Validates all interactive skills in this repo against the Agent Skills spec, project conventions, and structural requirements. Runs quick_validate.py, checks line limits, verifies cross-references, and tests hook scripts. Use when skills have been added or modified and you want to verify everything passes before committing or submitting.

What this skill does


# Skill Tester

Validates all interactive (non-CI) skills in this repo. Runs the Anthropic skill-creator's `quick_validate.py` plus project-specific checks.

## When to Use

- After adding or modifying a skill
- Before committing changes
- Before submitting the plugin for Anthropic review
- As part of the outer loop when eval-creator needs to verify skill quality

## Checks

### 1. Anthropic Spec Validation

Run `quick_validate.py` on every skill in `skills/` (excluding `-ci` variants):

```bash
for d in skills/*/; do
  skill=$(basename "$d")
  [[ "$skill" == *-ci ]] && continue
  python3 .claude/skills/skill-creator/scripts/quick_validate.py "$d"
done
```

**Pass criteria:** Exit code 0 for every skill. Frontmatter has only allowed keys (`name`, `description`, `license`, `allowed-tools`, `metadata`, `compatibility`). Name is kebab-case, max 64 chars. Description max 1024 chars, no angle brackets.

### 2. Project Convention Checks

For each skill directory:

| Check | Rule | Severity |
|-------|------|----------|
| Name matches folder | Frontmatter `name` == directory name | Error |
| Line limit | SKILL.md at or under 600 lines | Error |
| No README.md | Skill folders must not contain README.md | Error |
| Scripts executable | All `.sh` files in `scripts/` must have execute permission | Error |
| References exist | Files referenced in SKILL.md body actually exist in `references/` | Warning |
| Description non-empty | Description field is present and non-empty | Error |

### 3. Cross-Reference Validation

Verify that all skills listed in these files actually exist as directories:

- `CLAUDE.md` — Skill References section
- `AGENTS.md` — Skill References section
- `.github/copilot-instructions.md` — Skill References section
- `README.md` — Skills table

Also verify reverse: every skill directory is listed in all four files.

### 4. Hook Script Testing

For each skill with a `scripts/` directory:

```bash
# Syntax check
bash -n scripts/*.sh

# Verify shebang
head -1 scripts/*.sh | grep -q "^#!/bin/bash"

# Verify executable
test -x scripts/*.sh
```

### 5. Plugin Skill Validation

For skills that exist in both `skills/` and `plugin/skills/`:

| Check | Rule |
|-------|------|
| Plugin frontmatter keys | Only Claude Code-specific keys (`hooks`, `user-invocable`, `argument-hint`) added beyond spec |
| Content alignment | Body content matches or plugin has extracted references |
| Beta markers consistent | If `skills/` copy has `[Beta]`, plugin copy should too |

## Output Format

```markdown
## Skill Test Results

**Date:** YYYY-MM-DD
**Skills tested:** N
**Passed:** N
**Warnings:** N
**Failed:** N

### Failures
- [skill-name]: [check]: [error message]

### Warnings
- [skill-name]: [check]: [warning message]

### All Passed
- [list of clean skills]
```

## Running

Invoke manually:
```
/skill-tester
```

Or run the script directly:
```bash
bash skills/skill-tester/scripts/run-tests.sh
```

## What This Skill Does NOT Do

- Does not test CI skills (use `skill-tester-ci` for those)
- Does not modify skills — reports findings only
- Does not run behavioral evals (trigger testing) — use skill-creator's `run_eval.py` for that
- Does not replace the eval-creator regression framework — this tests skill structure, not promoted rules

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.

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.
