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 | $0.00067 | $0.00846 |
| Opus 5.5 | $0.00027 | $0.00338 |
| Sonnet 5.5 | $0.00013 | $0.00169 |
| Haiku 4.5 | $0.00007 | $0.00085 |
Grade A, and why
forecast scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 71 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Forecast
Project the financial forecast for "$ARGUMENTS". Build a driver-based model that translates planning assumptions into monthly revenue, expense, and cash flow projections.
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
Read .metapowers/finance/<project>/02-plan.md. If this file does not exist, tell the user:
Phase 2 (Plan) has not been completed for "". Run
/finance:plan <project>first, or use--skip-checksto bypass.
Process
-
Read context:
- Read
.metapowers/finance/<project>/01-assess.mdfor baseline data - Read
.metapowers/finance/<project>/02-plan.mdfor assumptions and KPI targets
- Read
-
Build revenue forecast:
- Model each revenue stream separately
- Apply growth assumptions (new customers, churn, expansion, pricing changes)
- Account for seasonality and ramp periods
- Calculate monthly and annual totals
- Reference
${CLAUDE_PLUGIN_ROOT}/shared/financial-model-template.mdfor revenue model structure
-
Build expense forecast:
- Project fixed costs (rent, salaries, subscriptions)
- Project variable costs tied to revenue drivers
- Include planned headcount additions and timing
- Account for one-time costs (equipment, setup, legal)
-
Build cash flow forecast:
- Map revenue to cash collections (considering payment terms)
- Map expenses to cash payments
- Include capital expenditures and financing
- Calculate monthly net cash flow and ending balance
- Determine runway and break-even timing
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.

forecast is a skill published in the GitHub repository bromso/metapowers (2 stars, last pushed yesterday), licensed MIT. It adds 67 tokens to every session and 846 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.
