context-layer-generator

context-layer-generator is a skill for Claude Code, Codex from AnkitClassicVision/ankit_shared_skills. It costs 149 tokens per session (1,236 once invoked), scanned A, original, MIT.

An interview-led process for documenting how a software module or service is structured, what its interfaces promise, and why important decisions were made. A module or service is a focused part of a larger application.

In plain words
What is it for?
Use it to document dependencies, users, data flows, deployment details, interface behavior, constraints, and the reasoning behind non-obvious technical decisions.
Why use it?
It makes knowledge that may exist only in developers' heads easier for people and coding agents to understand. It avoids filling gaps with guesses by asking questions when information is unclear.

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

context-layer-generator 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 5d 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 — 105 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Context Layer Generator

Adopt the role of a context engineer — a specialist in making codebases self-describing. Dark code accumulates when comprehension lives only in people's heads. The fix is embedding comprehension into the code through three layers: structural (where), semantic (what), philosophical (why).

This is an interview skill. Ask questions, wait for answers, probe deeper when answers are vague. Do not invent information.

Workflow

1. Opening     → Identify the module, get a brief description
2. Layer 1     → Structural context (dependencies, dependents, data flows, deployment)
3. Layer 2     → Semantic context (behavioral contracts per interface)
4. Layer 3     → Philosophical context (decision reasoning, non-obvious constraints)
5. Confirm     → Ask if anything to add or correct
6. Generate    → Produce three artifacts (read references/artifact-templates.md first)

Opening

Say:

I'm going to help you build three context layers for a module or service — the artifacts that make it self-describing to both humans and AI agents. We'll work through:

  1. Structural (where it sits, what it touches)
  2. Semantic (what its interfaces actually promise)
  3. Philosophical (why it's built this way)

Which module or service do you want to document? Give me its name and a brief description of what it does.

Wait for response before continuing.

Layer 1 — Structural Context

Ask:

  • What does this module depend on? (Services, databases, external APIs, shared libraries, message queues)
  • What depends on this module? (Which services call it, consume its outputs, rely on its state)
  • What data does it read? What data does it write or modify?
  • How is it deployed? (Own service, part of a monolith, serverless function)
  • Does it share anything with other modules? (Caches, databases, file systems, queues)

Probe vague answers. "When you say it talks to the user service — is that a synchronous API call, an event, or a shared database read?" Precision matters; these are the paths where dark code hides.

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.
