues and PRs.** `issue_read` returns `milestone: {id, title}` — an object. `pull_request_read` returns `milestone: "title string"` — title only, no ID. You cannot recover a milestone ID from a PR response directly; call `milestone_read method: "list"` and match by title instead.
- **Repo labels and org labels are separate pools, never mixed in one call.** `label_read`/`label_write` take either `owner`+`repo` (repo-scoped methods) or `org` (org-scoped methods) — passing both or neither for a given method is a caller error, not something the schema enforces for you. Repo and org labels can both apply to the same issue, but you list/create/edit them through different method values.
- **`milestone_write` accepts `"update"` and `"edit"` as the same operation.** Both method values map to the identical update call. Prefer `"update"` for consistency with `issue_write`/`pull_request_write`.
- **`exclusive` is documented as an org-labels-only flag — it isn't what enforces exclusivity here.** Gitea's docs scope the settable/server-enforced `exclusive` flag to org labels only, and the live `label_write` schema for `create_repo_label`/`edit_repo_label` doesn't document accepting it at all. This repo's `Kind/*`, `Priority/*`, `Status/*` groups still behave as one-label-per-scope, but that's a manually-enforced convention this skill implements client-side, not a guaranteed server behavior for repo labels: applying a new label within a scope (e.g. `Priority/High`) must replace any existing label in that same scope, not add alongside it, and nothing on the server enforces that for you. Label inference (see `references/label-inference.md`) must respect this — replace, don't stack.
- **Pagination is manual on every list call.** `label_read` and `milestone_read` both default to `per_page: 30`. Iterate `page: 1, 2, ...` until the result count is less than `per_page` — there is no cursor or auto-pagination.
- **Schema requiredness differs between the two tool families.** `milestone_read`/`milestone_write` have `owner` and `repo` as hard-required parameters (the call fails validation without them). `label_read`/`label_write` only hard-require `method` — `owner`/`repo`/`org` are functionally required per method but not schema-enforced, so passing none produces a runtime error from Gitea, not a client-side validation error.
- **Applying a label takes a numeric ID, but issue/PR responses slim labels down to name strings.** An issue's existing labels yield no IDs — resolve name → ID with `label_read`.
- **`pull_request_read` returns `milestone` as a bare title string** where `issue_read` returns `{id, title}` — recover the milestone's ID by listing milestones and matching the title.
- **`Kind/*`/`Priority/*`/`Status/*` exclusivity is a client-side convention.** `exclusive` is an org-labels-only flag, so applying a label in such a scope must replace the one already there, not stack on it.
## Step 1 — Resolve owner and repo

Before any tool call, extract `owner` and `repo` from the git remote (skip this if an orchestrating caller already passed them in):

The `*_org_label*` methods take `org`, not `owner`/`repo`. Pass that same `owner` as `org` — it is the org name whenever the owner is an organisation, and the remote URL does not say whether it is one. So let the call itself decide: a failure means the owner is a user account with no org label pool, which is an answer, not an error to report.

For full parameter detail and step-by-step call sequences, read `references/labels.md` (label operations) or `references/milestones.md` (milestone operations). For mapping conversation context to a label to apply, read `references/label-inference.md`.
Every list method paginates manually — `per_page` defaults to 30, so iterate `page: 1, 2, ...` until a page returns fewer results than `per_page`. A truncated list silently breaks name → ID resolution.
Applying resolved label IDs or a milestone ID to a specific issue or PR is out of scope here — that's `issue_write`/`pull_request_write` in the composing skill (`gitea-issues`/`gitea-prs`).
If the task is a label operation, read `references/labels.md`; if a milestone operation, read `references/milestones.md`. If the label to apply has to be derived from conversation context rather than named, read `references/label-inference.md`.

`exclusive` is an org-labels-only flag, this taxonomy plausibly lives at org scope too: for any
inferred name absent from the repo pool, also call `label_read method: "list_org_labels"` with
`org` set to the repo's `owner` before treating it as unresolved. A failure there means the owner
is a user account, not an organisation, so no org pool exists and the name is genuinely absent.

already has a different label applied on the target and a new one is inferred for that same
