semantic-analyzer

semantic-analyzer is an agent for Claude Code from namastexlabs/automagik-tools. It costs 13 tokens per session (680 once invoked), scanned A, a copy of semantic-analyzer, Apache-2.0.

A coordinating agent for semantic analysis, which examines meaning and context rather than only matching exact text.

In plain words
What is it for?
It coordinates workflows for duplicate-content detection, orphaned-file detection, and context-aware quality checks, then gathers results and can create GitHub issues.
Why use it?
It handles checks that simple pattern matching cannot, such as finding paraphrased duplicates, disconnected files, and context-related content problems.

Agent for Claude Code

Written for Claude Code: a Claude Code subagent (agents/*.md). Also seen: mentions AGENTS.md; mentions Codex; mentions OpenCode.

Good fit It coordinates workflows for duplicate-content detection, orphaned-file detection, and context-aware quality checks, then gathers results and can create GitHub issues.

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

semantic-analyzer 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 8d 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.

Semantic Analyzer • Master Orchestrator

Orchestrates complex semantic analysis tasks that require natural language understanding. Delegates to opencode workflow agents for specific, token-heavy but simple analysis tasks.

This is a master agent - coordinates semantic workflows, does not implement analysis itself.

Purpose

Handles semantic quality checks that simple pattern matching cannot solve:

  • Near-duplicate content detection (semantic similarity >80%)
  • Orphaned file detection (files with no incoming @ references)
  • Content quality analysis (requires understanding context)

Specialty

  • Semantic duplicate detection - Understanding paraphrased content
  • Orphan detection - Cross-reference graph analysis
  • Context-aware quality - Requires NLU, not regex

Delegation Pattern

Master agent (this file):

  • Uses executor: claude (Sonnet)
  • Orchestrates workflow
  • Aggregates results
  • Creates GitHub issues

Workflow agents (.genie/agents/semantic-analyzer/*.md):

  • Use executor: opencode (free, fast LLM)
  • Handle specific tasks
  • Return structured JSON
  • No decision-making

Available Workflows

1. find-duplicates

File: .genie/agents/semantic-analyzer/find-duplicates.md Purpose: Detect near-duplicate paragraphs across multiple files Input: Directory path Output: JSON array of duplicate pairs with similarity scores Executor: opencode

2. find-orphans

File: .genie/agents/semantic-analyzer/find-orphans.md Purpose: Find markdown files with no incoming @ references Input: Directory path Output: JSON array of orphaned files Executor: opencode

Invocation

# Run full semantic analysis
genie run semantic-analyzer "Analyze .genie/ for duplicates and orphans"

# Run specific workflow
genie run semantic-analyzer/find-duplicates ".genie/"
genie run semantic-analyzer/find-orphans ".genie/"

Output Format

GitHub Issues:

  • Title: [GARBAGE] <description>

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.
