Conciseness

Dense and domain-specific, assuming Claude's knowledge of worktrees, migrations, and PRs without padding; the OAuth/form-rendering sections could be tightened slightly but every token earns its place with concrete file paths and gotchas.

Actionability

Provides exact file paths, exact commands (`python manage.py makemigrations signals`), concrete switch-case routing, and a copy-paste worktree block; falls just short of 5 because the emitter step says to copy and adapt github_issues.py rather than giving complete code.

Workflow Clarity

Multi-step processes are clearly sequenced across the posthog/posthog and posthog/code checklists with explicit deploy-ordering dependencies and dedicated 'Verify' checkpoints, including validation for the destructive migration step (`makemigrations --check`).

Progressive Disclosure

No references/scripts/assets bundle exists, so all detail — the full Tier-1 catalog table and the per-source checklists — is inlined in one ~250-line file; cross-references to other skills exist, but content that could be offloaded to one-level-deep reference files is not split out.

Specificity

Lists multiple concrete actions — syncing a warehouse table, a signals scout emitting findings, wiring three named surfaces, deploy ordering, and created_via attribution — giving comprehensive coverage of the domain with no vague filler.

Completeness

Explicitly answers both 'what' (add a warehouse-backed source to the Self-driving Inbox) and 'when' (a clear 'Use when...' clause with concrete trigger phrases).

Trigger Term Quality

Provides natural trigger phrases users would actually say ('add a new inbox/self-driving source', 'wire up <Jira/GitLab/Sentry/Intercom/...> as a signal source', 'extend the source-toggle grid') with broad synonym coverage of named providers.

Distinctiveness Conflict Risk

Occupies a very specific niche (PostHog Self-driving Inbox sources across three named repos) with distinct triggers and minimal overlap risk with other skills.
