aod-lens

aod-lens is a skill for Claude Code, Codex from davidmatousek/agentic-oriented-development-kit. It costs 93 tokens per session (857 once invoked), scanned A, a copy of aod-lens, MIT.

A structured-thinking skill that chooses from 14 methods for examining a problem, decision, risk, or system. Methods include asking why a failure happened, testing assumptions, comparing options, and considering side effects.

In plain words
What is it for?
It helps investigate failures, assess risks, challenge plans, prioritize work, compare choices, and understand dependencies or downstream effects.
Why use it?
It gives developers a fitting way to reason through unclear problems instead of relying on an unstructured discussion. The method is selected from the words and context of the request.

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

aod-lens 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.

  1. Route: Match user keywords to lens using table above
  2. Load: Read full methodology from docs/core_principles/[FILE]
  3. Apply: Follow the step-by-step process and use template from that file

If ambiguous, ask:

"Would you like to focus on risks (Pre-Mortem), root cause (5 Whys), or trade-offs (Opportunity Cost)?"

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.
