Claude Code Agent Harness Setup is a skill published by agensi that configures a Claude Code agent with a set of pre-commit automations and guardrails scoped to a specific project. The skill bundles secret detection using gitleaks to scan for API keys, tokens, and private keys before commits reach a remote repository. It also adds credential safety monitoring to prevent authentication headers or OAuth tokens from appearing in console logs or stdout. Destructive Git commands such as reset —hard and push —force require forced confirmation before execution, reducing the risk of accidental data loss or overwriting a colleague’s work. A four-rule content quality gate is also included, checking published assets against standards covering pricing, metadata, and tone. The skill implements programmatic enforcement rather than relying on prompting an agent to behave carefully, meaning the checks run locally and are mandatory rather than optional. No tools are exposed directly to the agent runtime; the capability operates as a harness that shapes how the Claude Code agent interacts with Git and the local filesystem. It has no listed license, no package registry entry, and no repository URL in the available facts. This skill is appropriate when a team wants consistent, enforceable safety checks on a Claude Code agent operating within a single project context.

Use cases

Configure a Claude Code agent to run gitleaks secret scanning before every commit

Prevent OAuth tokens or authentication headers from being written to stdout during agent-driven development

Require confirmation before an agent executes destructive Git commands like force-push or hard reset

Enforce a four-rule content quality gate on published assets for pricing, metadata, and tone

Set up project-specific agent guardrails without relying on prompt-level instructions

When to use it

When a Claude Code agent is being used for automated commits in a project that handles secrets or credentials

When a team wants mandatory pre-commit checks rather than optional prompting

When destructive Git operations need an explicit confirmation step enforced at the tooling level

When published assets must consistently pass quality checks on metadata and tone

When not to use it

When the target agent runtime is not Claude Code, as this skill is specific to that agent

When a repository-wide or CI/CD-level enforcement strategy is needed rather than a local pre-commit approach

When a license, package registry, or versioned distribution is required, as none are provided in the facts
