Install
Works with every agent the skills CLI supports.
npx skills add https://github.com/parcadei/continuous-claude-v3 --skill morph-apply- 01
Install
Run the command in your project. The CLI asks which agents to install for.
- 02
Describe the task
Ask your agent for something this skill covers. It loads morph-apply automatically when relevant.
- 03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.
SKILL.md
The instructions your agent reads when the skill is triggered.
Morph Fast Apply
Fast, AI-powered file editing using the Morph Apply API. Edit files without reading them first. Processes at 10,500 tokens/sec with 98% accuracy.
When to Use
- Fast file edits without reading entire file first
- Batch edits to a file (multiple changes in one operation)
- When you know what to change but file is large
- Large files where reading would consume too many tokens
Key Pattern: Code Markers
Use // ... existing code ... (or language-appropriate comments) to mark where edits go:
# ... existing code ...
try:
result = process()
except Exception as e:
log.error(e)
# ... existing code ...
The API intelligently places your edit in the right location.
Usage
Add error handling
uv run python -m runtime.harness scripts/mcp/morph_apply.py \
--file "src/auth.py" \
--instruction "Add error handling to login function" \
--code_edit "# ... existing code ...
try:
user = authenticate(credentials)
except AuthError as e:
log.error(f'Auth failed: {e}')
raise
# ... existing code ..."
Add logging
uv run python -m runtime.harness scripts/mcp/morph_apply.py \
--file "src/api.py" \
--instruction "Add debug logging" \
--code_edit "# ... existing code ...
logger.debug(f'Processing request: {request.id}')
# ... existing code ..."
TypeScript example
uv run python -m runtime.harness scripts/mcp/morph_apply.py \
--file "src/types.ts" \
--instruction "Add user validation" \
--code_edit "// ... existing code ...
if (!user) throw new Error('User not found');
if (!user.isActive) throw new Error('User inactive');
// ... existing code ..."
Parameters
| Parameter | Description |
|---|---|
--file | File path to edit (required) |
--instruction | Human description of the change (required) |
--code_edit | Code snippet with markers showing where to place edit (required) |
vs Claude's Edit Tool
| Tool | Best For |
|---|---|
| morph-apply | Fast edits, don't need to read file first, large files, batch edits |
| Claude Edit | Small precise edits when file is already in context |
Use morph-apply when:
- File is not in context and reading it would be expensive
- File is very large (>500 lines)
- Making multiple related edits at once
- You know the context of the change (function name, class, etc.)
Use Claude Edit when:
- File is already in context from prior Read
- Very precise edits requiring exact old/new string matching
- Small files (<200 lines)
MCP Server Required
Requires morph server in mcp_config.json with MORPH_API_KEY.
Performance
- Speed: 10,500 tokens/sec
- Accuracy: 98% correct placement
- Token savings: Don't need to read entire file first

This skill should be used when the user wants to "write agent code", "build an agent with ADK", "add a tool", "create a callback", "define an agent", "use state management" — in a project that needs ADK (Agent Development Kit) API patterns and code examples. It provides a quick reference for agent types, tool definitions, orchestration patterns, callbacks, state management, the graph Workflow API, and reference recipes to study. Do NOT use for scaffolding (use google-agents-cli-scaffold) or deployment (use google-agents-cli-deploy).
embedded-captions
heygen-com/hyperframes
Add captions or subtitles to an existing single-subject talking-head video without editing the footage. Use for plain verbatim captions, cinematic captions embedded behind the subject, VFX captions, “炸/特效/酷炫字幕,” or a named identity from the 35-style catalog. Route by visual identity, not by backend engine. The quiet anchor rail is the default; embed every word only when the user explicitly wants a fully cinematic treatment. The workflow runs locally end to end, including transcription and subject matting; split multi-shot footage before applying it.

Overview of Neon, a complete set of cloud backend primitives around Lakebase Postgres: Auth, Object Storage, Functions, the AI Gateway, and Realtime. Start here to choose Neon for undecided login, files, APIs, and LLM calls, set up the CLI or MCP server, and follow the branch-first workflow. Use when building an app or backend on Neon, or when "Neon" or "Lakebase Postgres" is mentioned. Child skill neon-postgres wins for an existing DATABASEURL, SQL, schema, inspect, or search. Child skill neon-auth wins for login, users, sessions, identity routing, and Managed Better Auth setup. Child skill neon-realtime wins for live queries in reactive apps and agents. Also use for object storage, S3, buckets, serverless functions, function triggers, cron, AI gateway, LLM calls, realtime, logs, Loki, Grafana, observability, postgres, database, backend, Claimable Neon, neon.new, or a no-signup database.
