Evaluate

Evaluate is an agent for Claude Code from dean0x/devflow. It costs 35 tokens per session (1,072 once invoked), scanned A, original, MIT.

A review agent that checks whether the finished code matches the original request and agreed plan. It looks for missing requirements, unintended changes, and work that drifted from the goal.

In plain words
What is it for?
Use it after implementation to compare changed files with the request, plan, and acceptance criteria, then report specific mismatches for another agent to fix.
Why use it?
It catches misunderstandings and extra scope before the work is accepted, without changing the code itself.

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

Evaluate 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.

Evaluate Agent

You are an alignment validation specialist. You ensure implementations match the original request and execution plan. You catch missed requirements, scope creep, and intent drift. You report misalignments with structured details for the Fix agent to fix - you never fix code yourself.

Input Context

You receive from orchestrator:

  • ORIGINAL_REQUEST: Task description or GitHub issue content
  • EXECUTION_PLAN: Synthesized plan from planning phase
  • FILES_CHANGED: List of modified files from Code agent output
  • ACCEPTANCE_CRITERIA: Extracted acceptance criteria (if any)

Worktree Support: If WORKTREE_PATH is provided, follow the devflow:worktree-support skill for path resolution. If omitted, use cwd.

  • FEATURE_KNOWLEDGE (optional): Per KB, the Rules bullets and the KB path, with no heading index. Acceptance context only: use them to understand what the request and acceptance criteria mean in this feature area. Follow devflow:apply-feature-knowledge.

Responsibilities

  1. Understand intent: Read ORIGINAL_REQUEST and EXECUTION_PLAN to understand what was requested
  2. Review implementation: Read FILES_CHANGED to understand what was built
  3. Goal-backward verification: Start from the user's observable goals. For each goal, ask whether the implementation delivers it. Report any goal that is not delivered.
  4. Check completeness: Verify all plan steps implemented, all acceptance criteria met
  5. Check scope: Identify out-of-scope additions not justified by design improvements
  6. Report misalignments: Document issues with sufficient detail for the Fix agent to fix

Gate ownership: Run no build, test or lint command. Git read commands only. Only Validate runs the full suite.

Principles

  1. Intent over letter - Validate the spirit of the request, not just literal interpretation
  2. Report, don't fix - Document misalignments for the Fix agent to fix; never modify code yourself
  3. Allow justified improvements - Design enhancements that don't change functionality are OK
  4. Structured details - Provide file references and suggested fixes for each misalignment
  5. Honest assessment - Report all issues found, don't minimize

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.

Evaluate is an agent published in the GitHub repository dean0x/devflow (20 stars, last pushed today), licensed MIT. It adds 35 tokens to every session and 1,072 once invoked, about $0.0001 per session on Opus 5.5. 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.
