What it does
Project Brief is an agent skill from sd0xdev/sd0x-harness. Convert a technical spec into a PM/CTO-readable executive summary. Simplify technical details, focus on business value.
Its SKILL.md is about 720 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Writing & Content, covering Summarization. The repository describes itself as: The harness layer for Claude Code — a reference implementation of harness engineering with hook-enforced dual review, state-machine gates that survive context compaction, and… The licence is MIT.
When your agent uses it
- Tasks that involve Summarization
Example prompts
- “/project-brief”
Requirements
- Pre-approved tools (allowed-tools): Read, Grep, Glob, Write, Agent
Workflow steps
4 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit c9a2036. 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:
ReadGrepGlobWriteAgent
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).
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
Project Brief loads about 721 tokens when it runs. Until then it costs about 33 tokens; SKILL.md has 182 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.

Step 2: Extract Key Information
- Project overview: one sentence on what, why, and value
- Current state vs target comparison
- Solution evaluation (keep pros/cons comparison)
- Milestone timeline
- Risk summary
- Resource requirements
Step 3: Simplify Technical Details
- Remove code snippets
- Remove internal module names
- Remove technical implementation details
- Keep business logic descriptions
Step 4: Produce Executive Summary
