Agent-Guidance-Python: Skill for Claude Code

.agents/skills/agent-guidance/SKILL.md

agent-guidance is a skill for Claude Code, Codex from JunMystery/Agent-Guidance-Python. It costs 30 tokens per session (882 once invoked), scanned A, original, MIT.

A required workflow for checking project standards and retrieving focused codebase context before coding-agent work begins.

In plain words
What is it for?
It helps start coding tasks, search project guidance, read selected files, and inspect project context through dedicated tools. A codebase is the project's source code and related files.
Why use it?
It reduces the chance of ignoring repository conventions and limits unnecessary file reading when gathering project information.

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

This is JunMystery/Agent-Guidance-Python's own configuration. It tells Claude Code and Codex how to work on Agent-Guidance-Python 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 Agent-Guidance-Python 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

agent-guidance 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.

How it starts

The opening of the file, as written. The whole thing — 62 lines — stays where its author put it; the contents beside it link to each section on GitHub.

When to use me

  • Run this skill at the beginning of EVERY task, repository lookup, or codebase refactoring.
  • Run this skill to check project conventions and avoid raw file reading/search operations.

How to use me

You must invoke the agent-guidance-mcp tools in this priority order:

  1. Call agent-guidance-mcp_task_pipeline(task="...") at the start of any coding task to retrieve workspace context, tree, and recommendations.
  2. Call agent-guidance-mcp_guidance(operation="search", query="...") before implementing coding standards.
  3. Call agent-guidance-mcp_project_context(operation="read", relative_path="...") instead of standard file reads (capped at 300 lines).
  4. Call agent-guidance-mcp_project_context(operation="search", query="...") instead of standard file search.

name: agent-guidance description: Core system standards check and token-optimized codebase context retrieval. Run this skill before performing any tool execution or codebase changes.

When to use me

  • Run this skill at the beginning of EVERY task, repository lookup, or codebase refactoring.
  • Run this skill to check project conventions and avoid raw file reading/search operations.
  • Re-run this skill at EACH phase transition (plan → implement → test → review).

How to use me

You must invoke the agent-guidance-mcp tools in this priority order:

  1. Call agent-guidance-mcp_task_pipeline(task="...") at the start of any task or phase to retrieve workspace context, tree, and recommendations.
  2. Call agent-guidance-mcp_guidance(operation="search", query="...") before implementing coding standards.
  3. Call agent-guidance-mcp_project_context(operation="read", relative_path="...") instead of standard file reads (capped at 300 lines).
  4. Call agent-guidance-mcp_project_context(operation="search", query="...") instead of standard file search.

Critical Behavioral Rules

  • When unsure about anything, ASK! DO NOT GUESS.
  • Propose an implementation plan before making any big or complex changes.
  • For each new work phase, re-call agent-guidance-mcp_task_pipeline with the phase goal. Do not carry old context.

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.

agent-guidance is a skill published in the GitHub repository JunMystery/Agent-Guidance-Python (2 stars, last pushed 3mo ago), licensed MIT. It adds 30 tokens to every session and 882 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
