explain

explain is a cursor rule for Cursor from VoTruongDanh/Skills-Agent. It costs 59 tokens per session (976 once invoked), scanned A, original, MIT.

A rule set for explaining code, including its logic, architecture, or behavior, at the level the reader needs. It also uses project notes and routes explanations toward backend, frontend, database, security, or documentation concerns when relevant.

In plain words
What is it for?
Use it for code walkthroughs, architecture explanations, behavior questions, and detailed discussions of backend, interface, database, or security code.
Why use it?
It gives explanations a consistent structure and helps avoid describing code without first understanding its context.

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

explain 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 4d ago.

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.

How it starts

The opening of the file, as written. The whole thing — 75 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Memory Protocol

START: Read .ai-memory.md from project root. Check tech stack, architecture notes, past explanations, and domain context. END: Update .ai-memory.md using Memory Compaction Rules with: what was explained, key insights, misconceptions clarified, and follow-ups.

Goal

Help the user deeply understand code, logic, architecture, or behavior — at the level of detail they need.

Agent Routing

  • If explaining backend/API logic → read .kiro/skills/agents/agents/backend-specialist.md and apply its knowledge
  • If explaining UI/component behavior → read .kiro/skills/agents/agents/frontend-specialist.md and apply its knowledge
  • If explaining database schema/queries → read .kiro/skills/agents/agents/database-architect.md and apply its knowledge
  • If explaining security mechanisms → read .kiro/skills/agents/agents/security-auditor.md and apply its knowledge
  • Default → read .kiro/skills/agents/agents/documentation-writer.md for clear, structured explanation

Socratic Gate

Before explaining, verify:

  1. Which file, function, or code block should be explained?
  2. What level of detail? (high-level overview vs line-by-line walkthrough)
  3. What is the user's familiarity level with this area? If any answer is unclear, ASK before proceeding.

Workflow

  1. Read Memory — Load .ai-memory.md for project context, tech stack, and architecture.
  2. Read the target code thoroughly — understand intent, not just syntax.
  3. Identify the explanation scope: single function, module, data flow, or architecture.
  4. Explain at the requested level:
    • High-level: Purpose, inputs/outputs, how it fits in the system.
    • Detailed: Step-by-step logic, control flow, edge cases, design decisions.
    • Line-by-line: What each line does and why.
  5. Highlight non-obvious logic, hidden side effects, and design trade-offs.
  6. Use analogies or diagrams if the concept is complex.
  7. Suggest follow-up topics if relevant (e.g., "you may also want to understand X").
  8. Quality Gate — Read .kiro/skills/_scripts/checklist.md for cross-cutting checks.
  9. Update Memory — Save explanation context and insights to .ai-memory.md.

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.

explain is a cursor rule published in the GitHub repository VoTruongDanh/Skills-Agent (2 stars, last pushed 4mo ago), licensed MIT. It adds 59 tokens to every session and 976 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
