V7 · Repository context, maintained

Your code evolves.
Your AI context should too.

Find stale instructions. Prepare better CLAUDE.md and AGENTS.md files. Review the changes, then keep them aligned with your repository.

No account for public previews. Usage and repository-size limits apply. Private repositories require an authorized GitHub connection.

One convention has drifted.

The example instructions still reference the old API client.

CLAUDE.md
  Use src/lib/legacyClient.ts

  src/lib/api.ts is the shared client

A complete working loop

Better context starts with the code you actually have.

01

Inspect your actual code.

Find context gaps, stale instructions and configuration risks with a repository scan.

02

Review a better setup.

Prepare grounded context files. Inspect the changes and preserve your team’s intentional guidance.

03

Keep the context current.

Rescan after changes. Add GitHub checks and fleet monitoring when you need ongoing upkeep.

One workflow. The right tools.

Explore all products

Repository context

Inspect repository context, identify gaps, and prepare CLAUDE.md and AGENTS.md files grounded in your actual stack and conventions.

Fleet maintenance

Review repository health, drift alerts and GitHub checks across your fleet, then inspect proposed context updates before they land.

Agent design

Design agent responsibilities, routing and handoffs, then export implementation scaffolds for the frameworks supported by Agent Architect.

Security review

Inspect prompts, MCP manifests, agent architectures and vendor answers with focused security tools and explicit review boundaries.

A prompt toolkit, too.

Craft, rate and edit instructions for your own workflow. Start with a template, then test it against real examples.

Trust starts with clear boundaries.

Understand what is processed, what is retained and what an automated check can tell you.

Read about data handling

Public preview ≠ saved analysis

A public preview produces a limited summary. Signed-in analysis retains files and a profile to support your workflow.

Access should fit the task

Connect only the repositories you need. Inspect integration permissions and proposed changes.

A score is a starting point

Review evidence, run your tests and verify the result. Automated checks do not certify a system.

What does PrompterJack do?

PrompterJack helps developers inspect, improve and maintain the instructions and setup used by AI coding tools. Repository analysis is the starting point; prompt, agent-design and security tools support the wider workflow.

Can I try it without an account?

Yes. Paste a public GitHub repository above for a limited preview. Saved profiles and authorized private-repository analysis require sign-in and an eligible plan.

Does it replace Claude Code, Cursor or Copilot?

No. It helps prepare and maintain context for your existing tools. Verify which instruction files and configuration your chosen tool supports.

Will generated files make every AI response correct?

No. Context can improve the information a tool works with, but generated changes still need review and tests. Health and quality scores are review aids, not guarantees.
