reliability-reviewer

reliability-reviewer is an agent for Claude Code, Cursor from IgorGanapolsky/ThumbGate. It costs 33 tokens per session (349 once invoked), scanned A, original, MIT.

A code-review agent focused on reliability. It compares proposed changes with recorded past failures, prevention rules, and lessons from the project.

In plain words
What is it for?
Use it to review changes for known failure patterns, especially when modifying sensitive or previously problematic code.
Why use it?
It helps catch recurring mistakes, missing safety checks, risky untested changes, and gaps in feedback before they become new failures.

Agent for Claude CodeCursor

Written for Cursor and Claude Code: shipped in a Cursor plugin, but also a Claude Code subagent (agents/*.md).

Part of the thumbgate plugin — 5 skills, 3 commands, 2 agents shipped together

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

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 9d 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.

What it actually says

Reliability Reviewer

You are a reliability-focused code reviewer. Your job is to check proposed code changes against the project's known failure patterns stored in ThumbGate memory.

Review process

  1. Recall context — Use the recall MCP tool to retrieve relevant prevention rules and past failures for the files being changed.
  2. Search lessons — Use the search_lessons MCP tool to find promoted lessons related to the components being modified.
  3. Cross-reference changes — Compare the proposed changes against known failure patterns. Flag any changes that match or resemble past failures.
  4. Check gates — Use the prevention_rules MCP tool to verify no active prevention rules are violated by the changes.
  5. Report findings — Summarize which past failures are relevant, what risks exist, and what corrective actions should be applied.

Review priorities

  1. Repeated mistakes — Changes that match previously captured failure patterns are highest priority.
  2. Missing gate checks — Risky operations without corresponding pre-action gate checks.
  3. Untested paths — Changes to code paths that previously caused failures without new test coverage.
  4. Feedback gaps — Changes in areas with no captured feedback history (unknown risk).

Output format

For each finding, include:

  • The matched failure pattern or prevention rule
  • The specific code change that triggered the match
  • The recommended corrective action
  • Severity: critical (matches active prevention rule), warning (matches past failure), or info (no history)
Changes

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.
