* feat(codex): add skill UI metadata

* Use official Trail of Bits logo

* fix: resolve code review findings for PR #175

Codex silently drops the icons as authored: its loader
(codex-rs/core-skills resolve_asset_path) requires icon paths
containing '..' to resolve under <plugin_root>/assets/, and the
repo-root .codex/assets location fails that containment check.
Verified empirically via codex app-server plugin/read: every
iconSmall/iconLarge came back null; only brand_color applied.

P1 fixed:
- Vendor trail-of-bits-mark.svg into plugins/<name>/assets/ for
  all 38 plugins with skills and point every openai.yaml at
  ../../assets/trail-of-bits-mark.svg (the supported plugin-level
  shared asset pattern). Icons now resolve for marketplace
  installs too, since nothing escapes the plugin root.
- Drop the .codex/ additions: .codex/skills/gh-cli/agents/
  openai.yaml resolved nowhere (.codex/skills is not a Codex
  discovery root) and PR #173 removes the whole .codex/ tree

P2 fixed:
- Patch-bump all 38 touched plugins in plugin.json and
  marketplace.json so installed clients pick up the metadata

Verified:
- Static check replicating Codex's resolution algorithm: all 73
  yaml files resolve under their plugin assets/ and exist
- Live codex app-server probe: 71/72 loadable skills report
  resolved iconSmall/iconLarge and brand_color #D83A34
  (claude-in-chrome-troubleshooting fails to load on main due to
  a pre-existing 64-char qualified-name limit, fixed by #173's
  rename; zeroize-audit's manifest mcpServers object is likewise
  a pre-existing Codex incompatibility fixed by #173)
- validate_codex_skills.py, validate_plugin_metadata.py, prek all
  pass

Audit Context Building

Build deep architectural context through ultra-granular code analysis before vulnerability hunting.

Author: Omar Inuwa

When to Use

Use this skill when you need to:

  • Develop deep comprehension of a codebase before security auditing
  • Build bottom-up understanding instead of high-level guessing
  • Reduce hallucinations and context loss during complex analysis
  • Prepare for threat modeling or architecture review

What It Does

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
  • Apply First Principles, 5 Whys, and 5 Hows at micro scale
  • Build and maintain a stable, explicit mental model
  • Identify invariants, assumptions, flows, and reasoning hazards
  • Track cross-function and external call flows with full context propagation

Key Principle

This is a pure context building skill. It does NOT:

  • Identify vulnerabilities
  • Propose fixes
  • Generate proofs-of-concept
  • Assign severity or impact

It exists solely to build deep understanding before the vulnerability-hunting phase.

Installation

/plugin install trailofbits/skills/plugins/audit-context-building

Phases

  1. Initial Orientation - Map modules, entrypoints, actors, and storage
  2. Ultra-Granular Function Analysis - Line-by-line semantic analysis with cross-function flow tracking
  3. Global System Understanding - State/invariant reconstruction, workflow mapping, trust boundaries

Anti-Hallucination Rules

  • Never reshape evidence to fit earlier assumptions
  • Update the model explicitly when contradicted
  • Avoid vague guesses; use "Unclear; need to inspect X"
  • Cross-reference constantly to maintain global coherence
  • issue-writer - Write up findings after context is built
  • differential-review - Uses context-building for baseline analysis
  • spec-compliance - Compare understood behavior to documentation
