Maintenance Guidelines + +**When to Update a Subagent:** +- Codebase changes affect the subagent's domain +- New features or capabilities are added +- Bugs or inaccuracies are discovered +- User feedback indicates gaps in knowledge +- Related documentation is updated + +**How to Update:** +- Review the entire file for consistency +- Update affected sections while maintaining structure +- Test examples and code snippets +- Verify cross-references still work +- Check for formatting consistency + +**When to Create a New Subagent:** +- A new domain of expertise is needed +- An existing subagent is becoming too broad +- Multiple distinct areas of knowledge are mixed +- Separation would improve clarity and maintainability + +### 6. File Naming Conventions + +Subagent files should: +- Use lowercase letters +- Use hyphens for word separation (not underscores or spaces) +- Be descriptive but concise +- Have `.md` extension +- Match the subagent's primary domain + +Examples: +- `test.md` - Testing framework expert +- `pgtle.md` - pg_tle extension expert +- `subagent-expert.md` - Subagent creation expert (this file) +- `subagent-tester.md` - Subagent testing expert + +### 7. Integration with Other Subagents + +**Avoid Duplication:** +- Don't duplicate knowledge that belongs in another subagent +- Reference other subagents when knowledge overlaps +- Keep each subagent focused on its domain + +**Cross-References:** +- Link to related subagents when helpful +- Use consistent terminology across subagents +- Ensure related subagents don't contradict each other + +### 8.

Checks if foundation exists (.envs/foundation/.bats-state/.foundation-complete) -# 2. If foundation exists but is > 10 seconds old, warns it may be stale -# (important when testing changes to pgxntool itself) -# 3. If foundation doesn't exist, runs foundation.bats to create it -# 4. Copies foundation TEST_REPO to the target environment -# -# This allows any test to be run individually without manual setup - the test -# will automatically ensure foundation exists before running. -# -# Usage: -# ensure_foundation "$TEST_DIR" -# -# Example in test file: -# setup_file() { -# load_test_env "my-test" -# ensure_foundation "$TEST_DIR" # Ensures foundation exists and copies it -# # Now TEST_REPO exists and we can work with it -# } -ensure_foundation() { - local target_dir="$1" - if [ -z "$target_dir" ]; then - error "ensure_foundation: target_dir required" - fi - - local foundation_dir="$TOPDIR/.envs/foundation" - local foundation_state="$foundation_dir/.bats-state" - local foundation_complete="$foundation_state/.foundation-complete" - - debug 2 "ensure_foundation: Checking foundation state" - - # Check if foundation exists - if [ -f "$foundation_complete" ]; then - debug 3 "ensure_foundation: Foundation exists, checking age" - - # Get current time and file modification time - local now=$(date +%s) - local mtime - - # Try BSD stat first (macOS), then GNU stat (Linux) - if stat -f %m "$foundation_complete" >/dev/null 2>&1; then - mtime=$(stat -f %m "$foundation_complete") - elif stat -c %Y "$foundation_complete" >/dev/null 2>&1; then - mtime=$(stat -c %Y "$foundation_complete") - else - # stat not available or different format, skip age check - debug 3 "ensure_foundation: Cannot determine file age (stat unavailable)" - mtime=$now - fi - - local age=$((now - mtime)) - debug 3 "ensure_foundation: Foundation is $age seconds old" - - if [ $age -gt 10 ]; then - out "WARNING: Foundation is $age seconds old, may be out of date." - out " If you've modified pgxntool, run 'make foundation' to rebuild." - fi - else - debug 2 "ensure_foundation: Foundation doesn't exist, creating..." - out "Creating foundation environment..." - - # Run foundation.bats to create it - # OK to fail: grep returns non-zero if no matches, but we want empty output in that case - "$BATS_TEST_DIRNAME/../test/bats/bin/bats" "$BATS_TEST_DIRNAME/foundation.bats" | { grep '^#' || true; } >&3 - local status=${PIPESTATUS[0]} - - if [ $status -ne 0 ]; then - error "Failed to create foundation environment" - fi - - out "Foundation created successfully" - fi - - # Copy foundation TEST_REPO to target environment - local foundation_repo="$foundation_dir/repo" - local target_repo="$target_dir/repo" - - if [ ! -d "$foundation_repo" ]; then - error "Foundation repo not found at $foundation_repo" - fi - - debug 2 "ensure_foundation: Copying foundation to $target_dir" - # Use rsync to avoid permission issues with git objects - rsync -a "$foundation_repo/" "$target_repo/" - - if [ ! -d "$target_repo" ]; then - error "Failed to copy foundation repo to $target_repo" - fi - - # Also copy fake_repo if it exists (needed for git push operations) - local foundation_fake="$foundation_dir/fake_repo" - local target_fake="$target_dir/fake_repo" - if [ -d "$foundation_fake" ]; then - debug 3 "ensure_foundation: Copying fake_repo" - rsync -a "$foundation_fake/" "$target_fake/" - fi - - debug 3 "ensure_foundation: Foundation copied successfully" -} - -# vi: expandtab sw=2 ts=2
