What it does

Material Passports Circular is an agent skill from datadrivenconstruction/DDC_Skills_for_AI_Agents_in_Construction. Material passports and circular construction: generate per-element material inventories from BOQ/BIM, mark reuse potential and recycled content, and prepare deconstruction data. Use for circular-economy and EU Taxonomy-aligned projects.

Its SKILL.md is about 630 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: 221 AI skills for construction: BIM analysis, cost estimation, scheduling, document control, and automation with Claude Code. The licence is MIT.

When your agent uses it

Circular-economy and EU Taxonomy-aligned projects

Example prompts

“/material-passports-circular”

Requirements

Python 3

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

Prefer mechanical fixings over wet trades (plaster/glue) at interfaces.
Mark structural vs non-structural layers — non-structural is the reuse pool.
One material per composite where possible (separate insulation from structure).
Record as-built changes — the passport must match the building, not the drawing.

What it can do on your machine

Read from SKILL.md and the folder at commit ce45bbf. It shows what the files ask for, not the result of running them.

Tool permissions
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.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are python).
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
- environment.ec.europa.eu
- madaster.com
- eco-platform.org
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Material Passports Circular loads about 634 tokens when it runs. Until then it costs about 66 tokens; SKILL.md has 194 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~66
When it runs · the whole SKILL.md, loaded when a task matches: ~634

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.

Safety

Auto-check passed

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); files beside SKILL.md are not scanned.

Material Passports & Circular Construction (2026)

Why it matters

The EU Taxonomy and CSRD push construction toward circularity: buildings must be designed for disassembly, materials traceable for reuse. A material passport is a digital record of what is in a building, where, and how it can be reused at end of life.

What a passport contains

Per element (or per BOQ line):

Field	Source
material & volume/mass	BOQ components[] (`resource_name`, `resource_quantity`, `resource_unit`)
location in the building	BIM element link
manufacturer / EPD	procurement records
recycled content %	supplier declaration / EPD
reuse potential at EOL	disassembly class (reusable / recyclable / downcyclable / landfill)
embodied carbon (A1–A3)	`embodied-carbon-esg` skill

Building the passport from DDC data

python

# per BOQ line: material inventory from CWICR components
for line in boq:
    for comp in line["components"]:
        if comp["type"] == "material":
            passport.append({
                "element": line["description"],
                "material": comp["name"],
                "quantity": line_quantity * comp["quantity"],
                "unit": comp["unit"],
                "recycled_content": epd_lookup(comp["name"]),   # from EPD library
                "reuse_class": disassembly_class(comp["name"]),  # rule-based
            })

Design-for-disassembly rules to encode

Prefer mechanical fixings over wet trades (plaster/glue) at interfaces.
Mark structural vs non-structural layers — non-structural is the reuse pool.
One material per composite where possible (separate insulation from structure).
Record as-built changes — the passport must match the building, not the drawing.

Reporting

Total mass per material family (concrete, steel, timber, glass, insulation…).
% recyclable/reusable by mass (EU Taxonomy circularity KPI).
Hazardous content register (asbestos-free declaration, formaldehyde, VOC).
