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 | $0.00047 | $0.00683 |
| Opus 5 | $0.00023 | $0.00342 |
| Sonnet 5 | $0.00009 | $0.00137 |
| Haiku 4.5 | $0.00005 | $0.00068 |
Grade A, and why
file-search 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 10d 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 — 102 lines — stays where its author put it; the contents beside it link to each section on GitHub.
File Search
Modern file and content search.
fd - Find Files
# Find by name
fd config # Files containing "config"
fd -e py # Python files
# By type
fd -t f config # Files only
fd -t d src # Directories only
# Exclude
fd -E node_modules # Exclude directory
fd -E "*.min.js" # Exclude pattern
# Execute command
fd -e py -x wc -l # Line count per file
rg - Search Content
# Simple search
rg "TODO" # Find TODO
rg -i "error" # Case-insensitive
# By file type
rg -t py "import" # Python files only
rg -t js -t ts "async" # JS and TS
# Context
rg -C 3 "function" # 3 lines before/after
# Output modes
rg -l "TODO" # File names only
rg -c "TODO" # Count per file
fzf - Interactive Selection
# Find and select
fd | fzf
# With preview
fd | fzf --preview 'bat --color=always {}'
# Multi-select
fd -e ts | fzf -m | xargs code
Combined Patterns
# Find files, search content
fd -e py -x rg "async def" {}
# Search, select, open
rg -l "pattern" | fzf --preview 'rg -C 3 "pattern" {}' | xargs vim
Quick Reference
| Task | Command |
|---|---|
| Find TS files | fd -e ts |
| Find in src | fd -e ts src/ |
| Search pattern | rg "pattern" |
| Search in type | rg -t py "import" |
| Files with match | rg -l "pattern" |
| Count matches | rg -c "pattern" |
| Interactive | fd | fzf |
| With preview | fd | fzf --preview 'bat {}' |
Performance Tips
| Tip | Why |
|---|---|
Both respect .gitignore |
Auto-skip node_modules, dist |
Use -t over -g |
Type flags are faster |
| Narrow the path | rg pattern src/ faster |
Use -F for literals |
Avoids regex overhead |

What ships with it
3 files 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.
- 10d ago First seen · 102 lines · 47 tokens per session scan A 43cddbf3b4a5
file-search is a skill published in the GitHub repository 0xDarkMatter/claude-mods (34 stars, last pushed 17d ago), licensed MIT. It adds 47 tokens to every session and 683 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 2026-08-30.
