What is synergy-stress-test?

A method for testing whether the claimed benefits of a company deal or partnership are realistic. It separates savings from added revenue, checks the evidence, and reduces optimistic estimates using typical realization rates.

Use it to review synergy estimates, grade support for each benefit, apply evidence-based reductions, check the mechanism behind revenue claims, and assess the adjusted case against a purchase-price hurdle.

It prevents strong cost evidence from making weak revenue claims look credible. It also exposes double counting and avoids producing deal returns when key inputs are missing.

Token cost

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	$0.00058	$0.00845
Opus 5.5	$0.00023	$0.00338
Sonnet 5.5	$0.00012	$0.00169
Haiku 4.5	$0.00006	$0.00085

Security

Grade A, and why

synergy-stress-test 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 2mo 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.

Synergy Stress Test

When to use

Stress-test deal synergies — separate cost vs revenue, grade evidence, apply haircuts, bar-test deal economics. Revenue synergies must not borrow credibility from cost lines.

What this skill does not do

Does not blend cost and revenue lines.
Does not invent deal economics — INPUT NEEDED for price/hurdle.
Does not approve deal — recommendation on adjusted case.
Does not skip mechanism check on revenue.

Preconditions

Input	If missing
Synergy line items	Ask user or deck
Profile synergy haircut / track record	Use default base-rate table; cite source
Purchase price / hurdle for bar test	INPUT NEEDED — no fabricated IRR

Provisional mode

Default haircuts tagged [unverified — industry pattern] unless profile has org track record.

Trust spine

Analytical Rigor (mandatory): Per-line tier, haircut arithmetic, double-count scan.
Per trust-conventions; GATE before board finals.

Base-rate anchor

Type	Typical realization
Cost strong evidence	~70–90%
Cost weak	~40–60%
Revenue any tier	~20–40%

Use profile overrides when configured.

Workflow

Separate every line: cost vs revenue.
Grade evidence per line; state tier, haircut %, adjusted value. Connector-sourced figures (~~bi analytics, ~~crm, ~~spreadsheet) require [sourced: <connector>, <asset>, <as-of>] on each load-bearing number; otherwise use INPUT NEEDED.
Revenue mechanism check — missing mechanism → Weak.
Double-counting scan.
Recompute totals; bar test at adjusted number.

Output format

CONFIDENCE: [...]
COST SYNERGIES: [table]
REVENUE SYNERGIES: [table]
DOUBLE-COUNTING FLAGS: [...]
TOTALS: [...]
DEAL BAR TEST: [...]
RECOMMENDATION: [...]

Worked example

Input: $30M cost synergy (generic 10% G&A) + $50M revenue cross-sell (no mechanism).

Excerpt: Cost weak → ~50% haircut; revenue Weak → ~80% haircut; only works at optimistic number — material finding.

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.
