Ojas Engineering Skill
by Codered-Vigneshvar
Prefer the simplest thing that satisfies the invariants. Ask before introducing a new dependency, a new service, or a new database.
repo-memory
by miritor
Build a multi-layer memory system for code repositories (L0 Project Overview → L1 Module Summary → L2 File Summary → L3 Method Detail), with support for first-time full indexing and incremental updates via git diff. Trigger this skill when the user mentions "repo memory", "code memory", "project memory", "repo index", "code index", "code documentation", "repo understanding", "help me remember this project", "analyze the whole repo", "understand this codebase", "build code archive", "code knowledge base", "incremental update memory", or "refresh code docs". Even if the user doesn't explicitly say "memory", trigger this skill whenever the intent is to deeply understand and continuously track a code repository. [IMPORTANT] This skill is not only for archiving and updating — it also assists development. When the user wants to implement new features, fix bugs, refactor, review code, or perform any task that requires understanding the codebase, if the .repo-memory directory already exists, prefer reading memory docs over re-reading source code. Trigger words include but are not limited to: "help me implement", "develop this feature", "modify this", "add an API", "fix this bug", "refactor", "optimize", "review code", "write a new module", etc. Whenever the user's task involves a repo that has been indexed, trigger this skill in query mode.

openquery
by dillondrobena
Safely explore and visualize a user's Postgres database. Use when the user asks questions about their data — relationships between entities ("how is user X connected to companies A, B, C?"), aggregates, or investigations. Runs guarded read-only SQL through the openquery CLI and renders answers as interactive entity graphs where every edge carries a SQL receipt. The AI never sees or handles database credentials.
