Conciseness

The redirect core is lean, but the Quick Start block (global npm install, sandbox registry fallback, `auth register --wait auto`, `auth wait`) is operational setup that belongs in the target skill and directly contradicts the body's own claim that it 'contains no instructions of its own'. This matches 'mostly efficient but includes some unnecessary explanation'; not 2 because the rest of the body is tight and the block is small.

Actionability

Guidance is concrete and executable: a copy-paste bash loop probing three exact candidate roots ('.skills/deepline-scoring', '.claude/skills/...', '.agents/skills/...') plus explicit loader-name invocation. Not 5 because the body never states when (or whether) the Quick Start commands should actually run relative to the redirect, leaving a gap between the setup section and the 'What to do' flow.

Workflow Clarity

The single-purpose redirect sequence is unambiguous (load target skill → 'tell the user once, in a single line' → continue with the request), with a fallback resolution path for loaders without name support. Not 5 because the unexplained Quick Start section sits outside the stated workflow, leaving unclear whether the agent should execute it before redirecting; not 3 because the redirect steps themselves are complete with no risky operations requiring validation.

Progressive Disclosure

The body is under 50 lines with no bundle files, organized into clear sections (Quick Start, What to do), and its single reference (the `deepline-scoring` entrypoint) is one level deep and clearly signaled — matching the simple-skill case for well-organized structure with no separate files needed.

Specificity

States its concrete role and action explicitly ('Deprecated alias. This skill was renamed to `deepline-scoring`... immediately load and follow the `deepline-scoring` skill instead'), matching 'lists several specific actions; minor gaps'. Not 5 because capability detail is intentionally delegated to the target skill, so coverage is not comprehensive within the description itself.

Completeness

Explicitly answers both what ('Deprecated alias... load and follow the `deepline-scoring` skill instead') and when ('Use when a user or script still invokes `/niche-signal-discovery`' plus a dedicated Triggers list), matching the anchor for clear and explicit what AND when with concrete trigger phrases.

Trigger Term Quality

The Triggers list gives good natural-phrase coverage with synonyms ('ICP analysis, niche signals, won vs lost analysis, differential signals, signal discovery, ICP signal report, account scoring signals, lead scoring, first-party signals, buyer signals'), matching 'good keyword coverage; a few natural terms missing'. Not 5 because a few plausible variations (e.g., win/loss review, deal analysis) are absent.

Distinctiveness Conflict Risk

Scoped to a deprecated alias with a clear niche (invocations of the old name), matching 'mostly distinct; minor overlap risk'. Not 5 because its broad trigger list (lead scoring, buyer signals) overlaps the canonical deepline-scoring skill's own triggers, though the redirect makes the conflict largely benign.
