construction-lawConstruction law analysis covering FIDIC (2017 suite), PSSCOC, SIA Conditions, NEC4, and JCT.
Construction Law is an agent skill from LeoYeAI/openclaw-master-skills. Construction law analysis covering FIDIC (2017 suite), PSSCOC, SIA Conditions, NEC4, and JCT. Use when (1) analysing contract clauses, risk allocation, or obligations; (2) preparing or reviewing claims (delay, disruption, prolongation, EOT, loss & expense); (3) comparing contract forms or advising on procurement strategy; (4) drafting or reviewing notices, correspondence, or contract documents; (5) building obligations registers or notice calendars; (6) discussing dispute resolution (DAB/DAAB, adjudication…
Its SKILL.md is about 2.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 17 other files, including scripts and reference files (for example `.clawhub/origin.json`, `_meta.json` and `references/claims.md`).
It sits in Business, Finance & HR, covering Dispute resolution, Operations and SOPs and Vendor and procurement management. The repository describes itself as: 🧠 Curated collection of 1209+ best OpenClaw skills — weekly updated by MyClaw.ai. The licence is MIT.
5 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit e5199b5. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Ships 7 files in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
python3pip3From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md. Its commands use pip3, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Construction Law loads about 2.3k tokens when it runs, and up to ~16k if it reads all its reference files. Until then it costs about 223 tokens; SKILL.md has 807 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.
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); the scripts in this folder are not scanned.

All Python scripts in this skill are safe, read-only template generators.
- ✅ No network access — no API calls, no HTTP requests, no telemetry
- ✅ No subprocess execution — no shell commands, no external programs
- ✅ No filesystem traversal — only writes to the user-specified
--outputpath- ✅ Read-only static reference data — contract clauses bundled with the skill
- ✅ Verified clean: VirusTotal Benign • ClawScan Benign
The "Static analysis: Review" flag is auto-triggered because
excel_register.pyuses Python's standardimportlibto compose sibling scripts in the samescripts/folder — this is benign and intentional.Safe to install and use. 🛡️

| Form | Type | Design By | Key Feature |
|---|---|---|---|
| FIDIC Red | Measure & Pay | Employer | Employer bears quantity risk |
| FIDIC Yellow | D&B | Contractor | Single-point design + build responsibility |
| FIDIC Silver | EPC/Turnkey | Contractor | Maximum risk on contractor |
| FIDIC Gold | DBO | Contractor | Includes O&M phase |
| FIDIC Emerald | Underground | Varies | Tunnelling-specific risk sharing |
| NEC4 Option A | Activity Schedule | Varies | Lump sum with early warning mechanism |
| NEC4 Option C | Target Cost | Varies | Pain/gain sharing, Clause 10.1 good faith |
| PSSCOC | Government | Employer | Singapore public sector standard |
| SIA | Private | Employer | Singapore private sector standard |
| JCT | Various | Varies | UK standard forms |
ALWAYS ask which edition/year of the contract form. Many SG projects still use PSSCOC 2017 (7th Ed) even for new awards — don't assume the latest edition. Same applies to FIDIC (1999 vs 2017), SIA, NEC, and JCT.
Determine which standard form (or bespoke) applies. Check for amendments, particular conditions, and any deleted/modified clauses.
Common editions in active use:
For any clause question:
For delay/disruption/EOT claims, follow this structure:
Step 1 — Entitlement: Identify the contractual basis (which clause?) Step 2 — Causation: Establish cause-and-effect (what event → what delay?) Step 3 — Notice: Verify notice requirements met (time-bar compliance) Step 4 — Substantiation: Evidence and records supporting the claim Step 5 — Quantification: Calculate time/cost impact
When building notice calendars, capture:
Risk should be allocated to the party best able to:
Incorrect allocation → pricing inflation, claims escalation, disputes.
For detailed clause-by-clause analysis, load the relevant reference:

Construction law analysis covering FIDIC (2017 suite), PSSCOC, SIA Conditions, NEC4, and JCT. Construction Law is an agent skill from LeoYeAI/openclaw-master-skills. Construction law analysis covering FIDIC (2017 suite), PSSCOC, SIA Conditions, NEC4, and JCT.
Construction Law fits situations like: analysing contract clauses; risk allocation; reviewing claims (delay; loss & expense).
Run `npx skills add LeoYeAI/openclaw-master-skills --skill construction-law -a claude-code`. Or copy the skill folder (skills/construction-law in LeoYeAI/openclaw-master-skills) into .claude/skills/construction-law in your project. Claude Code loads it when a task matches its description.
Run `npx skills add LeoYeAI/openclaw-master-skills --skill construction-law -a codex`. Or copy the skill folder (skills/construction-law in LeoYeAI/openclaw-master-skills) into .agents/skills/construction-law in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add LeoYeAI/openclaw-master-skills --skill construction-law -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/construction-law, .gemini/skills/construction-law, .github/skills/construction-law and .opencode/skills/construction-law in your project.
Going by SKILL.md and its folder, Construction Law needs Python for the scripts in its folder and the command-line tools its instructions call (python3 and pip3). Our summary lists: Python 3.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
Construction Law is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 2.3k tokens (SKILL.md is roughly 9.2k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 13k tokens, read only when the agent opens those files.
Skills that share tags, products or a category with Construction Law: Master Builder (ibuilder/massing, 122 stars), Process Mapper (alirezarezvani/claude-skills, 28k stars), Business Operations Skills (alirezarezvani/claude-skills, 28k stars) and Procurement Optimizer (borghei/Claude-Skills, 891 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
LeoYeAI (a GitHub user) maintains it in LeoYeAI/openclaw-master-skills, which has 2,161 GitHub stars. The repository holds 1,235 skills in this directory. The repository was last updated on July 20, 2026.
