bhangeef16 Skill Review DiffUse when a delivery run dispatches a diff-review action: the correctness/simplification/convention pass (diff_review, code-reviewer persona) or the security-pattern pass (security_pattern_review, security-reviewer persona) over an implementation diff. One shared procedure — findings tied to specific files/lines with concrete failure or exploit scenarios, or an explicit no-findings record — parameterized by the action id passed as the first skill argument and the persona dispatched. Replaces the retired diff-review and security-pattern-review skills.

bhangeef16 Skill Review EvidenceUse when a delivery run dispatches a verification-stretch evidence-judging action: test evidence (test_evidence_review, qa-engineer), security evidence (security_evidence_review, security-reviewer), runtime evidence (runtime_evidence_review, devops-ops), or documentation evidence (documentation_evidence_review, documentation-steward). One shared procedure — judge recorded evidence against what it claims, prove existing work without expanding scope, record residual findings explicitly even when empty — parameterized by the action id passed as the first skill argument and the persona dispatched. Replaces the retired test-evidence-review, security-evidence-review, runtime-evidence-review, and documentation-evidence-review skills.

mickzijdel Bundle Repo ReviewWhole-repository review/audit of an existing or inherited codebase. Use when the user says "review this repository", "audit this codebase", "do a full code review of the repo", "what's wrong with this app", "I just inherited this project", or asks for a multi-axis sweep (e.g. "review for 1. performance 2. code smells 3. structure"). NOT for reviewing a single diff/PR (use the /code-review command) or a one-file change.
-
mickzijdel Bundle Dev Env SetupAudit a repo against an opinionated dev-environment standard (mise pinning tools, an hk pre-commit hook running linters/tests + gitleaks, a GitHub Actions workflow that mirrors those checks, and project docs — README.md + CLAUDE.md recording pinned package versions) and set it up or upgrade it. Use when a repo is missing the standard setup, when the dev-env-reminder hook flags a gap, when the user mentions hk/mise/gitleaks/"my dev setup", when starting a new repo, or to backfill every standard-tracking repo after a version bump (fleet mode). Tracks a standard version via DEV_ENV_VERSION in mise.toml and upgrades behind repos using references/upgrade-guide.md.
-
mickzijdel Bundle Github ActionsWrite, review, and harden GitHub Actions workflows against supply-chain attacks, and bump a whole fleet of repos' action pins to the latest versions. Use when writing or editing a workflow YAML (.github/workflows/*.yml, ci.yml), when asked to review a CI workflow or audit GitHub Actions security, when the ci-action-ref-reminder hook fires, or when the user wants to "bump my actions", "update the fleet", "pin actions to SHAs", run zizmor, or close supply-chain / pull_request_target / script-injection / GITHUB_TOKEN-permissions gaps. Pairs with references/security-checklist.md (the full checklist) and dev-env-setup's CI templates.
-

-
mrilikecoding Skill Citation AuditComprehensive audit of a paper's citations. Verifies every reference exists, checks claim-source alignment, identifies missing seminal works, and analyzes citation patterns for bias. Use when asked to check references, verify citations, or audit a bibliography.
-
mrilikecoding Bundle Codebase AuditComprehensive multi-lens codebase architectural analysis with pedagogical stewardship framing. Evaluates architecture, patterns, code health, test quality, documentation accuracy, and system invariants. Use when approaching a new or poorly-understood codebase, or when you need to understand a codebase's actual architecture vs. its intended architecture.
-
poorvith-mp Bundle Exam StrategyPace the paper, triage questions by marks-per-minute, exploit the marking scheme, and decide when to guess. Use when mastering test pacing, elimination tactics, or time allocation.

yesterday-ai Bundle Audit SkillsAudit this repo's skills + plugins on three axes -- (1) leaks of personal info or Yesterday-internal references in user-facing artifacts, (2) catalog consistency (folder/name/dep/install-target alignment), (3) plugin-spec compliance (Claude Code + Cursor manifest schemas, layout rules). Reports findings as a triage list; does not auto-fix. Use before publishing, before merging skill PRs, or as a periodic hygiene pass.

epam Skill Security Monitor TriagerSkeptical second-opinion review of proactive-security-monitor output. For each OSV advisory it re-verifies version-match and reachability against this repo's actual code, and re-judges the news pass's RELEVANT/TANGENTIAL/IGNORE calls. Emits per-item verdicts (CONFIRMED / OVERSTATED / FALSE_POSITIVE / NEEDS_REVIEW). Use as the triage half of the proactive-security-monitor → security-monitor-triager chain.
-
epam Bundle Proactive Security MonitorProactive supply-chain watch for this repo. Resolves the npm SBOM and batch-queries OSV.dev for freshly-modified advisories (committed fetch.sh), then runs an industry-news pass (CISA KEV, OpenSSF, GitHub Security Lab, Socket, The Hacker News) filtered to this project's stack, and emits both as one findings set for the downstream triager. Use as the daily/scheduled producer half of the proactive-security-monitor → security-monitor-triager chain.
