Conciseness

The body is dense and efficient — tables, terse bullets, and concrete YAML with no explanation of concepts Claude already knows. However, several rules are repeated three to four times (SBOM sequencing appears in the interaction model, insertion rules, Performance Notes, and Troubleshooting; 'do not execute the pipeline' likewise recurs four times), so not quite 'every token earns its place' (5) — it sits at the 4 anchor ('efficient; minor instances that could be trimmed').

Actionability

Guidance is fully executable: copy-paste-ready YAML for the step (with real values like `lavakush07/easy-buggy-app:blog`), concrete MCP invocations with parameters (`harness_update` with resource_type/org_id/project_id/body), a phase-by-phase table, and troubleshooting entries pairing symptoms with fixes. Matches the 5 anchor ('fully executable; copy-paste ready; specific examples cover the common cases').

Workflow Clarity

The 10-phase wizard is explicitly sequenced with a breadcrumb, a 13-point mandatory interaction model acts as a checklist, and risky write operations are gated: 'Fetch before configure', 'Confirm before write', and an explicit error-recovery loop ('On validation errors, read the API message, fix fields... retry'). This matches the 5 anchor's validation steps, feedback loops, and checklists.

Progressive Disclosure

Structure is good and references are real, clearly signaled, and one level deep (interactive-wizard-flow.md, slsa-generation-step.md, cd-containerized-step-group.md), with bulk detail (full phase prompts, per-registry specs, CD rules) correctly delegated. But the ~280-line body still inlines material that belongs in references — the entire output summary template and an extensive Troubleshooting section — fitting the 4 anchor ('most content appropriately placed; minor organization gaps') rather than the 5 anchor's lean overview.

Specificity

The description lists multiple concrete actions with comprehensive coverage: "Add a SLSA Generation step (YAML type: provenance) to an existing Harness pipeline to generate SLSA provenance and optionally attest with Cosign (keyless, key-based, or Vault)" plus enumerated supported sources (Docker, ECR, GCR, GAR, ACR, HAR, Harness Local Stage). This matches the 5 anchor ('multiple specific concrete actions; comprehensive coverage') and is well above the 4 anchor's 'minor gaps in coverage'.

Completeness

Both 'what' (add a provenance-type step to an existing Harness pipeline, generate SLSA provenance, optionally attest with Cosign) and 'when' are explicitly and concretely answered: "Use when asked to generate SLSA, add SLSA provenance, SLSA Generation step, attest SLSA, or configure SLSA Level 3 provenance in a pipeline" — a textbook match for the 5 anchor. Voice is third person, so no specificity penalty applies.

Trigger Term Quality

Trigger coverage is comprehensive with natural synonyms and variants: "generate SLSA, SLSA generation, add SLSA step, SLSA provenance, attest SLSA, SlsaGeneration, provenance step, SLSA attestation, add provenance step" — including both natural user phrasings and the API enum name. Matches the 5 anchor's 'comprehensive coverage of natural terms including synonyms'.

Distinctiveness Conflict Risk

The SLSA-provenance-generation niche is clear and triggers are generation-specific, but within the sibling Harness skill suite (e.g. /enforce-slsa verification, SBOM/SscaOrchestration, artifact signing), phrases like "attest SLSA" and "provenance step" carry minor overlap risk with closely related skills. This fits the 4 anchor ('mostly distinct; minor overlap risk with closely related skills') better than the 5 anchor's 'minimal conflict risk'.
