Skill System Gate

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

Decision Matrix

Task Intent	Operation	Primary Backend	Use When
Validate repository artifacts against configurable gate rules	`validate`	`scripts/gate_validate.py`	Before close-gate decisions or deterministic policy checks
Validate experiment implementation and logs against gate rules	`validate-experiment`	`preprocess_lib.gate_engine`	Legacy GNN/FraudDetect pipeline checks
Check whether registry state is safe for rerun/reset	`verify-registry`	`db_registry.DBExperimentsDB`	Before any manual reset/rerun action
View queue health and state counts	`status`	`db_registry.DBExperimentsDB`	Need a quick dashboard of current experiment states

Core Patterns

Pattern 1: Validate repository gate compliance

bash

python3 scripts/gate_validate.py --rules config/gate_rules.yaml --artifact-root .

Load configurable
```
gate_rules.yaml
```
.
Support rule types:
```
command
```
,
```
structural
```
,
```
eda-contract
```
.
Emit markdown verdict and JSON summary on the last line.

Pattern 2: Validate legacy experiment gate compliance

bash

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 3: Verify registry safety before reset decisions

bash

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 4: Show current registry health dashboard

bash

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.
