cognitive_robot_abstract_machine: Skill for Claude Code

.claude/skills/stacked-pr-maintenance/SKILL.md

stacked-pr-maintenance is a skill for Claude Code from cram2/cognitive_robot_abstract_machine. It costs 120 tokens per session (4,017 once invoked), scanned A, original, LGPL-3.0.

A maintenance routine for pull requests whose branches depend on one another. It updates those branches when an earlier pull request is merged and sends approved, unblocked changes to the upstream review queue.

In plain words
What is it for?
Use it to reparent pull requests, restack branches after a parent branch moves, and promote approved branches for review.
Why use it?
It reduces manual work in stacked pull-request workflows, where each change is based on another change and branch relationships can become outdated.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter.

This is cram2/cognitive_robot_abstract_machine's own configuration. It tells Claude Code how to work on cognitive_robot_abstract_machine 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 cognitive_robot_abstract_machine configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is python .claude/stack/maintenance.py board --write.

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

stacked-pr-maintenance scanned grade A 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 11d 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.

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.
