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 5.1 | $0.00113 | $0.01749 |
| Opus 5 | $0.00056 | $0.00874 |
| Sonnet 5 | $0.00023 | $0.00350 |
| Haiku 4.5 | $0.00011 | $0.00175 |
Grade A, and why
claude-to-omniharness scanned grade A with 1 finding 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 11d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

OmniHarness Skill
Communicate with a running OmniHarness instance via its HTTP API. OmniHarness is an AI agent platform built on LangGraph that orchestrates sub-agents for research, code execution, web browsing, and more.
Architecture
OmniHarness exposes two API surfaces behind an Nginx reverse proxy:
| Service | Direct Port | Via Proxy | Purpose |
|---|---|---|---|
| Gateway API | 8001 | $DEERFLOW_GATEWAY_URL |
REST endpoints (models, skills, memory, uploads) |
| LangGraph API | 2024 | $DEERFLOW_LANGGRAPH_URL |
Agent threads, runs, streaming |
Environment Variables
All URLs are configurable via environment variables. Read these env vars before making any request.
| Variable | Default | Description |
|---|---|---|
DEERFLOW_URL |
http://localhost:2026 |
Unified proxy base URL |
DEERFLOW_GATEWAY_URL |
${DEERFLOW_URL} |
Gateway API base (models, skills, memory, uploads) |
DEERFLOW_LANGGRAPH_URL |
${DEERFLOW_URL}/api/langgraph |
LangGraph API base (threads, runs) |
When making curl calls, always resolve the URL like this:
# Resolve base URLs from env (do this FIRST before any API call)
DEERFLOW_URL="${DEERFLOW_URL:-http://localhost:2026}"
DEERFLOW_GATEWAY_URL="${DEERFLOW_GATEWAY_URL:-$DEERFLOW_URL}"
DEERFLOW_LANGGRAPH_URL="${DEERFLOW_LANGGRAPH_URL:-$DEERFLOW_URL/api/langgraph}"
Available Operations
1. Health Check
Verify OmniHarness is running:
curl -s "$DEERFLOW_GATEWAY_URL/health"
2. Send a Message (Streaming)
This is the primary operation. It creates a thread and streams the agent's response.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

claude-to-omniharness is a skill published in the GitHub repository archimedes-run/omniHarness (7 stars, last pushed 16d ago), licensed MIT. It adds 113 tokens to every session and 1,749 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
