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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00013 | $0.00673 |
| Opus 5 | $0.00006 | $0.00336 |
| Sonnet 5 | $0.00003 | $0.00135 |
| Haiku 4.5 | $0.00001 | $0.00067 |
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 2d 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/"

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.
- 2d ago First seen · 101 lines · 13 tokens per session scan A 29a3f68b58b1
semantic-analyzer is an agent published in the GitHub repository automagik-dev/forge (89 stars, last pushed 8mo ago), licensed Apache-2.0. It adds 13 tokens to every session and 673 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
