Software Development Skills

Explore external codebases to answer questions about their architecture, implementation, and behavior. Use when needing to understand how a library, framework, or external project works internally — for debugging dependency behavior, making architecture decisions, understanding API internals, or learning implementation patterns. Triggers on repo slugs or URLs with questions (e.g., "how does X implement Y"), "look at the source of", "check how [dep] works", "explore [repo]", or when answering a question would benefit from reading source code of an external project. Also invoke proactively when the user's question about a dependency could be answered more accurately by reading the actual source rather than relying on training data.

Conventions for working in the coppermind vault - write zones, task format, wiki tiers, redaction policy, and query gotchas. Use whenever reading or writing vault content, managing tasks, filing todos, updating project pages, or writing digest/pipeline output into the vault.

Design and tune cursor movement for Remotion or product-demo videos. Use when adding cursor paths, hover states, click rings, cursor preview compositions, or fixing cursor target alignment.

Parallel read-only multi-agent review of a current git diff or explicit file scope to find behavioral regressions, security or privacy risks, performance or reliability issues, and contract or test coverage gaps. Use when the user asks for a review swarm, parallel review, diff review, regression review, security review, or wants high-signal issues plus a prioritized fix path without editing files.
