# Session Summary

**Date:** 2026-01-01 (Day 2 of ops-review skill)
**Focus Area:** Complete ops-review Phase 3 lenses and migrate worklog skill to markdown

# Accomplishments

- [x] Completed Phase 3 lenses: nix-hygiene, resilience, orchestration
- [x] All lenses validated via orch consensus (gemini, gpt, flash-or)
- [x] Closed ops-review epic (skills-9cu) - all 14 tasks complete
- [x] Migrated worklog skill from org-mode to markdown
- [x] Updated template, scripts, and SKILL.md for markdown format
- [x] Maintained backward compatibility with existing .org worklogs

# Key Decisions

## Decision 1: YAML frontmatter for markdown worklogs

- **Context:** Needed structured metadata like org-mode's `#+TITLE:` headers
- **Options considered:**
  1. YAML frontmatter (standard for static site generators, GitHub)
  2. TOML frontmatter (less common)
  3. Custom header format
- **Rationale:** YAML is widely supported, familiar syntax, works with tools like Jekyll/Hugo
- **Impact:** Worklogs now render properly on GitHub and in markdown viewers

## Decision 2: Backward compatibility in find-related-logs.sh

- **Context:** Existing worklogs use org-mode format
- **Rationale:** Detect file format and parse accordingly
- **Impact:** Old .org worklogs remain searchable alongside new .md files

# Problems & Solutions

| Problem | Solution | Learning |
|---------|----------|----------|
| Deployed skill still uses old format | Repo version updated; requires home-manager rebuild | Skill deployment is declarative via Nix |
| suggest-filename.sh from ~/.claude still outputs .org | Run repo version for testing; deployed version updates on rebuild | Test from repo, not deployed location |

# Technical Details

## Code Changes

- Total files modified: 4
- Key files changed:
  - `skills/worklog/SKILL.md` - Updated all org-mode references to markdown
  - `skills/worklog/scripts/suggest-filename.sh` - Changed .org to .md extension
  - `skills/worklog/scripts/find-related-logs.sh` - Added dual-format parsing
- New files created:
  - `skills/worklog/templates/worklog-template.md` - Markdown template with YAML frontmatter
- Files deleted:
  - `skills/worklog/templates/worklog-template.org` - Old org-mode template

## Commands Used

```bash
# Test suggest-filename outputs .md
skills/worklog/scripts/suggest-filename.sh

# Test find-related-logs parses both formats
skills/worklog/scripts/find-related-logs.sh "ops-review"
```

## Architecture Notes

- YAML frontmatter uses array syntax for keywords: `keywords: [a, b, c]`
- find-related-logs.sh detects format by checking for `^---$` (YAML frontmatter marker)
- Fallback to org-mode parsing if no frontmatter detected

# Process and Workflow

## What Worked Well

- Orch consensus for lens validation - each model catches different issues
- Incremental commits after each lens
- Testing scripts immediately after changes

## What Was Challenging

- Remembering that deployed skill differs from repo version
- YAML frontmatter quote handling in sed patterns

# Learning and Insights

## Technical Insights

- YAML frontmatter is more flexible than org-mode headers for tooling integration
- Git detects org→md as a rename when content similarity is high
- Shell script can detect file format and branch parsing logic

## Process Insights

- Test from repo directory, not deployed location during development
- Backward compatibility is low-cost and high-value

# Context for Future Work

## Open Questions

- Should we batch-convert existing .org worklogs to .md?
- Consider adding frontmatter validation

## Next Steps

- Rebuild home-manager to deploy updated skill
- Existing .org worklogs can remain as-is (backward compatible)

# Raw Notes

- This is the first worklog using the new markdown format
- Used as a test to verify the template works correctly
- YAML frontmatter renders nicely on GitHub
