## Tools (as reported by the server, not verified)

- `size\_expansion\_vessel`: DETERMINISTIC: the same inputs always give the same result — from any AI, on any day. Figures come from the standard's tables and formulas, never from a language model's estimate. Every step is auditable. Size the expansion vessel and pressurisation of a closed heating or chilled-water circuit to EN
- `water\_content\_from\_vessel`: DETERMINISTIC: the same inputs always give the same result — from any AI, on any day. Figures come from the standard's tables and formulas, never from a language model's estimate. Every step is auditable. Deduce the water content of an installation from the expansion vessel already fitted. WHAT THIS
- `check\_refrigerant\_switzerland`: DETERMINISTIC: the same inputs always give the same result — from any AI, on any day. Figures come from the regulation's annexes and thresholds, never from a language model's estimate. Every step is auditable. Swiss refrigerant regulation check \(ORRChim / ChemRRV annex 2.10, OFEV synthesis of May 20
- `check\_en378\_zones`: DETERMINISTIC: the same inputs always give the same result — from any AI, on any day. Figures come from the standard's tables and formulas, never from a language model's estimate. Every step is auditable. EN 378 applied to BUILDING projects, volume by volume. An installation does not occupy one room
- `read\_ifc\_overview`: CALL THIS FIRST, as soon as the user gives you a token - a link thenewengineer.com/ia/XXXX pasted in the conversation - BEFORE you answer anything, even when the user only says they will choose or do something themselves. It answers within seconds, while the network graph is still being built - use
- `apply\_ifc\_rules`: Turn what you read in the overview into rules the tool replays on EVERY piece of the model, including the ones you were never shown. NOT NEEDED ON A MODEL ALREADY TREATED: when read\_ifc\_overview returns 'designation\_existante', the units and fans are already designated - reuse them. Posting rules RE
- `read\_ifc\_networks`: DETERMINISTIC: networks come from geometry, not from a guess. The same model always gives the same networks, from any AI, on any day. Read the networks of an IFC model already uploaded by the user. WHAT A NETWORK IS. A set of parts that touch each other, cut at equipment: a pump, an air handling uni
- `name\_ifc\_networks`: Apply the names you propose, and get back the updated report. THE NAMES ARE YOURS, THE NETWORKS ARE NOT. You are naming what the tool measured; you are not changing what it measured. Nothing you send here alters a network, a part, or a correction. WHAT COMES BACK. The updated report, a 3D link where
- `trace\_duct\_circuits`: THE CIRCUITS THE FANS OF A MODEL ARE SIZED ON, found without anyone clicking and computed on the pressure-drop page, where the user confirms types and flows and reads the pressure drops. THE USER WANTS TO PICK THE UNITS THEMSELVES: call this tool with ONLY the token right away, and give them 'lien\_c
- `open\_ifc\_upload`: Show an upload box in the conversation where the user can drop an IFC file \(.ifc\) of a building services model \(HVAC, plumbing, heating\). The file goes straight from the user's browser to thenewengineer.com - you never see it. CALL THIS when the user wants to analyse an IFC model and has not yet giv
- `ifc\_upload\_result`: Where the upload stands. When \`state\` is \`depose\`, \`token\` is the token to pass to read\_ifc\_networks.
