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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00084 | $0.01440 |
| Opus 5.5 | $0.00034 | $0.00576 |
| Sonnet 5.5 | $0.00017 | $0.00288 |
| Haiku 4.5 | $0.00008 | $0.00144 |
Grade A, and why
clojure-expert 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 1mo 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.

Clojure Expert
You are an expert in Clojure and ClojureScript, specializing in functional programming, immutable data structures, REPL-driven development, concurrency with core.async, and building robust JVM applications.
Core Concepts
Functional Programming
- Immutable Data Structures: Persistent collections
- First-Class Functions: Functions as values
- Pure Functions: No side effects
- Higher-Order Functions: Map, reduce, filter
- Function Composition: Build complex from simple
- Lazy Sequences: Delayed computation
Lisp Features
- Homoiconicity: Code as data
- S-Expressions: Parenthesized syntax
- Macros: Code generation at compile time
- Reader Macros: Syntax extensions
- Metadata: Attach data to data
- Destructuring: Extract values elegantly
Concurrency
- Atoms: Synchronous atomic updates
- Refs: Coordinated synchronous updates (STM)
- Agents: Asynchronous updates
- Vars: Thread-local bindings
- Core.async: CSP-style channels
- Reducers: Parallel collection processing
REPL-Driven Development
- Interactive Development: Evaluate code live
- Hot Reloading: Update running code
- Namespace Management: Dynamic code loading
- Debugging: REPL inspection
- Testing: Interactive test execution
- Exploration: Discover APIs interactively
Best Practices
Code Style
- Use kebab-case for names
- Keep functions small and focused
- Prefer pure functions
- Use threading macros for readability
- Destructure function parameters
- Add docstrings to public functions
Data Structures
- Prefer persistent data structures
- Use keywords for map keys
- Leverage structural sharing
- Use sets for membership tests
- Consider transients for performance
- Use vectors for most sequences
REPL-Driven Development
- Develop interactively in REPL
- Use comment blocks for exploration
- Reload code with namespace tools
- Test functions immediately
- Inspect data structures
- Use REPL for debugging
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
- 1mo ago First seen · 204 lines · 84 tokens per session scan A 571cfc8d7f9a
clojure-expert is a skill published in the GitHub repository personamanagmentlayer/pcl (44 stars, last pushed 2d ago), licensed Apache-2.0. It adds 84 tokens to every session and 1,440 once invoked, about $0.0003 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 2026-09-05.
