Pair it with pdf to read the brief or RFP you are answering, brand-review to catch voice drift before you send, and doc-coauthoring for the redline round afterwards. All four are Anthropic-published and verified on Claude.ai, so the entire workflow lives in your browser: enable them once in your account settings and then describe the proposal in a normal conversation. ## The picks ### 1. docx (Official) Anthropic's own Word skill, and the reason a proposal comes out as a document rather than a wall of chat text. It creates and edits .docx files with real formatting, tables, comments, and tracked changes — the format clients expect to receive and mark up. - Reach for it when: The deliverable is a Word document a client will open, comment on, and send back. - You end up with: A formatted .docx proposal you download from the conversation. - Entry: https://top-agent-skills.com/skill/docx (https://top-agent-skills.com/skill/docx.md) ### 2. pdf (Official) Most proposals answer something: an RFP, a scope document, a filled-in intake form. This extracts the text and tables from those PDFs so the requirements go into the draft accurately instead of being retyped from a skim. - Reach for it when: You were sent a PDF brief, RFP, or contract and the proposal has to respond to what it actually says. - You end up with: Structured text and tables pulled out of the source PDF. - Entry: https://top-agent-skills.com/skill/pdf (https://top-agent-skills.com/skill/pdf.md) ### 3. brand-review (Official) Reviews a draft against your brand voice, style guide, and messaging pillars and flags deviations by severity with specific before/after fixes. It is the step that keeps a fast draft from sounding like it was written by someone who does not work at your company. - Reach for it when: Before the proposal goes out — especially when a contractor or a fast first draft wrote it. - You end up with: A severity-tagged list of voice and messaging fixes, each with the rewrite. - Entry: https://top-agent-skills.com/skill/brand-review (https://top-agent-skills.com/skill/brand-review.md) ### 4. doc-coauthoring (Official) Handles the round after the send: multi-author editing with track changes, suggestion mode, and conflict resolution, so the agent behaves like one reviewer among several rather than overwriting everyone. - Reach for it when: The proposal is being redlined by a client, a partner, or your own team at the same time. - You end up with: A revised document with tracked suggestions rather than silent rewrites. - Entry: https://top-agent-skills.com/skill/doc-coauthoring (https://top-agent-skills.com/skill/doc-coauthoring.md) ## What these Skills will not do - They draft and format; they do not send. Nothing here emails the proposal, signs it, or pushes it into a CRM or e-signature tool. - Skills on Claude.ai run in a server-side sandbox with no shell and no access to your computer’s files. You upload what it should read and download what it produces. - brand-review checks a draft against the voice and messaging rules you give it. It has no knowledge of your brand until you provide the guide or examples. - Pricing and pipeline logic are yours. A proposal skill will happily format a number you got wrong. ## Common questions **What is the best AI skill for writing client proposals?** docx, Anthropic’s Word skill. It creates and edits real .docx files with formatting, tables, comments, and tracked changes, so the output is a document a client can open and redline rather than text in a chat window. Add pdf if you are responding to an RFP, and brand-review as the final voice check. **Do I need to be technical to use these?** No. Installing a Skill on Claude.ai is a file upload in your account settings — download the skill folder, zip it, upload it under Customize → Skills. There is no terminal, no command line, and no code. After that you describe the proposal in plain language and the Skill loads itself when it matches the request. **Can Claude read the RFP PDF a client sent me?** Yes, that is what the pdf skill is for. It extracts text and tables from PDFs, including filled forms, so the requirements go into your draft accurately instead of being retyped from a quick read. Upload the PDF to the conversation and ask for the requirements pulled out. **Will the proposal sound like a template?** That is the risk these four are arranged to manage. docx handles structure and formatting, and brand-review then checks the draft against your own voice, style guide, and messaging pillars and returns severity-tagged before/after fixes. The quality of that check depends entirely on the brand material you feed it. **How much does this cost?** Every Skill listed here is free and MIT-licensed; what you pay for is the Claude plan that runs them. Anthropic’s help centre lists Skills as available on Free, Pro, Max, Team, and Enterprise plans, and they require "Code execution and file creation" to be enabled under Settings → Capabilities. Check the support article for the current plan details before budgeting around it. --- _Top Agent Skills.
