What is tag-audit-and-takeoff?

A drawing-based quantity audit for construction plans that counts individually tagged items such as fixtures, doors, devices, and equipment. It combines visual inspection and text recognition to check that tags are present and produce a traceable count.

Auditing construction drawings, reconciling visual and OCR findings, marking up sheets, checking tag completeness, and exporting count-based quantity takeoffs to Excel.

It helps find missing or overlooked tags and makes each quantity defensible by recording where the count came from. It is limited to discrete item counts, rather than measuring areas or lengths.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00054	$0.03636
Opus 5	$0.00027	$0.01818
Sonnet 5	$0.00011	$0.00727

Security

Grade A, and why

tag-audit-and-takeoff scanned grade A with 2 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 10d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/markup_tags.py, scripts/qto_to_xlsx.py, scripts/shared.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Sends data to an external URLlowData exfiltration

A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.

`curl -s -X POST '{api_url}/projects/{project_id}/graph/export' -H 'Content-Type: application/json' -d '{\"rootPath\": \"'$(pwd)'\"}'`"

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

`curl -s -X POST '{api_url}/projects/{project_id}/graph/export' -H 'Content-Type: application/json' -d '{\"rootPath\": \"'$(pwd)'\"}'`"

Tag Audit & Quantity Takeoff

Purpose

Count-based QTO for tagged construction elements — fixtures, devices, doors, equipment, and any element identified by a tag/symbol on drawings. Does NOT do area (sqft) or linear (lf) takeoffs — only discrete counts.

The QTO is a byproduct of the audit. The real value: the completeness engine that finds what's tagged, what's missing, and produces a defensible count with full provenance for every number.

Does NOT: do area/linear takeoffs, create outbound documents autonomously, override user-approved groupings, or assume quantities without provenance.

Step 0: Detect Operating Mode

Check for .construction/ directory at the project root.

AgentCM mode (.construction/ exists):

Read .construction/CLAUDE.md for project context
Read .construction/database.yaml for query_command and project_id
Sheet images at .construction/rasters/{sheet_number}.png

Verify raster images exist: Check .construction/rasters/ for PNG files. If empty, tell the user: "Raster images not found. Open this project in AgentCM to trigger the export, or run: curl -s -X POST '{api_url}/projects/{project_id}/graph/export' -H 'Content-Type: application/json' -d '{\"rootPath\": \"'$(pwd)'\"}'" You can also rasterize individual sheets on demand using the rasterize_page.py script.

OCR data queryable via extracted_items table in PostgreSQL
Write results back via API: POST /api/projects/{id}/tag-detections/ingest

Flat File mode (no .construction/):

Discover sheet images from CLAUDE.md or user-provided paths
Vision-only pipeline (Steps 2-3 skipped)
Write marked-up PNGs and QTO JSON to project directory

Step 1: User Scopes the Task

User provides: (1) tag type — e.g., "plumbing fixtures", "doors", "light fixtures" (see references/tag-types.md for full list), and (2) sheet scope — specific sheets, a discipline, or "all sheets". Confirm scope before proceeding.

Custom tag types: If the user requests a tag type not in references/tag-types.md (e.g., "keynote legends", "fire dampers", "seismic bracing"), treat it as a custom type. Use it in the tag_type field at ingest — the server auto-registers unknown types in the tag_types table with default styling. The normalized name will be qto_{type} (e.g., qto_keynote_legend). Custom types appear in the Group Review gallery and support the full accept/reject/promote workflow.

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.

tag-audit-and-takeoff is a skill published in the GitHub repository dleerdefi/claude-code-construction (37 stars, last pushed 4mo ago), licensed MIT. It adds 54 tokens to every session and 3,636 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 2 findings (sends data to an external url, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
