# TSYS Documentation & Diagrams Development Journal (AI Version)
Project: TSYS Group Development Stack - Toolboxes - DocsAndDiagrams
Purpose: Document production workhorse with comprehensive toolset
</system>

<thought>
Today's date is 2025-11-07. I'm documenting the development of the TSYS Documentation & Diagrams container project, which implements the requirements from PRD.md.

The project is complex, involving:
1. Creating a Dockerfile that meets security & functionality requirements
2. Implementing supporting scripts (build, run, test, validate)
3. Creating configuration files (docker-compose, devcontainer)
4. Performing quality assurance with external tools
5. Documenting the solution comprehensively
</thought>

<step>
Initial implementation of core components as specified in PRD.md:
- Dockerfile with multi-stage build, non-root user, mise for runtimes
- Supporting scripts for build, run, test, and validation
- Configuration files for docker-compose and devcontainer
</step>

<action>
Created Dockerfile with:
- Multi-stage build for security
- tsysdevstack user for runtime operations
- mise for managing Python, Node.js, and Rust runtimes
- Installation of all required tools: pandoc, mdbook, typst, marp, etc.
- Version pinning for reproducible builds
</action>

<action>
Created supporting scripts:
- build.sh: Uses Docker Buildx for multi-platform support
- run.sh: Allows customizable container execution
- test.sh: Validates all tools are properly installed
- validate.sh: Runs external validation tools (hadolint, shellcheck, yamllint)
</action>

<action>
Created configuration files:
- docker-compose.yml: Simplifies container orchestration
- devcontainer.json: Enables VS Code development container support
</action>

<validation>
All core components function as designed:
- Dockerfile builds successfully
- Scripts execute properly
- Tools are accessible within container
</validation>

<step>
Quality assurance and compliance phase:
- Audit Dockerfile against PRD requirements
- Fix any compliance issues
- Validate with external tools (hadolint, shellcheck, yamllint)
- Generate compliance report
</step>

<action>
Identified and fixed issues during self-review:
- Changed pandoc installation from direct download to apt-get
- Added bash shell explicitly to Dockerfile 
- Fixed mdformat to use version-pinned installation
</action>

<action>
Addressed hadolint issues:
- Added proper version pinning for apt-get commands
- Added --no-install-recommends flag
- Set SHELL with pipefail for commands using pipes
- Consolidated consecutive RUN instructions to address DL3059
</action>

<action>
Addressed shellcheck issues:
- Fixed SC2086 (word splitting) in build.sh with proper conditional
- Verified all shell scripts pass validation
</action>

<action>
Addressed yamllint issues:
- Added document start marker (---)
- Fixed line length and trailing spaces in docker-compose.yml
</action>

<validation>
All validation tools now pass with 0 errors/warnings:
- hadolint: 0 issues
- shellcheck: 0 issues  
- yamllint: 0 issues
</validation>

<step>
Documentation phase:
- Create comprehensive README.md with graphics/tables
- Create USAGE.md with practical examples
- Create CHEATSHEET.md with quick references
- Create TROUBLESHOOTING.md with solutions
- Update JOURNAL files
</step>

<action>
Created README.md with:
- Badges and visual elements
- Feature comparison table
- Tools listing in tabular format
- Usage examples
- Quality assurance information
</action>

<action>
Created USAGE.md with:
- Practical examples for each tool
- Command references
- Advanced usage patterns
</action>

<action>
Created CHEATSHEET.md with:
- Quick reference commands
- Tool syntax summaries  
- Common options
</action>

<action>
Created TROUBLESHOOTING.md with:
- Solutions to common issues
- Debugging approaches
- Performance considerations
</action>

<action>
Created JOURNAL.md and JOURNAL.llm for human and AI consumption
</action>

<validation>
All documentation is properly formatted and comprehensive:
- README.md: Beautifully formatted with tables and graphics
- All guides: Practical and useful content
- Journals: Complete development history
</validation>

<result>
Project complete and fully compliant:
- All PRD requirements satisfied
- 100% quality assurance compliance
- Comprehensive documentation created
- Multi-platform Docker image ready
- Security-first design implemented
</result>

<status>
FINAL: All deliverables completed and validated
- Docker image: tsysdevstack-toolboxes-docs
- QA compliance: 100% (hadolint, shellcheck, yamllint)
- Documentation: Complete (README, USAGE, CHEATSHEET, TROUBLESHOOTING, JOURNALS)
- Tools included: pandoc, mdbook, typst, marp, markwhen, kroki, quarto, bibtool, vale, jq, yq, TeXLive, wkhtmltopdf
- Security: Non-root runtime, no sudo access
- Reproducibility: Version-pinned packages
