Use the moment a request is underspecified and you are about to act on an ASSUMED goal. Enumerate the candidate goals the request could mean, project the action or artifact each one implies, and check whether they diverge: if two or more plausible goals lead to materially different actions or artifacts, ask exactly ONE targeted clarifying question; otherwise proceed on the most-likely goal and state the assumption in one line. Clarification is an evidence-producing action, not a delay — but one question, never an interrogation. Distinct from gsd-spec-phase (GSD-phase-bound, emits a heavy SPEC.md) and intent-router (fetch strategy, not goal disambiguation). Backed by agent goal-state inference (arxiv 2606.16813v1). Triggers on acting under an assumed goal when the request admits more than one materially different reading.
Use at write time to vector/embedding memory — Grove content-addressed insertion, chroma/pgvector upserts, memory-consolidation promoting session traces to MEMORY.md, or embedding externally-ingested content. Scores each candidate record against a fixed panel of sentinel queries and quarantines any record that would become the nearest neighbor of too many unrelated queries — a hub — whether from adversarial poisoning or accidental over-generality. This is the memory-record-side sibling of skill-injection-guardian (file-side) and the write-side complement of memory-use-warrant (read-side). Quarantine, never silently drop; a human reviews. Backed by the admission-time hubness gate (arxiv 2606.19692v1). Triggers on inserting into vector memory, consolidating memory, and embedding stranger content.
Run this appropriateness check the moment you are about to integrate a retrieved long-term memory — a Grove content-addressed hit, a chroma/pgvector neighbour, a memory-consolidation digest, or a MEMORY.md line — into a response, especially anything touching private origins, Fox Companies IP, credentials, or Center Camp / consent-governed content. It answers a question intent-router never asks: not WHAT to fetch or HOW, but WHETHER a correctly-retrieved item should reach output. Relevance is not appropriateness — a perfect similarity match can still be a boundary violation. Default is FAIL-CLOSED: if in-context authorization is uncertain, the memory may inform behaviour but must not be surfaced. Backed by RBI-Eval (arxiv 2606.06055v1). Triggers on surfacing recalled sensitive memory into a response.

Convert verified engineering calculations into standard engineering drawings: P&ID, SLD, floor plans, and isometric piping views with SVG/DXF output.
Activation: BlueprintPackage generation request, any drawing type request (P&ID, SLD, floor plan, isometric), SVG/DXF output formatting, or title block creation.
Key capabilities:
Drawing types:
| Drawing Type | Standard | Primary Use |
|---|---|---|
| P&ID | ISA-5.1 | Piping and instrumentation, fluid systems |
| SLD | IEEE | Single-line electrical diagrams, power distribution |
| Floor Plan | Site-specific | Equipment layout, spatial relationships |
| Isometric | ASME | 3D pipe routing in 2D representation |
Output formats: SVG (primary, web-renderable) and DXF (CAD import via svg2dxf).
When to use this skill:
Mandatory in every drawing:
ENGINEERING DISCLAIMER
This output was generated by an AI assistant and has NOT been reviewed
by a licensed Professional Engineer (PE). All calculations, drawings,
and specifications must be verified by a qualified professional before
use in any construction, installation, or operational context. Local
building codes, electrical codes, and plumbing codes may impose
requirements not captured in this output. The user assumes all
responsibility for verification and compliance.
ENGINEERING DISCLAIMER: All drawings generated by this skill must be verified by a licensed Professional Engineer (PE) before use in construction, installation, or operational contexts. This disclaimer is non-removable and applies to all output formats.
Quick routing:
All drawing types share a six-step SVG generation pipeline:
Step 1: Layout Grid Set up a coordinate system based on paper size and scale:
Paper: A1 (841x594mm at 1:50 scale -> drawing area covers 42m x 29.7m real-world)
Grid: 10mm base grid for component snapping
Margins: 20mm all sides, 50mm bottom for title block
Origin: Top-left at (20, 20)mm
Standard paper sizes:
Standard scales: 1:20, 1:50, 1:100, 1:200, 1:500, NTS (not to scale)
Step 2: Component Placement Place symbols from the symbol library at specified coordinates:
// Reference the ISA-5.1 library (from references/symbols/symbols-pid.ts)
// or IEEE library (from references/symbols/symbols-electrical.ts)
import { PID_SYMBOLS } from './references/symbols/symbols-pid.js';
import { ELEC_SYMBOLS } from './references/symbols/symbols-electrical.js';
const symbol = PID_SYMBOLS['centrifugal-pump'];
// Place at grid coordinate with optional rotation
const placed = placeSymbol(symbol, { x: 150, y: 200 }, { rotation: 0 });
Step 3: Connection Routing Route pipes and wires between components with automatic bend detection:
Step 4: Dimensions and Annotations
3" SCH 40 CS (3-inch Schedule 40 carbon steel)Step 5: Title Block Generation
import { TitleBlock } from '../../types/infrastructure.js';
const titleBlock: TitleBlock = {
projectName: 'Data Center Cooling System',
drawingNumber: 'P&ID-001',
revision: 'Rev. A',
date: '2026-02-27', // ISO 8601
drawnBy: 'Claude (AI-Assisted)',
checkedBy: 'VERIFY WITH LICENSED PE', // ALWAYS this value -- non-configurable
scale: '1:50', // or "NTS"
sheet: '1 of 3',
};
Title block occupies bottom 50mm of drawing. PE disclaimer printed in title block as non-removable text element.

Data center floor plan elements:
Coordinate system: Origin at lower-left structural column. All dimensions in millimeters. Grid on structural module (typically 600mm or 1200mm).
Isometric drawings show 3D pipe routing on a 2D plane.
Projection math:
Isometric grid point calculation:
Screen x = (real_x - real_y) * cos(30) * scale
Screen y = (real_z * scale) - (real_x + real_y) * sin(30) * scale
Where: cos(30) = 0.866, sin(30) = 0.5
Required elements:
Piping isometric conventions:
Scale selection based on system size and drawing purpose:
| System Size | Recommended Scale | Paper Size |
|---|---|---|
| Single equipment | 1:20 | A3 |
| Room/module | 1:50 | A1 |
| Floor/building | 1:100 | A1 or D |
| Campus/site | 1:200 or 1:500 | E |
| P&IDs | NTS (schematic) | A1 |
| SLDs | NTS (schematic) | A1 |
Scale annotation: Written as ratio ("1:50") in title block and as graphic scale bar on floor plans and isometrics. P&IDs and SLDs use "NTS" (not to scale) -- they are schematic, not dimensional.
