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 | $0.00017 | $0.00962 |
| Opus 5.5 | $0.00007 | $0.00385 |
| Sonnet 5.5 | $0.00003 | $0.00192 |
| Haiku 4.5 | $0.00002 | $0.00096 |
Grade A, and why
brrrr 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 1mo 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 — 146 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Instructions
When this command is invoked, analyze a BRRRR investment opportunity:
1. Load Reference Material
Read the property types reference for residential guidance:
the references/property-types.md file from the real-estate-investment skill in this plugin
2. Collect BRRRR Inputs
Use AskUserQuestion to gather:
Purchase Phase:
- Purchase price
- Purchase closing costs (default: 2-3% of price)
- Initial loan terms (if financing): down payment %, interest rate, term
Rehab Phase:
- Estimated rehab cost (itemized or total)
- Rehab timeline (months)
- Holding costs during rehab: loan payments, utilities, taxes, insurance
ARV (After Repair Value):
- After-repair value estimate (from comps)
- Source of ARV (appraisal, Zillow, agent CMA)
Rent Phase:
- Expected monthly rent after rehab
- Vacancy rate assumption (default: 8%)
- Operating expenses (% of gross rent or itemized)
Refinance Phase:
- Refinance loan-to-value (LTV) ratio (typical: 75-80% of ARV)
- Refinance interest rate and term
- Refinance closing costs (default: 2-3% of new loan)
3. Calculate Total Investment
Compute all-in cash investment:
Total Investment = Purchase Price
+ Purchase Closing Costs
+ Down Payment (if financed)
+ Rehab Cost
+ Holding Costs
- Initial Loan Amount (if applicable)
4. Validate with Rules of Thumb
Check against BRRRR rules and flag pass/fail:
70% Rule:
- Formula:
Purchase Price + Rehab ≤ 70% × ARV - Pass/Fail indicator
- Margin of safety
1% Rule:
- Formula:
Monthly Rent ≥ 1% × Total Investment - Pass/Fail indicator
- Actual percentage achieved
2% Rule (Aggressive):
- Formula:
Monthly Rent ≥ 2% × Purchase Price - Pass/Fail indicator
5. Analyze Cash Flow After Refinance
Calculate post-refinance operating performance:
- New loan amount:
ARV × Refinance LTV - Monthly debt service on new loan
- Monthly cash flow:
(Monthly Rent × (1 - Vacancy Rate)) - Operating Expenses - Debt Service - Annual cash-on-cash return on remaining equity
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.
- 1mo ago First seen · 146 lines · 17 tokens per session scan A 7a9e7a279c1a
brrrr is a command published in the GitHub repository Aznatkoiny/zAI-Skills (10 stars, last pushed 2mo ago), licensed MIT. It adds 17 tokens to every session and 962 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-09-03.
Other commands, from other repositories
orchestrate
Do this task as an orchestrator. The aim is the same result at a fraction of the cost: in a long session, every token in this conversation is re-read on each later request, while a subagent's reading is discarded when it returns. The plugin's subagents run on Haiku 5.5, about 40× cheaper per token than Opus 5.5.
conjure-agent
Creates or updates a Claude Code agent definition (/.claude/agents/ .md or project-local).
conjure
Use when you want to build a new Claude Code skill, agent, hook, or MCP server but aren't sure which — or when you want to describe what you want in plain language. Auto-detects the right artifact type, asks targeted questions, explains the reasoning, then builds it.
conjure-mcp
Create a Claude Code MCP (Model Context Protocol) server. Provide a description of what external system or data source you want Claude to connect to.
conjure-help
Show help for the conjure toolkit — all commands, argument syntax, update modes, and decision guide. Use when you want to know which conjure command to use or how any conjure command works.
strip
This is the task-based stripper, not the always-on prior: a deliberate cleanup pass you asked for. Apply the fp-minify doctrine to the target and remove or compress comments that don't earn their place.
