Explore and understand how the codebase works. Use when user asks "how does the authentication work", "where is the API endpoint defined", "show me how data flows through the system", "explain this module's architecture", "trace the request from controller to database", or "I need to understand this feature before making changes".

What this skill does


# Codebase Explorer

Build comprehensive understanding of codebase areas before implementation or to answer questions about how things work.

## When to Activate

- User asks "how does X work?"
- User wants to understand existing code
- User asks where something is implemented
- Before planning any feature (preparation step)
- User asks about architecture or patterns
- User wants to trace data flow or execution

## Quick Process

1. **Parse the request** — extract `topic`, `files` (optional), and `focus` (optional) from the user's message
2. **Delegate** — invoke context-loader-agent with the extracted parameters
3. **Present findings** — format the agent output using the Output Format section below

## Input Parsing

Extract from user's request:

- `topic`: Main area/feature/component to explore
- `files`: Specific files mentioned (optional)
- `focus`: Particular aspects to emphasize (optional)

## Delegation

Invoke **context-loader-agent** and pass the extracted parameters:

- `topic`: the main area to explore
- `files`: specific files mentioned (omit if none)
- `focus`: the aspect to emphasize (omit if not specified)

The agent handles file discovery, dependency tracing, pattern identification, and analysis.

## Output Format

Return structured analysis:

- **Summary**: Executive overview of the area
- **Key Components**: Core files and responsibilities
- **Patterns**: Conventions to follow
- **Dependencies**: External integrations
- **Data Flow**: How data moves through the system
- **Gotchas**: Non-obvious behaviors and pitfalls
- **Implementation Notes**: Key considerations for new work

## Examples

```
"How does the authentication flow work?"
"Where is the API rate limiting implemented?"
"Show me how data flows from the UI to the database"
"Explain the plugin architecture before I add a new one"
"Trace a request from the controller to the database"
```

## Workflow Integration

This is **Step 1** of the implementation workflow:

1. **Explore** (this) → 2. Plan → 3. Review → 4. Execute

After exploring, context is automatically available for `/plan` or the `plan-implementation` skill.

## Detailed Reference

For exploration strategies and patterns, see [exploration-guide.md](exploration-guide.md).

jfrog

Included

Interact with the JFrog Platform via the JFrog CLI and REST/GraphQL APIs. Use this skill when the user wants to manage Artifactory repositories, upload or download artifacts, manage builds, configure permissions, manage users and groups, work with access tokens, configure JFrog CLI servers, search artifacts, manage properties, set up replication, manage JFrog Projects, run security audits or scans, look up CVE details, query exposures scan results from JFrog Advanced Security, manage release bundles and lifecycle operations, aggregate or export platform data, or perform any JFrog Platform administration task. Also use when the user mentions jf, jfrog, artifactory, xray, distribution, evidence, apptrust, onemodel, graphql, workers, mission control, curation, advanced security, exposures, or any JFrog product name.

cupynumeric-migration-readiness

Included

Pre-migration readiness assessor for porting NumPy to cuPyNumeric. Use BEFORE substantial porting work begins when the user asks whether code will scale on GPU, whether they should migrate to cuPyNumeric, which NumPy patterns transfer cleanly, what must be refactored before porting, or mentions pre-port assessment, scaling analysis, or refactor planning. Inspect the user's source code, look up NumPy usage, cross-reference the cuPyNumeric API support manifest, and distinguish distributed-scaling-friendly patterns from blockers such as unsupported APIs, scalar synchronization, host round-trips, Python/object-heavy control flow, shape/data-dependent branching, and in-place mutation hazards. Produce a verdict of READY, LIGHT REFACTOR, SIGNIFICANT REFACTOR, or NOT RECOMMENDED, with concrete refactor pointers.

alibabacloud-data-agent-skill

Included

Invoke Alibaba Cloud Apsara Data Agent for Analytics via CLI to perform natural language-driven data analysis on enterprise databases. Data Agent for Analytics is an intelligent data analysis agent developed by Alibaba Cloud Database team for enterprise users. It automatically completes requirement analysis, data understanding, analysis insights, and report generation based on natural language descriptions. This tool supports: discovering data resources (instances/databases/tables) managed in DMS, initiating query or deep analysis sessions, real-time progress tracking, and retrieving analysis conclusions and generated reports. Use this Skill when users need to query databases, analyze data trends, generate data reports, ask questions in natural language, or mention "Data Agent", "data analysis", "database query", "SQL analysis", "data insights".

token-optimizer

Included

Reduce OpenClaw token usage and API costs through smart model routing, heartbeat optimization, budget tracking, and native 2026.2.15 features (session pruning, bootstrap size limits, cache TTL alignment). Use when token costs are high, API rate limits are being hit, or hosting multiple agents at scale. The 4 executable scripts (context_optimizer, model_router, heartbeat_optimizer, token_tracker) are local-only — no network requests, no subprocess calls, no system modifications. Reference files (PROVIDERS.md, config-patches.json) document optional multi-provider strategies that require external API keys and network access if you choose to use them. See SECURITY.md for full breakdown.

resend-cli

Included

Use this skill when the task is specifically about operating Resend from an AI agent, terminal session, or CI job via the official resend CLI: installing/authenticating the CLI, sending/listing/updating/cancelling emails, batch sends, domains and DNS, webhooks and local listeners, inbound receiving, contacts, topics, segments, broadcasts, templates, API keys, profiles, or debugging Resend CLI/API failures. Trigger on mentions of Resend CLI, `resend`, `resend doctor`, `resend emails send`, `resend domains`, `resend webhooks listen`, `resend emails receiving`, or agent-friendly terminal automation.
