claim-issue

Claim a GitHub issue and set up an isolated workspace to work on it. Works in Claude Code and Codex (read the same file).

Inputs

Accept either form via $ARGUMENTS or by parsing the user's message:

• Issue number: 123
• Full URL: https://github.com/getlarge/themoltnet/issues/123

Default repo: getlarge/themoltnet. If a URL points to a different repo, refuse and ask the user to confirm — this skill is scoped to MoltNet.

Steps

Minimize user confirmations. Prefer at most two confirmations for the whole workflow:

1. a read-only / metadata phase: resolve the agent identity if needed, mint the agent GH_TOKEN, and fetch the issue metadata
2. a mutation phase: fetch origin/main, create the worktree + branch, assign the issue, and attempt the project-board add

Still print the exact command or command batch before running it, but batch related shell commands together unless a failure mode requires a decision point. If a command needs network or sandbox escalation, request that escalation directly instead of doing an extra confirmation-only round trip first.

1. Load the legreffier skill first

Before any gh or git work, invoke the legreffier skill (via Skill in Claude Code, equivalent loader in Codex). Legreffier knows:

• How to resolve AGENT_NAME from GIT_CONFIG_GLOBAL / MOLTNET_AGENT_NAME / .moltnet/ layout
• How to mint a GH_TOKEN from .moltnet/<AGENT_NAME>/moltnet.json per .claude/rules/legreffier-gh.md
• How to handle worktree symlinking of .moltnet/

Don't duplicate that logic here. Once legreffier is active, the rest of the steps just use the gh/git patterns it established.

2. Fetch issue metadata

GH_TOKEN=$(moltnet github token --credentials "<ABSOLUTE-CREDS-PATH>") \
  gh issue view <N> --repo getlarge/themoltnet --json number,title,labels,state,url

Run with the agent GH_TOKEN resolved by legreffier (per the legreffier-gh rule) using an absolute path to .moltnet/<AGENT_NAME>/moltnet.json. Do not use --agent; the stable CLI form is --credentials <absolute-path>. If moltnet github token returns empty, stop rather than letting gh fall back to the human token.

Use the title to derive a branch slug:

• Lowercase, replace non-alphanumerics with -, collapse repeats, trim ends
• Truncate to ~40 chars at a word boundary
• Branch name: issue-<N>-<slug> (e.g. issue-456-fix-keto-policy-drift)

Show the derived branch name and the planned worktree path. If state is closed, ask whether to proceed. Otherwise, use this as the end of the read-only phase and get a single confirmation for the mutation batch.

3. Create worktree + branch from origin/main

Always branch from a freshly fetched origin/main, not local main.

git fetch origin main
WORKTREE="../themoltnet-issue-<N>"
git worktree add -b issue-<N>-<slug> "$WORKTREE" origin/main

Batch this with steps 4, 5, and 6 when asking for the mutation-phase confirmation. Print the absolute worktree path.

After the worktree is created, install workspace dependencies there so the branch is immediately runnable:

pnpm install

Run it inside the new worktree path. If the workspace already shares node_modules another way, this may be a quick no-op; otherwise it bootstraps the branch for test and build work.

4. Install dependencies in the new worktree

pnpm install

Run from the new worktree root. If it fails because of sandboxed network access, rerun with escalation rather than asking the user to debug package-manager plumbing manually.

5. Assign issue to legreffier

GH_TOKEN=$(moltnet github token --credentials "<ABSOLUTE-CREDS-PATH>") \
  gh issue edit <N> --repo getlarge/themoltnet --add-assignee legreffier

Verified working with the agent token (2026-05).

6. Try to add issue to MoltNet Agent Board (project #3)

GH_TOKEN=$(moltnet github token --credentials "<ABSOLUTE-CREDS-PATH>") \
  gh project item-add 3 --owner getlarge --url https://github.com/getlarge/themoltnet/issues/<N>

This will likely fail. Don't treat it as a blocker.

If it fails with Could not resolve to a ProjectV2 with the number 3: the token lacks project scope. This is GitHub's misleading way of reporting a scope failure rather than a 404. Explain to the user:

The agent's GitHub App token doesn't carry project scope (GitHub Apps don't grant it alongside contents/issues/pulls), so this step can't be automated under legreffier. Your personal gh token also needs project scope — if you want to run this step yourself, do it once:

gh auth refresh -s project
gh project item-add 3 --owner getlarge --url https://github.com/getlarge/themoltnet/issues/<N>

Or add it via the web UI: https://github.com/users/getlarge/projects/3

Project metadata for reference: owner getlarge, number 3, id PVT_kwHOAOnyU84BOd17.

Continue to step 7 regardless of outcome.

7. Hand off

Report a 4-line checklist of what actually ran vs. was skipped:

• [x/!] legreffier skill loaded
• [x/!] worktree created at <path> on branch issue-<N>-<slug>
• [x/!] issue assigned to legreffier
• [x/!/manual] added to MoltNet Agent Board

Tell the user to cd into the worktree before starting the actual work, so subsequent git commits land on the new branch and the diary entries pick up the right agent identity.

Failure modes to surface, not hide

• gh falls back to personal token (rule violation): if legreffier's GH_TOKEN resolution returns empty, stop. Don't run any gh command bare — the action would be attributed to the human.
• Branch already exists: git worktree add -b fails. Offer git worktree add "$WORKTREE" issue-<N>-<slug> (no -b) to reuse the existing branch instead of silently overwriting.
• Worktree path collision: pick ../themoltnet-issue-<N>-<n> with an incrementing suffix and tell the user why.
• Issue not found / wrong repo: stop before creating a branch.
• Network/sandbox boundary: if gh or git fetch fails due to sandboxed network access, rerun with escalation immediately instead of asking for a separate manual confirmation first.
