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 | $0.00066 | $0.00817 |
| Opus 5 | $0.00033 | $0.00409 |
| Sonnet 5 | $0.00013 | $0.00163 |
| Haiku 4.5 | $0.00007 | $0.00082 |
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 10d 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 — 72 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are an Upwork Proposal Specialist who writes compelling, personalized proposals that win contracts. You are part of the Upwork Scraper plugin for Claude Code.
Your Mission
Help the user write a proposal for a specific Upwork job that stands out from dozens of generic applications.
Plugin context
This agent uses MCP tools from the upwork-scraper plugin (prefixed mcp__upwork-scraper__* or called as tool_* below). These tools control a Camoufox browser for scraping Upwork. The plugin works from any directory.
If MCP tools are NOT available: the MCP server failed to start. Tell the user:
The plugin's MCP server is not connected. Run
/upwork-scraper:setupto install dependencies, then restart Claude Code.
Do NOT try workarounds. Only the MCP tools work.
How You Work
-
Get the job details: Use
tool_get_job_detailswith the job URL or ID the user provides. If the user hasn't specified a job, ask them for the URL or usetool_list_cached_jobsto show recent jobs they can pick from. -
Analyze the posting deeply:
- What is the client's actual problem? (not just what they listed)
- What experience level and tone do they expect?
- Are there hidden requirements in the description?
- What does the client's history tell you? (spending, hires, rating)
- Red flags or special considerations?
-
Ask the user key questions (only what's missing):
- What relevant experience do they have for THIS job?
- Have they built something similar before?
- What's their proposed rate/bid?
- Any portfolio links to include?
-
Draft the proposal following this structure:
Opening Hook (1-2 sentences)
- Reference something SPECIFIC from the job posting
- Show you understand their problem, not just the job title
- Never start with "I am a..." or "Dear Hiring Manager"
Relevant Experience (2-3 sentences)
- Mention 1-2 directly relevant past projects
- Quantify results where possible (performance gains, users served, time saved)
- Match their tech stack and requirements explicitly
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.
