Aegis
Make AI coding agents architecture-aware: baseline-first, evidence-verified.
AI coding agents guess, break architecture, and say "done" with no proof. Aegis is a Method Pack (runtime-ready, not a runtime core) that makes agents work like disciplined engineers: baseline-first planning, verification-before-completion, plus TDD, systematic-debugging, and collaboration workflows. Simple tasks stay on fast-path, ceremony only when needed. One pack, every host: Codex, Claude Code, OpenCode, Kimi and other skill-aware hosts. v2.9.6 fixes Codex 0.147 frozen skill-path spellings and binds delegated work back to baseline/checkpoint instead of trusting child output. Bounded evidence: frozen A/B benchmark contract pass 61.67% → 93.33%, unsafe 13.33% → 0%. Advisory only, not completion authority.

Continuous scanner CI not detected
This plugin remains listed. Its overall trust score is reduced by 10% because security checks are not maintained in the source repository's CI.
Optional: maintain the scanner in the source repository's CI to receive the full trust score. Listing does not require that change.
Verified badge not detected
Add the HOL verified badge to the repository README to score +2% trust. Plugin owners can open that pull request from Guard Plugins.

Skills
23 SKILL.md files ship with this plugin. Preview, copy, or download each one, then install them with the Skills CLI.
anti-entropy-governance
skills/anti-entropy-governance/SKILL.md
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.
SKILL.md content is not in this snapshot. Open the raw file to copy it from the source repository.
brainstorming
skills/brainstorming/SKILL.md
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.
SKILL.md content is not in this snapshot. Open the raw file to copy it from the source repository.
communicating-concisely
skills/communicating-concisely/SKILL.md
Use when the user asks for caveman mode, fewer tokens, brief responses, compressed communication, or otherwise explicitly requests a much shorter answer.
SKILL.md content is not in this snapshot. Open the raw file to copy it from the source repository.
dispatching-parallel-agents
skills/dispatching-parallel-agents/SKILL.md
Use when facing 2+ independent tasks without a written plan, with no conflicting shared mutable state or sequential dependencies, where parallel delegation beats inline cost; otherwise inline. Planned tasks use subagent-driven-development.
SKILL.md content is not in this snapshot. Open the raw file to copy it from the source repository.
establishing-project-context
skills/establishing-project-context/SKILL.md
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.
SKILL.md content is not in this snapshot. Open the raw file to copy it from the source repository.
executing-plans
skills/executing-plans/SKILL.md
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.
SKILL.md content is not in this snapshot. Open the raw file to copy it from the source repository.
finishing-a-development-branch
skills/finishing-a-development-branch/SKILL.md

first-principles-review
skills/first-principles-review/SKILL.md
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.
SKILL.md content is not in this snapshot. Open the raw file to copy it from the source repository.
goal-framing
skills/goal-framing/SKILL.md

receiving-code-review
skills/receiving-code-review/SKILL.md
Use when receiving code review feedback before implementing suggestions, especially when feedback is unclear, risky, disputed, or technically questionable.

SKILL.md content is not in this snapshot. Open the raw file to copy it from the source repository.
requesting-code-review
skills/requesting-code-review/SKILL.md
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.

subagent-driven-development
skills/subagent-driven-development/SKILL.md
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.
SKILL.md content is not in this snapshot. Open the raw file to copy it from the source repository.
systematic-debugging
skills/systematic-debugging/SKILL.md
Use when encountering a bug, test failure, or unexpected behavior, before proposing fixes

ui-ux-governance
skills/ui-ux-governance/SKILL.md
Use when designing, changing, or reviewing user-facing interfaces or interaction flows, including API changes that alter visible states or recovery. Backend-only work without user-facing effects stays on its existing route.
SKILL.md content is not in this snapshot. Open the raw file to copy it from the source repository.
update-aegis
skills/update-aegis/SKILL.md

using-aegis
skills/using-aegis/SKILL.md

SKILL.md content is not in this snapshot. Open the raw file to copy it from the source repository.
using-git-worktrees
skills/using-git-worktrees/SKILL.md

SKILL.md content is not in this snapshot. Open the raw file to copy it from the source repository.
verification-before-completion
skills/verification-before-completion/SKILL.md
Use when about to claim work is complete, fixed, passing, verified, release-ready, or ready to commit, merge, publish, or hand off.
SKILL.md content is not in this snapshot. Open the raw file to copy it from the source repository.
writing-plans
skills/writing-plans/SKILL.md
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.
SKILL.md content is not in this snapshot. Open the raw file to copy it from the source repository.
writing-skills
skills/writing-skills/SKILL.md
Use when creating new skills, editing existing skills, or verifying skills work before deployment
