AGENTS.md

xhs-imagen AGENTS.md is an instructions file for Codex, OpenCode from NimaChu/xhs-imagen. It costs 283 tokens per session, scanned A, original, MIT.

Repository instructions for xhs-imagen, an agent skill and set of helper scripts for creating and publishing Xiaohongshu content. Xiaohongshu is a social platform where users share image-based posts.

In plain words
What is it for?
Use them when editing the skill, generating Xiaohongshu project prompts, rendering post images, checking image proportions, or changing the image-generation workflow.
Why use it?
They keep the project focused on content creation and publishing while preserving its required image layouts and command-line compatibility. They also list checks that catch invalid project data or rendered images.

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

xhs-imagen AGENTS.md 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.

Repository guidance

This repository contains the xhs-imagen Agent Skill and dependency-free helper scripts.

Required checks

Run before completing a change:

python3 -m unittest discover -s tests -v
python3 scripts/validate_project.py references/project.template.json
python3 scripts/make_prompt_pack.py references/project.template.json --output-dir /tmp/xhs-prompts
python3 scripts/render_xiaohongshu_project.py references/project.template.json --output-dir /tmp/xhs-render --prompts-only

When images were rendered, also run:

python3 scripts/check_png_ratios.py /tmp/xhs-render/images

Editing rules

  • Keep Xiaohongshu creation and publishing needs as the primary product scope.
  • Keep SKILL.md concise and route detail into references/.
  • Preserve the default 3:4 cover and 9:16 inner-page conventions.
  • Prefer an available image-generation tool; use the local renderer only when it is unavailable.
  • Use SVG text patching only after explicit user feedback about a text defect.
  • Keep the legacy free_image_gen.py CLI compatible unless a breaking change is intentional.
  • Do not commit source portraits, credentials, generated watermarks, __pycache__, or unlicensed fonts.
  • Use only Python standard library unless a dependency is clearly justified.

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.
