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 | $0.00082 | $0.00786 |
| Opus 5.5 | $0.00033 | $0.00314 |
| Sonnet 5.5 | $0.00016 | $0.00157 |
| Haiku 4.5 | $0.00008 | $0.00079 |
Grade A, and why
assess scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 66 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Assess
Consolidate and validate financial data for "$ARGUMENTS". Gather historical financials, verify data integrity, and establish the baseline from which all planning begins.
Arguments. $ARGUMENTS may contain the project name and optional flags. Take the first token as <project> and treat --skip-checks as a flag; never include flags in file paths. All paths below use <project>. If --skip-checks is present, skip the prerequisite check and, before writing any artifact, append one line to .metapowers/finance/<project>/skip-log.md: - <ISO timestamp> — <skill name> skipped prerequisite check for <artifact file> — reason: <reason or "none given">.
Compute with code. Perform every calculation (totals, balances, ratios, variances, projections) with a script — Bash, Python or a spreadsheet formula written to a file — and include the computation alongside the result. Never do arithmetic mentally.
Prerequisites
None — this is the first phase.
Process
-
Ask financial data questions:
- What type of business is this? (SaaS, e-commerce, services, marketplace, hardware)
- What stage? (pre-revenue, early-stage, growth, mature)
- What financial data is available? (P&L, balance sheet, cash flow, bank statements)
- What period does the data cover?
- What accounting method? (cash vs accrual)
- What currency and fiscal year?
-
Consolidate data sources:
- List all revenue streams and categorize them
- List all cost categories (fixed, variable, one-time)
- Identify the chart of accounts or cost centers
- Note any data gaps or inconsistencies
-
Validate and reconcile:
- Cross-check revenue against bank deposits or invoices
- Verify expense categories are consistent across periods
- Flag any anomalies, one-time items, or restatements
- Calculate basic trends (MoM, YoY growth rates)
-
Establish baseline metrics:
- Monthly Recurring Revenue (MRR) or equivalent
- Gross margin
- Burn rate and runway
- Headcount and revenue per employee
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.

assess is a skill published in the GitHub repository bromso/metapowers (2 stars, last pushed yesterday), licensed MIT. It adds 82 tokens to every session and 786 once invoked, about $0.0003 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 2026-10-21.
