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 | $0.00012 | $0.00187 |
| Opus 5 | $0.00006 | $0.00093 |
| Sonnet 5 | $0.00002 | $0.00037 |
| Haiku 4.5 | $0.00001 | $0.00019 |
Grade A, and why
prompt 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 8d 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
Prompt Synthesizer
Create a complete prompt by combining:
- The next.md template from ~/.claude/commands/next.md
- User's task: $ARGUMENTS
Task
- Read next.md command file
- Replace
$ARGUMENTSplaceholder with the actual task - Output the complete prompt in a code block
Output Format
[Complete synthesized prompt ready to copy]
Synthesis Guidelines
- Preserve the workflow and requirements from next.md
- If task mentions specific languages, emphasize those sections
- For complex tasks, highlight "ultrathink" and "multiple agents"
- For refactoring, emphasize "delete old code" requirements
- Keep all critical requirements (hooks, linting, testing)
Begin synthesis now.
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 is a command published in the GitHub repository joshsymonds/nix-config (836 stars, last pushed yesterday), licensed MIT. It adds 12 tokens to every session and 187 once invoked, about $0.0001 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.
