Claude: Default to Projects, Use Skills Sparingly
Use Projects for focused, activity-specific workspaces to avoid AI distraction; reserve Skills for reusable processes across chats/projects, limiting to 13-15 active ones in browser to prevent confusion.
Qualify Use Cases Before Building Projects or Skills
Only create Projects or Skills if your task repeats with similar shape (not identical steps) more than once AND demands consistently high-quality outputs. Ad-hoc chats suffice for one-offs or low-stakes work, keeping your setup lean and preventing unnecessary complexity.
Projects excel for scoped activities like client negotiations (e.g., 6 months of materials for one client) or monthly closes, where dropping all relevant files into a dedicated workspace ensures the AI references only that context without dilution. This isolation boosts output quality by eliminating distractions from unrelated files or instructions—crucial when scaling to hundreds of Projects, as each opens in isolation.
Skills suit standardized processes with rigid steps, formats, or outputs, like branded proposals or financial evaluations, reusable across clients without per-project files. They load titles/descriptions in every browser chat (proactively triggering based on context) but pull deeper instructions/files only as needed, optimizing context window usage.
Projects Scale Better Than Skills for Beginners
Start with Projects as your default: they contain custom instructions and knowledge files (browser) or folder contents + cloud.md instructions (desktop app), focusing the AI solely on one activity. Avoid dumping all company files into one Project (e.g., Acme everything)—instead, create separate ones like "Acme Client Updates," "Acme Proposals," and "Acme Contract Review" to maintain laser focus.
In browser, Projects reference uploaded files; in desktop (via folder selection), parent folders expose subfolders, but subfolder chats limit to contents there. This structure scales infinitely without overwhelming the AI, unlike global Skills.
Projects handle client-specific rules (e.g., unique reconciliation categories) paired with Skills for process standardization, yielding precise outputs like monthly financial closes.
Build Skills from Proven Conversations, Limit to Avoid Errors
Never build Skills from scratch—chat until perfect output (5-20 exchanges), then prompt Claude's built-in "Skill Creator" (from Anthropic) to extract the reusable process: "Strip client-specific details, encapsulate procedures/standards/formats into a Skill based on this conversation." This captures what works, making it topic-agnostic.
Skills portable across tools (export from Claude, import to OpenAI alternatives), chainable in Project instructions (e.g., Skill1 → Skill2 → Skill3), and reusable anywhere. Explicitly invoke via /slash command (e.g., /proposal-writer) for control.
Cap browser Skills at 13-15 max: more causes proactive misfires (e.g., confusing client vs. vendor proposals). Desktop mitigates by attaching Skills to subfolders (e.g., finance folder gets only financial Skills). Overloading confuses selection when titles/descriptions overlap.
