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 | $0.00045 | $0.00819 |
| Opus 5 | $0.00023 | $0.00409 |
| Sonnet 5 | $0.00009 | $0.00164 |
| Haiku 4.5 | $0.00005 | $0.00082 |
Grade A, and why
engagement-pricing 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 2d 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 — 48 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Engagement Pricing
Develop a commercially credible price that fits the scope, delivery cost, value to the client, and available alternatives. Start with the user's requested pricing decision; preserve an agreed model or terms unless a material problem needs to be raised.
Use the supplied scope, cost basis, capacity, rate card, target margins, budget, and procurement context. Continue a draft with explicit unknowns when inputs are missing; ask only for information that prevents a defensible calculation or recommendation. Do not substitute generic rate or margin benchmarks for firm data.
Select the commercial model
Assess scope certainty, duration, deliverables, dependence on client actions, outcome measurability, attribution, and payment risk. Fixed fees fit bounded deliverables when delivery risk can be estimated. T&M fits evolving work; caps need an explicit scope or effort boundary. Retainers fit continuing access or delivery with defined capacity and service expectations, including a new client when that arrangement is suitable.
Distinguish pricing based on value from payment contingent on outcomes. A fixed value-based fee need not depend on measuring realized results; an outcome-linked fee needs a defensible baseline, measurement rules, attribution, timing, and treatment of external factors. Hybrid structures can share uncertainty without leaving all costs at risk.
Model the economics
Define what each cost includes before adding it. If personnel cost already includes benefits and allocated overhead, do not allocate that overhead again. Separate direct delivery costs, incremental external costs, allocated overhead, and risk contingency. Make the allocation basis explicit. Do not use billing rates as personnel costs.
Calculate the relevant measures with available tools and state their definitions:
- Delivery margin amount = fee minus defined direct delivery cost; percentage = that amount divided by fee.
- Profit after allocations = fee minus all included costs, counted once; percentage = profit divided by fee.
- Minimum fee for target margin
mon that cost basis = included cost /(1-m), form < 1. - Realization = actual fee / rate-card value of actual delivery effort. Explain write-offs, discounts, and scope growth.
- Effective daily rate = fee / total person-days. Confirm the workday length and distinguish headcount from effort.
What ships with it

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.

engagement-pricing is a skill published in the GitHub repository anotb/management-consulting-plugin (52 stars, last pushed 4d ago), licensed MIT. It adds 45 tokens to every session and 819 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 2026-08-30.
