audit-context-building

audit-context-building is a skill for Claude Code from iradoweck/antigravity-awesome-skills. It costs 27 tokens per session (2,156 once invoked), scanned A, a copy of audit-context-building, MIT.

A structured way to understand a codebase in fine detail before looking for bugs or security weaknesses. It traces behavior from individual lines and functions through modules and the wider system.

In plain words
What is it for?
Use it to prepare for security audits, architecture reviews, threat modeling, and detailed investigations where the relationships between code components matter.
Why use it?
It reduces mistaken conclusions caused by missing context, hidden assumptions, or jumping to findings too early. It creates a stable picture of how the system works before an audit begins.

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

audit-context-building 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 7d 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.

Deep Context Builder Skill (Ultra-Granular Pure Context Mode)

1. Purpose

This skill governs how Claude thinks during the context-building phase of an audit.

When active, Claude will:

  • Perform line-by-line / block-by-block code analysis by default.
  • Apply First Principles, 5 Whys, and 5 Hows at micro scale.
  • Continuously link insights → functions → modules → entire system.
  • Maintain a stable, explicit mental model that evolves with new evidence.
  • Identify invariants, assumptions, flows, and reasoning hazards.

This skill defines a structured analysis format (see Example: Function Micro-Analysis below) and runs before the vulnerability-hunting phase.


When to Use

Use when:

  • Deep comprehension is needed before bug or vulnerability discovery.
  • You want bottom-up understanding instead of high-level guessing.
  • Reducing hallucinations, contradictions, and context loss is critical.
  • Preparing for security auditing, architecture review, or threat modeling.

Do not use for:

  • Vulnerability findings
  • Fix recommendations
  • Exploit reasoning
  • Severity/impact rating

2. How This Skill Behaves

When active, Claude will:

  • Default to ultra-granular analysis of each block and line.
  • Apply micro-level First Principles, 5 Whys, and 5 Hows.
  • Build and refine a persistent global mental model.
  • Update earlier assumptions when contradicted ("Earlier I thought X; now Y.").
  • Periodically anchor summaries to maintain stable context.
  • Avoid speculation; express uncertainty explicitly when needed.

Goal: deep, accurate understanding, not conclusions.


Rationalizations (Do Not Skip)

Rationalization Why It's Wrong Required Action
"I get the gist" Gist-level understanding misses edge cases Line-by-line analysis required
"This function is simple" Simple functions compose into complex bugs Apply 5 Whys anyway
"I'll remember this invariant" You won't. Context degrades. Write it down explicitly
"External call is probably fine" External = adversarial until proven otherwise Jump into code or model as hostile
"I can skip this helper" Helpers contain assumptions that propagate Trace the full call chain
"This is taking too long" Rushed context = hallucinated vulnerabilities later Slow is fast
