Conciseness

No basic-concept padding (it assumes Claude knows what a DPU/library is), but the same primitive enumeration (log/buf/ctx/dev/progress engine) is repeated 5–6 times across 'Where to start', 'Example questions', 'When to load', 'What this skill provides', and 'Loading order', which could be tightened to one canonical list. It is not a 2 because the verbosity is structural repetition rather than explaining things Claude already knows.

Actionability

Concrete, specific routing — exact file+section anchors (CAPABILITIES.md ## ctx, TASKS.md ## configure), a real command ('pkg-config --modversion doca-common'), and sample paths (/opt/mellanox/doca/samples/<library>/<sample>/*_main.c). It is a deliberate no-code loader, so the absence of code is by design; the minor gap is that most guidance is routing rather than directly executable steps.

Workflow Clarity

A clear 3-step Loading Order (read SKILL.md → CAPABILITIES.md → TASKS.md) and per-question-class routing to specific anchors. No validation checkpoints are needed because this is a pure loader (no destructive/batch operations to guard), so the simple-skill rationale applies; not a 5 only because the 'Example questions' mappings are prose-heavy rather than a crisp sequenced checklist.

Progressive Disclosure

Well-signaled, one-level-deep references with markdown links and anchors to two companion files plus cross-links to sibling skills — structurally a 5. It drops to 4 because the referenced companion files (CAPABILITIES.md, TASKS.md) are not present in the skill bundle (no references/scripts/assets dirs), so the disclosure points to detail that is not actually shipped here.

Specificity

Lists multiple concrete actions — 'walking the doca_ctx lifecycle', 'discovering doca_dev / doca_devinfo and gating on doca_*_cap_*', 'wiring doca_mmap / doca_buf_inventory / doca_buf for zero-copy I/O', 'driving doca_pe for completions', and the two-tier log model — giving comprehensive, non-abstract coverage.

Completeness

Explicitly answers both what (the foundation primitives enumerated) and when ('Use this skill whenever...', plus 'Trigger even when the user does not say DOCA Common — typical implicit phrasings include...'), and adds explicit refuse/route guidance.

Trigger Term Quality

Gives natural symptom phrasings a user would actually say ('my tasks submit but nothing completes', 'DOCA_ERROR_BAD_STATE from doca_ctx_start', 'share a buf between doca_dma and doca_rdma', 'crashes far from the offending line'), which is exactly the 'would a user naturally say this' test; not just technical jargon.

Distinctiveness Conflict Risk

Clear niche (doca-common foundation primitives under every per-library context) with explicit routing away from per-library questions in isolation, install (doca-setup), and doc lookup (doca-public-knowledge-map), minimizing conflict with sibling skills.
