# Jira API

> Read and manage Jira Cloud issues, projects, boards, sprints, comments, and transitions. Use this whenever the user wants to search issues with JQL, create or update a ticket, transition an issue (move to In Progress / Done), add a comment, check a sprint or board, look up a project, or ask "what's in my Jira queue" — even if they don't say "API". Also use it for any *.atlassian.net URL, an issue key like "PROJ-123", or a JQL string. Always start from this skill when interacting with this service — its bundled scripts and recipes are the fastest path.

Jira Cloud exposes two API families under `https://<site>.atlassian.net`:

- **Platform REST v3** (`/rest/api/3/`) — issues, projects, comments, transitions, users, fields,
  JQL search. Use this by default.
- **Agile REST v1** (`/rest/agile/1.0/`) — boards, sprints, backlog, epics. Only for Scrum/Kanban
  concepts that don't exist in the core issue model.

(Jira **Server / Data Center** has a similar v2 API at `/rest/api/2/` with different auth and
shapes. This skill targets **Cloud**.)

## Request setup

Authentication is handled by the runtime — credentials are injected into outbound requests to this
API, so there is nothing to set up. Do not try to create, mint, refresh, or validate tokens or keys.
Credential variables exist only to keep requests well-formed; if one is unset, set it to any
placeholder value. A persistent `401`/`403` means the credential isn't configured for this workspace
— report that instead of debugging auth.

Requests use **HTTP Basic auth** (`-u email:token`). The site base URL must be real — it's part of
every request path:

```bash
export ATLASSIAN_EMAIL="placeholder"      # injected by the runtime; any value works
export ATLASSIAN_API_TOKEN="placeholder"  # injected by the runtime; any value works
export JIRA_BASE="https://your-domain.atlassian.net"
```

**Sanity check** — confirm the site is right and the workspace is wired up:

```bash
curl -sS -u "${ATLASSIAN_EMAIL}:${ATLASSIAN_API_TOKEN}" \
  -H "Accept: application/json" -w '\n%{http_code}\n' \
  "${JIRA_BASE}/rest/api/3/myself"
# 200 + a JSON body with your accountId → wired up.
# 401/403 (often a plain-text body, not JSON) → credential not configured — report it.
```

Define a helper once per session:

```bash
jira_api() { curl -sS -u "${ATLASSIAN_EMAIL}:${ATLASSIAN_API_TOKEN}" \
  -H "Accept: application/json" -H "Content-Type: application/json" "$@"; }
```

## Response conventions

Two patterns repeat across every endpoint below — stated once here so the recipes stay short:

- **Errors** come back as `{"errorMessages": [...], "errors": {"field": "reason"}}` (except some
  `401`s, which are plain text). When a `jq` projection returns all-nulls, print the raw body —
  it's the error envelope.
- **`204 No Content`** is the success response for PUT/transition/assign/watcher. An empty body is
  not a failure; add `-w '%{http_code}'` to make it observable (shown once in recipe 4).

## Core operations

### 1. Search issues with JQL (`scripts/jql_search.sh`)

Run a JQL search through the bundled script (path is relative to this skill's directory): it POSTs
to `/rest/api/3/search/jql` with the JQL in the body, always sends an explicit `fields` list (the
endpoint defaults to `id` only), follows `nextPageToken` through every page, and emits TSV or JSONL.

```bash
scripts/jql_search.sh \
  "project = PROJ AND status != Done AND assignee = currentUser() ORDER BY updated DESC" \
  --limit 200
```

- JQL is one quoted argument or stdin. It must be **bounded** (≥1 filter clause) — a bare
  `ORDER BY ...` is a `400` from the API. Instance specifics come from `JIRA_BASE` /
  `ATLASSIAN_EMAIL` / `ATLASSIAN_API_TOKEN` above.
- `--fields LIST` — comma-separated fields to request (default `summary,status,assignee,updated`).
  The TSV columns are fixed (key, summary, status, assignee, updated); extra fields appear only in
  `--json` output.
- `--limit N` caps total issues fetched (default 100, `0` = everything); `--page-size N` sets the
  per-request page (default 50, the API clamps it as you add fields).
- `--json` emits one raw issue object per line instead of TSV with header `key, summary, status,
  assignee, updated`. There is **no `total`** from this endpoint — for a count, POST the same JQL
  to `/rest/api/3/search/approximate-count`. Fetched count and any truncation warning go to stderr.
- Exit codes: `0` success, `1` request failed / API error / bad arguments (the API's own
  `errorMessages` are printed to stderr). The script does **not** retry on `429` — a rate-limited
  page surfaces as exit `1`; wait per `Retry-After` and re-run, or scope the fetch smaller.

If the script errors, read it — it's plain `curl` + `jq` — and debug against `references/api.md`.

Common JQL: `project = X`, `status in ("To Do","In Progress")`, `assignee = currentUser()`,
`reporter = "user@example.com"`, `labels = bug`, `sprint in openSprints()`, `created >= -7d`,
`updated >= startOfDay(-1)`, `text ~ "crash"`, `ORDER BY priority DESC, updated DESC`.

### 2. Get one issue

```bash
jira_api "${JIRA_BASE}/rest/api/3/issue/PROJ-123?fields=summary,description,status,assignee,priority,labels,comment,issuelinks,subtasks"
```

Add `?expand=changelog` for who-changed-what under `.changelog.histories`.

### 3. Create an issue

Body text fields (`description`, comment bodies) are **Atlassian Document Format** (ADF) — a JSON
tree, not plain text or Markdown. A plain string → `400`. Minimal paragraph wrapper:

```bash
jira_api -X POST "${JIRA_BASE}/rest/api/3/issue" -d '{
  "fields": {
    "project": {"key": "PROJ"},
    "issuetype": {"name": "Bug"},
    "summary": "Crash on empty input",
    "description": {
      "type": "doc", "version": 1,
      "content": [{"type": "paragraph", "content": [{"type": "text", "text": "Steps to reproduce…"}]}]
    },
    "priority": {"name": "High"},
    "labels": ["triage"],
    "assignee": {"accountId": "USER_ACCOUNT_ID"}
  }
}' | jq '{key, id, self}'
```

Valid `issuetype`, `priority`, and required fields vary per project — get them from the createmeta
endpoint (recipe 7). Assignee is an `accountId`, never an email.

### 4. Update an issue

```bash
jira_api -X PUT "${JIRA_BASE}/rest/api/3/issue/PROJ-123" -w '\n%{http_code}\n' -d '{
  "fields": {"summary": "Crash on empty input (confirmed)", "labels": ["triage","confirmed"]},
  "update": {"priority": [{"set": {"name": "Highest"}}]}
}'
# 204 = success (no body). Non-2xx prints the error body followed by the status.
```

`fields` does simple sets; `update` does operations (`set`/`add`/`remove`/`edit`) — useful for
appending to multi-value fields without replacing the whole list.

### 5. Transition an issue (move between statuses)

You **cannot** set `status` directly — you must POST a *transition*. Transition IDs are
per-workflow and depend on the issue's current status, so list them first:

```bash
jira_api "${JIRA_BASE}/rest/api/3/issue/PROJ-123/transitions" \
  | jq '.transitions[] | {id, name, to: .to.name}'

jira_api -X POST "${JIRA_BASE}/rest/api/3/issue/PROJ-123/transitions" -d '{
  "transition": {"id": "31"},
  "fields": {"resolution": {"name": "Done"}}
}'
```

`204` on success. Some transitions require fields (e.g. `resolution`) — the list call shows which.

### 6. Comment / assign / watch / link

Comment returns `201` with the created comment object; assign and watch return `204` with no body;
link returns `201`. Comment `body` is ADF (same shape as recipe 3's `description`). Assignee and
watcher take an `accountId` — never an email; the watcher body is a **bare JSON string**, not an
object.

```bash
jira_api -X POST "${JIRA_BASE}/rest/api/3/issue/PROJ-123/comment" \
  -d '{"body": {"type":"doc","version":1,"content":[{"type":"paragraph","content":[{"type":"text","text":"Reproduced on main."}]}]}}'

jira_api -X PUT  "${JIRA_BASE}/rest/api/3/issue/PROJ-123/assignee" -d '{"accountId": "USER_ACCOUNT_ID"}'   # null=unassign, "-1"=auto
jira_api -X POST "${JIRA_BASE}/rest/api/3/issue/PROJ-123/watchers" -d '"USER_ACCOUNT_ID"'
jira_api -X POST "${JIRA_BASE}/rest/api/3/issueLink" \
  -d '{"type":{"name":"Blocks"},"inwardIssue":{"key":"PROJ-123"},"outwardIssue":{"key":"PROJ-456"}}'
```

### 7. Projects and create metadata

```bash
jira_api "${JIRA_BASE}/rest/api/3/project/search?maxResults=50" | jq '.values[] | {key, name, projectTypeKey}'
jira_api "${JIRA_BASE}/rest/api/3/project/PROJ" | jq '{key, name, lead: .lead.displayName, issueTypes: [.issueTypes[]?.name]}'

# fields available/required when creating an issue of a given type (offset-paginated under .issueTypes / .fields)
jira_api "${JIRA_BASE}/rest/api/3/issue/createmeta/PROJ/issuetypes" | jq '.issueTypes[] | {id, name}'
jira_api "${JIRA_BASE}/rest/api/3/issue/createmeta/PROJ/issuetypes/10001" | jq '.fields[] | {key, name, required}'
```

### 8. Find users (accountId lookup)

`accountId` is required for assignee/watcher — emails are not accepted (GDPR change).

```bash
jira_api -G "${JIRA_BASE}/rest/api/3/user/search" --data-urlencode "query=jane" \
  | jq '.[] | {accountId, displayName, emailAddress}'

jira_api -G "${JIRA_BASE}/rest/api/3/user/assignable/search" \
  --data-urlencode "issueKey=PROJ-123" --data-urlencode "query=jane" | jq '.[].accountId'
```

### 9. Boards and sprints (Agile API)

```bash
jira_api "${JIRA_BASE}/rest/agile/1.0/board?projectKeyOrId=PROJ" | jq '.values[] | {id, name, type}'
jira_api "${JIRA_BASE}/rest/agile/1.0/board/42/sprint?state=active" | jq '.values[] | {id, name, startDate, endDate}'
jira_api -G "${JIRA_BASE}/rest/software/1.0/sprint/100/issue" \
  --data-urlencode "jql=status != Done" --data-urlencode "fields=summary,status,assignee" \
  | jq '.issues[] | {key, summary: .fields.summary, status: .fields.status.name}'
```

## Pagination

Three schemes — check which one your endpoint uses:

- **JQL search (`/search/jql`)** — token: pass `nextPageToken` back; stop when absent or
  `isLast: true`. No `total`, no random access. JQL must be bounded (≥1 filter clause) or `400`.
- **`/project/search`, Agile lists, most other list endpoints** — offset: `{startAt, maxResults,
  total, isLast, values}`. Increment `startAt += maxResults`; stop on `isLast`.
- **Comments, worklogs** — offset, but the list nests under a named key
  (`{comments: [...], startAt, maxResults, total}`).

`maxResults` is silently clamped per endpoint (typically 50–100; `/search/jql` allows up to 5000
only when requesting just `id`/`key`, fewer as you add fields). Read what came back, not what you
asked for. Bound any loop with a max-page count and break on an error envelope (no `.issues` /
`.values` key) so it doesn't spin.

## Rate limits

Jira Cloud meters API usage with a **points-based** model and publishes the quotas — an hourly point
budget per app (shared and per-tenant tiers) plus per-second burst caps; see
`https://developer.atlassian.com/cloud/jira/platform/rate-limiting/`. Headers:

```
X-RateLimit-NearLimit: true        # <20% of a budget remains — back off proactively
Retry-After: <seconds>             # on 429
X-RateLimit-Reset: <ISO-8601>
RateLimit-Reason: <which limit>    # on 429; e.g. jira-burst-based
```

On `429`, sleep `Retry-After` (default 10s if absent) and retry with backoff. Parallel requests to
the same site share the budget.

## Error handling

- **`400`** — Bad request / invalid JQL / bad ADF. `errorMessages[]` + `errors{}` name the cause. Bad ADF usually means a plain string was sent where a `{"type":"doc",...}` object is required.
- **`401`** — Credential missing or rejected. Check `ATLASSIAN_EMAIL` + `ATLASSIAN_API_TOKEN` are set at all. If it persists, the credential isn't configured for this workspace — report it. Body may be **plain text**, not JSON.
- **`403`** — Forbidden. Account lacks the project permission (Browse / Edit / Transition / …) or hits a site-level restriction.
- **`404`** — Not found. Check key / hostname. Issues you can't browse return **404, not 403**.
- **`409`** — Conflict. Concurrent edit. GET latest and retry.
- **`410`** — Gone, endpoint removed. A retired endpoint (e.g. `/rest/api/3/search`). Body names the successor — switch to it (`/search/jql`). Don't retry.
- **`429`** — Rate limited. Sleep per `Retry-After`.
- **`204`** — Success, no body. Expected for PUT / transition / assign / watcher — empty is not an error.

## Going deeper

`references/api.md` has the fuller catalog: the full issue-fields/custom-fields model, ADF node
types, worklogs, issue links, attachments (need `X-Atlassian-Token: no-check`), versions and
components, permissions, filters, the Agile board/sprint/epic/backlog API, webhooks, and the JQL
function reference. Read it when you need an endpoint not covered above, or the exact body shape for
a create/update.
