Conciseness

The body is mostly lean and free of concept explanations Claude already knows, but it instructs "pnpm install" twice — once appended to step 3 ("install workspace dependencies there so the branch is immediately runnable... Run it inside the new worktree path") and again as the entirety of step 4 ("Install dependencies in the new worktree... Run from the new worktree root") — duplicating an entire step. A time-sensitive stamp ("Verified working with the agent token (2026-05)") is also inlined rather than placed in a notes/deprecated section. This matches "mostly efficient but could be tightened" rather than level 4's "minor instances"; well above level 2 since there is no padded explanation.

Actionability

Fully executable, copy-paste-ready commands cover every step: "gh issue view <N> --repo getlarge/themoltnet --json number,title,labels,state,url", "git fetch origin main; git worktree add -b issue-<N>-<slug> \"$WORKTREE\" origin/main", "gh issue edit <N> --add-assignee legreffier", and "gh project item-add 3 --owner getlarge --url ...", plus concrete branch-slug derivation rules and exact recovery commands for each failure mode. Not level 4: there are no gaps in covering the common cases.

Workflow Clarity

Steps 1–7 are clearly sequenced with an explicit read-only vs. mutation phase split, validation checkpoints (stop if GH_TOKEN resolution returns empty, ask whether to proceed if issue state is closed, a single mutation-phase confirmation), error-recovery guidance in the failure-modes section, and a final 4-line hand-off checklist. Not level 4: checkpoints are explicit and complete rather than mostly present; the workflow involves no destructive or batch operations that lack validation.

Progressive Disclosure

The skill is a single self-contained file with well-organized sections (Inputs, phased Steps, Failure modes) and no bundle files to reference, so navigation is easy and nothing is buried. Not level 5: at ~130 lines, with the ~15-line project-board failure explainer and its quoted user-facing message inlined, some content could arguably live in a reference file, and the sections-only exception applies to skills under 50 lines. Clearly above level 3 since the structure is good and clearly signaled.

Specificity

The description enumerates four concrete actions — "load the legreffier skill", "create a worktree + branch from origin/main", "assign the issue to legreffier", and "try to add it to the MoltNet Agent Board project" — giving comprehensive coverage of the claim workflow. Not level 4 because there are no coverage gaps: every stage of the workflow is explicitly named.

Completeness

Both what ("Claim a GitHub issue for work — load the legreffier skill, create a worktree + branch from origin/main, assign the issue to legreffier, and try to add it to the MoltNet Agent Board project") and when ("Use when the user says 'let's work on issue <N>', 'claim <issue-url>', 'start issue <N>', or pastes a getlarge/themoltnet issue URL") are explicitly stated with concrete trigger phrases, matching the top anchor.

Trigger Term Quality

Natural trigger phrases are present ("let's work on issue <N>", "claim <issue-url>", "start issue <N>", pasting an issue URL with intent to work on it), which is good keyword coverage. Not level 5 because common synonyms such as "take", "grab", or "pick up an issue" are missing; clearly above level 3 since multiple natural phrasings users would actually say are covered.

Distinctiveness Conflict Risk

The description is scoped to a clear niche — claiming issues in getlarge/themoltnet via the legreffier agent and the MoltNet Agent Board — with trigger phrases that would not fire for generic git, worktree, or issue-management skills. Minimal conflict risk; not level 4 since even closely related skills are unlikely to overlap on these triggers.
