# gitea-labels-milestones
Read and write Gitea labels and milestones, and resolve label/milestone identity for the skills that apply them to issues and PRs.
## 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.
## Usage
```
/gitea-labels-milestones
```
Describe the label or milestone task: list labels, resolve a name to an ID, create/edit/delete a label, or list/create/update/close/delete a milestone. For applying already-resolved labels or a milestone to a specific issue or PR, use `gitea-issues` or `gitea-prs` instead.

name: gitea-labels-milestones
description: >
Use when reading or writing Gitea labels or milestones — listing repo/org labels, creating,
editing, or deleting a label, resolving label names to the numeric IDs required for applying
them to an issue or PR, or listing, creating, updating, closing, or deleting a milestone. This is
a cross-cutting shared skill: `gitea-issues` and `gitea-prs` both compose it whenever they need to
apply labels or assign a milestone, rather than duplicating label/milestone logic. Also use for
label inference — mapping a bug report, feature request, or urgency signal in conversation
context to the repo's `Kind/*`/`Priority/*`/`Status/*` label taxonomy. Do not use for applying
already-resolved label IDs or milestone IDs to a specific issue or PR — that write goes through
`issue_write`/`pull_request_write` in `gitea-issues`/`gitea-prs`, not here.
compatibility: Requires Gitea MCP server configured with write:issue and write:repository token scopes.

## 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`.
- **A `/` in a label name plus `exclusive: true` means mutual exclusivity, not just a naming convention.** This repo's `Kind/*`, `Priority/*`, `Status/*` labels follow Gitea's native scoped-label feature: applying a new label within a scope (e.g. `Priority/High`) is expected to replace any existing label in that same scope, not add alongside it. 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.
## Dispatch
| Task | Tool | method |
|---|---|---|
| List repo labels | `label_read` | `"list_repo_labels"` |
| Get one repo label by ID | `label_read` | `"get_repo_label"` |
| List org labels | `label_read` | `"list_org_labels"` |
| Create a repo/org label | `label_write` | `"create_repo_label"` / `"create_org_label"` |
| Edit a repo/org label | `label_write` | `"edit_repo_label"` / `"edit_org_label"` |
| Delete a repo/org label | `label_write` | `"delete_repo_label"` / `"delete_org_label"` |
| List milestones | `milestone_read` | `"list"` |
| Get one milestone by ID | `milestone_read` | `"get"` |
| Create a milestone | `milestone_write` | `"create"` |
| Update / close a milestone | `milestone_write` | `"update"` |
| Delete a milestone | `milestone_write` | `"delete"` |
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`.
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`).

# Label inference guide
Maps context-pattern signals from conversation content (an issue being drafted, a bug report, a PR
description) to this repo's `Kind/*` / `Priority/*` / `Status/*` label taxonomy. Used by
`gitea-issues` and `gitea-prs` before creating or updating an issue/PR, and directly when the user
asks to label something without naming exact labels.
## Scoped labels are mutually exclusive — replace, don't stack
Each of `Kind/*`, `Priority/*`, `Status/*` is a Gitea scoped-label group (the `/` delimiter plus
`exclusive: true` on the label). Applying a new label within a scope is expected to replace any
existing label in that same scope on the target issue/PR, not add alongside it. When inference
selects a `Priority/High` label and the issue already carries `Priority/Medium`, the write should
result in only `Priority/High` remaining — use `replace_labels` scoped to that group's labels, or at
minimum remove the superseded label before adding the new one. Never leave two labels from the same
scope applied at once.
## Signal → label mapping
**`Kind/*`** (what kind of work this is):
| Signal in context | Label |
|---|---|
| Bug report, error, crash, unexpected behavior, "broken", "doesn't work" | `Kind/Bug` |
| New capability, "add support for", net-new functionality | `Kind/Feature` |
| Improvement to existing behavior, "make X better", refactor with behavior change | `Kind/Enhancement` |
| Docs-only change, README/comment/guide updates | `Kind/Documentation` |
| Vulnerability, credential exposure, injection risk, auth bypass | `Kind/Security` |
**`Priority/*`** (urgency):
| Signal in context | Label |
|---|---|
| "blocking", "critical", "urgent", production-down | `Priority/Critical` |
| "soon", "high priority", "should do this sprint" | `Priority/High` |
| No urgency signal present | `Priority/Medium` (default) |
**`Status/*`** (workflow state):
| Signal in context | Label |
|---|---|
| Explicit statement that the work is blocked on something else | `Status/Blocked` |
## Procedure
1. Read the conversation context (issue/PR title, body, or the triggering discussion) for the
signals above.
2. Call `label_read method: "list_repo_labels"` (see `references/labels.md`) to get the current
label set with IDs — inference must never guess an ID, only a name, then resolve it.
3. Match inferred label names against the resolved list (case-insensitive). If a scope group
already has a different label applied on the target and a new one is inferred for that same
scope, plan to replace rather than add (see above).
4. **Low-confidence inference omits the label.** If no signal confidently maps to a `Kind/*` value,
do not guess — omit `Kind/*` entirely rather than default to one. `Priority/Medium` is the one
exception: it's the explicit default when no urgency signal is present, not a guess.
5. Hand the resolved IDs (plus which scopes to replace) to the caller's `issue_write`/
`pull_request_write` call — this skill does not apply labels to an issue or PR itself.

# Label operations
Execution detail for `label_read` and `label_write`. Both tools operate on either **repo-scoped**
or **org-scoped** labels — never both in one call. Pick the method family (`*_repo_label*` vs.
`*_org_label*`) that matches the target, and pass `owner`+`repo` or `org` accordingly.
## Verified live schemas
`label_read` — required: `method`.
| Param | Type | Notes |
|---|---|---|
| `method` | string (enum) | `"list_repo_labels"` \| `"get_repo_label"` \| `"list_org_labels"` |
| `owner` | string | for repo methods |
| `repo` | string | for repo methods |
| `org` | string | for org methods |
| `id` | number | label ID, required for `"get_repo_label"` |
| `page` | number | default `1` |
| `per_page` | number | default `30` |
`label_write` — required: `method`.
| Param | Type | Notes |
|---|---|---|
| `method` | string (enum) | `"create_repo_label"` \| `"edit_repo_label"` \| `"delete_repo_label"` \| `"create_org_label"` \| `"edit_org_label"` \| `"delete_org_label"` |
| `owner` | string | for repo methods |
| `repo` | string | for repo methods |
| `org` | string | for org methods |
| `id` | number | for edit/delete |
| `name` | string | required for create |
| `color` | string | hex `#RRGGBB`, required for create |
| `description` | string | optional |
| `exclusive` | boolean | org labels only |
| `is_archived` | boolean | repo labels only |
Note: unlike `milestone_read`/`milestone_write`, `owner`/`repo`/`org` are **not** schema-required on
either label tool — only `method` is. Passing none for a repo/org method still fails, just as a
runtime error from Gitea rather than a client-side validation error.
## List repo labels
```
label_read method: "list_repo_labels" owner: <owner> repo: <repo> per_page: 50
```
Paginate (`page: 1, 2, ...`) until the returned count is less than `per_page`. This is the only way
to build a complete name → ID map — there is no lookup-by-name endpoint.
## Get one label
```
label_read method: "get_repo_label" owner: <owner> repo: <repo> id: <id>
```
## Resolve a name to an ID
There is no direct name lookup. List all repo labels (paginating if needed), scan for a
case-insensitive name match, and extract `id`. This is the required first step before any label
application on an issue or PR — the actual `add_labels`/`replace_labels`/`remove_label` call lives
in `gitea-issues`/`gitea-prs` via `issue_write`/`pull_request_write`, which take numeric IDs only.
## Create a label
```
label_write method: "create_repo_label"
owner: <owner> repo: <repo>
name: "Kind/Bug"
color: "#d73a4a"
description: "Confirmed bug"
```
For an org label, use `method: "create_org_label"` with `org:` instead of `owner`/`repo`, and
`exclusive: true` if the label belongs to a mutually-exclusive scope group.
## Edit a label
```
label_write method: "edit_repo_label" owner: <owner> repo: <repo> id: <id> color: "#ff0000"
```
Only pass the fields being changed — `id` plus any of `name`/`color`/`description`/`is_archived`.
## Delete a label
```
label_write method: "delete_repo_label" owner: <owner> repo: <repo> id: <id>
```
Deleting a label does not remove it from historical issue/PR timeline events — it disappears only
from current label lists.

# Milestone operations
Execution detail for `milestone_read` and `milestone_write`. Milestones are always repo-scoped —
there is no org-level milestone concept, unlike labels.
## Verified live schemas
`milestone_read` — required: `method`, `owner`, `repo`.
| Param | Type | Notes |
|---|---|---|
| `method` | string (enum) | `"get"` \| `"list"` |
| `owner` | string | required |
| `repo` | string | required |
| `id` | number | milestone ID, required for `"get"` |
| `name` | string | title filter, for `"list"` |
| `state` | string | default `"all"` — conventional values `"open"`/`"closed"`/`"all"`, but **not enforced by an enum in the live schema** (plain string). Any other value is passed through to Gitea rather than rejected client-side. |
| `page` | number | default `1` |
| `per_page` | number | default `30` |
`milestone_write` — required: `method`, `owner`, `repo`.
| Param | Type | Notes |
|---|---|---|
| `method` | string (enum) | `"create"` \| `"update"` \| `"edit"` \| `"delete"` — `"update"`/`"edit"` are aliases for the same operation; prefer `"update"` |
| `owner` | string | required |
| `repo` | string | required |
| `id` | number | required for update/delete |
| `title` | string | required for create |
| `description` | string | optional |
| `due_on` | string | due date — the live tool schema only describes this as an opaque "due date" string with no enforced format; ISO 8601 (e.g. `"2025-03-01T00:00:00Z"`) is the conventional value Gitea's REST API accepts, not something confirmed by the live MCP schema itself |
| `state` | string (enum) | `"open"` \| `"closed"` — **this one is schema-enforced**, unlike `milestone_read`'s `state` |
Note: unlike `label_read`/`label_write`, both milestone tools hard-require `owner` and `repo` at the
schema level — there's no scope variant to omit them for.
## List milestones
```
milestone_read method: "list" owner: <owner> repo: <repo> state: "open"
```
Report each as: id, title, state, due date, open/closed issue counts.
## Get one milestone
```
milestone_read method: "get" owner: <owner> repo: <repo> id: <id>
```
## Resolve a milestone ID from a title
Needed whenever the only handle available is a title — e.g. a `pull_request_read` response, which
returns `milestone` as a bare title string rather than `{id, title}`. Call:
```
milestone_read method: "list" owner: <owner> repo: <repo> name: <title>
```
and take the `id` of the matching result. If `name` filtering returns no match (e.g. due to a
title typo or case mismatch), fall back to listing without the filter and matching manually.
## Create a milestone
```
milestone_write method: "create"
owner: <owner> repo: <repo>
title: "v1.0"
description: "First stable release"
due_on: "2025-03-01T00:00:00Z"
```
Report the returned ID — the caller (`gitea-issues`/`gitea-prs`) needs it to assign issues/PRs to
this milestone via `issue_write`/`pull_request_write`.
## Update or close a milestone
```
milestone_write method: "update" owner: <owner> repo: <repo> id: <id> state: "closed"
```
Only pass the fields being changed — `id` plus any of `title`/`description`/`due_on`/`state`.
## Delete a milestone
```
milestone_write method: "delete" owner: <owner> repo: <repo> id: <id>
```
Deleting a milestone does not delete or unassign the issues/PRs that referenced it — they simply
lose the milestone reference.
