View Inventory Reorder Point SkillBid Leveling Skill
The low bid usually isn't the low bid once you plug what it left out. Level every bid to the same scope, see who is really lowest, and send each bidder the right questions.
What it catches
| Situation | Code | Level |
|---|---|---|
| Stated total doesn't match the priced lines | bid_total_mismatch | error |
| Gap with no other bid or estimate to plug it | unpluggable_gap | error |
| Item missing or marked not bid (plugged) | missing_scope | warning |
| Item excluded (plugged) | excluded_scope | warning |
| Allowance under 75% of the typical price | low_allowance | warning |
| Price under 50% of typical: scope gap? | price_outlier_low | warning |
| Same item listed twice | duplicate_line | warning |
| Price over 150% of typical | price_outlier_high | info |
| Alternate or item not in the scope list | item_not_in_scope | info |
| Low bidder changes after leveling | low_bidder_changed | info |
Proven on a labeled example
examples/riverside-clinic-electrical/ is a fictional clinic fit-out electrical package: an 8-item scope with estimates and 3 bids written the way subs write them ("Rough-in & branch wiring" vs "Rough-in and branch wiring"), with a fire alarm exclusion, temp power not bid, a thin fixture allowance, a 4,800 fire alarm price, a rock-clause trenching price, an add alternate and a total that's 1,000 off. expected.json labels the leveled totals: the low base bid (Apex 119,400) becomes second at 138,900 and BrightLine wins at 129,900. The tests assert that in any row order and for each plug method.
What you get
Outputs in out/: bidders.csv (base, plugs, leveled total, rank), leveling_matrix.csv (items x bidders, plugs marked), findings.csv, report.md (with questions per bidder), summary.json. Exit 0 = ready to compare; 1 = errors to resolve; 2 = an input problem.
Quick start
./run_tests.sh
python3 -m bidlevel --bids examples/riverside-clinic-electrical/bids.csv --scope examples/riverside-clinic-electrical/scope.csv \
--totals examples/riverside-clinic-electrical/bid_totals.csv --name "Riverside Clinic - Electrical" --out out/Inputs
- Bids CSV, one row per bidder per item: Bidder, Item, Amount, Status (Included, Excluded, Allowance, Not bid, Alternate; blank with an amount = included), Note.
- Optional scope list CSV (Item, Estimate) and stated totals CSV (Bidder, Bid Total). Item names are matched ignoring case, punctuation and & vs and.
Use it from your agent
- Claude Code plugin: this folder is a plugin (.claude-plugin/plugin.json). Try it with claude --plugin-dir ./bid-leveling-skill, or add the folder to your own plugin marketplace.
- Skill only: copy skills/bid-leveling/ into ~/.claude/skills/ (or your agent's skills folder) and keep this folder where the agent can run python3 -m bidlevel.
- No agent: the CLI works on its own; --help lists every flag.
Honest limits
- Plugs are for comparison, not prices; confirm scope with each bidder before award.
- One trade package per run; items must be named consistently enough to match (map them in the CSV if not).
- It doesn't read PDFs; put each bid's lines in the CSV (an agent can do that from the proposal).
- Qualifications like schedule, bonding and insurance aren't scored.
Requirements
Python 3.9+ (tested on 3.10 and 3.13), no dependencies.
