Construction agent skills

28 installable skills for Claude Code, Claude apps and any agent that reads a SKILL.md

Estimating · architecture · visualisation · engineering · scheduling · site operations · safety · commercial · business development

Install

Claude Code — as a plugin (recommended: updates come with a pull):

/plugin marketplace add constructelligence-lab/construction-agent-skills
/plugin install construction@construction-skills

Claude Code — as plain skills, if you would rather keep them in your own folder:

git clone https://github.com/constructelligence-lab/construction-agent-skills.git
mkdir -p ~/.claude/skills
cp -r construction-agent-skills/skills/* ~/.claude/skills/

Copy only the skills you want — each folder is independent, and nothing here needs a build step or a dependency. For a project-scoped install, copy the same folders into .claude/skills/ inside the repository you are working in.

Claude apps and other agents. Zip the skills/ folder and upload it wherever your tool accepts skills, or point your agent at the SKILL.md files directly — the format is plain Markdown with front-matter, so nothing here is tied to one vendor.

What is in it

Preconstruction

Qualifying work, framing the programme, finding risk before you price it.

Skill	Use it when	Tags
Bid qualification: go or no-go bid-go-no-go	An invitation to bid lands and you need a defensible recommendation before you spend a week estimating it.	bidding risk preconstruction
Constructability risk review of a drawing set constructability-risk-review	You are pricing or planning a job and want a structured list of buildability questions before the bid goes in.	preconstruction drawings risk
Programme and sequencing options programme-and-sequencing-options	You have a target completion date and a rough scope, and you want the plausible sequencing options on the table before you build a CPM schedule.	preconstruction programme sequencing

Estimating and takeoff

Sanity checks, pricing narratives and takeoff review.

Skill	Use it when	Tags
Unit rate sanity check unit-rate-sanity-check	An estimate is nearly finished and you want a second pair of eyes on whether the rates and quantities hang together — before the bid goes in, not after.	estimating pricing review
Takeoff review checklist takeoff-review-checklist	A takeoff has been produced — by a person, by software, or by one of the tools in our open source construction tools list — and it needs a review that is actually systematic.	takeoff quantities quality
Change order pricing narrative change-order-pricing-narrative	The numbers are agreed internally and now need to be presented so they are hard to argue with — typically for a priced change that a client or a subcontractor will scrutinise.	change-orders commercial pricing
Productivity assumption stress test productivity-assumption-stress-test	An estimate depends on production rates you have assumed rather than measured, and you want to know how much of the margin is riding on them.	productivity labour risk

Architecture and design

Briefs, specifications, code topics and design review.

Skill	Use it when	Tags
Design brief from a client conversation design-brief-from-conversation	You have come out of a client meeting with scattered notes and need a written brief that the client can confirm or correct before design work starts.	brief client architecture
Specification section draft specification-section-draft	You need a first draft of a specification section structure so you are editing rather than staring at an empty document — with the understanding that the technical content is yours, not the model's.	specification documentation quality
Code and accessibility checklist for a design review code-and-accessibility-checklist	You want a structured set of compliance questions to work through for a design, recognising that the model does not know your local code and must not be treated as knowing it.	code accessibility compliance
Design review agenda that finds problems design-review-agenda	You are running a design or coordination review and want an agenda that surfaces conflicts rather than walking through the drawings in order.	coordination meetings design

Visualisation and rendering

Image prompts, iteration and critique before a client sees it.

Skill	Use it when	Tags
Photorealistic exterior render prompt photorealistic-exterior-render	You need a client-ready exterior visual quickly, before the model is advanced enough for a proper render, or to explore a façade direction.	rendering visualisation marketing
Interior render: iteration prompt interior-render-iteration	The first interior image is close but wrong — the light, the proportions or the materials — and you want to change one thing at a time rather than regenerate from scratch.	rendering interior iteration
Render critique before it goes to the client render-critique-before-client	You are about to send a visual to a client and want a hard critique first — one that finds the things an architect, a planner or a contractor would spot immediately.	rendering review presentation

Engineering

Structural and MEP sense checks, with an engineer and never instead of one.

Skill	Use it when	Tags
Structural load path sanity check load-path-sanity-check	You are preparing for a coordination or value-engineering discussion and want the obvious load path and stability questions on the table.	structure review engineering
MEP coordination and clash triage mep-coordination-clash-triage	You have a clash report or a coordination problem list and need to decide which clashes matter, in what order to resolve them, and who should move.	mep coordination bim

Scheduling and planning

Narratives, look-aheads and the records a delay claim is built from.

Skill	Use it when	Tags
Schedule narrative for the owner schedule-narrative-for-owner	The monthly schedule update is done and needs the narrative section: what moved, why, what you are doing about it, and what you need — without excuses and without jargon.	schedule reporting communication
Three-week lookahead constraint sweep lookahead-constraint-sweep	You are building the next three-week lookahead and want to remove constraints before they stop work, rather than reporting them after the fact.	lookahead field planning

Site and field operations

Turning field notes into records somebody can act on.

Skill	Use it when	Tags
Daily report from messy field notes daily-report-from-notes	The day's notes are a mix of texts, voice-note reminders and scribbles, and the report needs to be written before you go home — with the facts intact and nothing invented.	field records daily-report
RFI drafting that gets answered rfi-drafting	Something on site does not match the drawings and you need an RFI that is clear enough to be answered first time, with the schedule impact stated.	rfi documents coordination

Safety and compliance

Task-specific safety documents, written with a competent person.

Skill	Use it when	Tags
Job safety analysis from a task description jsha-from-task-description	You are preparing a task-specific safety analysis and want a structured first draft to edit with the crew, rather than starting from a template that says nothing about this job.	safety jsha field
Toolbox talk from a real near miss toolbox-talk-from-near-miss	Something nearly went wrong on this site and you want a five-minute talk that lands with the crew, rather than a generic briefing they have heard ten times.	safety training briefing

Contracts and commercial

Notices, risk reviews and payment narratives, drafted for review.

Skill	Use it when	Tags
Contract risk review preparation contract-risk-review	A contract or subcontract is on your desk and you want the risk topics organised before it goes to your lawyer, so the expensive hours are spent on judgement rather than on reading out loud.	contracts risk commercial
Notice letter draft notice-letter-draft	An event has occurred and the contract requires written notice.	notices claims correspondence

Business development

Case studies, proposals and the writing that wins the next job.

Skill	Use it when	Tags
Project case study from the facts case-study-from-facts	You have finished a job worth writing about and need a case study for the website, a proposal or a prequalification pack — without inventing anything and without breaching confidentiality.	marketing case-study bd
Tailoring a proposal to the client's actual concerns proposal-tailoring	You have a standard proposal structure and a specific client, and you want the document to answer what they are worried about instead of repeating your company history.	proposals bidding bd

Automation and analysis

For the person who would rather script it than retype it.

Skill	Use it when	Tags
IFC data extraction script ifc-data-extraction-script	You need a repeatable way to pull data out of IFC models — quantities, spaces, properties — instead of clicking through them, and you would rather review code than write the boilerplate.	ifc bim python automation
Job cost analysis in Python or pandas job-cost-analysis-in-python	Your accounting system will give you a job cost export but not the analysis you want, and the work is repetitive enough to script rather than rebuild in a spreadsheet every month.	job-cost python analysis automation

Anatomy of a skill

Every skill has the same five parts, so you can edit any of them without relearning the shape:

Part	Why it is there
name and description in the front-matter	The description is the only text loaded before a skill matches, so it carries the trigger words. If it is vague, the skill is never used
Inputs to collect	The variables the agent must ask for, which is what stops it inventing a project size, a rate or a clause reference
Instructions	The procedure and the output format, in order
What good output looks like	How to tell a useful answer from a fluent one
Follow-ups and Guardrails	How to sharpen the answer, what never gets pasted in, and which professional signs it off

Coverage

How this library was built

The skills were generated from the construction prompts library and then given skill front-matter, input lists and guardrails. That keeps one source of truth for the instructions and makes it cheap to keep both libraries in step:

python3 scripts/import_prompts.py --source ../construction-prompts/prompts   # regenerate skills
python3 scripts/build_index.py                                              # rebuild the index and badge
python3 scripts/validate.py                                                 # check them

CI runs the build and the validator on every push, and fails if the index in this README has drifted from the files — so the tables above cannot quietly go stale.

Ground rules

• A person owns every output. These skills produce drafts. Nothing goes to a client, an owner, a subcontractor or a regulator without a named reviewer.
• Never paste contracts under negotiation, pricing or bid strategy, personal or medical data, anything under an NDA, or anything a client has asked you to protect.
• Verify anything factual — quantities, dates, clause references, code sections and figures — against the source document.
• Use a business tier with terms that exclude your data from model training, and a written company rule on what may be pasted. Skills do not change what your AI tool does with your data; your tool's terms do.
• Professional work stays professional. Structural and MEP skills are sense checks, not calculations. Safety skills are written with a competent person. Commercial skills are drafted for your lawyer to review, not instead of it.

Contributing

Add a folder under skills/<name>/SKILL.md, then run the build and the validator. A useful skill says where it came from — a real job, a real failure mode — and what it is bad at. Skills that only sound impressive do not belong here.
