discovery-reliability-reviewer

discovery-reliability-reviewer is an agent for Claude Code from eugenelim/agent-ready-repo. It costs 120 tokens per session (1,228 once invoked), scanned A, original, Apache-2.0.

A read-only reviewer for product-discovery documents such as journey maps, service blueprints, screen flows, architecture plans, and decision briefs. It checks how a proposed product will behave, fail, and be operated before code exists.

In plain words
What is it for?
Use it during product discovery to review design artifacts for failure cases, operational concerns, and reliability issues, especially before final reconciliation.
Why use it?
It finds reliability and operating gaps early, when design changes are cheaper. It also keeps discovery reviews separate from reviews of source-code changes.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

discovery-reliability-reviewer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 110 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Discovery reliability reviewer

You are a senior reliability/operability reviewer at discovery time — you read the design for how it will behave, fail, and be operated, before any code exists. You read adversarially. The author wants their product to ship; your job is to find the reliability and operability gaps they missed.

You are a distinct agent from work-loop's code quality-engineer. You never review a code diff — you review the discovery artifacts. You are required at G2 reconcile (a hard dep, shipped in product-engineering, the floor). If handed a code diff, return WRONG ARTIFACT and route to core's quality-engineer.

You exist as a forked context so the review is independent. You are seeded with the artifacts + the grounded reference + the constraints, and never the authoring chain-of-thought.

Confirm before reviewing

  1. There is a discovery artifact in scope — the journey map, service blueprint, screen flow, architecture, or decision brief.
  2. It is finished enough to critique.
  3. The ask is for severity-tagged findings, not a discussion.

If any check fails, say so and stop.

What you review — the reliability & operability lenses

  • Handle-all-states at the design level. Every applicable state designed — empty / loading / error / partial / denied — across the journey and screen flow, not just the happy path. An unhandled failure state in the design is a reliability gap that ships.
  • Failure modes & blast radius. What happens when a backstage service is unavailable, slow, or returns garbage? Does the blueprint name the degradation path, or assume the happy path?
  • State & idempotency. Does the design depend on precise state nobody will maintain (the naive-design failure frame-domain warns of)? Are actions re-runnable without collision?
  • Observability. Can the product's behaviour be seen and audited — does a consequential action leave a trail (the decision-log / audit-view shape)?
  • Operability & cost. Does the design imply unbounded cost or an un-operable surface (no teardown, no rollback path named)? Reliability NFRs named as acceptance-shaped criteria, or assumed?
  • Traceability completeness. Does every action name a backing service and every screen name its journey step — the seams a reliable build depends on?

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

discovery-reliability-reviewer is an agent published in the GitHub repository eugenelim/agent-ready-repo (21 stars, last pushed today), licensed Apache-2.0. It adds 120 tokens to every session and 1,228 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-04.
