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.

SkillSpector: 10 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00062 | $0.02257 |
| Opus 5 | $0.00031 | $0.01128 |
| Sonnet 5 | $0.00012 | $0.00451 |
| Haiku 4.5 | $0.00006 | $0.00226 |
Grade A, and why
zsh-path 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 8d 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.

Zsh PATH Management Skill
This skill provides comprehensive guidance for managing PATH environment variables in zsh, including troubleshooting missing commands, adding new tools, and organizing shell configuration.
When to Use This Skill
Use this skill when:
- Getting "command not found" errors for installed tools
- Adding new tools to PATH (bun, nvm, cargo, go, Python venv, etc.)
- Validating and auditing current PATH entries
- Organizing PATH configuration between .zshrc and .zshrc.local
- Troubleshooting shell startup issues related to PATH
- Setting up version managers (nvm, pyenv, rbenv)
Diagnostic Commands
Check Current PATH
# List all PATH entries
echo $PATH | tr ':' '\n'
# Check if specific command is in PATH
which bun 2>/dev/null || echo "bun not found in PATH"
# Find where a command is installed
command -v node
type -a python
Validate PATH Entries
# Check for broken/non-existent PATH entries
echo $PATH | tr ':' '\n' | while read p; do
[[ -d "$p" ]] || echo "MISSING: $p"
done
# Check for duplicate PATH entries
echo $PATH | tr ':' '\n' | sort | uniq -d
Common Tool PATH Configurations
Bun (JavaScript runtime)
# Add to .zshrc
export BUN_INSTALL="$HOME/.bun"
export PATH="$BUN_INSTALL/bin:$PATH"
Default location: ~/.bun/bin/bun
NVM (Node Version Manager)
# Add to .zshrc
export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"
Default location: ~/.nvm/
Note: NVM is a shell function, not a binary. It modifies PATH dynamically to point to the active Node version.
Python Virtual Environment
# Add to .zshrc for global tools venv
export PATH="$HOME/.venv/tools3/bin:$PATH"
# For pyenv
export PYENV_ROOT="$HOME/.pyenv"
export PATH="$PYENV_ROOT/bin:$PATH"
eval "$(pyenv init -)"
Rust/Cargo
# Add to .zshrc
export PATH="$HOME/.cargo/bin:$PATH"
Go
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.

zsh-path is a skill published in the GitHub repository julianobarbosa/claude-code-skills (10 stars, last pushed 16d ago), licensed MIT. It adds 62 tokens to every session and 2,257 once invoked, about $0.0003 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 2026-09-03.
