Skills are instruction files that teach Claude how to query government APIs, follow decision frameworks, and produce structured documents. No special syntax needed.

⚠ Turn these on in Claude settings first
Generate memory from chat history Allows Claude to remember relevant context from your chats and projects. Required so Claude can hold onto your API keys across conversations (step 3 below).
Cloud code execution and file creation Lets Claude execute code on a server and create and edit docs, spreadsheets, presentations, PDFs, and data reports. Required for skills to run and for the document-generating tools like SOW/PWS Builder and IGCE Builder Suite.
1
Install a skill
Unzip the download, then Customize > Skills > + > Create skill > Upload a skill > drag in each SKILL.md file individually. For skills with a reference companion, install both.
2
Register API keys (if needed)
Three free keys cover everything. BLS key from data.bls.gov (500 queries/day). api.data.gov key (1,000 req/hr, covers Per Diem + Regulations.gov). SAM.gov key from SAM.gov (covers entity lookups, exclusions + opportunities).
3
Tell Claude your keys
Say "Remember my BLS API key is [key]" and Claude stores it for future conversations automatically.
4
Ask a question
Just ask naturally. If the skill is relevant, Claude reads the instructions and makes the API call. You don't need to know how the API works.

These skills work on any Claude plan, but performance scales with what you're paying for.

Free Works for single-skill lookups. Shorter outputs, occasional refusals on complex prompts.
Pro Meaningfully better output quality, context handling, and willingness to run longer workflows without truncating.
Sonnet Fast and reliable for single-skill lookups and straightforward queries.
Opus Strongly recommended for orchestration skills that run multi-step analysis across several APIs. Use this for the SOW/PWS Builder, IGCE Builder Suite, Market Research Builder, Grants Builder, and Vendor Intelligence.
⚙ Troubleshooting
Skill not triggering? Make sure each SKILL.md file is uploaded individually under Customize > Skills. For skills with reference companions, install both.
API errors? Your agency network may block outbound API calls. Try a personal connection. This is a network policy issue, not a skill bug.
Key not working? Tell Claude your key again in the current conversation. Keys are stored in memory and carry forward automatically.
Truncated output? Switch to Opus on a Pro plan. Orchestration skills need the larger context window for full-length deliverables.

Architecture

How they connect

Orchestration skills pull from live API data sources. The SOW/PWS drives scope, the IGCE builders price it. OT skills do the same for prototype agreements outside the FAR.

What these tools won't do

Every skill in this collection follows one rule: assemble data, structure the document, leave the judgment to the human. Dozens of potential capabilities were evaluated and several were intentionally left out. The full reasoning is in AI-BOUNDARIES.md on GitHub.

✕
Proposal Evaluation Scoring
FAR 15.305 assigns evaluation to qualified panel members. AI-generated ratings would not survive GAO protest scrutiny.
✕
Best Value Tradeoff
Comparing technical merit against price across offerors is the CO's warrant authority under FAR 15.101-1. Not delegable to an algorithm.
✕
Responsibility Determinations
Assembling vendor data (registration, exclusions, award history, risk indicators) is appropriate. Declaring an entity responsible or not responsible is a CO decision under FAR 9.104-1. These tools build the dossier, not the verdict.
✕
Past Performance Ratings
CPARS is controlled-access. Performance ratings require context no public API can provide. An AI evaluator cannot testify to the basis of its assessment.
✕
Negotiation Strategy
Insulting to experienced COs, dangerous for inexperienced ones. These tools provide market data for prep. The table is yours.
✕
OCI Determinations
FAR 9.5 analysis requires legal interpretation and fact-specific inquiry. Public data can surface relationships worth investigating, not make the call.
✕
Protest Risk Prediction
Creates perverse incentives. COs would avoid legitimate actions because an algorithm flagged them. Protest drivers are non-public.
✕
Debarment Recommendations
Quasi-judicial action under FAR 9.4 with due process requirements. Pattern matching is not investigation.
✕
Contract Type Recommender
FAR 16.104 factors are subjective and context-dependent. The tools present the factors. The CO weights them.
✕
Set-Aside Decision Engine
Politically sensitive across every stakeholder group. Set-aside analysis stays embedded in Market Research where it has full context.

A tool that says "here is the data" is an accelerator. A tool that says "here is what you should do" is a replacement. Every skill in this collection is the first kind.
