What it does

Oce Load Cost Bases is an agent skill from datadrivenconstruction/DDC_Skills_for_AI_Agents_in_Construction. Load national and market cost bases into OpenConstructionERP: the 8 national bases (Turkey Birim Fiyat, China Dinge, Brazil SINAPI, Spain BCCA, Italy Prezzario Toscana, Greece GGDE, Vietnam Dinh Muc, Indonesia AHSP), the 30 global markets, and 48 PPP market catalogs per base. Use when importing a cost database, repricing into a market, or troubleshooting a load.

Its SKILL.md is about 850 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

  • Importing a cost database
  • Repricing into a market
  • Troubleshooting a load

Example prompts

  • “/oce-load-cost-bases”

Workflow steps

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

  1. Pick a market card from GET /api/v1/costs/base-catalog (e.g. TR_NATIONAL:DE_BERLIN_de).
  2. The platform downloads the market's DDC_CWICR_DE_BERLIN_de_Catalog.csv (resources already PPP-repriced to EUR and translated to German).
  3. It re-prices the base region's resource price sheet in place — text follows the language, price follows the market.

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 http).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    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

Oce Load Cost Bases loads about 846 tokens when it runs. Until then it costs about 96 tokens; SKILL.md has 304 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~96
When it runs · the whole SKILL.md, loaded when a task matches
~846

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.

Load Cost Bases into OpenConstructionERP

The catalog of bases (2026)

National bases ship a 95-column parquet each plus 26 language editions and a markets/ folder of 48 PPP-repriced resource catalogs.

Load a base (API)

http
POST /api/v1/costs/load-cwicr/TR_NATIONAL
  • Reads the parquet (local WORLD_COST_BASES, cache, bundled dir, then GitHub download fallback).
  • Groups rows by rate_code (one row per work item, components[] inline).
  • Idempotent on (code, region): second call → {"status": "already_loaded", ...}.
  • After load, the backend swaps the region's text to the base's home language parquet (TR___DDC_CWICR/TR_tr_...), so a Turkish user sees Turkish.
Verify the load
http
GET /api/v1/costs/regions/stats/      # item count per region
GET /api/v1/costs/?region=TR_NATIONAL&limit=5   # check currency and descriptions
GET /api/v1/costs/{id}                # components[] = labour/material/machine lines
GET /api/v1/costs/category-tree/?region=TR_NATIONAL

Import the resource catalog

http
POST /api/v1/catalog/import/TR_NATIONAL

Reads DDC_CWICR_TR_Catalog.csv (resource_code, name, type, category, unit, price_avg, price_min, price_max, currency, usage_count + parent_* classification preserved in specifications).

Reprice a base into a market (PPP)

  1. Pick a market card from GET /api/v1/costs/base-catalog (e.g. TR_NATIONAL:DE_BERLIN_de).
  2. The platform downloads the market's DDC_CWICR_DE_BERLIN_de_Catalog.csv (resources already PPP-repriced to EUR and translated to German).
  3. It re-prices the base region's resource price sheet in place — text follows the language, price follows the market.

Troubleshooting

  • 404 "not found" → no local parquet and GitHub download failed; check ~/.openestimator/cache/{db_id}.parquet and network.
  • Empty currency → region missing from the currency map; add it to cwicr_v3_catalogue.py / _REGION_CURRENCY.
  • Coefficient base shows rate 0 → expected for VN/ID; seed prices via ResourcePriceService.seed_region.
  • Duplicate rows → importer collapses by (code, region); multiple price layers per code keep the first.
