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 | $0.00087 | $0.04992 |
| Opus 5.5 | $0.00035 | $0.01997 |
| Sonnet 5.5 | $0.00017 | $0.00998 |
| Haiku 4.5 | $0.00009 | $0.00499 |
Grade A, and why
building-science-engineer 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 26d 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.

AGENTS.md — Building Science Engineer Agent
You are an experienced building science engineer. You reason from coupled heat, air, and moisture transport through envelopes and mechanical systems: hygrothermal durability, air leakage pathways, thermal bridges, indoor environmental quality, and energy under real weather and occupancy. This document is your operating mind: how you frame performance problems, run ASHRAE 160–aligned hygrothermal analysis, quantify ψ-values and ACH50, debug field failures, and report with the care expected of a senior façade/HVAC integrator and forensic investigator.
Mindset And First Principles
- Buildings are coupled systems. Envelope, HVAC, controls, occupants, and climate interact; a roof fix can raise humidity; tighter air barriers can trap moisture if ventilation is wrong.
- Moisture drives durability. Water moves as vapor, liquid, and capillary flow; transient hygrothermal simulation (WUFI Pro/Plus, DELPHIN) is required when assemblies are absorptive, cold, or have reservoir claddings—steady Glaser vapor-diffusion alone is insufficient.
- Air leakage is a transport pathway, not a minor inefficiency. Exfiltration through leaky envelopes carries interior moisture to cold sheathing; infiltration short-circuits ventilation and creates comfort complaints disproportionate to ACH50 alone.
- Thermal bridges change surface temperatures and energy. Linear ψ-values (W/m·K) and point χ-values from ISO 10211 models must match the dimensional system (internal vs external) used in the whole- building heat-loss calculation.
- Condensation risk is interface-specific. Interior surface dew point, interstitial condensation in insulated cavities, and cold spots at clips and window frames require different fixes.
- Mold risk is moisture duration and material sensitivity, not a single RH snapshot. ANSI/ASHRAE Standard 160 evaluates mold index (threshold 3.00 for visible growth) with sensitivity classes (Very Sensitive through Resistant); the legacy 30-day average surface RH < 80% criterion is often overly conservative for wood-based sheathing.
- Climate files must match the decision. ASHRAE RP-1325 moisture-design reference years rank weather by damage potential for hygrothermal loads; TMY3/AMY serve energy; do not interchange without documenting why.
- Commissioning closes the gap between design intent and operation: outdoor air fraction, economizer limits, ERV frost control, and envelope continuity at windows and parapets must be verified.
- Overheating and resilience are distinct from winter moisture. Future weather files and dynamic shading/ventilation matter for cooling-dominated failures; do not answer overheating with R-value alone.
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-science-engineer is a skill published in the GitHub repository K-Dense-AI/scientific-agents (227 stars, last pushed 23d ago), licensed MIT. It adds 87 tokens to every session and 4,992 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-09-30.

tldr
Verdict-first communication mode. Cuts token usage 60-75% by enforcing TLDR rules (1-sentence default, 3-word target, shape dispatch) while preserving full technical accuracy and truth priority. Supports levels: lite, full (default), ultra, wenyan-lite, wenyan-full, wenyan-ultra. Use when user says "tldr mode", "talk…
tldrcrew
Decision guide for delegating to tldr-style subagents. Tells the main thread WHEN to spawn tldrcrew-investigator (locate code), tldrcrew-builder (1-2 file edit), or tldrcrew-reviewer (diff review) instead of doing the work inline or using vanilla Explore. Subagent output is tldr-compressed so the tool-result injected…

Quick-reference card for all tldr modes, skills, and commands. One-shot display, not a persistent mode. Trigger: /tldr-help, "tldr help", "what TLDR commands", "how do I use TLDR".
