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 5.1 | $0.00055 | $0.01921 |
| Opus 5 | $0.00028 | $0.00960 |
| Sonnet 5 | $0.00011 | $0.00384 |
| Haiku 4.5 | $0.00006 | $0.00192 |
Grade A, and why
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 9d 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 — 126 lines — stays where its author put it; the contents beside it link to each section on GitHub.
When to use
Trigger this skill when:
- Discovery is complete and the buyer has asked for a proposal or SOW.
- A champion has requested a written document to circulate internally for budget approval.
- A deal is advancing from demo to commercial discussion and the rep needs to formalize scope.
- An RFP response has been returned and the buyer wants a more readable commercial proposal alongside it.
Do not use this for first-touch collateral or for highly prescriptive RFP responses — use rfp-responder for the latter.
Inputs
Required:
customer_name— legal entity.discovery_notes— structured or unstructured notes from discovery calls. Must include stated pain, desired outcome, and any requirements.our_proposed_solution— which product/package is being proposed, at what scale.pricing_structure— tiers or SKUs to include, with any negotiated terms.
Optional:
timeline_constraint— customer deadline (e.g. "must be live by end of Q2").competitive_context— if the customer is also evaluating a competitor.case_study_library— list of internal case studies available to cite (preferred over letting the skill invent).prior_proposal_template— if the org has a canonical proposal to pattern-match.
Outputs
A single Markdown document built from these sections (see references/proposal-template.md for the full template):
- Cover page — customer name, our company, proposal title, date, version, contacts.
- Executive Summary — 3-4 paragraphs, stands alone.
- Our Understanding of Your Situation — mirrors their words from discovery.
- Proposed Approach — mapped section-by-section to their requirements.
- Scope — in-scope, out-of-scope, clearly delimited.
- Deliverables — itemized list, each with acceptance criteria.
- Timeline — phased with milestones and dependencies.
- Investment — pricing tiers and line items.
- Assumptions — contractual prerequisites.
- Our Team — bios of the proposed delivery team.
- Case Studies — 2-3 relevant, named.
- Next Steps — concrete actions with owners and dates.
- Terms & Conditions — reference to MSA / SOW.
- Appendix — supporting materials.
What ships with it
1 file 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.
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.

proposal-writer is a skill published in the GitHub repository tahirraufkeeyu/software-development-agent-stack--sdas (18 stars, last pushed 4mo ago), licensed MIT. It adds 55 tokens to every session and 1,921 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
