agentic-ai-system-course: Skill for Claude Code

.claude/skills/agentic-system-reviewer/SKILL.md

agentic-system-reviewer is a skill for Claude Code from bryanyzhu/agentic-ai-system-course. It costs 50 tokens per session (1,917 once invoked), scanned A, original, MIT.

A reviewer for agent-system plans, unfinished ideas, and code. Agent systems are software that can plan work, use tools, keep context, delegate tasks, or act on triggers.

In plain words
What is it for?
Use it to review agent PRDs, implementation plans, tool use, memory, delegation, proactive actions, and production readiness.
Why use it?
It checks whether the design fits its intended scope and whether its quality matches the risks of the system being built.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

agentic-system-reviewer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/suggest-chapters.mjs), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Agentic System Reviewer

Overview

Review the provided docs and code against the course, but only after reconstructing the user's goal, project scope, risk level, and archetype. The review must be course-grounded, scope-aware, and evidence-backed.

Core principle: do not grade a weekend prototype like an enterprise workflow control plane, and do not wave through production autonomy like a toy.

When To Use

Use this skill for:

  • PRDs, design docs, implementation plans, or idea files for agentic systems.
  • Codebases or diffs implementing agent loops, tools, memory, planning, delegation, connectors, proactive triggers, or self-improvement.
  • Requests like "review this against the course", "is this agent design good?", "what chapters does this miss?", "check my PRD/code", or "is this production-ready?"

Do not use this skill for ordinary code review with no agent-system concern. Use the normal code-review workflow for that.

Required Resources

Resolve these paths relative to this SKILL.md. Load only what is needed:

  • references/scope-intake.md - mandatory before review.
  • references/chapter-rubric.md - mandatory after scope is known; read the relevant chapter rows.
  • references/report-template.md - mandatory before writing the final report.
  • scripts/suggest-chapters.mjs - optional helper to seed chapter selection from files; never treat it as authoritative.

Review Flow

Follow this order: read provided docs, inspect provided code, write the scope ledger, ask or assume explicitly for material unknowns, select up to 6 primary chapters, open those course files, then write the findings-first report.

Non-Negotiables

  1. Read user-provided docs first. If a PRD, plan, README, idea file, issue, transcript, or design note exists, it defines intent until contradicted.
  2. If code is provided, read enough of the codebase to understand architecture, boundaries, data flow, and actual behavior. At minimum, inspect the entry point, loop/orchestrator, tool definitions, prompt/context builder, state/memory/persistence files, connectors, and tests/evals when present. If the provided code is under 500 lines, read all of it. Note unread directories or files in the ledger.
  3. Establish and record scope before critique. Include project type, users, stakes, archetype, current maturity, and worst plausible mistake.
  4. Ask before reviewing when any material unknown touches users, data scope, autonomy, external actions, or production readiness. If the user declines, run an assumption-led review that clearly marks unresolved scope and confidence.
  5. Read relevant course chapters before citing them. Naming chapters from memory is not enough.
  6. Calibrate rigor. Side projects still need clear loops and tool contracts, but not full multi-tenant ops. Production systems need explicit safety, state, observability, and approval surfaces.
  7. Findings must include evidence, course reference, impact, and suggested fix. In the final report, the Findings section precedes Strengths unless there are no issues.
  8. If reference systems are cloned under references/ (e.g., OpenCode, Hermes Agent, OpenClaw, Paperclip), use them to ground findings with concrete file:line evidence for the pattern. Do not invent paths for references that are not cloned; describe the pattern from the chapter notes instead.

4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
