kingfisher

Find, live-validate, map the blast radius of, and revoke leaked secrets with Kingfisher (MongoDB) — across a local repo, Git history, a GitHub/GitLab/Bitbucket org, S3/GCS, Docker images, Slack, Jira, Confluence, Teams, or Postman. Covers local CLI scanning, direct validate/revoke without a scan, baseline management (track only new secrets), kingfisher.yaml policy, CI diff-scan gates, and pre-commit/Husky hooks. Use when asked to "scan for secrets", "is this key still live", "what can this credential reach", "revoke this token", "did we leak a secret", or "block new secrets in CI". Pattern-only secret scan bundled with a CVE pass → /platform-skills:trivy. Secrets-context safety in workflow YAML → /platform-skills:zizmor. Storing/rotating secrets inside the cluster → /platform-skills:secrets.

Quality

Content

66%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A well-engineered, safety-conscious skill body with executable commands, explicit destructive-operation gates, and validation feedback loops — but it is built around a references/kingfisher.md file that is absent from the bundle, leaving its CI/bootstrap detail dead-linked, and it restates the same routing and outcome-distinction policies three to four times across sections.

Suggestions

Ship references/kingfisher.md in the bundle (or inline the critical content it uniquely provides — CI templates, bootstrap pin, kingfisher.yaml schema), since the body instructs reading it 'before responding' and cites it ~10 times.

Deduplicate the ownership/routing information: the trivy/zizmor/secrets boundary is stated in the ownership table, Layer 1 menu, intent-classification table, and cross-references — keep one authoritative table and trim the rest to pointers.

State the assumed-vs-verified_active distinction once (e.g., in scan's report format) and reference it elsewhere, rather than re-explaining it in triage, Layer 3, and both the Never and Always lists.

DimensionReasoningScore

Conciseness

The body is dense and assumes Claude's competence (no explanation of what secret scanning is), but the same policies are restated repeatedly: the trivy/Kingfisher boundary appears in the ownership table, Layer 1, the intent-classification table, and the cross-references; the assumed-vs-verified_active distinction is spelled out in scan, triage, Layer 3, and both Never/Always lists; the revoke three-part gate appears three times. This goes beyond 'minor instances that could be trimmed' (anchor 4) into territory that needs tightening, but it is not padded with concepts Claude already knows (anchor 2).

3 / 5

Actionability

Mostly executable: copy-paste commands for scan/validate/revoke/config/baseline, a complete pre-commit YAML with full args, and concrete report orderings. It falls short of anchor 5 because several modes defer their substance to 'references/kingfisher.md' — the CI mode's actual templates ('Copy the matching template from references/kingfisher.md → CI integration') and the bootstrap pin — and that file does not exist in the bundle, so those sections are not actionable as shipped. Still clearly above anchor 3, which would mean pseudocode or missing key details in the inline guidance itself.

4 / 5

Workflow Clarity

Clear sequences with explicit validation checkpoints and feedback loops: the scan report order (verdict → counts by outcome → findings → history note → next step), the triage decision tree, and especially revoke — a required three-part gate (validated live, owner identified, replacement ready) plus a post-revoke re-validate step to confirm the provider actually applied the revocation. The destructive-operation cap (score ≤3 without validation) does not apply because validation is present and thorough.

5 / 5

Progressive Disclosure

The body's structure is nominally good (clear sections, one-level-deep reference model, scripts/pre-commit.sh correctly referenced and present), but the primary reference 'references/kingfisher.md' — instructed to be read 'before responding' and cited ~10 times for the CLI surface, config schema, CI templates, and bootstrap — is missing from the bundle entirely. Judged against the actual bundle structure as the guidelines require, the promised detail layer is a dangling pointer, breaking the skill's navigation. Not 3: the problem is not that references are poorly signaled but that the central reference does not exist; not 1 because the body itself is well organized and the scripts reference resolves correctly.

Description

100%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

An exemplary skill description: comprehensive concrete capabilities, natural trigger phrases with synonym coverage, an explicit 'Use when' clause, and explicit boundary routing to adjacent skills. It is dense but every clause carries information — no fluff or over-claims.

DimensionReasoningScore

Specificity

The description enumerates multiple concrete actions ('Find, live-validate, map the blast radius of, and revoke leaked secrets') plus concrete coverage areas (baseline management, kingfisher.yaml policy, CI diff-scan gates, pre-commit/Husky hooks) and enumerated targets (GitHub/GitLab/Bitbucket org, S3/GCS, Docker images, Slack, Jira, Confluence, Teams, Postman). Comprehensive and specific with no vague filler; not below 5 because no concrete capability is missing, and not above because 5 is the scale maximum.

5 / 5

Completeness

Explicitly answers both questions: 'what' via the concrete capability list and 'when' via a literal 'Use when asked to' clause with concrete trigger phrases. Matches the anchor example for 5 exactly in structure; a 4 would mean the 'when' was present but less explicit, which it is not.

5 / 5

Trigger Term Quality

Includes natural quoted trigger phrases users would actually say — 'scan for secrets', 'is this key still live', 'what can this credential reach', 'revoke this token', 'did we leak a secret', 'block new secrets in CI' — covering synonyms across secret/key/credential/token vocabulary. Matches the comprehensive-synonyms anchor; a 4 would require 'a few natural terms missing', which is not the case here.

5 / 5

Distinctiveness Conflict Risk

Occupies a clear niche (live validation, blast-radius mapping, revocation of leaked secrets) and actively disambiguates against adjacent skills ('Pattern-only secret scan bundled with a CVE pass → /platform-skills:trivy', 'Secrets-context safety in workflow YAML → /platform-skills:zizmor', 'Storing/rotating secrets inside the cluster → /platform-skills:secrets'), minimizing wrong-skill triggering. Not 4: the boundary routing is explicit rather than leaving minor overlap risk.
