What is find-plugin-file?

A file-search utility for locating scripts, skills, and other resources inside the Claude Code plugin cache, where installed plugin files are stored.

Use it to find a file by name or path pattern, list installed plugins, or locate resources for slash commands and agents.

It avoids relying on a fixed cache path or plugin version when the needed file has moved. It can also restrict searches to a particular plugin.

Install

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.

Any agent

npx skills add closedloop-ai/claude-plugins --skill find-plugin-file

Clone the repo

git clone --depth 1 https://github.com/closedloop-ai/claude-plugins

Made for: Claude Code.

Or install code, the plugin that ships this one along with the rest of its 13 skills, 6 commands, 23 agents, 7 hooks.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00070	$0.00767
Opus 5.5	$0.00028	$0.00307
Sonnet 5.5	$0.00014	$0.00153
Haiku 4.5	$0.00007	$0.00077

Security

Grade B, and why

find-plugin-file scanned grade B with 1 finding 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.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/find_plugin_file.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Reads agent configuration directoriesmediumAgent snooping

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

This skill provides a utility to dynamically locate files within the Claude Code plugins cache directory. Instead of hardcoding plugin-cache paths, use this skill to find files in `~/.claude/plugins/cache/closedloop-ai/`

Find Plugin File

Overview

This skill provides a utility to dynamically locate files within the Claude Code plugins cache directory. Instead of hardcoding plugin-cache paths, use this skill to find files in ~/.claude/plugins/cache/closedloop-ai/ with automatic latest-version resolution.

Quick Start

To find a file in the plugins cache, run the find_plugin_file.py script:

python3 scripts/find_plugin_file.py <file_pattern>

Usage Examples

Find by filename

# Find parse_args.py in any plugin (returns first match)
python3 scripts/find_plugin_file.py parse_args.py

# Find all SKILL.md files across all plugins
python3 scripts/find_plugin_file.py SKILL.md --all

Find by path pattern

# Find a specific file using path pattern
python3 scripts/find_plugin_file.py plan/parse_args.py

# Find tools in a specific subdirectory
python3 scripts/find_plugin_file.py tools/python/plan/parse_args.py

Restrict to specific plugin

# Search only in code plugin
python3 scripts/find_plugin_file.py parse_args.py --plugin code

List available plugins

python3 scripts/find_plugin_file.py --list-plugins

Integration with Slash Commands

To use in a slash command that needs to reference plugin tools, use a two-step approach:

# Step 1: Locate the find_plugin_file.py script (handles multiple plugin versions)
FIND_SCRIPT=`ls ~/.claude/plugins/cache/closedloop-ai/code/*/skills/find-plugin-file/scripts/find_plugin_file.py 2>/dev/null | sort -V | tail -1`

# Step 2: Use the script to find the target file, then derive TOOLS_PATH
TARGET_FILE=`python3 "$FIND_SCRIPT" plan/parse_args.py`
TOOLS_PATH=`dirname \`dirname "$TARGET_FILE"\``

# Step 3: Run with correct PYTHONPATH
PYTHONPATH="$TOOLS_PATH:$PYTHONPATH" python3 "$TARGET_FILE" --help

Important:

Use backticks (`) instead of $() for command substitution — Claude Code's Bash tool escapes $() syntax.
The glob pattern code/*/skills/... can match multiple version directories. Always use ls ... | sort -V | tail -1 to select the latest version.

What ships with it

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.

find-plugin-file is a skill published in the GitHub repository closedloop-ai/claude-plugins (123 stars, last pushed today), licensed Apache-2.0. It adds 70 tokens to every session and 767 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-07.
