See all →The most-installed skills from Aegis, ranked by adoption.
01anti-entropy-governance
Use when touching retiring old logic, collapsing duplicate owners, removing fallbacks, or schema/persistence/source-of-truth boundaries; identify opportunities automatically; destructive execution requires explicit confirmation.
Buildfrom Aegis02communicating-concisely
Use when the user asks for caveman mode, fewer tokens, brief responses, compressed communication, or otherwise explicitly requests a much shorter answer.
Buildfrom Aegis03receiving-code-review
Use when receiving code review feedback before implementing suggestions, especially when feedback is unclear, risky, disputed, or technically questionable.
Buildfrom Aegis04requesting-code-review
Use when requesting independent code review, after implementation slices, before merging high-risk work, or when verification exposes evidence, baseline, architecture, compatibility, or retirement uncertainty.
Buildfrom Aegis05systematic-debugging
Use when encountering a bug, test failure, or unexpected behavior, before proposing fixes
Buildfrom Aegis06using-aegis
Use when starting a turn or checking Aegis skill routing.
Buildfrom Aegis07verification-before-completion
Use when about to claim work is complete, fixed, passing, verified, release-ready, or ready to commit, merge, publish, or hand off.
Buildfrom Aegis08writing-plans
Use when you have an approved spec or written requirements for a multi-step task that needs a durable plan document before touching code. Small, single-owner, or fast-path tasks do not need this skill.
Buildfrom Aegis09writing-skills
Use when creating new skills, editing existing skills, or verifying skills work before deployment
Buildfrom Aegis10recording-architecture-decisions
Use when the user asks to create, write, update, amend, supersede, or evaluate an ADR, architecture decision record, durable architecture decision, decision log, or baseline sync after architecture-changing work.
Buildfrom Aegis11brainstorming
Use when defining ambiguous or high-complexity new features, product behavior, UI/component design, architecture choices, contract changes, or when grilling/pressure-testing a plan or design. Routine small requests stay on the fast path.
Buildfrom Aegis12finishing-a-development-branch
Use when verified work needs integration or cleanup of an existing task-created branch/worktree, or the user explicitly requests merge, PR, or branch lifecycle handling.
Buildfrom Aegis13dispatching-parallel-agents
Use when facing 2+ independent tasks without a written plan, with no shared state or sequential dependencies, where parallel delegation beats inline cost; otherwise inline. Planned tasks use subagent-driven-development.
Buildfrom Aegis14establishing-project-context
Use when the user asks to establish shared project language, or project work exposes a conflicting, renamed, or deprecated domain term that needs active semantic modeling. Routine small tasks stay on the fast path.
Buildfrom Aegis15first-principles-review
Use when asked for first-principles or Occam's-razor review, or when high-risk decisions involve competing constraints, fallback growth, duplicate owners, or architecture direction risk. Ordinary bug fixes stay on the fast path.
Buildfrom Aegis16goal-framing
Use when the user explicitly sets an Aegis goal with /aegis-goal, Aegis goal:, or asks to define goal, success evidence, stop condition, or task boundaries before work.
Buildfrom Aegis17executing-plans
Use when executing a written implementation plan across sessions or with review checkpoints. Small or single-slice plans stay inline. For same-session independent tasks, use subagent-driven-development instead.
Buildfrom Aegis18subagent-driven-development
Use when executing a written implementation plan with independent tasks in the current session where delegation beats inline coordination cost; otherwise inline. Ad-hoc 2+ tasks without a plan use dispatching-parallel-agents.
Buildfrom Aegis19test-driven-development
Use when the user explicitly requests strict or test-first TDD, or when the current conversation already contains an explicit `TDD Route: strict` decision from another Aegis workflow.
Buildfrom Aegis20update-aegis
Use when the user says `aegis:update`, asks to update or upgrade an installed Aegis method-pack, wants the latest Aegis version, or asks whether Aegis is current on this host.
Buildfrom Aegis21using-git-worktrees
Use when a coding task needs a concurrent checkout, unrelated dirty state blocks safe branch switching, or the user or repository explicitly requires a worktree.
Buildfrom Aegis22long-task-continuation
Use when a task is multi-step, may span context resets or sessions, uses subagents, or risks losing state before completion.

About this source
skills-hub.ai mirrors skills from 90+ official GitHub repositories every day. Each imported skill is parsed from a SKILL.md file in the source repo, gets a security scan and quality score on import, and links back to its upstream source of truth.

Aegis skills, frequently asked
What are Aegis skills?
Aegis skills are AI coding skills published by Aegis (Make AI coding agents architecture-aware: baseline-first, evidence-verified, drift-checked, and safe across long tasks. 22 skills.) and mirrored daily on skills-hub.ai. They are SKILL.md files that follow the open Agent Skills standard, so they work in Claude Code, Cursor, Codex CLI, Windsurf, Copilot, and any MCP-compatible tool.
How many Aegis skills are available?
skills-hub.ai indexes 22 skills from Aegis, synced daily from the upstream GitHub repository (https://github.com/GanyuanRan/Aegis).
How do I install a Aegis skill?
Run `npx @skills-hub-ai/cli install <skill-slug>` in your project. The CLI writes the SKILL.md to the right directory for your AI tool and adds it to your `.skills.json` lockfile so your team gets the same skills at the same versions.
Are these official Aegis skills?
Yes. Every skill from this source is mirrored from Aegis's own GitHub repository (https://github.com/GanyuanRan/Aegis). Each skill page links back to the upstream source of truth, so you can verify the original.
