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.

What it costs to keep this loaded
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 | $0.00080 | $0.02430 |
| Opus 5 | $0.00040 | $0.01215 |
| Sonnet 5 | $0.00016 | $0.00486 |
| Haiku 4.5 | $0.00008 | $0.00243 |
Grade A, and why
growth-accounting 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 9d 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 — 123 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Growth Accounting
Reconcile how a defined customer or value base moved from one period to the next. Freeze entity, eligibility, identity, period, maturity, and value basis before classifying movement; a balanced bridge describes what changed, not why it changed or who caused it.
Read accounting-contract.md before accepting inputs. Read classification-and-equations.md before assigning movement classes or calculating a bridge. Read diagnosis-and-interpretation.md before interpreting mix, quality, concentration, or possible constraints. Read governance-and-boundaries.md before using personal data, transferring a method across markets, routing specialist work, or preparing external actions. Read output-contract.md before delivery. Use playbook-sources.md for the pinned Growth Playbook basis.
Select One Mode
| Mode | Use |
|---|---|
reconcile |
Build a reproducible entity, activity, or recurring-value bridge from supplied compatible evidence |
diagnose |
Audit definitions, classifications, reconciliation, mix, and movement quality and identify the smallest unresolved evidence |
portfolio |
Compare and reconcile compatible bridges across products, cohorts, segments, markets, periods, or value bases |
Name one primary mode, decision, owner, entity and level, active or value state, opening and closing periods, observation and maturity windows, product, segment, cohort, market, value basis, currency, as-of date, source versions, review date, and external-action boundary. Public sources can verify visible products, prices, releases, and historical public events. They cannot establish private active populations, movement classes, retention, revenue, contribution, cash, attribution, or causes.

What ships with it
6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

growth-accounting is a skill published in the GitHub repository krillinai/growth-skills (43 stars, last pushed 16d ago), licensed MIT. It adds 80 tokens to every session and 2,430 once invoked, about $0.0004 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 2026-09-03.
