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 | $0.00049 | $0.00747 |
| Opus 5 | $0.00024 | $0.00374 |
| Sonnet 5 | $0.00010 | $0.00149 |
| Haiku 4.5 | $0.00005 | $0.00075 |
Grade A, and why
break-even-analysis 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.

Break Even Analysis
Use this skill to run Break Even Analysis as a practical consulting method, not as a generic framework explanation.
Method Notes
- Separate fixed cost, variable cost, unit economics, and time horizon.
- State the exact threshold that makes the option viable.
Required Inputs
Collect or infer these inputs before execution:
- fixed costs
- variable costs
- price or benefit per unit
- time horizon
- constraints
If an input is missing, do not block automatically. Mark it as missing, state the assumption used, and add a validation action.
When Not To Use
Do not use when fixed costs, variable costs, unit revenue, and the relevant time horizon cannot be estimated. Break-even analysis tests an economic threshold; it does not establish overall strategic fit.
Adjacent Methods
cost-benefit-analysis: compare broader benefits, costs, timing, and risk.pricing-strategy-check: test price metric, willingness to pay, margin, and discount risk.
Step-by-Step Execution
| Step | Required input | How to execute | Output |
|---|---|---|---|
| Define break-even unit | Decision, economics, unit of value. | Choose unit, revenue, margin, savings, or time as the threshold. | Break-even definition. |
| Separate cost types | Fixed cost, variable cost, recurring cost, one-off cost. | Classify costs so the formula is clear. | Cost structure. |
| Estimate unit economics | Price, margin, savings, utilization, adoption. | Calculate contribution or benefit per unit. | Unit economics. |
| Calculate threshold | Cost structure and unit economics. | Compute break-even quantity, revenue, savings, or months. | Break-even threshold. |
| Test realism | Market size, capacity, adoption, timeline. | Assess whether reaching the threshold is plausible. | Viability interpretation. |

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.

break-even-analysis is a skill published in the GitHub repository fzfclee/consulting-skills (4 stars, last pushed 21d ago), licensed Apache-2.0. It adds 49 tokens to every session and 747 once invoked, about $0.0002 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 2026-08-31.
