What is ai-sync AGENTS.md?

Repository instructions for XyrusCode/ai-sync, covering global agent rules and required development practices.

Use them when working in XyrusCode/ai-sync, especially for managing long tasks and preparing reviewed changes.

They prevent context loss during long sessions and require changes to go through a branch and pull request instead of being committed directly to the main branch.

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.

Model	Per session	Once invoked
Fable 5.1	$0.01012	$0.01012
Opus 5.5	$0.00405	$0.00405
Sonnet 5.5	$0.00202	$0.00202
Haiku 4.5	$0.00101	$0.00101

Security

Grade B, and why

ai-sync AGENTS.md scanned grade B with 1 finding 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 27d 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.

Enumerates other installed skillsmediumAgent snooping

Other skills' SKILL.md files reveal prompts, capabilities and secrets that should be invisible to peers.

- Before hand-rolling complex multi-step routines, inspect available skills using `skills list` or `skills find <query>`.

The opening of the file, as written. The whole thing — 81 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS — Global instructions and critical rules

PR/MR Creation — CLI Auto-Detection

When creating a pull request or merge request, detect the remote and use the appropriate CLI:

GitHub (github.com) → Use gh pr create
Azure DevOps (dev.azure.com or *.visualstudio.com) → Use az repos pr create
GitLab (gitlab.com or self-hosted) → Use gl mr create

Implementation:

Check the repo remote with git remote get-url origin
Route to the appropriate CLI based on domain
If CLI is not installed, assist with manual creation via web UI
Assume CLIs are installed; they are standard on this machine

Critical Rules

Prevent context rot: When a session grows heavy (many turns, many files, re-deriving state), split the work into a fresh, nested context before output quality degrades. Use a native nested-session primitive if available; otherwise emit a self-contained handoff prompt. Checkpoint before splitting. See docs/context-rot.md for full procedure and templates.
Never commit directly to main. Always create a branch and open a Pull Request for review and CI before merging. This repository enforces review-first changes.

Tool Usage & Ecosystem Guidelines

All agent harnesses have access to the following shared tools and services. Use them when applicable:

Graphify (Codebase Knowledge Graph)

Knowledge graph engine and MCP service (graphify-mcp) at graphify-out/ mapping god nodes, communities, and cross-file dependencies.

Rules:

For codebase questions, first run graphify query "<question>" when graphify-out/graph.json exists. Use graphify path "<A>" "<B>" for relationships and graphify explain "<concept>" for focused concepts.
If graphify-out/wiki/index.md exists, use it for broad navigation instead of raw source browsing.
After modifying code, run graphify update . to keep the graph current (AST-only, no API cost).

Ponytail (Lazy Senior Dev Mode)

Before writing any code, stop at the first rung that holds:

Does this need to be built at all? (YAGNI)
Does it already exist in this codebase? Reuse existing helpers/patterns, do not rewrite.
Does the standard library already do this? Use it.
Does a native platform feature cover it? Use it.
Does an already-installed dependency solve it? Use it.
Can this be one line? Make it one line.
Only then: write the minimum code that works.

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.

ai-sync AGENTS.md is an instructions file published in the GitHub repository XyrusCode/ai-sync (2 stars, last pushed 2d ago), licensed MIT. It adds 1,012 tokens to every session, about $0.0040 per session on Opus 5.5. A static security scan graded it B with 1 finding (enumerates other installed skills). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.

Working notes and architecture documentation for the new esbuild-based build system in build/next. Use when making changes to the new build pipeline (transpile/bundle commands, NLS plugin, source-map handling, resource copying, or self-hosting watch tasks).
