SessionStart

SessionStart is a hook for coding agents from dantte-lp/oarx-docs-mcp. Its token cost is not measured, scanned A, original, MIT.

A session-start hook that prints a message when a coding session begins, telling you that ObjectARX 2026 documentation is available. ObjectARX is Autodesk's C++ programming interface for extending AutoCAD.

In plain words
What is it for?
It helps prepare sessions involving AutoCAD extensions by pointing to documentation search, class lookup, and guide-listing tools.
Why use it?
It reminds you at the start of a session where the relevant documentation is available, so you do not have to remember or search for it manually.

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.

Clone the repo
git clone --depth 1 https://github.com/dantte-lp/oarx-docs-mcp

Or install oarx-docs, the plugin that ships this one along with the rest of its 4 skills, 2 commands, 1 hook.

Security

Grade A, and why

SessionStart 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 3d ago.

A static scan of the commands this hook runs, not an audit. A hook is shell that executes on your machine at the event it names, which is why every command in it is printed with what was found.

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.

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.
