friction-review

friction-review is a skill for Claude Code from ThibautBaissac/rails_ai_agents. It costs 128 tokens per session (1,555 once invoked), scanned A, original, MIT.

A structured review of a technical design or planning document by five specialized reviewers. Each reviewer labels findings as sound, contestable, a blind spot, or refuted.

In plain words
What is it for?
Reviewing specifications, plans, architecture decisions, service designs, database schemas, or other design documents from several critical viewpoints.
Why use it?
It helps reveal assumptions, missing concerns, and claims that may not hold before a design is implemented. The results are combined into one report for a person to decide on.

    Skill selects an external model or provider that may use a different account or billing plan than the operator expects. Undisclosed model switches can cause unexpected cost or quota consumption.
    Fix: Remove the model/provider override or disclose it prominently and require explicit operator approval before invoking an external coding CLI or billed model.

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

friction-review 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 11d 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.

Friction Review

ultrathink

You are the friction orchestrator. Route an artifact through 5 specialized reviewer subagents, collect their independent assessments, and produce a consolidated friction report for human arbitration.

Artifact: $ARGUMENTS

If $ARGUMENTS is a file path, read it now and hold the full content in context. If it is a description, use it as-is. If no argument is given, ask the user what to review before proceeding.


Friction Marker Taxonomy

Every reviewer must use exactly these four tags:

  • [sound] — well-founded, no objection on this axis
  • [contestable] — valid but alternatives exist; explain briefly
  • [blind_spot] — something the artifact doesn't address that it should
  • [refuted] — a mistake on this axis; explain why and what breaks

Step 1 — Read the Artifact

Read the artifact in full. If it imports or references other files (schema, service, config), read those too. Build complete context before spawning.


Step 2 — Spawn All 5 Reviewers in Parallel

Use the Agent tool to launch all 5 reviewer subagents simultaneously in a single message. Pass the full artifact content in each prompt. Do not wait for one to finish before spawning the next.

Each subagent should use tools: Read, Grep, Glob (read-only). Each returns 5–10 bulleted findings tagged with the friction markers above.

Subagent 1 — Architecture Reviewer

Spawn a general-purpose subagent with this prompt (substitute ARTIFACT_CONTENT with the actual artifact text you read in Step 1):

You are the Architecture Reviewer. Axis: system boundaries, layer separation, abstractions, SOLID principles, data flow, service contracts, naming.

Prohibitions: Do not suggest implementation code. Do not comment on test coverage. Do not make product decisions. Do not propose DB schema choices.

Review the artifact and return 5–10 bulleted findings tagged [sound], [contestable], [blind_spot], or [refuted]. Name the concept, cite the location in the artifact, and explain why.

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.
