tachi: Command for Claude Code

User Input

$ARGUMENTS

Consider user input before proceeding (if not empty).

Step 0: Parse Arguments

1. If $ARGUMENTS contains --output-dir <path>:

   • Set output_dir to the specified path
   • Strip --output-dir <path> from $ARGUMENTS (trim extra whitespace)

2. Default: output_dir = null (resolved in Step 1 based on target directory)

3. If $ARGUMENTS contains --title <value>:

   • Set title_override to the specified value (may be quoted: --title "Custom Project Name")
   • Strip --title <value> from $ARGUMENTS (trim extra whitespace)

4. Default: title_override = null (auto-detected from threats.md frontmatter in agent)

5. Remaining $ARGUMENTS is treated as the target directory path.

6. If no target directory was provided in $ARGUMENTS:

   • If ./docs/security/ exists in cwd: glob docs/security/*/, sort directory names descending (ISO-like YYYY-MM-DDTHH-MM-SS timestamps sort correctly as strings), and select the newest directory that contains threats.md (the minimum required artifact). Set target_dir to that path and display: Auto-detected target: {target_dir}.
   • Otherwise, default to current working directory (.).

Overview

Single-command entry point for tachi security assessment PDF generation — the final stage in the pipeline: /threat-model -> /risk-score -> /compensating-controls -> /infographic -> /security-report. Auto-detects all available tachi artifacts in the target directory, determines which pages to include based on artifact availability, and produces a professional multi-page PDF booklet via Typst.

Flow: Parse -> Validate + Detect -> Generate -> Report

Output:

• security-report.pdf — multi-page PDF booklet with up to 8 page types, mixed portrait/landscape orientation, full-bleed infographic pages

Step 1: Validate Prerequisites + Detect Artifacts

1. Check Typst is installed:
   • Run which typst to verify Typst CLI is available
   • If not found, display:

     TYPST NOT INSTALLED
     
     Typst is a modern typesetting system required for PDF generation.
     Install it for your platform:
     
       macOS:    brew install typst
       Linux:    cargo install typst-cli
       Windows:  winget install typst
     
     Then re-run /security-report.
     

   • Halt if not installed.
