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 | $0.00067 | $0.02668 |
| Opus 5 | $0.00034 | $0.01334 |
| Sonnet 5 | $0.00013 | $0.00534 |
| Haiku 4.5 | $0.00007 | $0.00267 |
Grade A, and why
memstack-business-proposal-writer 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 3d 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 — 328 lines — stays where its author put it; the contents beside it link to each section on GitHub.
📝 Proposal Writer — Drafting project proposal...
Generates a professional project proposal with executive summary, deliverables, tiered pricing, timeline, and terms — ready to send as PDF or email.
Activation
When this skill activates, output:
📝 Proposal Writer — Gathering project details...
Then execute the protocol below.
| Context | Status |
|---|---|
| User says "write proposal" or "create proposal" | ACTIVE |
| User says "pitch" or "bid on project" or "client proposal" | ACTIVE |
| Preparing a document to send to a prospective client | ACTIVE |
| Writing internal project plans (no client) | DORMANT — use scope-of-work |
| Discussing pricing strategy generally | DORMANT |
Anti-patterns
| Trap | Reality Check |
|---|---|
| "Just list what we'll build" | Proposals sell outcomes, not features. Lead with the problem you solve. |
| "One price, take it or leave it" | Tiered pricing lets clients choose their budget level. Always offer 2-3 options. |
| "We'll figure out scope later" | Vague scope creates disputes. Define deliverables AND exclusions explicitly. |
| "Terms can wait until contract" | Payment schedule, revision limits, and IP ownership prevent 80% of freelance conflicts. Include them. |
| "The longer the better" | Busy clients skim. Executive summary + pricing first. Details in appendix. |
Protocol
Step 1: Gather Project Requirements
If the user hasn't provided project details, ask:
I need a few details for the proposal:
- Client name and company
- Project type (web app, mobile app, marketing site, API, etc.)
- Core problem — what does the client need solved?
- Rough scope — key features or deliverables
- Timeline — any deadlines or target launch date?
- Budget range — if known (helps calibrate tier pricing)
If the user provides partial info, ask only for what's missing. Don't ask for information you can infer.
Step 2: Write Executive Summary
The executive summary is what the client reads first (and sometimes only). It must:

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.
