Conciseness

Nearly every sentence carries non-inferable project facts ('The refspec is explicit because a bare clone maps no remote-tracking refs'; 'Session-metrics cards join transcripts by branch name alone'), with no explanation of concepts Claude already knows. The prose is compressed and information-dense, matching the lean top anchor rather than the 4 anchor's 'minor instances of over-explanation'.

Actionability

Copy-paste-ready commands with placeholders for every path: 'gh issue view 412 --repo …', 'git worktree add /Users/ac/.work/osn.git/<dir> -b <branch> origin/main', the name-taken check (cat-file -e plus gh api 'pulls?state=all&head=…'), and 'bun install --frozen-lockfile'. It covers the common cases — PERSONAL vs REMOTE, existing issue vs new, no network, no gh — with concrete fallback behavior for each.

Workflow Clarity

Four explicitly ordered steps ('each depends on the one before'), a preflight gate probe ('Find out once, before Step 0'), validation before risky operations (check the branch name is free before cutting; 'Cut once'; idempotent '-B makes a re-run idempotent… switch without resetting'), and a feedback loop in Step 3 (every stress-plan finding fixed, rejected in writing, or escalated before implementation starts). Honesty checkpoints like 'Never describe an issue as opened… when the command could not run' round out the top anchor.

Progressive Disclosure

The one bundle reference ('The routing table is references/skills-routing.md') is real, clearly signaled, and one level deep, and the skill delegates heavily to other skills and wiki pages rather than inlining them. However, the ~145-line body carries dense inline checklists (Step 2's plan requirements, the complexity-rating rules) that could partly live in reference files, which fits anchor 4 ('minor organization gaps') rather than 5.

Specificity

The description lists multiple concrete actions — 'taking or opening its GitHub issue, cutting the branch (a worktree on the local bare repo, an in-place branch on the remote environment) and producing the implementation plan, including the wiki pages the work will make stale and its observability plan' — with comprehensive coverage of the workflow including the tracker-finding edge case. Coverage has no meaningful gaps, so it sits at the top anchor rather than 4.

Completeness

It explicitly answers both: 'Use when starting a piece of feature or fix work in this repository' (when, with a concrete trigger phrase) and the full set of artifacts produced, plus 'Also the step for turning a tracker finding into a branch without publishing it' as a second concrete trigger. The 'when' is already explicit and specific, so it is not the 4 anchor.

Trigger Term Quality

Good natural keyword coverage — 'feature or fix work', 'GitHub issue', 'branch', 'implementation plan', 'tracker finding' — terms a user starting work would plausibly say. It misses common variations and synonyms ('new work', 'bugfix', 'start a task'), which keeps it below the comprehensive synonym-level anchor 5 but above anchor 3.

Distinctiveness Conflict Risk

A clear repo-specific niche with distinct triggers — 'tracker finding', 'worktree on the local bare repo', 'observability plan' — that no general-purpose skill would overlap with. Minimal conflict risk.
