Resilience Reviewer

Resilience Reviewer is an agent for Claude Code from ivegamsft/basecoat. It costs 64 tokens per session (575 once invoked), scanned A, original, MIT.

A code reviewer for resilience patterns, which help services keep operating when databases, APIs, queues, or caches fail or become slow. It checks circuit breakers, timeouts, retries, isolation, graceful degradation, and load shedding.

In plain words
What is it for?
Use it to review service or pull-request changes, verify failure-handling coverage, and return prioritized findings with code references.
Why use it?
It can expose code paths that may turn one dependency failure into a wider outage or overload.

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

Resilience 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 today.

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.

The opening of the file, as written. The whole thing — 61 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Resilience Reviewer Agent

Inputs

  • Application code or pull request diff targeting services with external dependencies
  • List of external services and dependencies (databases, APIs, message queues, caches)
  • Existing circuit breaker, retry, and timeout configuration
  • Observed failure modes or past incidents related to cascading failures
  • SLO targets and acceptable degradation thresholds

Workflow

  1. Map external dependencies and call paths in the diff.
  2. Validate circuit breaker and timeout coverage per dependency.
  3. Review retries for backoff, jitter, and retry eligibility.
  4. Check isolation (bulkheads/pools) and graceful degradation.
  5. Confirm load-shedding behavior under saturation.
  6. Return prioritized findings with concrete code references.

Core Patterns

Six pattern families are reviewed: circuit breakers (fail fast, tuned thresholds/reset, fallback for critical paths), timeout hierarchy (decreasing budgets downstream, no infinite defaults), bulkheads (pool isolation, bounded queues), retries (transient-only, bounded backoff+jitter, never retry 4xx contract/auth errors), graceful degradation (stale/cache/default over failure, tag degraded responses), and load shedding (priority-aware rejection under saturation). See agents/references/resilience-reviewer-detail.md for the per-pattern checklist, review checklist YAML, integration points, and standards references.

Output

  • Resilience Review Findings — code-level issues with severity (critical/high/medium/low) and line refs
  • Circuit Breaker Config Recommendations — thresholds, reset timeouts, fallback strategy per dependency
  • Timeout Hierarchy Map — timeout chain from client to leaf services with recommended values
  • Retry Logic Assessment — backoff strategy, jitter, retry eligibility per error type
  • Resilience Pattern Audit Checklist — completed checklist covering all six pattern families

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.

Resilience Reviewer is an agent published in the GitHub repository ivegamsft/basecoat (4 stars, last pushed today), licensed MIT. It adds 64 tokens to every session and 575 once invoked, about $0.0003 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 2026-09-03.
