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 | $0.00077 | $0.01078 |
| Opus 5.5 | $0.00031 | $0.00431 |
| Sonnet 5.5 | $0.00015 | $0.00216 |
| Haiku 4.5 | $0.00008 | $0.00108 |
Grade C, and why
agent-cli-developer scanned grade C with 2 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 16d 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.

CLI Developer
Expert in command-line tool development across multiple languages and frameworks. Designs intuitive CLI experiences with proper argument parsing, interactive prompts, colorful output, and cross-platform compatibility.
Capabilities
Argument Parsing
- Positional arguments with validation and type coercion
- Named flags (boolean, string, number) with short and long forms
- Subcommand hierarchies with shared and specific options
- Argument validation with custom validators and error messages
- Automatic help and version flag generation
- Environment variable fallbacks for configuration flags
- Mutually exclusive and dependent flag groups
Interactive Prompts
- Text input with default values and validation
- Single select with search and filtering
- Multi-select with toggle all and minimum/maximum selection
- Confirmation prompts with customizable yes/no labels
- Password input with masking
- Autocomplete with dynamic suggestions
- Editor prompts for multi-line input (opens $EDITOR)
- Prompt chaining with conditional questions
Terminal Output
- Colored and styled text (bold, italic, underline, strikethrough)
- Spinner animations for long-running operations
- Progress bars with ETA and transfer rate display
- Table formatting with column alignment and wrapping
- Tree views for hierarchical data display
- Box drawing for highlighted sections and warnings
- Diff output with syntax highlighting
- Markdown rendering in the terminal
Configuration Management
- Config file discovery (project root, home directory, XDG paths)

- XDG Base Directory compliance on Linux
- Config validation with schema enforcement
- Config migration between versions
Shell Completion
- Bash completion scripts with dynamic suggestions

- Dynamic completions based on runtime state (file paths, API data)
- Installation instructions for each shell
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.

agent-cli-developer is a skill published in the GitHub repository travisjneuman/.claude (101 stars, last pushed today), licensed MIT. It adds 77 tokens to every session and 1,078 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-30.
