Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00030 | $0.00882 |
| Opus 5 | $0.00015 | $0.00441 |
| Sonnet 5 | $0.00006 | $0.00176 |
| Haiku 4.5 | $0.00003 | $0.00088 |
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 3d 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:
- Call
agent-guidance-mcp_task_pipeline(task="...")at the start of any coding task to retrieve workspace context, tree, and recommendations. - Call
agent-guidance-mcp_guidance(operation="search", query="...")before implementing coding standards. - Call
agent-guidance-mcp_project_context(operation="read", relative_path="...")instead of standard file reads (capped at 300 lines). - 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:
- Call
agent-guidance-mcp_task_pipeline(task="...")at the start of any task or phase to retrieve workspace context, tree, and recommendations. - Call
agent-guidance-mcp_guidance(operation="search", query="...")before implementing coding standards. - Call
agent-guidance-mcp_project_context(operation="read", relative_path="...")instead of standard file reads (capped at 300 lines). - 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_pipelinewith the phase goal. Do not carry old context.
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.

agent-guidance is a skill published in the GitHub repository JunMystery/Agent-Guidance-Python (2 stars, last pushed 1mo ago), licensed MIT. It adds 30 tokens to every session and 882 once invoked, about $0.0002 per session on Opus 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.
