Conciseness

The body is efficient — no explanations of concepts Claude already knows, and the tool and key-file tables are dense with information. Not score 5 because passages like 'the shared runner, which resolves only that allowlist under the persisted creator/org request context and never stores or exposes OAuth tokens, URLs, or arbitrary proxy targets' are wordy and could be tightened; above score 3 since the padding is minor and mostly carries non-obvious domain facts.

Actionability

Concrete guidance throughout: exact tool/action pairs ('manage-jobs' with 'create', 'list', 'update'), exact paths ('packages/core/src/jobs/cron.ts', '/agent#jobs'), and specific mechanics ('bind the exact advertised mcp__<server>__<tool> names through mcpTools'). Not score 5 because it never shows a job-file example or the scheduling frontmatter fields, leaving the main creation flow without a copy-paste-ready specimen; well above score 3, which would be pseudocode-level hints.

Workflow Clarity

The 'How It Works' section lays out a clear five-step sequence from user request to saved job results, and the primary action (create via manage-jobs) is unambiguous. Not score 5 because there are no validation checkpoints or error-recovery guidance (e.g., what to do when a cron expression is invalid, though isValidCron is mentioned only in a file table); the destructive/batch cap of 3 does not apply since no such operations are instructed.

Progressive Disclosure

Good single-file structure: well-labeled sections, tables, and clearly signaled one-level-deep pointers to sibling skills ('automations', 'actions', 'delegate-to-agent') and key source files. Not score 5 because the 'Connected MCPs' section is dense security/behavioral detail inlined in the overview that could be split out, and the body runs past the ~50-line threshold where a single well-organized file alone earns top marks; comfortably above score 3, which expects structure with mis-signaled or missing separation.

Specificity

The description names its domain concretely ("The legacy manage-jobs compatibility surface, job files under jobs/, and cron scheduler internals") but enumerates coverage areas rather than concrete actions like create/list/update jobs. It matches anchor 3 — domain plus 1-2 concrete items but not comprehensive — rather than 4, which requires several specific actions, or 2, which would leave actions entirely generic.

Completeness

It explicitly answers what ("legacy manage-jobs compatibility surface, job files under jobs/, and cron scheduler internals") and when ("Use when maintaining manage-jobs integrations or debugging the scheduler") with concrete trigger phrases. This matches the anchor-5 example structure; the 'when' clause is explicit and specific, so it is not score 4's weaker 'when'.

Trigger Term Quality

Good natural-keyword coverage: "manage-jobs", "jobs/", "cron", "scheduler", "integrations" are phrases a maintainer would actually say ("Use when maintaining manage-jobs integrations or debugging the scheduler"). Not score 5 because common synonyms like "recurring", "scheduled", or "scheduled tasks/automations" are absent; clearly above score 3, which expects only some relevant keywords with missing variations.

Distinctiveness Conflict Risk

The legacy framing ("The legacy manage-jobs compatibility surface") carves out a clear niche distinct from the primary automations model, so it is mostly distinct. Not score 5 because job/scheduler terminology overlaps with a sibling automations skill (the body confirms automations is the primary product model), leaving minor overlap risk; well above score 3's "could still overlap with similar skills".
