A validated, editable AGENTS.md draft with live preview and the correct save location.
What AI Agent Instructions Generator returns
AI Agent Instructions Generator is designed to build and refine specification-aware Markdown instruction files for coding agents and reusable skills.
Input: file format, project or skill context, stack presets, commands, scope, constraints, triggers, and direct Markdown edits. Output: a correctly named agent instruction file in the selected format with live preview, placement guidance, and format-specific checks.
How AI Agent Instructions Generator works
Guided fields produce a deterministic draft that remains fully editable with toolbar actions, undo and redo, live preview, expanded view, and protected manual changes.
Resolve blocking format errors, then review triggers, commands, file paths, scope, guardrails, token size, and testable verification steps.
A useful situation for AI Agent Instructions Generator
Use it when you are standardizing how agents read a codebase, respect protected areas, make scoped edits, run checks, or activate a reusable workflow skill.
The workflow is intended for developers, AI-agent power users, documentation teams, and operations teams.
Limits and common errors
Static checks cannot prove that an instruction will improve every agent run, so generated files still need project-specific review and periodic maintenance.
A common mistake is using vague advice, pasting secret values, omitting required skill metadata, or configuring an auto-attached Cursor rule without globs.
Privacy and the next step
Instruction content is edited locally and no model call is made.
For a broader workflow, use the Markdown editor for unrelated documents and the token calculator when instruction context becomes large or costly.
If the result matters later, revisit current docs and skills after all Phase 2 tools are implemented so instructions match the latest behavior.
FAQ

Not silently. ToolFina warns before replacing Markdown that you edited manually.
Is AI Agent Instructions Generator free to use?
Yes. The public AI Agent Instructions Generator runs in the browser and does not require a sign-in for normal use.
How does AI Agent Instructions Generator handle my input?
Instruction content is edited locally and no model call is made.
What should I check before relying on the result?
Resolve blocking format errors, then review triggers, commands, file paths, scope, guardrails, token size, and testable verification steps. Also confirm that the input reflects the exact situation you are working on.
What is a common mistake with AI Agent Instructions Generator?
A common mistake is using vague advice, pasting secret values, omitting required skill metadata, or configuring an auto-attached Cursor rule without globs. Review the original material and the final output before publishing or sharing it.
