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 | $0.00065 | $0.01655 |
| Opus 5.5 | $0.00026 | $0.00662 |
| Sonnet 5.5 | $0.00013 | $0.00331 |
| Haiku 4.5 | $0.00006 | $0.00166 |
Grade A, and why
systems-manager-development 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 yesterday.
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 — 147 lines — stays where its author put it; the contents beside it link to each section on GitHub.
systems-manager development
systems-manager is a Python connector that exposes governed host inspection and
host-lifecycle operations through the Agent Connector SDK. Keep the provider's
runtime boundary narrow: package operations, service/process/network/disk
inspection, storage health, managed-file policy, and typed host telemetry belong
here; durable graph storage, Arbora admission, and deployment credentials belong
to their owning systems.
Repository map and real entry points

In particular,tests/test_default_content_surfaces.pyverifies that packaged skills, ontology, and prompts remain discoverable through the server.
There is no systems_manager/agent_server.py in the current source tree. Do not
document or invoke that stale path; the MCP server entry point is
systems_manager.mcp_server:mcp_server.
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.

systems-manager-development is a skill published in the GitHub repository Knuckles-Team/systems-manager (3 stars, last pushed yesterday), licensed MIT. It adds 65 tokens to every session and 1,655 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-10-27.
