About this skill

“agystack's agentic engineering framework and rigor mode. Runs poteto-mode playbooks, isolated subagents, and cloud swarms. Use for /agystack, agystack, or rigorous engineering on Antigravity.”

— description from SKILL.md by jtaroreh

agystack Engineering Framework is a skill in jtaroreh/agystack (103 stars). Its SKILL.md is about 322 tokens. Licence: MIT.

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Read skills/poteto-mode/SKILL.md in full, including its Non-negotiables and inline Principles.
  2. Match the task to one of the twenty-three playbooks in skills/poteto-mode/playbooks/.
  3. Follow the Subagent Delegation Invariant. Delegate all non-trivial code edits (> 50 lines, multi-file changes) to poteto-agent via…
  4. Output native Antigravity Artifacts in /brain// (implementation_plan.md, walkthrough.md, _report.md).
  5. Write unslopped prose framed for the consumer and the maintainer.

What it can do on your machine

Read from SKILL.md and the folder at commit d1a0466. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

agystack Engineering Framework loads about 322 tokens when it runs. Until then it costs about 50 tokens; SKILL.md has 94 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~50
When it runs · the whole SKILL.md, loaded when a task matches
~322

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

New task? Playbook match or rigor needed -> apply /agystack or /poteto-mode. Casual turn or user opts out -> don't.

agystack

agystack is an agentic engineering framework for Antigravity, executing under poteto-mode rigor.

When invoked as /agystack, this skill immediately activates the poteto-mode skill (skills/poteto-mode/SKILL.md) and its full playbook engine.

Non-negotiables

  1. Read skills/poteto-mode/SKILL.md in full, including its Non-negotiables and inline Principles.
  2. Match the task to one of the twenty-three playbooks in skills/poteto-mode/playbooks/.
  3. Follow the Subagent Delegation Invariant. Delegate all non-trivial code edits (> 50 lines, multi-file changes) to poteto-agent via invoke_subagent.
  4. Output native Antigravity Artifacts in <appDataDir>/brain/<conversation-id>/ (implementation_plan.md, walkthrough.md, <topic>_report.md).
  5. Write unslopped prose framed for the consumer and the maintainer.
