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 | $0.00066 | $0.00721 |
| Opus 5 | $0.00033 | $0.00360 |
| Sonnet 5 | $0.00013 | $0.00144 |
| Haiku 4.5 | $0.00007 | $0.00072 |
Grade A, and why
proposal-builder 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 4d 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 — 58 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Proposal Builder — Rainmaker
"A proposal is the call you already had, written down."
When to use
- "Write the proposal for {client}"
- "They asked for a quote"
- "Turn these call notes into an offer"
- After
call-prep+ the call itself; hand the notes over — the proposal should contain zero new ideas
Workflow
- Harvest the inputs: call notes, agreed pains, stated budget signals, decision process, deadline. Missing a pain confirmed by the client? Stop and say so — a proposal without confirmed pain is a brochure.
- Restate the problem in their words (verbatims from the call). This section wins or loses the deal.
- Design 3 options (Good/Better/Best): the middle one is the one you want them to pick; the small one makes it safe, the big one makes it look reasonable. Each option = outcome, scope bullets, what's excluded, price.
- Anchor value before price: quantify the cost of the problem or value of the outcome using THEIR numbers when given.
- Timeline & responsibilities: start date, milestones, what you need from them (the hidden deal-killer).
- Terms: validity date (7-14 days), payment schedule, the one guarantee you can honour. Flag anything for
review-contract(legal) before sending. - Close with a single next step: signature link / kickoff date / reply "option B" — one action, dated.
- Format: deliver as a clean markdown file ready for PDF/docx conversion.
Output format
## Proposal — {client} · valid until {date}
### 1. Where you are (your words) ← verbatims
### 2. Where you want to be ← outcome, quantified
### 3. Options
| | Good | Better ★ | Best |
|Outcome|...|...|...|
|Scope|...|...|...|
|Not included|...|...|...|
|Price|...|...|...|
### 4. Timeline & who does what
### 5. Terms (validity · payment · guarantee)
### 6. Next step: {one dated action}
Quality bar
- Problem section uses the client's actual words from the call
- Exactly 3 options; the target option is visibly the rational choice
- Exclusions explicit — scope creep dies here
- Price appears AFTER value, never in the first screen
- Validity date + one single next step
- Nothing promised that Legal or the product can't back
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.
- 4d ago First seen · 58 lines · 66 tokens per session scan A a8c235e962b9
proposal-builder is a skill published in the GitHub repository alebgl77/claude-inc (14 stars, last pushed yesterday), licensed MIT. It adds 66 tokens to every session and 721 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.

article-writing
Write articles, guides, blog posts, tutorials, newsletter issues, and other long-form content in a distinctive voice derived from supplied examples or brand guidance. Use when the user wants polished written content longer than a paragraph, especially when voice consistency, structure, and credibility matter.
mem0-oss-to-platform
Plan and then execute a migration of a project from the mem0 open-source / self-hosted SDK (the local Memory class) to the mem0 Platform / hosted / managed SDK (the MemoryClient class). Use this whenever a developer wants to move, switch, or migrate their mem0 usage off OSS/self-hosted to the hosted API — e.g.…
complete-partial-pr
Evaluate and complete an issue or PR where the submitted patch fixes only a narrow symptom of the reported pain point. Use when a contribution may miss adjacent integration surfaces, provider/spec semantics, roundtrip behavior, tests, docs, or historical maintainer decisions.
deploy-docker-compose
Run the Omnigent server as a Docker compose stack (server + Postgres) on any Docker host — your laptop, a VPS, EC2 by hand, or as the base layer of any container-platform deploy. Invoke when the user wants to build the image, bring up the compose stack, debug the stack on a host they already have, or extend the stack…

Maps clinical concept spans extracted by OpenMed to SNOMED CT concepts through a USER-SUPPLIED terminology server (the user's own Ontoserver, Snowstorm, or UMLS/UTS), never a bundled vocabulary. Use when the user wants to code findings, disorders, procedures, body structures, or substances to SNOMED CT, run an ECL…
