Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00102 | $0.10076 |
| Opus 5 | $0.00051 | $0.05038 |
| Sonnet 5 | $0.00020 | $0.02015 |
| Haiku 4.5 | $0.00010 | $0.01008 |
Grade A, and why
building-envelope 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 11d 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.

Building Envelope
Section 1: Envelope Performance Requirements
The building envelope is the critical interface between interior and exterior environments. It must simultaneously perform four functions:
- Structural support: Transfer wind loads, dead loads (self-weight + cladding), and seismic forces to the primary structure. Resist impact loads (wind-borne debris in hurricane zones).
- Weather protection: Exclude rain, snow, wind, and UV radiation. Manage moisture in all three phases (liquid water, water vapor, ice).
- Thermal and energy performance: Control heat flow (conduction, convection, radiation), solar gain, air leakage, and condensation. The envelope accounts for 25–50% of total building energy consumption.
- Aesthetics and identity: The facade is the public face of the building. Material, proportion, texture, color, and transparency define architectural character.
1.1 Performance Metrics
| Metric | Unit | Description |
|---|---|---|
| U-value | W/m²K | Thermal transmittance (lower = better insulation) |
| R-value | m²K/W | Thermal resistance (higher = better insulation); R = 1/U |
| g-value (SHGC) | Dimensionless (0–1) | Solar heat gain coefficient — fraction of solar energy transmitted through glazing |
| VLT | % | Visible light transmittance through glazing |
| Air permeability | m³/h/m² at 50 Pa | Air leakage rate through envelope at 50 Pa pressure differential |
| Vapor resistance | MNs/g or sd (m) | Resistance to water vapor diffusion |
| Rw | dB | Weighted sound reduction index (acoustic) |
| Fire rating | Minutes/hours | Time the assembly maintains integrity and insulation in fire |
1.2 Climate-Specific Performance Targets
Hot-arid climate (ASHRAE CZ 1B–3B, e.g., Riyadh, Phoenix):
- Wall U-value: ≤0.35 W/m²K
- Roof U-value: ≤0.20 W/m²K
- Window U-value: ≤2.4 W/m²K (double glazed, solar control)
- SHGC: ≤0.25 (critical — solar rejection is primary concern)
- Shading: external shading devices essential; shading coefficient 0.3–0.5
- Thermal mass: beneficial for diurnal temperature swing damping (>300 kg/m² desirable)
- Air permeability: ≤3.0 m³/h/m² at 50 Pa (sand/dust exclusion)
- Key strategy: reject solar radiation, provide thermal mass, shade all glazing, minimize WWR to 25–35%
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

building-envelope is a skill published in the GitHub repository Abhinavbwj/Skills-Architects (285 stars, last pushed 3mo ago), licensed MIT. It adds 102 tokens to every session and 10,076 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
