Prompt Reliability Engine

Use this skill to make prompts, skills, and workflows production-grade through diagnosis, repair, stress testing, constraints, output locking, workflow design, audit, pruning, and self-improvement.

Invocation Triggers

• Weak, failing, inconsistent, or under-specified prompt.
• New skill, command, workflow, or reusable instruction set.
• Prompt outputs drift in format, tone, length, naming, or structure.
• User asks whether a prompt is production-ready.
• User wants stricter wording, test cases, edge-case coverage, or a feedback loop.

Do not use for simple one-shot questions or code-only tasks with no prompt/instruction design component.

Core Workflow

1. Identify the target: prompt, skill, command, workflow, or output contract.
2. Select one or more modes from the routing table.
3. Diagnose before repairing.
4. Convert vague goals into observable constraints.
5. Stress-test important artifacts with normal, minimal, ambiguous, adversarial, and off-scope inputs.
6. Lock output shape when consistency matters.
7. Report evidence, risks, and remaining failure modes.

Mode Routing

Mode	Use When	Required Output
1 Failure Repair	Prompt is broken or underperforming	Diagnosis, root causes, fixed prompt, retest matrix
2 Skill Builder	Build a reusable prompt/skill/workflow	Goal, risks, production artifact, safeguards, tests
3 Stress-Test	Determine breakability	Adversarial input set, failure log, severity, score
4 Constraint Engineer	Instructions are vague	Before/after constraints and consistency score
5 Output Lock	Outputs drift	Fixed sections, order, limits, allowed/forbidden content
6 Workflow Architect	One prompt should become a pipeline	Phases, handoff formats, checkpoints
7 Production Audit	Decide readiness	5-dimension scorecard and priority fixes
8 Language Pruning	Wording is soft or bloated	Flagged phrases, tightened version, word-count delta
9 Self-Improving Skill	Artifact will be reused	Failure log schema and improvement cycle

See modes.md for full mode procedures.

Reliability Rules

• Preserve original business goal, scope, audience, and required tone unless those are the problem.
• Fix root causes, not cosmetic symptoms.
• Make constraints measurable.
• Name output sections and order when format stability matters.
• Expose weaknesses before proposing fixes in stress-test mode.
• Keep uncertainty when truthfully required; remove hedging that weakens instructions.
• Apply existing anti-slop and public-safety rules from the active repo policy.

Mode Selection

• Broken prompt: Failure Repair -> Constraint Engineer -> Output Lock -> Audit.
• Build from scratch: Skill Builder -> Stress-Test -> Output Lock -> Audit.
• "Is this good enough?": Stress-Test -> Audit.
• Inconsistent outputs: Output Lock -> Constraint Engineer -> Language Pruning.
• Reusable system: Workflow Architect -> Self-Improving Skill.
• Stricter wording: Language Pruning.

If unspecified, infer the mode and state it briefly.

Output Expectations

• Mode selected and why.
• Diagnosis before rewrite.
• Revised prompt/skill/workflow only when repair/build is requested.
• Test or stress matrix for important systems.
• Reliability score or readiness score when auditing.
• Remaining risks and next recommended fix.
