AgentDoctor: Skill for Cursor

.cursor/skills/agentdoctor-project-ownership/SKILL.md

agentdoctor-project-ownership is a skill for Cursor from pranee54/AgentDoctor. It costs 40 tokens per session (270 once invoked), scanned A, original, MIT.

A set of rules for deciding which files and directories belong to an AgentDoctor project. It handles nested repositories, private folders, fixtures, and symbolic links, which are filesystem references that point elsewhere.

In plain words
What is it for?
Use it when changing filesystem walkers, path resolution, project discovery, ownership checks, or cached project graphs.
Why use it?
It prevents project analysis from reading or indexing files that are outside the project's ownership boundary. It also requires caches and regression tests to reflect changes to those rules.

Skill for Cursor

Written for Cursor: installed under .cursor/.

This is pranee54/AgentDoctor's own configuration. It tells Cursor how to work on AgentDoctor itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything AgentDoctor configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

agentdoctor-project-ownership scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 29d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

AgentDoctor project ownership

Purpose

Ensure product intelligence only indexes project-owned source. Paths inside the scan root are not automatically owned.

Key module

src/project/ownership.ts — classifyRelativePathOwnership, decideDirectoryTraversal, assertProjectOwnedRepoPath, OWNERSHIP_BOUNDARY_VERSION (currently 4).

Non-owned by default

  • .private/, AgentDoctorOS/
  • nested repositories (.git under a subdirectory)
  • fixtures/, validation checkouts
  • symlink realpath that lands outside ownership

When changing ownership

  1. Bump OWNERSHIP_BOUNDARY_VERSION if classification semantics change
  2. Ensure Brain/Twin/Graph caches invalidate via stamp/hash
  3. Add hostile fixture regression (markers must not appear as VERIFIED)
  4. Update walker inventory if a new producer walks the filesystem

What NOT to do

Use lexical relativeHint alone after symlink resolution; treat control-plane .agentdoctor/ artifact I/O as source ownership (separate scope).

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

agentdoctor-project-ownership is a skill published in the GitHub repository pranee54/AgentDoctor (10 stars, last pushed 2d ago), licensed MIT. It adds 40 tokens to every session and 270 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-28.
