AI Agent Reliability skill

AI-Agent Reliability

An AI agent that works in a demo and one you can trust in production are different things — the gap is everything that happens when input is messy, the model hallucinates, a tool call goes wrong, or an error fails silently. This maps where your agent can fail and the specific checks that catch each, scaled to the stakes, plus a rollout that earns trust incrementally — so "works sometimes" becomes "works reliably."

What This Skill Produces

• A failure map — where this agent can go wrong: bad/unexpected input, hallucinated output, wrong or malformed tool calls, unhandled edge cases, silent failures, and runaway loops
• The catching checks per failure — input validation, output verification, evals on real cases, schema/format checks on tool calls, human-in-the-loop gates, and monitoring/alerts
• An eval approach — testing on a real set of cases (including the hard ones) so quality is measured, not assumed, and regressions are caught
• Human-in-the-loop placement — where a human must approve, scaled to consequence (irreversible/external actions gated, low-stakes automated)
• A right-sized plan — reliability effort matched to the stakes, not gold-plating a low-risk toy or under-testing a high-risk system
• A trust-building rollout — shadow mode → low-stakes → expand, with monitoring, rather than shipping it everywhere and hoping

Required Inputs

Ask for these if not provided:

• The agent — what it does, what tools/actions it takes, what it touches
• The stakes — what a failure costs (drives how hard to test and gate)
• Where it fails now — the flakiness you've seen (points at the weak spots)
• Your setup — the framework/tools, and whether you can add evals/monitoring

Framework: Map Failures, Catch Each, Earn Trust

1. Enumerate the failure modes. Walk the agent's path — input, reasoning, tool calls, output, actions — and name where each step can break. You can't guard what you haven't named.
2. Attach a check to each. Validation for input, verification for output, schema checks for tool calls, evals for quality, gates for consequential actions — a specific catch per failure.
3. Build real evals. A set of representative and hard cases, scored — so you know it works and catch regressions before users do.
4. Gate by consequence. Irreversible or external actions get a human check; low-stakes steps run free. Match the gate to the cost.
5. Right-size it. Don't over-engineer a low-risk helper or under-test a system that moves money or data — effort follows stakes.
6. Roll out to earn trust. Shadow mode, then low-stakes live, then expand — with monitoring and alerts — so reliability is proven, not assumed.

Output Format

Agent reliability: [what it does] · stakes [level]

Failure map: [bad input · hallucination · wrong tool call · edge cases · silent errors · runaway loops]. Catch each: [failure → the check: validation / verification / schema / eval / human gate / monitor]. Evals: [the real + hard cases to test on, scored]. Human gates: [the consequential actions that need approval]. Right-sized: [effort matched to stakes — where to invest, where not]. Rollout: [shadow → low-stakes → expand, with monitoring].

Quality Checks

• Enumerates failure modes across the agent's whole path
• Attaches a specific check to each failure
• Includes evals on real and hard cases, scored
• Gates consequential actions with a human; automates low-stakes
• Scales effort to stakes; rolls out to build trust incrementally

Anti-Patterns

• Shipping a demo as if it's production-ready.
• No evals — quality assumed, regressions invisible.
• The same trust level for a summary and a money transfer.
• Gold-plating a toy or under-testing a high-stakes system.
• Big-bang launch with no shadow mode or monitoring.

Example Trigger Phrases

• "How do I test my AI agent so I can actually trust it?"
• "My automation works sometimes — how do I make it reliable?"
• "How do I put an AI workflow into production safely?"
• "What checks does my agent need before I let it run on real data?"
• "How do I know my agent won't do something dumb and irreversible?"
