Practical overview
When it fits
Use Repository Harness when coding agents need clearer repository context and you want a maintained, repository-native protocol rather than task tracking or agent orchestration. It is also relevant when updating that protocol must account for local changes.
Who it is for
- Software teams using Claude Code, Codex, Cursor or other coding agents in existing repositories.
- Repository maintainers who want durable project context and a safer way to update shared agent guidance.
Documented uses
- Direct a coding agent to authoritative project documents and repository navigation.
- Keep product intent, decisions and implementation evidence grounded in the repository.
- Preview and maintain the installed protocol while preserving local edits.
- Explicitly invoke optional workflows for repository onboarding, invariant encoding or evidence-backed Harness improvements.
Requirements & limits
The project is identified as open source under the MIT license. The documented interface is a CLI.
- The repository remains the system of record; consumer repositories own their task workflow and planning.
- Harness skills are explicit-only and do not activate just because the tool is installed.
- The default core does not provide application runtimes, credentials, fixtures, logs or interface automation.
- The updater stages overlapping local and upstream edits for human resolution rather than silently choosing a semantic result.
Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
Install Repository Harness in a project
Add the default repository protocol and agent context to a target repository using the documented Unix-like bootstrap.
Before you start
- A target software repository.
- A shell environment with the documented curl and bash commands.
Steps
From the target repository, run the documented install command with the --yes option.
Use --merge to preserve existing files and add only missing Harness paths, or use --dry-run to preview.
Review the installed AGENTS.md entrypoint and docs/README.md repository map.
Expected outcome
The declared Harness core is installed in the repository, including its compact agent entrypoint and navigation context.
Guide limitations
- Use --override only when replacing existing files is intentional.
- Installation does not provide application architecture, product policy, validation commands, credentials, a database, schemas, orchestration or background processes.
- Harness skills require explicit user invocation and do not run during installation.
Preview and apply a Harness update
Use the installed maintenance binary to inspect an update and apply it when ready.
Before you start
- A repository with Harness installed and the documented scripts/bin/harness binary.
Steps
Run scripts/bin/harness status and scripts/bin/harness doctor.
Preview the update with scripts/bin/harness update --dry-run.
Apply it with scripts/bin/harness update.
Expected outcome
The updater uses a three-way merge, backs up changed files and activates the result transactionally.
Guide limitations
- Overlapping local and upstream edits are staged without changing managed files or the executable; a human must resolve the semantic choice.
- The documented continuation process includes a further dry run before continuing after conflict resolution.
