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.

SkillSpector: 1 finding, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high Tool Misuse · line 162 Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).Fix: Validate all tool parameters against an allowlist. Reject dangerous parameter values (shell=True, --force, -rf /) and use safe defaults.
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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00030 | $0.01978 |
| Opus 5 | $0.00015 | $0.00989 |
| Sonnet 5 | $0.00006 | $0.00396 |
| Haiku 4.5 | $0.00003 | $0.00198 |
Grade A, and why
nexus 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.

Kailash Nexus - Multi-Channel Platform Framework
Nexus is a zero-config multi-channel platform built on Kailash Core SDK that deploys workflows as API + CLI + MCP simultaneously.
Features
Nexus transforms workflows into a complete platform with:
- Zero Configuration: Deploy workflows instantly without boilerplate code
- Multi-Channel Access: API, CLI, and MCP from single deployment
- Unified Sessions: Consistent session management across all channels
- Enterprise Features: Health monitoring, plugins, event system, comprehensive logging
- DataFlow Integration: Automatic CRUD API generation from database models
- Production Ready: Deployment patterns, monitoring, troubleshooting guides
- Zero-Config Platform: Workflow-based platform without manual route definition
- Async-First: Uses AsyncLocalRuntime by default for optimal performance
Quick Start
from nexus import Nexus
# Define workflow
workflow = create_my_workflow()
# Deploy to all channels at once
app = Nexus()
app.register("my_workflow", workflow.build())
app.start()
# Now available via:
# - HTTP API: POST http://localhost:8000/api/workflow/{workflow_id}
# - CLI: nexus run {workflow_id} --input '{"key": "value"}'
# - MCP: Connect via MCP client (Claude Desktop, etc.)

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.

nexus is a skill published in the GitHub repository terrene-foundation/kailash-coc-claude-py (12 stars, last pushed 24d ago), licensed Apache-2.0. It adds 30 tokens to every session and 1,978 once invoked, about $0.0002 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 2026-09-03.
