agent-self-evaluation

agent-self-evaluation is a skill for Claude Code, Codex from ufy2024/AuC. It costs 60 tokens per session (1,864 once invoked), scanned A, original, MIT.

A review step that rates completed non-trivial work for accuracy, completeness, clarity, usefulness, and conciseness.

In plain words
What is it for?
Use it after larger coding tasks, multi-step workflows, debugging sessions, design documents, or when asking for a self-assessment.
Why use it?
It can reveal unsupported claims, missing requirements, confusing explanations, or unnecessary detail before the work is handed over.

About the project

AuC is a Python framework for running a single AI agent with an asynchronous, pluggable reasoning loop, language-model adapters, permission levels, and observable events. It is used to build coding and conversational agents with tools, security checks, web interfaces, background jobs, evaluations, and isolated execution. The catalogue entries are skills for extending its agent workflow.

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

agent-self-evaluation 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 5d 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.

How it starts

The opening of the file, as written. The whole thing — 205 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Agent Self-Evaluation

After completing a complex task, the agent pauses to rate its own output against a structured 5-axis rubric. This is NOT a pass/fail gate — it's a deliberate reflection step that catches omissions, flags overconfidence, and surface areas for improvement before the user has to.

When to Activate

  • After writing code that spans 3+ files or 50+ lines
  • After completing a multi-step workflow (implement → test → review)
  • After a debugging session that involved 3+ attempts
  • After producing a design document, architecture decision, or written analysis
  • When the user asks "how good was that?" or "rate yourself"
  • At the end of any session Stop hook (if configured — see references/hook-integration.md)

Core Concepts

The 5 Evaluation Axes

Axis Question What it catches
Accuracy Are the facts, claims, and outputs correct? Hallucinations, wrong API names, incorrect syntax, false statements
Completeness Did it cover everything the user asked for? Missed edge cases, unhandled error paths, forgotten requirements, skipped subtasks
Clarity Is the explanation understandable and well-structured? Confusing explanations, jargon without definition, missing context, rambling
Actionability Can the user act on the output immediately? Vague suggestions, missing steps, "you should X" without showing how, no verification path
Conciseness Did it use the minimum words/tokens needed? Redundancy, over-explanation, repeating the user's question verbatim, filler content

Scoring Scale

5 — Exceptional: no reasonable improvement possible
4 — Good: minor nits only, no substantive gaps
3 — Adequate: meets the request but has a notable weakness on at least one axis
2 — Weak: has a clear gap that affects usability or correctness
1 — Poor: fundamentally misses the request or contains significant errors

The Evidence Rule

Every score below 5 MUST cite specific evidence. A score of 3 cannot just say "could be better" — it must say exactly what is missing or wrong. The mantra: "Show the gap, don't just name it."

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.
