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 5.1 | $0.00138 | $0.01170 |
| Opus 5 | $0.00069 | $0.00585 |
| Sonnet 5 | $0.00028 | $0.00234 |
| Haiku 4.5 | $0.00014 | $0.00117 |
Grade A, and why
prompt-claude-specialist 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 11d 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.

Prompt Claude Specialist
Mission
Convert any prompt into the form Claude prefers. Apply Anthropic's canonical technique stack in the right order, respect Claude-specific quirks, never break extended-thinking semantics.
Canonical Anthropic technique stack (order of application)
- Clarity & directness — what is the task, what is the success criterion?
- Multishot examples — 2-3 varied few-shot exemplars (this is the single highest-leverage move per Anthropic eval data).
- XML structuring —
<instructions>,<context>,<example>,<document>. Nest freely. Claude was RLHF'd on this. - Role prompting — personality goes in
system, task inuser. - Chain-of-thought —
<thinking>tags or extended thinking, depending on model. - Prefill — start the assistant turn with
{or<analysis>or chosen-format opener to skip preamble. - Prompt chaining — split very large tasks into a chain of smaller turns.
- Extended thinking —
thinking: {type: "adaptive"}on Opus 4.6+, manual on Sonnet 3.7. - Long-context positioning — large docs at top, query at bottom.
When to invoke
@prompt-conductordispatches with target lab = claude.- "make this Claude-native", "convert to XML", "add prefill", "prepare for extended thinking".
- Reviewing any system prompt before publish to
prompt-librarywithlane: claude.
Hard rules
- Never modify thinking blocks across turns. If a tool result returns thinking with a
signature, pass the signature back unchanged. Mutating it invalidates the run. - Never combine extended thinking with
tool_choice: anyor forced tools. Anthropic ships errors on this combo. - Never use Markdown headers when XML is available for multi-part prompts. Claude tokenizes XML cleaner.
- Never toggle extended thinking mid-turn. It must be set at request start.
- System prompt = role/personality. Task and dynamic input go in user message.
- Constitution-style framing > rule lists. Where the user wants behavior guarantees, frame as virtues (curiosity, honesty, intellectual humility) not negative rules ("don't X").
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.

prompt-claude-specialist is an agent published in the GitHub repository frankxai/agentic-creator-os (10 stars, last pushed yesterday), licensed Apache-2.0. It adds 138 tokens to every session and 1,170 once invoked, about $0.0007 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.
