Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00056 | $0.01551 |
| Opus 5 | $0.00028 | $0.00776 |
| Sonnet 5 | $0.00011 | $0.00310 |
| Haiku 4.5 | $0.00006 | $0.00155 |
Grade A, and why
sheet-splitter scanned grade A with 0 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 4d ago.
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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 154 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Sheet Splitter
Splits a bound drawing set PDF into individual page PDFs. Mirrors what spec-splitter does for specifications.
Pipeline Position
Run after /project-setup identifies bound drawing sets. Produces split PDFs and sheet_index.yaml consumed by /schedule-extractor and all drawing analysis skills.
This is valuable for:
- Project teams: Navigate drawings by sheet number instead of scrolling a multi-page PDF
- Other skills:
sheet-index-builder,drawing-reader, and all drawing analysis skills work better with individual sheet files - AgentCM: Split files become the basis for per-sheet structured data
Workflow
Sheet Split Progress:
- [ ] Step 1: Check if drawings are already split
- [ ] Step 2: Locate the bound drawing set
- [ ] Step 3: Split into individual page PDFs
- [ ] Step 4: Extract sheet numbers from title blocks
- [ ] Step 5: Rename files with sheet number + title
- [ ] Step 6: Update project context
- [ ] Step 7: Write graph entry (AgentCM only)
Step 1: Check if Drawings Are Already Split
Look for individual sheet PDFs. Drawings are already split if:
- AgentCM:
.construction/index/sheet_index.yamlexists with individual sheet entries and file paths point to split PDFs - Multiple PDFs exist with sheet number patterns in filenames (e.g.,
A-1.1 - FLOOR PLAN.pdf) - A
sheet_index.yamlexists in the drawings directory
If already split, report the count and skip. If AgentCM has the sheet index but files haven't been physically split on disk, offer to split using the existing metadata for naming.
Step 2: Find ALL Drawing PDFs
Search the project directory for ALL PDFs that are drawings. Many projects have multiple drawing PDFs:
- Multi-part sets: Part1.pdf, Part2.pdf, Part3.pdf (split by file size)
- Discipline sets: Architectural.pdf, Civil.pdf, Electrical.pdf, Mechanical.pdf
- Single combined: one large PDF with all sheets
Search in:
- Folders named
drawings/,plans/,01 - Drawings/, or similar (case-insensitive) - The project root (some projects have no folder structure)
- Look for PDFs > 2MB with keywords: "plan", "drawing", "bid set", "dwg", discipline names
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

sheet-splitter is a skill published in the GitHub repository dleerdefi/claude-code-construction (35 stars, last pushed 4mo ago), licensed MIT. It adds 56 tokens to every session and 1,551 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
