Conciseness

Largely efficient — every section carries non-obvious, skill-specific rules (verification gate definition, "Never invent IDs", self-containment rule) and no space is spent on concepts Claude already knows. Fits anchor 4 rather than 5 because of minor padding: the verification criterion is repeated across the intro, "The One Principle", and the phase table, and the execution model over-illustrates with "no 'ready to continue?', no 'shall we create it?', no 'want me to proceed?'").

Actionability

Gives concrete, executable instruction for an orchestrator skill: named tools (`aiagents_list`, `projects_list`/`projects_create`), "actually call the tool", "call the relevant list/retrieve tool" for IDs, and a per-phase execution loop (announce → read phase file → satisfy gate → move on). Anchor 4 rather than 5 because the actual per-phase steps are entirely deferred to the phase files, so the body alone leaves minor execution gaps.

Workflow Clarity

Clear sequence via the phase table with shared/testing/observability paths, explicit validation gates ("verification gate" on phases 5T and 3O; onboarding "is done when one test call completed and its transcript is visible"), a feedback loop ("If a call fails, fix the cause or ask for the missing input, then retry; never claim a step is done until the call succeeds"), and defined blocker handling. Matches anchor 5's explicit validation, feedback loops, and error-recovery guidance.

Progressive Disclosure

The design is good — an overview body with a phase table pointing to one-level-deep per-phase files plus references/ — but scored against the actual bundle, 10 of the 12 referenced paths (`phase0-path.md`, `phase2-agent.md`, all `phase3`-`phase6` files) do not exist; only `references/api-quickstart.md` and `references/client-setup.md` are present. The core navigation mechanism ("Read the phase file") therefore cannot function, which is more than the "minor organization gaps" of anchor 4, while the structure and existing references are too well-signaled for anchor 2.

Specificity

Names the domain and several concrete actions — "build evaluators and run simulated calls", "ingest production call logs and evaluate them" — covering both onboarding paths with only minor gaps (e.g., agent connection is only implied via "help me set up my agent"). Fits anchor 4 rather than 3 because more than 1-2 actions are listed, but not 5 because the full setup loop (connect agent, verify first result) is only indirectly described.

Completeness

Explicitly answers both: what ("Covers two onboarding paths: **testing** (default — build evaluators and run simulated calls) and **observability** (ingest production call logs and evaluate them)") and when ("Use when the user says...") with concrete trigger phrases. Matches the anchor-5 pattern of concrete actions plus explicit trigger guidance; not 4 because the when-clause is fully explicit rather than merely adequate.

Trigger Term Quality

Comprehensive natural-language triggers users would actually say: "get started with Cekura", "set up Cekura", "I'm new to Cekura", "walk me through Cekura", "first time using Cekura", plus the /cekura-onboarding command and a generic "needs guidance on initial platform setup" catch-all. Coverage includes synonyms and phrasing variations; nothing obvious is missing.

Distinctiveness Conflict Risk

Clear niche with brand-specific triggers and an explicit negative boundary — "Not for adding an agent, more scenarios or more metrics to an existing workspace — those are cekura-create-agent, cekura-eval-design and cekura-metric-design" — which actively routes away from the sibling skills. Minimal conflict risk.
