Makes the skills uploadable to ChatGPT (Work mode), Claude / Cowork and Microsoft 365 Copilot, where users install a skill as a zipped folder.

Bid Leveling 4.1.0: the script is now Python, standard library only

• scripts/level.py replaces level.mjs. It uses zipfile and XML strings, with no openpyxl, no network and no installs, and runs on Python 3.8+.
• It writes the same workbook: all nine parts (sheets, styles, relationships) are byte-identical to 4.0.0's, and --json is unchanged. Python 3.12 and 3.14 produce the same bytes.
• SKILL.md fallback: if the script can't run, build the same four sheets with another spreadsheet tool, keep the formulas, and tell the user.

python3 <skill-dir>/scripts/level.py bid-data.json bid-tab.xlsx

• The tests move to test_level.py, including the byte-for-byte check of the sample workbook. A new CI step runs evals/tasks/*/test_*.py.

Descriptions capped at 200 characters

• Claude's custom-skill upload rejects descriptions over 200 characters. All four skills were 420 to 540, so every upload would have failed.
• Each description is now 193 to 199 characters and keeps its "Use to/for" triggers.
• MAX_DESCRIPTION_LENGTH is 200 in tools/skill_utils.py, with a validator test at 200 and 201 characters.
• Folder name equals name. This was already enforced.

Skill	Version
bid-leveling	4.0.0 → 4.1.0
proposal-builder	2.0.0 → 2.0.1
rfp-intake	2.0.0 → 2.0.1
workforce-planning	3.0.0 → 3.0.1
marketplace	0.10.0 → 0.11.0

Note

Rewrite bid-leveling script in Python using only the standard library

• Replaces the Node.js level.mjs script with level.py. The Python script needs only Python 3.8+ and no external packages. It validates bid-data JSON, levels bids in integer cents, suggests and applies plugs, and writes an XLSX workbook with formulas and cached values via a built-in zip/XML writer.
• Adds a full unittest suite in test_level.py covering validation, plug selection, addenda questions, workbook output, and CLI behavior. CI now runs every evals/tasks/*/test_*.py file in the validate workflow.
• Lowers the skill description limit from 1024 to 200 characters in skill_utils.py and skill-spec.md, with a new contract test. Shortened descriptions and bumped versions for bid-leveling (4.1.0), proposal-builder, rfp-intake, and workforce-planning, plus the marketplace package (0.11.0).
• Risk: MAX_DESCRIPTION_LENGTH in skill_utils.py drops from 1024 to 200, so existing skill descriptions over 200 characters now fail validation. level.mjs is deleted; any caller referencing it must switch to scripts/level.py.
