vercel-labs/bash-tool is a tool for AI agents that runs Bash commands and reads or writes files in a sandbox, with compatibility for the AI SDK. It gives agents a way to work with command-line operations and files. The catalogue entries are skills and instructions that extend agent use of this tool.
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 | $0.00010 | $0.00305 |
| Opus 5.5 | $0.00004 | $0.00122 |
| Sonnet 5.5 | $0.00002 | $0.00061 |
| Haiku 4.5 | $0.00001 | $0.00030 |
Grade A, and why
text 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.
What it actually says
Text Processing Skill
Process text files using standard bash tools (grep, sed, awk, wc).
Available Scripts
stats.sh
Get statistics about a text file (lines, words, characters).
bash /skills/text/scripts/stats.sh document.txt
search.sh
Search for patterns in text files.
bash /skills/text/scripts/search.sh <file> <pattern> [--count] [--context <lines>]
extract.sh
Extract specific lines or sections from a file.
bash /skills/text/scripts/extract.sh <file> --lines <start>-<end>
bash /skills/text/scripts/extract.sh <file> --between <start_pattern> <end_pattern>
wordfreq.sh
Count word frequencies in a text file.
bash /skills/text/scripts/wordfreq.sh document.txt [--top <n>]
Examples
# Get file statistics
bash /skills/text/scripts/stats.sh readme.txt
# Search with context
bash /skills/text/scripts/search.sh log.txt "ERROR" --context 2
# Extract lines 10-20
bash /skills/text/scripts/extract.sh file.txt --lines 10-20
# Top 10 most frequent words
bash /skills/text/scripts/wordfreq.sh article.txt --top 10
What ships with it
4 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.

text is a skill published in the GitHub repository vercel-labs/bash-tool (628 stars, last pushed 2mo ago), licensed MIT. It adds 10 tokens to every session and 305 once invoked, about $0.0000 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 2026-08-30.
