name	embed-content
description	Use when you need to manage project embeddings - embed skills, agents, commands, and MCP tools for semantic discovery. Handles rate limiting, incremental updates, and status reporting. Do NOT use if you just want to search for content - use the semantic router directly instead.

Embed Content

Overview

Manage embeddings for project-local content including skills, agents, commands, and MCP tools. Enables semantic search and discovery of project-specific items.

Core principle: Make project content discoverable via semantic search.

Trigger: /popkit:project embed command or auto-invoked by generators

Arguments

Flag	Description
`--status`	Show embedding status without embedding
`--force`	Re-embed all content (ignore cache)
`--export`	Export embeddings to .claude/tool_embeddings.json
`--type <type>`	Only embed specific type: `skill`, `agent`, `command`, `tool`

Process

Step 1: Discover Content

Scan project for embeddable items:

import sys
from pathlib import Path

# No longer needed - install popkit-shared instead
from embedding_project import scan_project_items

# Scan locations:
# - .claude/skills/*/SKILL.md      → project-skill
# - .claude/agents/*/AGENT.md      → project-agent
# - .claude/commands/*.md          → project-command
# - .generated/skills/*/SKILL.md   → generated-skill
# - .generated/agents/*/AGENT.md   → generated-agent
# - MCP tool definitions            → mcp-tool

items = scan_project_items(Path.cwd())
print(f"Found {len(items)} embeddable items")

Step 2: Check Status

Compare against embedding store:

from embedding_project import get_project_embedding_status

status = get_project_embedding_status()

# Returns:
# - total_items: Number of items found
# - embedded_items: Number already embedded
# - stale_items: Number with changed content
# - missing_items: Number not yet embedded
# - by_type: Breakdown by source type

Step 3: Compute Embeddings

Via Voyage AI with rate limiting:

from embedding_project import embed_project_items

# Respects rate limits:
# - 3 requests per minute (21s delay between batches)
# - Up to 50 items per batch
# - Progress reporting

result = embed_project_items(
    project_root=Path.cwd(),
    force=False  # Set True to re-embed unchanged items
)

print(f"Embedded: {result['embedded']}")
print(f"Skipped: {result['skipped']}")
print(f"Errors: {result['errors']}")

Step 4: Export for MCP

Optionally export embeddings for MCP server:

import json
from datetime import datetime
from pathlib import Path

def export_tool_embeddings(tools: list, output_path: str):
    """Export embeddings for MCP semantic search."""
    output = {
        "generated_at": datetime.now().isoformat(),
        "model": "voyage-3.5",
        "dimension": len(tools[0]["embedding"]) if tools else 0,
        "tools": tools
    }

    Path(output_path).parent.mkdir(parents=True, exist_ok=True)
    Path(output_path).write_text(json.dumps(output, indent=2))

Rate Limiting

The skill respects Voyage AI rate limits:

Limit	Value	Handling
Requests per minute	3	21-second delay between batches
Items per request	50	Batch items automatically
Tokens per request	120,000	Descriptions typically small

Typical Times:

10 items: ~5 seconds (1 batch)
30 items: ~25 seconds (1 batch + delay)
100 items: ~1 minute (2 batches + delays)

Error Handling

Error	Handling
No API key	Report and skip embedding, suggest setting VOYAGE_API_KEY
Rate limit hit	Wait and retry automatically
Network error	Report item, continue with others
Invalid content	Skip item, report in summary

Integration

Uses:

hooks/utils/embedding_project.py - Core embedding logic
hooks/utils/voyage_client.py - Voyage API client
hooks/utils/embedding_store.py - SQLite storage

Called by:

/popkit:project embed - Manual invocation
/popkit:project generate - Final pipeline step
pop-skill-generator - After creating skills
pop-mcp-generator - After creating MCP server

Enables:

Semantic search for project content
Natural language tool discovery
Cross-project skill discovery
Priority boost for project items in routing

Examples

# Check what needs embedding
/popkit:project embed --status

# Embed all new/changed items
/popkit:project embed

# Force re-embed everything
/popkit:project embed --force

# Embed only skills
/popkit:project embed --type skill

# Export for MCP server
/popkit:project embed --export

# Combine: embed and export
/popkit:project embed --export
