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 | $0.00076 | $0.03448 |
| Opus 5 | $0.00038 | $0.01724 |
| Sonnet 5 | $0.00015 | $0.00690 |
| Haiku 4.5 | $0.00008 | $0.00345 |
Grade A, and why
conventions 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 4d 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 — 222 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Universal NL Programming Conventions
The cross-tool floor for all artifact schemas. Use this skill when scoring or writing any NL programming artifact regardless of which tool (Claude Code / Codex CLI / Antigravity) it targets.
Tool-specific overlays load on top of this universal floor:
nlpm:conventions-claude— Claude Code artifacts (.claude/,plugin.json, etc.)nlpm:conventions-codex— Codex CLI artifacts (.codex/,.agents/,AGENTS.md)nlpm:conventions-antigravity— Antigravity (and legacy Gemini CLI) artifacts (.gemini/,.agent/)
The scorer loads the matching overlay per tier classification — see agents/scorer.md step 3.
Design rationale: analysis/multi-tool-design-2026-05.md.
1. SKILL.md — Cross-Tool Open Standard
SKILL.md is the Agent Skills open spec, stewarded by the Agentic AI Foundation under the Linux Foundation. Anthropic published the spec on 2025-12-18; OpenAI, Microsoft, Google adopted within 48 hours. By 2026-03, 32+ tools read the same SKILL.md format (Claude Code, Codex, Gemini CLI / Antigravity, Cursor, Kiro, Continue, etc.).
Authoritative reference: https://agentskills.io/specification
Required frontmatter (per the open spec):
name— string; 1-64 chars, lowercase + hyphens only, MUST match parent directory name (no leading/trailing/consecutive hyphens).description— string; 1-1024 chars; should describe what the skill does AND when to use it.
Optional frontmatter (per the open spec):
license— license name or reference to a bundled file.compatibility— environment requirements, max 500 chars (e.g., "Designed for Claude Code", "Requires Python 3.14+ and uv").metadata— arbitrary key-value mapping (author,version, etc. go here, NOT as top-level fields).allowed-tools— space-separated tool list (experimental in spec; tool-specific in practice — e.g.,Bash(git:*) Read).
Tool-specific extensions to SKILL.md frontmatter live in the per-tool overlay skills. The scorer applies the universal spec rules to ALL SKILL.md files. Tool-specific overlay rules apply ONLY to files at the matching tool's canonical paths.
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.

conventions is a skill published in the GitHub repository xiaolai/nlpm (134 stars, last pushed today), licensed ISC. It adds 76 tokens to every session and 3,448 once invoked, about $0.0004 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 2026-08-30.
