bid-evaluator

bid-evaluator is a skill for Claude Code, Codex from dleerdefi/claude-code-construction. It costs 42 tokens per session (1,769 once invoked), scanned A, original, MIT.

A construction-bid analysis guide for comparing tabulated subcontractor offers against project specifications and drawings. Subcontractors are specialist companies hired to perform parts of a construction project.

In plain words
What is it for?
Use it to compare prepared bids, check scope coverage, score exclusion risk, and build an award recommendation. Raw bid PDFs must be tabulated first.
Why use it?
It reveals missing work, exclusions, and risk in bids so a project engineer or manager can make a better award decision.

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.

Security

Grade A, and why

bid-evaluator 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 6d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/export_bid_evaluation.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.

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 — 211 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Bid Evaluator

Evaluate tabulated subcontractor bids against construction documents. This skill does NOT make the award decision — it builds the analytical foundation so the PE/PM can decide quickly and confidently.

Pipeline & Disambiguation

/bid-tabulator → THIS SKILL → user confirms → /subcontract-writer

This skill requires tabulated bids as input. If the user has raw bid PDFs that haven't been tabulated yet, run /bid-tabulator first to produce the per-bidder JSON files and comparison Excel. This skill consumes that output.

  • User has bid PDFs/bid-tabulator (data capture) → then offer this skill
  • User has tabulated bids and wants analysis → this skill directly
  • User says "compare bids" or "buyout" → check if bids are already tabulated; if not, start with /bid-tabulator

Tier System

  • RIGID: Output schema, scoring tables, file naming
  • GUIDED: Dialogue sequencing, scope assembly, scoring thresholds
  • FLEXIBLE: Bid interpretation, scope coverage, risk assessment

Required Inputs

  1. Tabulated bids (from /bid-tabulator or equivalent)
  2. Relevant specification sections
  3. Relevant drawing sheets (Claude reviews via vision)
  4. Scope context (from user dialogue)

Optional: bid form/ITB, schedule, owner requirements, budget estimate, past experience with bidders.


Step 1: Scope Assembly

Complete before analyzing any bids.

Mode Detection

Check for .construction/ directory at the project root.

  • AgentCM mode: Read specs from .construction/spec_text/{section}.txt. Use sheet index from .construction/index/sheet_index.yaml for drawing identification.
  • Flat File mode: Discover spec PDFs via CLAUDE.md paths or directory search (Specifications/, Specification Sections/). Read drawing sheets directly from PDF.

1a. Spec Review

Extract from each spec section: work included (Parts 1-3), work by others (GC/NIC/Owner), related section cross-references, performance requirements, coordination and temporary requirements.

What ships with it

6 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.

Changes

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.
