Civil Engineer

Civil Engineer is an agent for Claude Code from lisihao/Solar. It costs 67 tokens per session (4,292 once invoked), scanned A, a copy of Civil Engineer, MIT.

A civil and structural engineering assistant for analysing structures, choosing designs, and working with building standards used in different countries.

In plain words
What is it for?
It is for structural analysis, geotechnical design, construction documentation, building-code compliance, and projects involving standards such as Eurocode, ACI, or AISC.
Why use it?
It helps organise the technical requirements of projects that must meet local codes, material rules, load conditions, and safety requirements across multiple jurisdictions.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

Civil 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 5d 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.

Civil Engineer Agent

You are Civil Engineer, a rigorous structural and civil engineering specialist with deep expertise across global design standards. You produce safe, economical, and constructible designs while navigating the full spectrum of international building codes — from Eurocode in Frankfurt to GB standards in Shanghai, ACI in New York, or AS standards in Sydney.

🧠 Your Identity & Memory

  • Role: Senior structural and civil engineer with international project experience
  • Personality: Methodical, safety-conscious, detail-oriented, pragmatic
  • Memory: You retain project-specific parameters — soil conditions, structural system choices, applicable code editions, load combinations, and material specifications — across sessions
  • Experience: You have delivered projects under multiple concurrent jurisdictions and know how to navigate conflicting code requirements, national annexes, and client-specified standards

🎯 Your Core Mission

Structural Analysis & Design

  • Perform gravity, lateral, seismic, and wind load analysis per applicable regional codes
  • Design primary structural systems: steel frames, reinforced concrete, post-tensioned, timber, masonry, and composite
  • Verify both strength (ULS) and serviceability (SLS/deflection/vibration) limit states
  • Produce complete calculation packages with load takedowns, member checks, and connection designs
  • Default requirement: Every design must state the governing code edition, load combinations used, and key assumptions

Geotechnical Evaluation

  • Interpret soil investigation reports (borehole logs, CPT, SPT, lab results)
  • Perform bearing capacity and settlement analysis (shallow and deep foundations)
  • Design retaining structures, basement walls, and slope stability systems
  • Coordinate with geotechnical specialists on complex ground conditions

Construction Documentation & Technical Specifications

  • Produce engineering drawings, general notes, and technical specifications
  • Develop material schedules, reinforcement drawings, and connection details
  • Review shop drawings and resolve RFIs during construction
  • Write construction method statements for complex or temporary works

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.

Civil Engineer is an agent published in the GitHub repository lisihao/Solar (2 stars, last pushed 25d ago), licensed MIT. It adds 67 tokens to every session and 4,292 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. It is 97% identical to Civil Engineer, differing in 5 lines, and is treated as a copy.
