Your agent passed every test.It still fails 27% of the time.
Per-step metrics look fine while the end-to-end workflow quietly fails, drift creeps in between releases, and postmortems close with the real fix still open. This bundle is the three tools that run the whole reliability loop: evaluate the release, watch for drift, and close the loop when it breaks. Three RedHub tools, one standard, $58 less than buying them separately.
Every step works. The workflow doesn't.
Agent reliability fails in the gaps between the numbers you watch. A chain of steps that each pass 85% of the time completes end-to-end just 27% of the time — and no single-step dashboard shows it. Releases drift between versions while every component still looks green. And when an incident finally lands, the postmortem gets written, filed, and closed with the critical fix still open.
Each of those is a different stage of the same problem, and each needs its own discipline. This bundle puts all three on one reliability surface — so "are our agents actually dependable, and do we prove it when they're not?" becomes a question you can answer with evidence, not hope.
Three tools. One reliability loop.
Each tool is the same full product sold on its own page — engine, workbook, and worked example included, nothing trimmed for the bundle. Click any card to see the individual product page.
Agent Reliability Harness
Evaluate agents at the trajectory level — tool choice, argument validity, step efficiency, cost, and policy — across six deterministic evaluators, and gate CI on a ship / hold / fix verdict before a release ever reaches production.
View productAI Agent Quiet-Failure & Drift Monitor Kit
Reveal each multi-step agent's true compounded success rate (an 8-step chain at 85% per step succeeds just 27% of the time), catch quiet drift between releases, and verdict every workflow STABLE / SHORTEN / CHECKPOINT.
View productAI Incident Postmortem & Readiness Gate
When an agent does break, grade the blameless postmortem across six sections — CLEARED TO CLOSE / FINISH ACTIONS / NOT CLOSEABLE — with an open-critical-action gate that refuses to close the incident while a single critical fix is still open.

Evaluate, monitor, and close the loop.
Evaluate before you ship
The Reliability Harness scores an agent's whole trajectory — not just the final answer — and fails CI when tool calls, arguments, cost, or policy drift out of bounds. Releases earn their way to production.
Watch it in the wild
The Drift Monitor catches what testing can't: the compounding quiet failures across a multi-step chain, and the slow drift between releases where each step still looks fine but the end-to-end rate slides.
Close the loop when it breaks
When an incident happens anyway, the Postmortem Gate makes sure the writeup is real and the critical fixes actually land — no incident closes with an open critical action, no matter how polished the doc.
Test alone ships an agent that drifts; monitor alone catches failures you never learn from. Together these three run the whole loop — evaluate, watch, and prove the fix landed.
Evidence you can defend, not a green dashboard you'd hope is right.
A reliability tool is only worth running if it refuses to round a real failure away. Every tool in this stack holds the same RedHub standard — surface the risk, name exactly where it is, and end in a decision you can act on this week.
Trajectory, not just output
A right answer reached the wrong way is still a reliability risk. Each tool judges how the agent got there — the steps, the drift, the remediation — not just whether the last token looked correct.
The gate beats the average
A healthy per-step rate hides a 27% chain; a thorough writeup hides an open critical fix. Each tool refuses to let a real failure round away behind a comfortable mean — the exception is the signal.
Deterministic decision aids
Same inputs, same verdict, every time — offline, nothing uploaded. Each tool ends in a call you act on this week: hold the release, shorten the chain, finish the action. Working aids, not a live integration or a guarantee.
For everyone who owns the promise that the agent works.
Teams running agents in production
When 'it worked in testing' turns into a confused customer, you need the full loop — evaluate the release, watch for drift, and run a postmortem that actually closes the gap. This is that loop in one purchase.
Platform & reliability engineers
Gate CI on agent behavior, instrument the compounding-failure math your dashboards miss, and hold incident reviews to a real readiness bar. Three reads on the same reliability surface, one standard.
Founders who own the uptime promise
You told customers the agent is dependable. These three keep that promise honest — catching the quiet failure before they do, and proving the fix landed after.

Want the developer-grade CI stack instead? The AI Reliability Bundle packages the four LLM dev tools that gate your build pipeline. See all RedHub bundles for the full set.
Answers before you ask.
Three RedHub tools that keep production AI agents reliable end-to-end: the Agent Reliability Harness ($149), the AI Agent Quiet-Failure & Drift Monitor Kit ($49), and the AI Incident Postmortem & Readiness Gate ($79). Bought separately they total $277; the bundle is $219, so you save $58.
Because agent reliability is a lifecycle, and each tool owns one stage. The Reliability Harness evaluates a release before it ships, gating CI on trajectory-level behavior. The Drift Monitor watches it in production, surfacing the compounding quiet failures and slow drift that per-step metrics hide. The Postmortem Gate closes the loop when something breaks, refusing to call an incident done while a critical fix is still open. Evaluate, monitor, learn — the full reliability operations loop in one pass.
Different altitude. The AI Reliability Bundle is the developer-grade CI stack — four LLM dev tools (RAG Retrieval Grader, Prompt Regression Lab, Prompt Injection Red Team Kit, and the Agent Reliability Harness) that gate your build pipeline. This Operations bundle is the production lifecycle: it pairs the same Agent Reliability Harness with the Drift Monitor and the Incident Postmortem Gate, so you don't just pass CI — you watch reliability in the wild and close the loop when it slips. The Harness is the hinge both share; pick this set if your concern is running agents reliably, not just shipping them.
Yes. The bundle includes the full, individual products exactly as sold on their own pages — each one's engine, workbook, and worked example included. Nothing is trimmed for the bundle; the discount is the only difference.
No live integration. You bring the data — your agent's trajectory traces, step counts and per-step reliability, your incident writeup — and the engines do the rest. They're deterministic and offline, so they run anywhere in CI or locally and nothing is uploaded. Decision aids for the reliability calls, not a guarantee of any uptime number.
30-day no-questions refund on the bundle. Run the harness against a real agent and the drift monitor against one multi-step workflow this week. If the set doesn't surface a reliability risk you can act on, email us and we refund.
Evaluate it, watch it,
prove the fix landed.
Gate the release, catch the drift, and close every incident for real — the full reliability loop for production agents. $58 less than buying them separately.
