Link Ticket To Session

You are linking the current Claude Code session (${CLAUDE_SESSION_ID}) to: $ARGUMENTS

Karma is a read-only observer on the user's machine. It stores the link and caches title/status for display, but never writes back to the ticket provider. You fetch metadata via the user's already-configured MCP server.

Karma's API URL comes from KARMA_API_URL (set by users on non-default ports/hosts) with http://localhost:8000 as fallback. Inline ${KARMA_API_URL:-http://localhost:8000} in every curl below — bash variables don't persist across separate Bash tool calls, so a top-of-script assignment would be empty by the time the next curl runs.

Step 1 — Parse $ARGUMENTS

Recognized forms:

GitHub issues and pull requests share a single numbering namespace — owner/repo#42 could be either. The URL kind (/issues/ vs /pull/) is the only signal, and karma's backend preserves it, so when you have a URL keep it intact when POSTing (Step 4). For a bare owner/repo#N with no URL, default to /issues/N — GitHub auto-redirects to /pull/N when N is actually a PR, so the link still resolves.

A bare #N (no owner/repo) is not accepted — always qualify with owner/repo#N.

Step 2 — Identify provider and (for GitHub) kind

Set two variables you'll use below:

• <provider> ∈ linear | jira | github
• For GitHub: <kind> ∈ issue | pull_request (derived from URL path)

For Linear and Jira this collapses to just <provider>.

Step 3 — Fetch metadata via MCP (when available)

Pick the right MCP tool for the provider and kind:

Calling the wrong GitHub method silently returns the wrong thing because both shapes look superficially similar — so derive the kind first.

If the relevant MCP isn't installed, skip this step and proceed to Step 4 without title/status. Karma will create the link; the title/status fields stay NULL and can be refreshed later via Step 5.

Pull at minimum: title, status (or state), url. Strip large fields — karma caps metadata_json at 64 KB and a full PR payload easily exceeds that. Specifically drop:

• GitHub PR: body, commits, files, reviewers, comments, labels, requested_reviewers, head / base blobs beyond ref
• GitHub issue: body, comments, reactions, labels
• Linear / Jira: description, comments, subscribers, attachments

Status semantics by kind

The status you cache should reflect what the provider says now, not a generic "open/closed". Karma's UI normalizes these to canonical buckets at render time, so faithful provider language is the right input:

• Linear: workflow state name verbatim — e.g. Backlog, In Progress, In Review, Done, Cancelled (workspace-defined; don't normalize).

• Jira: workflow state name — e.g. To Do, In Progress, In Review, Done.

• GitHub issue: open or closed.

• GitHub PR: derive from the flags the PR API returns:

  state	draft	merged	Cache as
  open	true	—	draft
  open	false	—	open
  closed	—	true	MERGED
  closed	—	false	closed

Step 4 — POST the link

The url field should be the URL you actually have — /pull/N for PRs, /issues/N for issues. Don't rewrite it. Karma's parser preserves the path segment; the UI uses it to distinguish PRs from issues.

curl -s -X POST "${KARMA_API_URL:-http://localhost:8000}/sessions/${CLAUDE_SESSION_ID}/tickets" \
     -H 'Content-Type: application/json' \
     -d '{"ref":"<key>","provider":"<provider>","url":"<url>","source":"slash_command"}'

For GitHub, <key> is always owner/repo#N regardless of kind — the URL field carries the issue/PR distinction.

Step 5 — PUT the metadata (only if Step 3 succeeded)

curl -s -X PUT "${KARMA_API_URL:-http://localhost:8000}/tickets/<provider>/<key>" \
     -H 'Content-Type: application/json' \
     -d '{"title":"<title>","status":"<status>"}'

For GitHub keys with / and #, URL-encode the key in the path: octocat/repo#42 → octocat%2Frepo%2342.

Step 6 — Confirm to the user

One line. For GitHub, distinguish the kind so the user knows what they just attached:

• Linked session to LINEAR-123 (Fix login bug, In Progress) — open at https://linear.app/...
• Linked session to PROJ-45 (Migrate auth, Done) — open at https://acme.atlassian.net/browse/PROJ-45
• Linked session to octocat/repo#42 [issue] (Empty state lies, open) — open at .../issues/42
• Linked session to octocat/repo#42 [PR] (Fix linting, MERGED) — open at .../pull/42

Notes

• Karma is loopback-only by default. KARMA_API_URL overrides for custom port or remote host.
• POST is idempotent on (session, ticket); re-running upgrades the link_source if previously set by branch-detect or dashboard. Order: slash_command > dashboard > branch.
• If the API is unreachable, tell the user karma not running at ${KARMA_API_URL:-http://localhost:8000} so they see what was tried. Don't silently succeed.
• GitHub issues and PRs sharing #N means a single karma row (one (provider, external_key) pair) covers both views of that number. The URL field is what tells karma's UI which one to render. Send the URL you actually have.
