git-aware-coding-agent: Skill for Cursor

.cursor/skills/avos-history/SKILL.md

avos-history is a skill for Cursor from Avos-Lab/git-aware-coding-agent. It costs 10 tokens per session (683 once invoked), scanned A, original, Apache-2.0.

A repository-history lookup for understanding how a codebase or feature changed over time. It presents earlier pull requests, issues, commits, and the reasons behind them in chronological order.

In plain words
What is it for?
Use it to investigate the history of a module, feature, file, or behavior before refactoring or changing it.
Why use it?
It helps prevent changes that overlook past decisions or constraints. This matters when modifying existing, shared, or unfamiliar production code.

Skill for Cursor

This is Avos-Lab/git-aware-coding-agent's own configuration. It tells Cursor how to work on git-aware-coding-agent 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 git-aware-coding-agent 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

avos-history 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.

Avos History

Use this skill when you need chronological history of a subject in the repository.

When to Use

Use this skill when at least one trigger applies:

  • You are changing existing production behavior
  • You are refactoring or touching shared/unfamiliar modules
  • The change is medium/large (multi-file, broad behavior impact)
  • You need to understand prior constraints before redesigning logic

You can skip for low-risk tasks:

  • Docs/comments/typo-only edits
  • New isolated files with no modification to existing behavior
  • Test-only updates not affecting runtime behavior

Command

avos history --json "subject or topic"

Examples

Module History

avos history --json "authentication module"

Feature Evolution

avos history --json "user registration flow"

File History

avos history --json "database connection handling"

    },
    "summary": {
      "text": "No engineering history found for \"subject\"."
    }
  }
}

Best Practices

  1. Check history before modifying: Always understand the context before changing existing code
  2. Use specific subjects: "payment processing" is better than "payments"
  3. Review the timeline: Understand the evolution before making 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.
