# Key Decisions
|
||||
|
||||
## Decision 1: Test extraction approach using awk instead of sed
|
||||
|
||||
- **Context:** Need to extract functions from update-agent-context.sh for isolated testing
|
||||
- **Options considered:**
|
||||
1. `sed -n '/^function()/,/^}$/p'` - Original approach
|
||||
2. `awk '/^function\(\)/,/^}$/ {print; if (/^}$/) exit}'` - More precise
|
||||
3. Source entire script with mocked dependencies
|
||||
- **Rationale:** awk with explicit exit on closing brace is more reliable for multi-function scripts
|
||||
- **Impact:** Clean function extraction without pulling in adjacent functions
|
||||
|
||||
## Decision 2: Fix the bug rather than document as expected behavior
|
||||
|
||||
- **Context:** Found that Recent Changes section was silently skipped when preceded by Active Technologies
|
||||
- **Rationale:** This was clearly unintended behavior - the code was supposed to update both sections
|
||||
- **Impact:** Agent context files now correctly receive change entries regardless of section ordering
|
||||
|
||||
# Problems & Solutions
|
||||
|
||||
| Problem | Solution | Learning |
|
||||
|---------|----------|----------|
|
||||
| eval/sed extraction didn't work correctly for update_existing_agent_file | Used awk with explicit exit on `^}$` pattern | awk is more precise for function boundary detection |
|
||||
| Tests failing: change entries not added to existing Recent Changes | Traced through code, found `## Recent Changes` caught by generic "close tech section on any ##" logic | State machine section handlers must check specific headers before generic patterns |
|
||||
| Idempotency test counting wrong pattern | Pattern "Python + Django" appeared in both tech and change sections | Use anchored regex `^- pattern$` for specific line matching |
|
||||
|
||||
# Technical Details
|
||||
|
||||
## Code Changes
|
||||
|
||||
- Total files modified: 2
|
||||
- Key files changed:
|
||||
- `.specify/scripts/bash/update-agent-context.sh` - Fixed section ordering in while loop
|
||||
- `.specify/scripts/bash/tests/test-agent-update.sh` - New test file (33 tests)
|
||||
|
||||
## The Bug
|
||||
|
||||
The `update_existing_agent_file` function processes files line-by-line with a state machine. When in the Active Technologies section (`in_tech_section=true`), encountering any `##` header would:
|
||||
|
||||
1. Add pending tech entries
|
||||
2. Echo the header line
|
||||
3. Set `in_tech_section=false`
|
||||
4. **Continue to next iteration** ← Bug here!
|
||||
|
||||
This meant `## Recent Changes` was echoed but the change entry addition code (which checks `if [[ "$line" == "## Recent Changes" ]]`) was never reached.
|
||||
|
||||
**Fix:** Check for `## Recent Changes` BEFORE the generic "any ## closes tech section" logic:
|
||||
|
||||
```bash
|
||||
# Handle Recent Changes section FIRST (before generic ## handling)
|
||||
if [[ "$line" == "## Recent Changes" ]]; then
|
||||
# Close tech section if we were in it
|
||||
if [[ $in_tech_section == true ]]; then
|
||||
if [[ $tech_entries_added == false ]] && [[ ${#new_tech_entries[@]} -gt 0 ]]; then
|
||||
printf '%s\n' "${new_tech_entries[@]}" >> "$temp_file"
|
||||
tech_entries_added=true
|
||||
fi
|
||||
in_tech_section=false
|
||||
fi
|
||||
echo "$line" >> "$temp_file"
|
||||
# Add new change entry right after the heading
|
||||
if [[ -n "$new_change_entry" ]]; then
|
||||
echo "$new_change_entry" >> "$temp_file"
|
||||
fi
|
||||
...
|
||||
fi
|
||||
```
|
||||
|
||||
## Test Categories
|
||||
|
||||
1. **Basic Functionality** (4 tests) - Tech/change entries added, existing content preserved
|
||||
2. **Missing Sections** (6 tests) - Creates sections when absent
|
||||
3. **Timestamp Updates** (2 tests) - Updates `**Last updated**:` dates
|
||||
4. **Idempotency** (1 test) - No duplicates when re-running
|
||||
5. **Change Entry Limits** (5 tests) - Max 2 existing changes kept
|
||||
6. **Database Entries** (3 tests) - DB-only additions work
|
||||
7. **Tech Entry Placement** (3 tests) - Entries at correct position
|
||||
8. **Edge Cases** (5 tests) - Empty, NEEDS CLARIFICATION, EOF handling
|
||||
9. **format_technology_stack** (4 tests) - Helper function unit tests
|
||||
|
||||
## Commands Used
|
||||
|
||||
```bash
|
||||
# Run the tests
|
||||
bash .specify/scripts/bash/tests/test-agent-update.sh
|
||||
|
||||
# Debug function extraction
|
||||
eval "$(awk '/^update_existing_agent_file\(\)/,/^}$/ {print; if (/^}$/) exit}' script.sh)"
|
||||
|
||||
# Trace execution
|
||||
bash -x -c '...'
|
||||
```
|
||||
|
||||
# Process and Workflow
|
||||
|
||||
## What Worked Well
|
||||
|
||||
- Test-first debugging: Writing tests exposed the bug immediately
|
||||
- Incremental tracing: Adding debug output to narrow down the issue
|
||||
- Hypothesis testing: Created minimal test cases to verify the bug cause
|
||||
|
||||
## What Was Challenging
|
||||
|
||||
- Function extraction: eval/sed patterns are finicky with nested braces
|
||||
- Understanding state machine flow: Had to trace through manually to find where `continue` was short-circuiting
|
||||
|
||||
# Learning and Insights
|
||||
|
||||
## Technical Insights
|
||||
|
||||
- Bash state machines need careful ordering: specific cases before generic patterns
|
||||
- `continue` in while loops can silently skip subsequent handlers
|
||||
- Test fixtures with `setup_test_file()` using heredocs are clean for bash testing
|
||||
- grep patterns for line counting need anchoring to avoid false positives
|
||||
|
||||
## Process Insights
|
||||
|
||||
- When tests fail unexpectedly, the code might be buggy (not just the tests)
|
||||
- Adding debug output (`echo "DEBUG: ..." >&2`) is fast way to trace bash
|
||||
|
||||
# Context for Future Work
|
||||
|
||||
## Open Questions
|
||||
|
||||
- Should we add more tests for create_new_agent_file function?
|
||||
- Consider shellcheck/shfmt for the test files?
|
||||
|
||||
## Next Steps
|
||||
|
||||
- skills-s92: Add tests for deploy-skill.sh (continues testing theme)
|
||||
- skills-7bu: Add atomic file operations (related to file update code)
|
||||
- Rebuild home-manager to deploy updated script
|
||||

- skills-x33: Branch name tests (27 tests, completed in prior session)

# Raw Notes
|
||||
|
||||
- The deployed worklog skill still uses .org format; repo has .md
|
||||
- Network issue prevented bd sync (192.168.1.108:3000 unreachable)
|
||||
- Total test count across both test files: 60 tests (27 branch + 33 agent)
