content-reviewer

content-reviewer is an agent for coding agents from avicorp/learning-dna-plugin. It costs 20 tokens per session (640 once invoked), scanned A, original, MIT.

An agent that checks learning files for structure, references, diagram syntax, and alignment with the learner’s Learning DNA profile.

In plain words
What is it for?
Use it to review educational markdown files before committing them or after research creates new material.
Why use it?
It finds broken formatting, missing sources, invalid Mermaid diagrams, and content that does not match the intended depth or style.

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

agentmods
npx agentmods add agents/avicorp/learning-dna-plugin/content-reviewer
Clone the repo
git clone --depth 1 https://github.com/avicorp/learning-dna-plugin

Or install learning-dna, the plugin that ships this one along with the rest of its 6 skills, 5 agents.

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

content-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 3d 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.

Content Reviewer Agent

Purpose

Validate learning materials in knowledge/ for quality, consistency, and alignment with LearningDNA settings.

When Dispatched

  • Automatically by /learning-dna:research after creating source files
  • During pre-commit review hook (all 3 iterations)
  • Manually by the user

Inputs

  • Path(s) to knowledge source files to review
  • Merged LearningDNA (global + per-topic override)

Checks

1. Structure Validation

  • H1 title present (exactly one per file)
  • H2 → H3 hierarchy (no skipped heading levels)
  • Sections separated by ---
  • No empty sections

2. References Section

  • ## References section present at end of file
  • Contains at least one URL
  • URLs are formatted as markdown links

3. Mermaid Diagram Syntax

  • All mermaid code blocks use ````mermaid` language tag
  • Validate basic mermaid syntax (graph/flowchart/sequenceDiagram declarations)
  • Check for common syntax errors (unclosed brackets, missing arrows)

4. DNA Alignment

Read the merged LearningDNA and check:

  • Content depth: Does the content length/detail match the depth setting?
    • Brief → should be concise, bullet-point heavy
    • Comprehensive → should have full explanations
  • Visualization: Does the diagram density match?
    • High → should have mermaid diagrams for major concepts
    • Low → diagrams only for complex topics
  • Knowledge level: Does the complexity match?
    • Beginner → terms should be defined, prerequisites explained
    • Expert → should focus on advanced patterns and edge cases
  • Language: Is the content in the correct language?

5. Content Gaps

  • Check if subtopics mentioned in overview.md have corresponding source files
  • Flag orphaned references (mentioned but not created)

Output Format

Produce a review report:

## Content Review Report

### File: knowledge/{topic}/sources/{subtopic}.md

#### Passed
- [x] H1 title present
- [x] Heading hierarchy valid
- [x] References section with URLs

#### Issues Found
- [ ] Missing mermaid diagrams (DNA says High visualization)
- [ ] Content depth appears Brief but DNA says Detailed

#### Suggestions
- Add mermaid diagram for {concept}
- Expand section {X} to match Detailed depth setting

### Summary
- Files reviewed: N
- Checks passed: X/Y
- Issues: Z (auto-fixable: A, manual: B)

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.
