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 | $0.00024 | $0.01150 |
| Opus 5 | $0.00012 | $0.00575 |
| Sonnet 5 | $0.00005 | $0.00230 |
| Haiku 4.5 | $0.00002 | $0.00115 |
Grade A, and why
heyreach-master 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 10d 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.
How it starts
The opening of the file, as written. The whole thing — 181 lines — stays where its author put it; the contents beside it link to each section on GitHub.
HeyReach Master (Internal)
Internal resource library containing:
- API client (
heyreach_client.py) - Config checker (
check_heyreach_config.py) - All operation scripts
- Reference documentation
Architecture: DRY Principle
Problem solved: HeyReach skills would have duplicated content (setup instructions, API docs, auth flow, error handling).
Solution: Extract shared content into heyreach-master/references/ and heyreach-master/scripts/, then reference from each skill.
Result: Single source of truth, reduced context per skill.
Shared Resources
All HeyReach skills reference these resources (progressive disclosure).

Authentication & Configuration
check_heyreach_config.py - Pre-flight validation
uv run python check_heyreach_config.py [--json]
| Argument | Required | Default | Description |
|---|---|---|---|
--json |
No | False | Output structured JSON for AI consumption |
Exit codes: 0=configured, 1=partial, 2=not configured
When to Use: Run this FIRST before any HeyReach operation. Use to validate API key is configured, diagnose authentication issues, or check if setup is needed.
heyreach_client.py - Shared API client
from heyreach_client import get_client, HeyReachError
client = get_client()
result = client.post("/v2/campaigns/All", {"offset": 0, "limit": 100})
Features:
- Automatic retry with exponential backoff
- Rate limit handling (300 req/min)
- Consistent error responses
- API key management from .env

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.

heyreach-master is a skill published in the GitHub repository DorianSchlede/nexus-template (8 stars, last pushed 7mo ago), licensed MIT. It adds 24 tokens to every session and 1,150 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 2026-08-31.
