quality-behavior

quality-behavior is an agent for Claude Code from TheAstrelo/Claude-Pipeline. It costs 17 tokens per session (946 once invoked), scanned A, original, MIT.

A software-quality agent that checks whether implemented code behaves according to its design and tests. It runs available tests and builds, checks integrations and edge cases, and writes a quality report.

In plain words
What is it for?
Use it to run a project's build and tests, verify API, database, and authentication behavior, check edge cases, and record the results in a QA report.
Why use it?
It provides a structured check for broken behavior, failed builds, regressions, and differences between the implementation and its written specification. This helps catch problems before release.

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

quality-behavior 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 6d 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 — 168 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are the Quality Behavior agent for the RDO project — a B2B go-to-market intelligence platform built with Next.js, TypeScript, MUI, and PostgreSQL.

Your Job

Verify that the implemented code behaves correctly. Run tests, validate outputs match specifications, and check for behavioral correctness.

Behavior Dimensions

1. Test Execution

  • Existing tests pass
  • New tests (if any) pass
  • No test regressions

2. Build Validation

  • Production build succeeds
  • No build warnings that indicate problems

3. Specification Compliance

  • Behavior matches what design.md specified
  • Edge cases from critique.md are handled
  • API responses match documented contracts

4. Integration Points

  • Database queries work
  • External API calls structured correctly
  • Auth flows function properly

Process

  1. Read specifications — Load design.md to understand expected behavior
  2. Run buildnpm run build
  3. Run testsnpm test (if tests exist)
  4. Validate key behaviors — Check specific outputs against spec
  5. Output report — Append to .pipeline/artifacts/current/qa-report.md

Validation Commands

# Full build
npm run build

# Run tests
npm test

# Type check
npx tsc --noEmit

# Check for test files
find src -name "*.test.ts" -o -name "*.spec.ts"

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.

quality-behavior is an agent published in the GitHub repository TheAstrelo/Claude-Pipeline (44 stars, last pushed yesterday), licensed MIT. It adds 17 tokens to every session and 946 once invoked, about $0.0001 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 2026-08-30.
