Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00030 | $0.01027 |
| Opus 5 | $0.00015 | $0.00513 |
| Sonnet 5 | $0.00006 | $0.00205 |
| Haiku 4.5 | $0.00003 | $0.00103 |
Grade A, and why
q-scan-project 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 5d 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.
How it starts
The opening of the file, as written. The whole thing — 118 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/q-scan-project
You are scanning the user's project to understand its structure and document what you find. Your job is to explore the codebase and write a useful summary that other skills can reference.
Process
-
Check for existing project.md. If
.quiddity/project.mdalready exists, read it and ask the user if they want to update it or start fresh. -
Scan the project. Look for the following and note what you find:
Key documentation files
- README, README.md
- ARCHITECTURE.md, DESIGN.md
- CONTRIBUTING.md
- CHANGELOG.md
- ROADMAP.md
- CLAUDE.md, .cursorrules, or other agent configuration
- Any docs/ or documentation/ directory
Project configuration
- package.json, Cargo.toml, pyproject.toml, go.mod, Gemfile, etc.
- What language(s) and framework(s) does the project use?
- What package manager? (npm, pnpm, yarn, bun, cargo, pip, etc.)
- Monorepo structure? (workspaces, lerna, turborepo, etc.)
Source structure
- Where does source code live? (src/, lib/, app/, etc.)
- Entry points (main files, index files, etc.)
- Test directory structure (tests/, tests/, spec/, etc.)
CI/CD and configuration
- .github/workflows/, .circleci/, Jenkinsfile, etc.
- Docker files (Dockerfile, docker-compose.yml)
- Deployment configuration (vercel.json, fly.toml, etc.)
Existing conventions
- .editorconfig, .prettierrc, .eslintrc, etc.
- PR templates (.github/pull_request_template.md)
- Issue templates (.github/ISSUE_TEMPLATE/)
- CODEOWNERS
Plans and specs
- Any planning documents, RFCs, ADRs (architecture decision records)
- Spec files or design documents
- TODO files
-
Ask clarifying questions. If anything is ambiguous, ask the user:
- Is there anything important about the project structure not captured above?
- Are there any conventions or patterns that aren't obvious from the files?
-
Set up architecture reference. Other skills (like
/next-task) read.quiddity/architecture.mdto understand the technical architecture before implementing changes. This document may describe things not yet built — it's a reference for where the project is going, not just where it is now.
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.

q-scan-project is a skill published in the GitHub repository jlong/quiddity (5 stars, last pushed 6mo ago), licensed MIT. It adds 30 tokens to every session and 1,027 once invoked, about $0.0002 per session on Opus 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 2026-08-31.
