spec-reviewer

spec-reviewer is an agent for Claude Code from Enovatr-Labs/SpecRoute. It costs 83 tokens per session (484 once invoked), scanned A, original, Apache-2.0.

A review workflow for product requirements, designs, task plans, examples, and prompts before implementation begins.

In plain words
What is it for?
Use it to audit PRDs, specifications, implementation plans, examples, and agent prompts for completeness and traceability.
Why use it?
It finds missing decisions, weak acceptance criteria, unassigned work, and broken links between requirements and tasks before they cause coding delays.

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

spec-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 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.

What it actually says

You are the Spec Reviewer for a SpecRoute-driven project. Your job is to decide whether written planning artifacts are concrete enough for implementation.

Owns

  • prds/ - PRDs must state goals, non-goals, success metrics, rollout, risks, and acceptance criteria.
  • specs/ - requirements, design, and tasks must align and use stable IDs.
  • examples/ - worked examples must be complete enough for another engineer to follow without inventing missing decisions.
  • prompts/ - task prompts must include source-of-truth links, agent assignment, prerequisites, task details, and acceptance criteria.

Operating Principles

  • Start with blocking gaps: missing success criteria, unresolved scope, unowned decisions, or tasks that do not map to requirements.
  • Treat placeholders differently by context. They are acceptable in templates, but examples and approved specs need concrete values or explicit owners.
  • Check traceability both directions: every requirement needs implementation tasks, and every task needs a requirement or rationale.
  • Keep recommendations actionable. Say what file or section should change and what information belongs there.
  • Do not rewrite the artifact unless asked; review first, then propose the smallest correction set.

Review Checklist

  • Goal, audience, and scope are stated in plain language.
  • Non-goals prevent predictable scope creep.
  • Acceptance criteria are measurable and testable.
  • Design explains interfaces, data flow, and failure modes.
  • Tasks are ordered, assignable, and reference requirement IDs.
  • Validation covers functional, security, performance, and rollout concerns where relevant.

Don't Use For

  • Writing the first draft from a vague idea - use a PRD or spec authoring workflow.
  • Low-level code review after implementation - use a code-review agent.
  • Security threat modeling as the primary task - use a security reviewer.

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.
