Skill System Gate

Enforce a fail-closed gate before experiment registration and provide read-only registry safety/status checks.

Decision Matrix

Core Patterns

Pattern 1: Validate experiment gate compliance

scripts/validate_exp.sh <exp_name> [phase_root]

• Load gate_bank.json rules.
• Run all rule classes (source_contains, source_not_contains, stderr_scan, file_exists, file_min_size).
• Emit markdown verdict and JSON summary on the last line.

Pattern 2: Verify registry safety before reset decisions

scripts/check_registry.sh <exp_name> [phase_root]

• Read registry entry for the experiment.
• Block reset recommendation for RUNNING experiments.
• Return status details and safe_to_reset decision JSON.

Pattern 3: Show current registry health dashboard

scripts/status.sh [phase_root]

• Aggregate counts across active/completed sets.
• Show running experiments and execution location.
• Return compact JSON counters on the last line.

Guidelines

• Always treat validation as fail-closed: any error-severity rule violation means gate failure.
• Always run validate-experiment before registry-facing actions.
• Never modify experiment source/config files during checks.
• Never execute reset/rerun from this skill; only report recommendations.
• Never override RUNNING experiments as safe to reset.
• Keep all operations read-only with respect to registry and experiment artifacts.
