ipsymcon

ipsymcon is a skill for Claude Code, Codex from Schimmilab/ipsymcon-mcp-server. It costs 49 tokens per session (1,679 once invoked), scanned A, original, MIT.

A set of instructions for inspecting and changing an IP-Symcon home-automation system. IP-Symcon manages devices such as heating, blinds, sockets, sensors, scripts, and events.

In plain words
What is it for?
Use it to inspect the object tree, create or edit PHP scripts, configure variables and events, and change automations in IP-Symcon.
Why use it?
It adds a safety process before changes are made to a live home. The agent reads the current setup, presents a plan, gets approval, then applies and reports the changes.

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

ipsymcon 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 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.

IP-Symcon development

This skill turns you into a careful developer inside a live IP-Symcon home automation. You don't just switch devices — you read the system, build PHP scripts, create variables and events, and grow the automation. The ipsymcon MCP is your hands; this skill is the playbook for using them well and safely.

  • How to carry out a change (step-by-step workflows, plan & report templates, pitfalls): references/workflow.md.
  • ips_call function cheat-sheet (signatures + recipes for event triggers, profiles, instances, rename/move/delete): references/ips-functions.md.

The one rule that matters: plan before you touch

IP-Symcon runs a real house — heating, blinds, sockets, sensors. A wrong write can have physical consequences. So the workflow is read → plan → approve → execute → report, never "change first, explain later". The user explicitly wants to see what will change, from where to where, before anything happens. There is also an IP-Symcon backup as a safety net, but the plan is the primary guardrail.

  1. Start in plan mode (EnterPlanMode). Reading is fine — explore freely.
  2. Resolve and read the current state of everything you intend to change. IDs are opaque integers; never guess them, always resolve from names/tree.
  3. Assemble a plan naming every change as a concrete operation with a clear before → after (template in workflow.md).
  4. Present the plan via ExitPlanMode and stop. Do not call a single write tool yet.
  5. Only after approval, execute the writes in order, capturing each result.
  6. Report exactly what changed — every operation performed, with IDs and before/after. If a step fails, stop and report; don't push on.

If you ever find yourself about to call any write/dev tool (anything in the second table below) before the user has seen and approved a plan — stop. That's the failure mode this skill exists to prevent.

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.
