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.

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 | $0.00060 | $0.02106 |
| Opus 5 | $0.00030 | $0.01053 |
| Sonnet 5 | $0.00012 | $0.00421 |
| Haiku 4.5 | $0.00006 | $0.00211 |
Grade C, and why
bash-lint scanned grade C 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 5d 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.
Recursive force deletehighDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

Bash Linting
Shellcheck and shfmt integration for bash script quality assurance.
Shellcheck
Installation
# Debian/Ubuntu
apt install shellcheck
# macOS
brew install shellcheck
# From source
cabal update && cabal install ShellCheck
Basic Usage
# Check single file
shellcheck script.sh
# Check multiple files
shellcheck *.sh
# With specific shell dialect
shellcheck --shell=bash script.sh
shellcheck --shell=sh script.sh
# Exclude specific rules
shellcheck --exclude=SC2086 script.sh
shellcheck --exclude=SC2086,SC2046 script.sh
# Output formats
shellcheck --format=gcc script.sh # GCC-style
shellcheck --format=json script.sh # JSON for tooling
shellcheck --format=diff script.sh # Unified diff
Common Shellcheck Codes
| Code | Issue | Fix |
|---|---|---|
| SC2086 | Double quote to prevent globbing/splitting | "$var" |
| SC2046 | Quote command substitution | "$(cmd)" |
| SC2006 | Use $() instead of backticks |
$(cmd) |
| SC2034 | Variable appears unused | Remove or export |
| SC2155 | Declare and assign separately | Split local var; var=$(...) |
| SC2164 | Use cd ... || exit |
Handle cd failure |
| SC2181 | Check exit status directly | if cmd; then |
| SC2129 | Consider grouping writes | Use { } > file |
| SC1090 | Can't follow sourced file | Use # shellcheck source=path |
| SC2154 | Variable referenced but not assigned | Initialize or declare |
Shellcheck Directives
# Disable for next line
# shellcheck disable=SC2086
echo $unquoted_var
# Disable for entire file (at top)
# shellcheck disable=SC2086,SC2046
# Specify source file for sourcing
# shellcheck source=./lib/functions.sh
source "$SCRIPT_DIR/lib/functions.sh"
# Specify shell dialect
# shellcheck shell=bash
# Disable for block (not supported - use per-line)
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.

bash-lint is a skill published in the GitHub repository Jamie-BitFlight/claude_skills (66 stars, last pushed yesterday), licensed MIT. It adds 60 tokens to every session and 2,106 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it C with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
