# Evaluation Skill

Guidelines for creating comprehensive evaluation suites.

## When to Use This Skill

Use this skill when:
- Creating a NEW evaluation suite for a feature
- Updating an EXISTING evaluation suite
- Understanding the evaluation framework patterns
- Writing spec.yaml, rubric.md, or evaluation files

## Evaluation Framework Overview

All evaluations in `evals/` follow a consistent structure with both **code-based** and **LLM-as-judge** validations.

## spec.yaml Template

Use this template for all eval spec.yaml files:

```yaml
feature:
  name: "[Feature Name] Evaluation"
  as_a: evaluator
  i_want: validate feature behavior
  solutions:
    - Ground truth validation
    - Code-based validation
    - LLM-as-judge validation

requirements:
  - id: REQ-EVAL-XX-001
    eval: G
    description: Description of ground truth requirement
  - id: REQ-EVAL-XX-002
    eval: C
    description: Description of code-based requirement
  - id: REQ-EVAL-XX-003
    eval: L
    description: Description of LLM-judged requirement
  - id: REQ-EVAL-XX-004
    eval: O
    description: Description of planned requirement
```

**Template Rules:**
- **Identifier Format**: `REQ-EVAL-XX-NNN`
  - `XX` = 2-3 letter eval abbreviation (e.g., AG for action_generation, AS for action_scenarios)
  - `NNN` = Sequential 3-digit number starting at 001
- **Implementation Types**:
  - `[G]` = Ground truth validation (matches expected output)
  - `[C]` = Code-based validation (deterministic checks)
  - `[L]` = LLM-as-judge validation (quality assessment)
  - `[O]` = Not yet implemented (planned for future)
- **Categories**: Group related requirements logically

## rubric.md Template

Use this template for all rubric.md files:

```markdown
# [Feature Name] Reasoning Trace Rubric

## Format
`[PASS/FAIL] RUBRIC-ID: Criterion description`

## Based on: [Concrete example with specific values]

### [Category Name]
- [ ] RUB-XX-001: Specific, objective criterion
- [ ] RUB-XX-002: Another specific criterion
```

**Template Rules:**
- **Identifier Format**: `RUB-XX-NNN` (matches spec.yaml abbreviation)
- **Categories**: Organize criteria into logical groups
- **Criteria**: Write concrete, objectively verifiable rules, not subjective assessments
- **Specificity**: Reference actual values, fields, or behaviors that can be checked
- **Checkboxes**: Use `- [ ]` format for LLM judge to mark pass/fail
- **Avoid subjective language**: Do not use vague terms; state exactly what to verify

skill-development

Included

Comprehensive meta-skill for creating, managing, validating, auditing, and distributing Claude Code skills and slash commands (unified in v2.1.3+). Provides skill templates, creation workflows, validation patterns, audit checklists, naming conventions, YAML frontmatter guidance, progressive disclosure examples, and best practices lookup. Use when creating new skills, validating existing skills, auditing skill quality, understanding skill architecture, needing skill templates, learning about YAML frontmatter requirements, progressive disclosure patterns, tool restrictions (allowed-tools), skill composition, skill naming conventions, troubleshooting skill activation issues, creating custom slash commands, configuring command frontmatter, using command arguments ($ARGUMENTS, $1, $2), bash execution in commands, file references in commands, command namespacing, plugin commands, MCP slash commands, Skill tool configuration, or deciding between skills vs slash commands. Delegates to docs-management skill for official documentation.

reprompter

Included

Transform messy prompts into well-structured, effective prompts — single or multi-agent. Use when: "reprompt", "reprompt this", "clean up this prompt", "structure my prompt", rough text needing XML tags and best practices, "reprompter teams", "repromptception", "run with quality", "smart run", "smart agents", multi-agent tasks, audits, parallel work, anything going to agent teams. Don't use when: simple Q&A, pure chat, immediate execution-only tasks. See "Don't Use When" section for details. Outputs: Structured XML/Markdown prompt, quality score (before/after), optional team brief + per-agent sub-prompts, agent team output files. Success criteria: Single mode quality score ≥ 7/10; Repromptception per-agent prompt quality score 8+/10; all required sections present, actionable and specific.

adaptive-compaction

Included

Adaptive add-on policy and recovery layer that decides WHEN to compact, prune, snapshot, or fork -- replacing fixed-percent auto-compaction across Claude Code, Codex, and MCP-capable hosts. Trigger on auto-compact timing or damage: "when should I compact", "is it safe to compact now or start a fresh session", "auto-compact fires too early/mid-task", "switching to an unrelated task but the window still has space", "context rot", "answers get worse the longer the session runs", "the agent forgot the plan or my decisions after it summarized", "add a layer on top that manages context without changing the agent", raising autoCompactWindow to give the policy room, or installing/tuning a cross-tool compaction policy or PreCompact hook -- even when "compaction" is never said but the problem is context-window pressure or post-summarization memory loss. Do NOT use to summarize a conversation, build RAG, write a summarization prompt (decides WHEN not HOW), or answer max-context-length trivia.

AI Agentsscripts

agent-skill-creator

Included

Create cross-platform agent skills from workflow descriptions. Activates when users ask to create an agent, automate a repetitive workflow, create a custom skill, or need advanced agent creation. Triggers on phrases like create agent for, automate workflow, create skill for, every day I have to, daily I need to, turn process into agent, need to automate, create a cross-platform skill, validate this skill, export this skill, migrate this skill. Supports single skills, multi-agent suites, transcript processing, template-based creation, interactive configuration, cross-platform export, and spec validation.

llm-wiki

Included

Use when building or maintaining a persistent personal knowledge base (second brain) in Obsidian where an LLM incrementally ingests sources, updates entity/concept pages, maintains cross-references, and keeps a synthesis current. Triggers include "second brain", "Obsidian wiki", "personal knowledge management", "ingest this paper/article/book", "build a research wiki", "compound knowledge", "Memex", or whenever the user wants knowledge to accumulate across sessions instead of being re-derived by RAG on every query.

AI Agentsscripts

skill-master

Included

Agent Skills authoring, evaluation, and optimization. Create, edit, validate, benchmark, and improve skills following the agentskills.io specification. Use when designing SKILL.md files, structuring skill folders (references, scripts, assets), ingesting external documentation into skills, running trigger evals, benchmarking skill quality, optimizing descriptions, or performing blind A/B comparisons. Keywords: agentskills.io, SKILL.md, skill authoring, eval, benchmark, trigger optimization.
