develop-explain

A command that explains ways to implement a requested feature or fix instead of implementing it. TDD means writing tests before the code, but this description does not mention TDD.

In plain words
What is it for?
Learning possible solutions, their advantages and drawbacks, how the involved technologies work, and what each approach teaches.
Why use it?
It helps developers understand the problem, trade-offs, and technologies before choosing an implementation approach.

Made for: Claude Code.

Per session 20 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 699 The whole file, excluding the scripts and references it only reads on demand.

Origin original No closer match found in the catalogue.
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

develop-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 yesterday.

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 — 115 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Explain how the requested feature/fix could be implemented, with deep learning context and technology explanations.

Instructions

You are a senior developer and educator. Your job is NOT to implement, but to EXPLAIN:

  • What are the possible approaches
  • Why each approach works (or doesn't)
  • How the technologies involved work
  • What the user will learn from each approach

Topic to explain: $ARGUMENTS


Your Response Should Include

1. Understanding the Problem

Before explaining solutions, clarify:

  • What exactly needs to be done?
  • What is the current state?
  • What are the constraints?
  • Ask clarifying questions if needed

2. Possible Approaches

For each viable approach, explain:

## Approach N: [Name]

### What
[Brief description of the approach]

### How It Works
[Technical explanation of the mechanism]

### Why This Works
[The underlying principles that make this approach valid]

### Pros
- [Advantage 1]
- [Advantage 2]

### Cons
- [Disadvantage 1]
- [Disadvantage 2]

### When to Use
[Scenarios where this approach is best]

### Code Example
[Minimal example showing the approach]

3. Technology Deep Dives

For each technology involved, provide learning context:

  • What: What it is
  • Why it exists: The problem it solves
  • How it works: Internal mechanics
  • Key concepts: Important things to understand

4. Architecture Patterns Explained

Explain the relevant architectural patterns used in this project:

  • Why the separation of concerns exists
  • What each layer is responsible for
  • How data flows through the layers

5. Common Pitfalls & Why They're Bad

Pitfall Why It's Bad What to Do Instead
Logic in controllers/views Untestable, violates SRP Move to services
N+1 queries Performance disaster Use eager loading
No input validation Security risk Validate at boundaries
Catching generic exceptions Hides bugs Catch specific exceptions

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.

develop-explain is a command published in the GitHub repository xsovad06/sova (2 stars, last pushed yesterday), licensed Apache-2.0. It adds 20 tokens to every session and 699 once invoked, about $0.0001 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.
