context-use-old: Skill for Claude Code

.agents/skills/maintain-knowledge-template/SKILL.md

maintain-knowledge-template is a skill for Claude Code, Codex from massimoalbarello/context-use-old. It costs 67 tokens per session (765 once invoked), scanned A, original, MIT.

A maintenance workflow for editing a repository's default knowledge-base template without changing its meaning. It covers AGENTS.md guides, managed instructions, bootstrap metadata, automation guidance, and regression tests.

In plain words
What is it for?
Use it when changing default knowledge templates, moving guidance to the correct file, updating automation instructions, or maintaining the tests that protect those rules.
Why use it?
It prevents the same rule from being copied into several places with conflicting wording or ownership. It also helps preserve behavior while improving the documentation structure.

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents); mentions AGENTS.md.

This is massimoalbarello/context-use-old's own configuration. It tells Claude Code and Codex how to work on context-use-old 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 context-use-old 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

maintain-knowledge-template 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 2mo 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.

Maintain Knowledge Template

Keep each rule in one authoritative layer and preserve behavior while improving clarity.

1. Establish the current contract

Start from the latest remote default branch and inspect the complete affected guidance chain, metadata and template tests. Read recent history when wording may encode a regression fix.

Record the behaviors that must survive from the authoritative guides, managed instructions, tests and history. Treat that as an edit-specific inventory; do not restate their rules here.

2. Assign one owner to every rule

Use this ownership model:

  • Root AGENTS.md: invariants that apply to every knowledge write.
  • Entity or subtree AGENTS.md: subject boundary, paths, local page responsibilities, timeline eligibility and genuine exceptions within that subtree.
  • automations/AGENTS.md: conventions for creating and maintaining automations.
  • Automation instructions: ordered input, processing, checkpoint, failure and reporting workflow only.
  • Tool descriptions: argument and response semantics already enforced by the tool surface.
  • Tests: semantic ownership and required behavior, not preferred prose.

Move a misplaced rule to its owner and replace copies with a link or a short instruction to apply that guide. Do not leave two normative versions behind.

3. Make workflows executable

For automation edits, read the complete automations/AGENTS.md and the target instructions. The guide owns shared authoring conventions; each instructions page owns its job-specific transitions. Verify that the resulting workflow is executable without copying either contract into this skill.

4. Protect information density

Treat every edit as a refactor, not an append. Do not simply add a rule to an AGENTS.md or automation instruction. First make the complete affected text as clear and concise as possible without losing behavior: remove duplication, replace or tighten overlapping prose, and move rules to their owner. Add net-new text only for a genuinely missing behavior or safeguard.

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.
