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 | $0.02248 | $0.02248 |
| Opus 5 | $0.01124 | $0.01124 |
| Sonnet 5 | $0.00450 | $0.00450 |
| Haiku 4.5 | $0.00225 | $0.00225 |
Grade A, and why
claude-code-marketplace 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 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 — 162 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md — Netresearch Claude Code Marketplace
Rules for coding agents editing netresearch/claude-code-marketplace.
They apply to marketplace maintenance only: catalog, landing pages, SEO presentation, cross-linking, and aggregation.
Precedence: rules are additive — scoped files extend this root policy, and on conflict the closest AGENTS.md to the files you're changing wins. See the scope index below.
Do not copy skill-repository quality rules here. Those live in netresearch/skill-repo-skill (skill-repo skill). Do not duplicate runtime instructions from individual SKILL.md files — the marketplace describes how skills are found and presented, not how they execute.
Commands
| Task | Command |
|---|---|
| Validate marketplace.json + README catalog | ./scripts/validate.sh |
| Advisory catalog overlap report (non-blocking) | python3 scripts/overlap-report.py |
Scope separation (mandatory)
| Layer | Responsibility |
|---|---|
| This marketplace repository | Public discovery hub: catalog, categories, landing/install URLs, related skills, SEO-facing copy, internal linking structure. |
| Each skill repository | Source for skill-specific docs: README.md, SKILL.md (runtime behavior), agents/openai.yaml, examples, expected outputs, context requirements, GitHub topics/description. |
SKILL.md in a skill repo |
Runtime behavior for the agent when the skill is loaded. Not the home for marketplace SEO metadata or extended discovery fields in YAML frontmatter. |
Marketplace as canonical discovery hub
- The Netresearch Claude Code Marketplace is the canonical public discovery hub for Netresearch Agent Skills distributed through this plugin.
- Every listed skill must have a stable, publicly understandable presentation (what problem it solves, for whom, how to install).
- The marketplace owns: catalog structure, categories, landing pages, installation paths, cross-links, Related Skills, and SEO-oriented listing copy (titles, summaries, indexable detail pages).
- The marketplace does not define runtime behavior of skills. Execution semantics, triggers, and procedural detail stay in each skill repo’s
SKILL.mdand referenced files.
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.

claude-code-marketplace AGENTS.md is an instructions file published in the GitHub repository netresearch/claude-code-marketplace (55 stars, last pushed 15d ago), licensed MIT. It adds 2,248 tokens to every session, about $0.0112 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.
