.agents/skills/gf-agent-maintenance/SKILL.md

gf-agent-maintenance is a skill for Claude Code, Codex from brucemcpherson/gas-fakes. It costs 0 tokens per session (339 once invoked), scanned A, original, MIT.

A maintenance workflow for a Google Apps Script automation agent and its supporting test project. It keeps the agent's skills, index, documentation, and downloadable package aligned with the code.

In plain words
What is it for?
Use it to rebuild the agent's knowledge files, extract patterns from tests, check documentation, and package updates.
Why use it?
It reduces drift between implemented behavior, tests, documentation, and the agent's published files.

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

This is brucemcpherson/gas-fakes's own configuration. It tells Claude Code and Codex how to work on gas-fakes 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 gas-fakes 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

gf-agent-maintenance 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 10d 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.

What it actually says

Skill: gf-agent-maintenance

Overview

This skill is used to maintain and update the gf_agent (Google Apps Script Local Automation Agent). It ensures the agent's internal skills, index, and documentation stay synchronized with the latest implementations in gas-fakes.

Responsibilities

  1. Synchronize Skills: Run node gf_agent/scripts/builder.js whenever progress/ files are updated to refresh the agent's knowledge base.
  2. Update Documentation: Analyze new test files in test/ to extract usage patterns and add them to gf_agent/documentation.md.
  3. Verify Agent: Ensure gf_agent/SKILL.md and gf_agent/README.md accurately reflect the current capabilities of the project.
  4. Package for Distribution: Ensure the gf_agent/ directory is self-contained and ready for download by users.

Workflow

  1. Detect Changes: Monitor progress/ and test/ for updates.
  2. Local Model Consultation: Delegate log analysis, pattern extraction from tests, and drafts of documentation updates (gf_agent/documentation.md, etc.) to the local model via the omlx/query_local_model tool.
  3. Run Builder: Execute the build script to regenerate markdown files.
  4. Refine Patterns: If a new service or complex pattern is added to test/, document it in gf_agent/documentation.md using the local model's extracted patterns.
  5. Test/Verify the Agent: Use the local model to simulate user requests, verify code generation, and ensure the agent performs as expected.
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.
