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 | $0.00050 | $0.02435 |
| Opus 5 | $0.00025 | $0.01218 |
| Sonnet 5 | $0.00010 | $0.00487 |
| Haiku 4.5 | $0.00005 | $0.00244 |
Grade A, and why
bid-tabulator 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 5d 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 — 213 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Bid Tabulator
Processes multiple subcontractor bid PDFs for a scope of work and produces an Excel comparison workbook. Extracts each bid's data as-submitted — the engineer handles normalization and alignment after reviewing discrepancies and contacting subcontractors as needed.
RIGID Rules (non-negotiable)
- Complete extraction — zero tolerance on omission. If a bid contains data that fits ANY field in the schema, extract it. When in doubt, extract it. Extra data can be filtered; missing data cannot be recovered.
- Every page of every bid. Process ALL pages — do not stop at the first page or summary page. Bids over 10 pages contain detailed breakdowns, alternates, and qualifications that MUST be captured.
- Numeric verification. After extracting each bid, verify: (a) line item amounts sum to the stated subtotal, (b) subtotal + alternates/adjustments = base bid total. Flag any mismatch as
[MATH ERROR: line items sum to $X, bid states $Y]. - Formulas in Excel, not hardcoded values. Subtotals use SUM formulas. Reconciliation uses difference formulas. The Comparison Summary uses cross-sheet formula references to per-bidder tabs. Never paste calculated values — the engineer must be able to trace every number.
- Preserve original language verbatim. Line item descriptions, exclusions, qualifications, and notes are extracted exactly as written. No paraphrasing, normalization, or cleanup.
Step 1: Gather Inputs
Ask the user for:
- Bid PDFs — folder path or list of individual files
- Scope description — what trade/division is being bought out (e.g., "Division 09 - Finishes", "Structural Steel")
- Any specific data points the user wants extracted beyond the defaults
If project context is available (.construction/ directory), read project.yaml for project name/number to include in the workbook header.
Pipeline Position
THIS SKILL → /bid-evaluator → user confirms → /subcontract-writer
This skill is the entry point of the bid pipeline. It produces the tabulated data that /bid-evaluator consumes for analysis.
What ships with it
3 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.

bid-tabulator is a skill published in the GitHub repository dleerdefi/claude-code-construction (36 stars, last pushed 4mo ago), licensed MIT. It adds 50 tokens to every session and 2,435 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.
