aef-assistant

aef-assistant is a skill for Claude Code, Codex from DimitriGeelen/agentic-engineering-framework. It costs 59 tokens per session (636 once invoked), scanned C, original, Apache-2.0.

A guide for using the Agentic Engineering Framework, a set of rules and tools for controlling software tasks, decisions, memory, and subagents. It describes required task states, approval gates, and architecture-exploration workflows.

In plain words
What is it for?
It is for starting and focusing tasks, recording architecture questions, handling human approvals, controlling destructive actions, and working with subagents.
Why use it?
It helps agents follow the repository's governance rules before changing code, committing work, or running risky commands.

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 C, and why

aef-assistant scanned grade C with 1 finding 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 today.

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.

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

- Destructive commands (`rm -rf`, `git reset --hard`, `git push --force`, `--no-verify`) are gated at Tier 0.

Agentic Engineering Framework (AEF) Antigravity Skill

This skill teaches Antigravity / OpenGravity (AGY) agents and subagents how to navigate and operate within an AEF-governed repository.

Core Directives & Invariants

  1. P-002: Task-First Structural Enforcement

    • No source code or configuration modifications without an active task in started-work state.
    • Run bin/fw work-on "<task name>" --type build or bin/fw work-on T-XXX to establish focus.
    • Every git commit MUST reference a task ID: git commit -m "T-XXX: <summary>".
  2. Tier 0 Protection & Human Sovereignty

    • Destructive commands (rm -rf, git reset --hard, git push --force, --no-verify) are gated at Tier 0.
    • Never attempt to approve your own work. Ask the human operator to run bin/fw tier0 approve or record decisions.
  3. Inceptions & Architecture Exploration

    • Use bin/fw inception start "<name>" for architecture, spikes, or strategic decisions.
    • Declare open questions (- **IW-N: <question>**) with confidence ratings (0-3).
    • Inceptions end in a human decision (bin/fw inception decide T-XXX go|no-go|defer).
  4. Component Fabric & Dependency Tracking

    • View fabric graph: bin/fw fabric overview
    • Check architectural drift: bin/fw fabric drift
    • Register components: bin/fw fabric register
  5. Subagent Delegation & Concurrency

    • When spawning subagents via invoke_subagent, always pass the current Task ID (T-XXX) in the initial prompt so the subagent operates within the task boundary.
    • Use branch workspaces for isolated experiments and share workspaces for read-heavy investigations.
  6. TermLink Cross-Terminal & Multi-Agent Mesh

    • Check status: termlink list --json
    • Interact with workers: termlink interact <session> "<command>" --json
    • Send PTY inputs: termlink pty inject <session> "<prompt>" --enter
    • Post results to AEF Bus: bin/fw bus post --task T-XXX --agent antigravity --summary "<summary>"

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.

aef-assistant is a skill published in the GitHub repository DimitriGeelen/agentic-engineering-framework (13 stars, last pushed today), licensed Apache-2.0. It adds 59 tokens to every session and 636 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it C with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-04.
