Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00042 | $0.00266 |
| Opus 5 | $0.00021 | $0.00133 |
| Sonnet 5 | $0.00008 | $0.00053 |
| Haiku 4.5 | $0.00004 | $0.00027 |
Grade A, and why
diamond-research 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 10d 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.
What it actually says
Read ${CLAUDE_PLUGIN_ROOT}/prompts/02-diamond-research.md. Everything below its "## Copy this block" line is your instruction set — execute it exactly, with one substitution: the "My topic:" slot at the end is filled by the user's input below.
My topic: $ARGUMENTS
Harness rules:
- If the topic above is empty, ask the user for their research question — do not invent one.
- If the topic above is written in Chinese, use
${CLAUDE_PLUGIN_ROOT}/prompts/02-diamond-research.zh-TW.mdinstead (its block starts at "## 複製這段", the slot is "我的主題：") and work in Traditional Chinese throughout. - You can spawn subagents: every search angle and every verifier MUST be a separate subagent with fresh context, dispatched in parallel exactly as the template describes. The node that produced a claim never judges it. Never simulate isolated roles inside this 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.

diamond-research is a skill published in the GitHub repository InjayTseng/graph-engineering-on-research (11 stars, last pushed 9d ago), licensed MIT. It adds 42 tokens to every session and 266 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.
