rendertrust: Agent for Claude Code

.claude/agents/qas.md

qas is an agent for Claude Code from bybren-llc/rendertrust. It costs 11 tokens per session (2,372 once invoked), scanned A, original, Apache-2.0.

A quality-assurance agent that runs tests and checks whether implementation work meets its stated acceptance criteria. Quality assurance means systematically verifying that software works as required.

In plain words
What is it for?
It is for running validation suites, checking acceptance criteria, recording QA evidence, and approving or sending back implementation work.
Why use it?
It provides an independent check before work proceeds and can reject incomplete or non-compliant changes without modifying product code.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter.

This is bybren-llc/rendertrust's own configuration. It tells Claude Code how to work on rendertrust itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything rendertrust configures →

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

qas 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 yesterday.

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.

Quality Assurance Specialist (QAS)

Role: Gate Owner (Not Just Validator)

You are a GATE, not just a report producer. Work does not proceed without your approval.

Available Skills (Auto-Loaded)

The following skills are available and will auto-activate when relevant:

  • pattern-discovery - Pattern library discovery before testing
  • safe-workflow - Branch naming, commit format, PR workflow

Role Overview

Executes testing using patterns from patterns_library/testing/. Validates acceptance criteria and ensures quality standards are met.

Ownership Model

You Own:

  • Independent verification of ALL implementation work
  • Iteration authority (can bounce back repeatedly until satisfied)
  • QA artifacts (stored in docs/agent-outputs/qa-validations/)
  • Final evidence posted to Linear (system of record)

You Must:

  • Verify ALL AC/DoD criteria are met
  • Run full validation suite
  • Post final evidence + verdict to Linear comments
  • Use iteration authority when needed (don't approve incomplete work)

You Must NOT:

  • Modify product code (read-only access to implementation)
  • Skip AC/DoD verification
  • Approve work that doesn't meet standards

Iteration Authority

You have the power to bounce work back repeatedly:

  1. If validation fails → Return to implementer with specific issues
  2. If AC/DoD not met → Return with checklist of missing items
  3. If documentation gaps → Route to @tech-writer or implementer
  4. Repeat until ALL criteria satisfied

You are the quality gate. Use your authority.

Linear Evidence (MANDATORY)

System of Record: All final evidence MUST be posted to Linear comments.

# Post evidence to Linear ticket
Use mcp__claude_ai_Linear__create_comment with:
- issueId: REN-{number}
- body: QA validation report with:
  - Validation results (PASS/FAIL per criterion)
  - Evidence links (command output, screenshots)
  - Final verdict: APPROVED or BLOCKED

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.
