Prad Nukala 6406208b35 shell: fish functions -> ~/.local/bin executables + bash/zsh ports; manage ~/.agents
- 16 cross-shell utilities converted to sh/bash chezmoi executables:
  ai c2p cp-appid extract_agents fab gdc gh-sonr-org-migrate ghg-clone
  ghn gho git-summary launch_omp_livediff_overlay lc-elir mdcp mdp pj
  (ghg-clone not named ghg: unrelated cargo binary owns that name)
- cwd/history helpers stay per-shell: yy c cd clip-last + ghg/ghn/gho
  cd-wrappers in bash/functions/ and zsh/functions/, loaded by rc files
- fish keeps only shell-state functions; converted ones now hit PATH
- cp-appid ignore gating moved to .local/bin path
- dot_agents/skills: 82 skills materialized from dotstate storage so
  dot_claude skill symlinks resolve on fresh bootstrap; dotstate
  profile/symlinks.json released .agents/skills .bashrc .zshrc

# AI Search Gotchas
## Type Safety
**Timestamp precision:** Use seconds (10-digit), not milliseconds.
```typescript
const nowInSeconds = Math.floor(Date.now() / 1000); // Correct
```
**Folder prefix matching:** Use `gte` for "starts with" on paths.
```typescript
filters: { column: "folder", operator: "gte", value: "docs/api/" } // Matches nested
```
## Filter Limitations
| Limit | Value |
|-------|-------|
| Max nesting depth | 2 levels |
| Filters per compound | 10 |
| `or` operator | Same column, `eq` only |
**OR restriction example:**
```typescript
// ✅ Valid: same column, eq only
{ operator: "or", filters: [
{ column: "folder", operator: "eq", value: "docs/" },
{ column: "folder", operator: "eq", value: "guides/" }
]}
```
## Indexing Issues
| Problem | Cause | Solution |
|---------|-------|----------|
| File not indexed | Unsupported format or >4MB | Check format (.md/.txt/.html/.pdf/.doc/.csv/.json) |
| Index out of sync | 6-hour index cycle | Wait or use "Force Sync" (30s rate limit) |
| Empty results | Index incomplete | Check dashboard for indexing status |
## Auth Errors
| Error | Cause | Fix |
|-------|-------|-----|
| `AutoRAGUnauthorizedError` | Invalid/missing token | Create Service API token with AI Search permissions |
| `AutoRAGNotFoundError` | Wrong instance name | Verify exact name from dashboard |
## Performance
**Slow responses (>3s):**
```typescript
// Add score threshold + limit results
ranking_options: { score_threshold: 0.5 },
max_num_results: 10
```
**Empty results debug:**
1. Remove filters, test basic query
2. Lower `score_threshold` to 0.1
3. Check index is populated
## Limits
| Resource | Limit |
|----------|-------|
| Instances per account | 10 |
| Files per instance | 100,000 |
| Max file size | 4 MB |
| Index frequency | 6 hours |
## Anti-Patterns
**Use env vars for instance names:**
```typescript
const answer = await env.AI.autorag(env.AI_SEARCH_INSTANCE).aiSearch({...});
```
**Handle specific error types:**
```typescript
if (error instanceof AutoRAGNotFoundError) { /* 404 */ }
if (error instanceof AutoRAGUnauthorizedError) { /* 401 */ }
```
