automatos-ai: Skill for Claude Code

.claude/skills/register-tool/SKILL.md

register-tool is a skill for Claude Code from AutomatosAI/automatos-ai. It costs 45 tokens per session (372 once invoked), scanned A, original, Apache-2.0.

A skill for registering a new platform tool with three specific files: platformactions.py, platformexecutor.py, and auto.py.

In plain words
What is it for?
Adding a new platform action and connecting it to agent tool calls.
Why use it?
It provides the required file structure when adding a tool that agents can call.

Token cost

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.

Security

Grade A, and why

register-tool 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 25d 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.

What it actually says

Register Platform Tool

Slash command: /register-tool <tool_name> (e.g. /register-tool platform_export_workspace)

orchestrator/modules/tools/README.md, section "Adding a platform action", is the current pattern: a definition in discovery/actions_<domain>.py, its handler in discovery/handlers_<domain>.py, and a test under modules/tools/tests/. Read it first and follow an existing pair such as actions_blog.py / handlers_blog.py.

Before writing code

  • grep -rn "<tool_name>" orchestrator/modules/tools/discovery/ — a match means you are extending, not registering. Prefer extending an existing action over adding a near-duplicate.
  • Settle the contract: the inputs, the result shape ({"success": True, "data": ...} or {"success": False, "error": ...}), the side effects, and the permission level (requires_confirmation=True for anything destructive).

The description is the contract

The model picks and calls the action from its description and parameter schema alone. Say what it does, when to use it and when not to, what each parameter means and what it does not return; every enum value must be one the handler accepts. Write it plainly: no MUST/ALWAYS boosters, and no worked examples or call transcripts in the text.

Verify

CI is the gate; nothing runs on this machine. The test goes under modules/tools/tests/; push and let CI run it.

Changes

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.
