Context cost

Floor Area Exemption Pitfalls loads about 1.4k tokens when it runs. Until then it costs about 141 tokens; SKILL.md has 565 words of instructions outside code blocks.

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Floor-Area Exemption Pitfalls (容積免計項目實務陷阱)

Overview

This skill captures field-level pitfalls in Taiwan's floor-area-ratio (FAR / 容積) exemption items — the practitioner know-how that statutory text omits. Plain code lists the exemption threshold; it does not warn you that a value drawn exactly at the threshold will fail at completion. Invoke this skill when:

  • Planning FAR-exempt spaces (elevator/stair lobbies, MEP rooms, etc.)
  • Deciding whether drawn clear dimensions must reserve thickness for finishing layers
  • FAR is nearly maxed out and any failed exemption causes an overage
  • Self-checking before use-permit (使照) inspection to avoid completion-stage failures

Core Principle: Nominal Drawing Dimension ≠ Finished Clear Dimension

Many FAR (and other) exemption/compliance thresholds are checked against the finished clear dimension, but drawings often note the structural / rough nominal dimension. Finishing layers consume the difference:

nominal clear dimension − two-side finishing thickness (stone, tile, substrate) = finished clear dimension (the value the regulator actually measures)

When a threshold is "greater-than-or-equal", drawing exactly at the threshold guarantees a completion-stage shortfall. The correct practice is to reserve finishing thickness as buffer and draw above the threshold.

This is a cross-regulation recurring pattern. The elevator/stair lobby FAR exemption is the most typical and highest-consequence instance — the first card in this series.


Pitfall Card: Elevator/Stair Lobby (梯廳) FAR Exemption — Finished Clear Dimension Trap

FieldValue
Regulatory basisBuilding Technical Regulations (Design & Construction) Article 162, Paragraph 1, Subparagraph 1
ThresholdThe shared stair/elevator lobby clear depth (淨深度) must be ≥ 2.0 m (note: clear depth — measured at the finished face). Also: exempt lobby area ≤ 10% of that floor's area; balcony + lobby combined ≤ 15% of that floor's area (excess counts toward FAR)
Gap mechanismnominal depth − stone-cladding/finishing thickness on both ends = finished clear depth (eroded by finishes; dropping below 2 m forfeits the exemption)
Drawing countermeasureDraw nominal 2.1 m, reserving finishing thickness (≈5 cm per side, adjust to actual build-up), so the clear depth stays ≥ 2.0 m after cladding
Failure consequencefinished face < 2.0 m → lobby area counts toward FAR gross floor area → if FAR already maxed, overage → use permit (使照) inspection fails
Failure timingSurfaces only after finishing is installed; very hard to remediate (may require demolishing finishes or altering structure)
Linked itemsFAR gross-floor-area calculation, interior fit-out, use-permit completion inspection
Severity🔴 High (directly blocks the use permit; a late-stage, post-completion risk)

Mnemonic: the 2 m threshold is what must be measurable after cladding; draw 2.1 m so the stone's thickness is given away up front.

Cross-Regulation Siblings (to be added)

The same "finishing layer / construction tolerance erodes clear dimension → crosses a critical threshold → blocked" structure recurs elsewhere. Each sibling files under its own regulatory home but reuses this card format and cross-links here:

Sibling pitfall (TBD)Likely regulatory homeThreshold direction
Accessible route / corridor clear widthAccessibility design≥ (often fails after cladding)
Stair clear width / tread depthBuilding Tech Reg (egress)≥
Driveway / parking stall clear dimensionsBuilding Tech Reg (parking)≥
Fire door / stair-lobby clearancesBuilding Tech Reg (fire egress)≥
Other FAR-exemption critical/upper limitsFAR & coverage calculationvaries

To Verify

  • Clear-depth determination for irregularly-shaped lobbies (how the "> 2 m clear depth" portion is recognized when the lobby is non-rectangular) — see National Land Management Agency interpretation (nlma 12840).
  • Article 162 §1 subparagraphs 2–3 (MEP, parking exemptions) carry separate execution interpretations to review alongside the lobby exemption.
