What it does
Explore is an agent skill from xwtro0tk1t-cloud/harness. Graph-driven project understanding using code-review-graph (CRG). Query architecture, modules, callers/callees, impact radius, hotspots, execution flows, and search nodes. Use when: (1) brainstorming and need to understand project structure, (2) writing plans and need impact analysis, (3) user says "understand this project", "how does this module work", "impact analysis", "/explore", (4) reviewing code changes and need blast radius. Requires .code-review-graph/graph.db — run /graph build first if missing.
Its SKILL.md is about 1.6k 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 Agent Workflows, covering Planning, Brainstorming and Code review. It works with SQLite. The repository describes itself as: Harness is an AI Agent development guardrail Meta-Skill that establishes four layers of defense for any project in one command: knowledge management, architecture constraints…
When your agent uses it
- Brainstorming and need to understand project structure
- Writing plans and need impact analysis
- User says understand this project
- How does this module work
Example prompts
- “understand this project”
- “how does this module work”
- “impact analysis”
- “/explore”
Requirements
- Python 3
What it can do on your machine
Read from SKILL.md and the folder at commit 3e8bb50. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
python
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
Explore loads about 1.6k tokens when it runs. Until then it costs about 130 tokens; SKILL.md has 325 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 325 words (~1,641 tokens).
“Query the project's code knowledge graph to understand architecture, trace call chains, and analyze impact. Powered by CRG's graph.db (SQLite) + CRG Python API.”

When should I use Explore?
Explore fits situations like: brainstorming and need to understand project structure; writing plans and need impact analysis; user says understand this project; how does this module work.
How do I install Explore in Claude Code?
Run `npx skills add xwtro0tk1t-cloud/harness --skill explore -a claude-code`. Or copy the skill folder (bundled-skills/explore in xwtro0tk1t-cloud/harness) into .claude/skills/explore in your project. Claude Code loads it when a task matches its description.
How do I install Explore in Codex?
Run `npx skills add xwtro0tk1t-cloud/harness --skill explore -a codex`. Or copy the skill folder (bundled-skills/explore in xwtro0tk1t-cloud/harness) into .agents/skills/explore in your project. Codex loads it when a task matches its description.
Can I use Explore 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 xwtro0tk1t-cloud/harness --skill explore -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/explore, .gemini/skills/explore, .github/skills/explore and .opencode/skills/explore in your project.
What does Explore need to run?
Going by SKILL.md and its folder, Explore needs the command-line tools its instructions call (python). Our summary lists: Python 3.
Does Explore 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 Explore 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 Explore use?
No licence was found for Explore or its repository. Without one, default copyright applies: ask the author before reusing or redistributing it.
How many tokens does Explore use?
About 1.6k tokens (SKILL.md is roughly 6.6k 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 Explore?
