What H-Diagnose does

H-Diagnose identifies the most likely cause of a concrete failure by stabilizing the signal and testing multiple rival explanations in parallel read-only probes. Use it when symptoms are observable but the root cause is unclear, and preserve losing hypotheses for fallback or replay.

H-Diagnose is cataloged under Quality on DirSkills. H-Diagnose comes from a repository tagged ai-agents, ai-coding, anthropic, claude and claude-code.

Decision Verification

Decision Verification checks whether a recorded DecisionRecord still holds by running baseline vs measure evidence loops and drift detection. Use it when a shipped decision needs a post-implementation reality-check before further work relies on it.

H Explore

H Explore generates 3-5 genuinely distinct candidate approaches for a current question, keeping the weakest link of each visible. Use it when alternatives are needed or a favored approach is prematurely closing the search.

H Status

H Status reports read-only project memory and coverage from a current code index, including active problems, decisions, notes, evidence freshness, drift, and file-link gaps. Use it for project status, session resumption, or answering what is decision-linked, uncovered, or needs attention.

H Verify

H Verify compares recorded DecisionRecords or claims against current code, tests, measurements, or incidents to surface weakened, refuted, stale, or drifted claims. Use it when design-time claims need runtime evidence before relying on them.

H-Commission

H-Commission creates a WorkCommission grant from an active DecisionRecord only when manually invoked by an operator. It verifies source decision status and freshness, derives execution scope, snapshots the autonomy envelope, and stops before any execution.

H-Commission

H-Commission creates bounded execution authority from an explicit operator grant and never auto-triggers or infers approval from prompt text or tool schemas. Use it when an agent needs a manual human gate before executing scoped actions.
