Pathrule vs CLAUDE.md, AGENTS.md and .cursorrules
Instruction files like CLAUDE.md, AGENTS.md and .cursorrules put team context in one file per tool. Pathrule keeps the same kind of knowledge but routes a path-scoped slice into every assistant at hook time. Here is how they line up, and when each makes sense.
Same goal, different shape
CLAUDE.md, AGENTS.md and .cursorrules all answer the same question: how do you give an AI coding assistant the context your team already knows? They answer it with a file the tool reads. That works on day one and is the right place to start.
Pathrule answers the same question with a path-scoped knowledge layer instead of a file. Memories, rules and skills attach to repository paths, and only the slice that matches the directory you are working in is delivered, at hook time, before the first tool call. The two approaches are not exclusive: Pathrule sits above your existing files.
Side by side
| Pathrule | CLAUDE.md | AGENTS.md | .cursorrules | |
|---|---|---|---|---|
| Scope | Path-scoped per directory | One file (nested files possible) | One file per directory, agent-read | Project and global rule files |
| Delivery | Injected at hook time, only the relevant slice | Whole file loaded each session | Read by the agent when present | Applied by Cursor |
| Token cost | Flat: only matching context | Grows with the file | Grows with the file | Grows with the rules |
| Works across tools | Claude Code, Cursor, Codex, Windsurf from one source | Claude Code | Codex and AGENTS.md-aware tools | Cursor |
| Enforcement | Priority plus strict rules can block a violation | Advisory text | Advisory text | Advisory rules |
| Governance | Reviewable graph, row-level security, audit | Git diffs, editable by anyone with push | Git diffs | Git diffs |
| Staleness | Self-audit surfaces stale entries as suggestions | Manual | Manual | Manual |
| Source code | Never stored; only typed memories, rules, skills | Lives in the repo | Lives in the repo | Lives in the repo |
Pathrule sits above these files; you do not have to delete them. Long read: AGENTS.md vs Pathrule.
When each one makes sense
A single instruction file. Best for a solo developer or a small, stable repo where one short file is easy to read and rarely changes. Start here; it is zero setup.
One file per tool. Fine while you use one assistant. The cost shows up when the team adds Cursor next to Claude Code and the same rules have to be copied into a second and third file.
Pathrule. Best when context is path-scoped, the team is more than one person, or you run more than one assistant. One reviewable source drives every tool, and each session only sees the rules that apply. See the context layer.
Frequently asked questions
Is Pathrule a replacement for CLAUDE.md?
No, it sits above it. Your CLAUDE.md keeps working; Pathrule adds a path-scoped layer so team rules do not have to live in one growing file, and so the same knowledge reaches Cursor and Codex too.
How does Pathrule compare to AGENTS.md?
AGENTS.md is a per-directory file the agent reads. Pathrule keeps the same kind of knowledge as memories, rules and skills attached to paths, delivers only the matching slice at hook time, and serves it to Claude Code, Cursor, Codex and Windsurf from one source.
How is Pathrule different from .cursorrules?
The .cursorrules file applies inside Cursor. Pathrule is tool-neutral: the same path-scoped rules drive Cursor, Claude Code and Codex, with priority and strict enforcement instead of advisory-only text.
Do I have to migrate off my existing files?
No. Pathrule layers on top. Many teams keep a short CLAUDE.md or AGENTS.md and move the path-specific, team-shared rules into Pathrule so each session only loads what applies.
Does the comparison mean files are bad?
No. A single file is the right starting point for one developer or a small repo. The trade-off appears at team scale and across multiple assistants, where one file per tool grows, drifts and gets ignored.
Does Pathrule store my source code?
No. Pathrule never reads or uploads source files. It stores only the typed memories, rules and skills your team writes. See the Security page.
