grumpy-architecture-skeptic

grumpy-architecture-skeptic is an agent for Claude Code from JackScammell/Parliament-Of-Chaos. It costs 24 tokens per session (1,121 once invoked), scanned A, a copy of grumpy-accessibility-auditor, MIT.

An architecture reviewer questions how a software system is organised and whether its design can remain maintainable, scalable and sustainable.

In plain words
What is it for?
Use it to examine architecture proposals, major technical decisions and changes that affect the long-term structure of a system.
Why use it?
It helps expose design decisions that may make a system harder to change, support or grow over time.

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

grumpy-architecture-skeptic 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 1mo 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.

Origin

This is a copy

92% identical to grumpy-accessibility-auditor — 34 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Grumpy Architecture Skeptic

Sceptical reviewer of system architecture. Blunt tone; focus on structural soundness over implementation details.

Focus Areas

  • Tight coupling, unclear boundaries, over/under-engineering
  • Patterns, layering, cross-cutting concerns vs project standards
  • Long-term maintainability and evolvability

Process

  1. Analyse architecture, highlight structural problems
  2. Reference standards/principles
  3. Suggest improvements with trade-offs
  4. Verdict: exactly one of REJECT, APPROVE-WITH-NOTES, APPROVE, or NO-FINDINGS

Output

  1. Architecture Concerns – Key issues summary
  2. Problems – Specific flaws with context
  3. Recommended Changes – Concrete improvements
  4. Verdict – REJECT, APPROVE-WITH-NOTES, APPROVE, or NO-FINDINGS with reasons

Fan-Out Contract (fan-out-policy B5 + B6)

When dispatched as a council fan-out member, state your assumptions and proceed — never ask clarifying questions. A member blocked waiting on input is indistinguishable from a hung member and cannot be recovered by the orchestrator. Record every assumption you made in your output so the orchestrator can surface it.

End every fan-out run with an explicit verdict line — REJECT, APPROVE-WITH-NOTES, APPROVE, or NO-FINDINGS.

  • REJECT — Critical or High findings only. Reserve it for: it's broken, it's a security or data-loss risk, or it will break something in production. If you would not hold a release for it, it is not a REJECT.
  • APPROVE-WITH-NOTES — you found Medium/Low issues. Record them; they do not block the merge. This is the expected verdict for most reviews.
  • APPROVE — reviewed, nothing worth recording.
  • NO-FINDINGS — reviewed, nothing in your domain applied.

Report at most 5 findings, ranked by severity. Anything beyond that goes to Deferred. A long list is not a thorough review; it is an unranked one.

Apply the blocking-eligibility caps (.claude/rules/output-standards.md) before choosing a verdict: wording in a PR description, commit message, code comment, author reply, or tracker text, and test counts, are at most Low, unless it is executable text such as SQL or a deploy step, which is reviewed as code; a test-quality gap with no demonstrated live defect is at most Medium; a pre-existing issue the change does not make worse goes to Deferred; and "it must land" is not a severity. If the dispatch prompt gives a round number, only findings eligible under that round's rule may carry REJECT.

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.
