.claude/skills/ae-proof-agent/SKILL.md

ae-proof-agent is a skill for Claude Code, Codex from aegntic/cldcde. It costs 85 tokens per session (350 once invoked), scanned A, original, MIT.

A research and decision framework for the ae.ltd proof-agent concept, covering product analysis, technical architecture, competitor comparison, red-team review, and build-versus-buy decisions. Red-team review means deliberately looking for weaknesses and failure modes.

In plain words
What is it for?
Creating or reviewing PRDs, technical specifications, competitive diligence, leadership memos, and risk-focused product assessments.
Why use it?
It gives technical and product decisions a documented process that separates verified facts, inferences, and unknowns.

This is aegntic/cldcde's own configuration. It tells Claude Code and Codex how to work on cldcde itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything cldcde configures →

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

ae-proof-agent 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 1mo 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.

What it actually says

ae-proof-agent

Read references/RESEARCH-GUARDRAILS.md first.

Then use the bundle in this order:

  1. Read references/COMPETITIVE-DILIGENCE.md.
  2. Use references/PRD.md and references/TECHSPEC.md as the base spec.
  3. Run the prompt chain in prompts/ when generating comparable multi-agent outputs.
  4. Score outputs with templates/SCORECARD.md.
  5. Assemble the final memo with templates/FINAL-REPORT-OUTLINE.md.

Rules:

  • Separate Verified, Inference, and Unknown.
  • Do not invent backend details, customer metrics, or infra choices.
  • Use exact dates for recent releases and product changes.
  • Prefer primary sources when browsing is required.
  • Optimize for decision quality, not volume.

Use the prompt chain like this:

  • prompts/01-DISCOVERY.md for a source-grounded brief
  • prompts/02-PRD.md for product requirements
  • prompts/03-TECHSPEC.md for implementation planning
  • prompts/04-REDTEAM.md for failure analysis
  • prompts/05-SYNTHESIS.md for the final leadership memo
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.
