What it does
Estimation is an agent skill from Prorise-cool/Claude-Code-Multi-Agent. Estimation techniques including analogous, parametric, three-point, and expert judgment methods. Provides effort, cost, duration, and complexity estimates for projects, features, and tasks.
Its SKILL.md is about 3.4k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: Claude-Code-Multi-Agent驱动的新一代AI编程助手生态系统，基于Claude Code构建的智能代理协调工作空间，实现从需求到交付的全流程自动化开发.
Example prompts
- “/estimation”
Requirements
- Pre-approved tools (allowed-tools): Read, Glob, Grep, Task, Skill
Workflow steps
3 steps, taken from the step headings in SKILL.md.
- Prepare
- Estimate
- Communicate
What it can do on your machine
Read from SKILL.md and the folder at commit 0dc1305. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadGlobGrepTaskSkill
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown and yaml).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Estimation loads about 3.4k tokens when it runs. Until then it costs about 50 tokens; SKILL.md has 965 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 965 words (~3,401 tokens).

Estimation techniques including analogous, parametric, three-point, and expert judgment methods. Estimation is an agent skill from Prorise-cool/Claude-Code-Multi-Agent. Estimation techniques including analogous, parametric, three-point, and expert judgment methods.
How do I install Estimation in Claude Code?
Run `npx skills add Prorise-cool/Claude-Code-Multi-Agent --skill estimation -a claude-code`. Or copy the skill folder (.claude/skills/business-analysis/estimation in Prorise-cool/Claude-Code-Multi-Agent) into .claude/skills/estimation in your project. Claude Code loads it when a task matches its description.
How do I install Estimation in Codex?
Run `npx skills add Prorise-cool/Claude-Code-Multi-Agent --skill estimation -a codex`. Or copy the skill folder (.claude/skills/business-analysis/estimation in Prorise-cool/Claude-Code-Multi-Agent) into .agents/skills/estimation in your project. Codex loads it when a task matches its description.
Can I use Estimation in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add Prorise-cool/Claude-Code-Multi-Agent --skill estimation -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/estimation, .gemini/skills/estimation, .github/skills/estimation and .opencode/skills/estimation in your project.
What does Estimation need to run?
SKILL.md names no scripts, command-line tools or credentials: Estimation is instructions for the agent only. Its frontmatter pre-approves these tools: Read, Glob, Grep, Task, Skill.
Does Estimation access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Estimation safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Estimation use?
No licence was found for Estimation or its repository. Without one, default copyright applies: ask the author before reusing or redistributing it.
How many tokens does Estimation use?
About 3.4k tokens (SKILL.md is roughly 14k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Estimation?
Skills that share tags, products or a category with Estimation: Task Effort Estimator (Donchitos/Claude-Code-Game-Studios, 26k stars), Progressive Estimation (sickn33/agentic-awesome-skills, 47k stars), Mapping Mitre Attack Techniques (mukul975/Anthropic-Cybersecurity-Skills, 34k stars) and Estimating And Contingency (cbrock84/headcount, 2k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
