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.

Security

Grade A, and why

evp-brief 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.

EVP Brief — sub-skill

Produces a structured 3-tier EVP brief covering the three tiers where most B2B buyers live: Tier 2 (problem-aware), Tier 3 (solution-aware), Tier 4 (product-aware).

Activation

Loaded by evp on:

  • "Build an EVP brief"
  • "3-tier brief"
  • "EVP across awareness levels"

Workflow

1. Confirm the ICP scope

The brief is per-ICP. If the user has multiple ICPs, ask: "Which ICP are we building this brief for? (Run again per segment.)"

2. Capture inputs once

Input Source
icp Specific ICP segment
psp PSP doc from claude-psp (or build inline)
outcome The specific result you deliver
tradeoff The obvious tradeoff you spare them
competitors (optional) Top 2-3 competitors for Tier 4 framing
proof_per_tier (optional) Case study / metric per tier

3. Generate the brief

For each of Tier 2, Tier 3, Tier 4:

  • Audience description (what they know, what they don't)
  • Tier-appropriate pain framing
  • 1 primary EVP (best variant) + 1 alternate
  • Proof aligned to that tier (different proofs land at different tiers)
  • Where to deploy this EVP (which surfaces)

4. Output

# EVP Brief — <ICP>

**PSP anchor:** <pain in their vocabulary, one sentence>

---

## Tier 2 — Problem-aware

**Audience knows:** the pain exists; doesn't know solutions exist (or
doesn't think any are worth evaluating yet).

**Best framing:** Pain reveal + reframe.

### Primary EVP
"<22-word line>"

### Alternate
"<22-word line>"

### Proof for this tier
<Demonstration of the pain at scale — e.g., "62% of Series-B SaaS hit
this within 18 months of funding.">

### Deploy on
- Hero copy on landing pages
- Top-of-funnel ad creative
- Cold email line 3 (when targeting based on signal that implies awareness)
- Podcast-appearance pitch lines

---

## Tier 3 — Solution-aware

**Audience knows:** solutions exist; comparing categories of approach
(in-house vs agency vs DIY vs tool).

**Best framing:** Category split — why your category beats the
traditional one.

### Primary EVP
"<22-word line>"

### Alternate
"<22-word line>"

### Proof for this tier
<Comparison: outcome metric of your category vs traditional approach —
e.g., "Targeted outbound: $640 CPM. Generic agency: $2,800 CPM.">

### Deploy on
- Comparison pages
- Mid-funnel ads
- Cold email line 3 (when targeting based on category-discontent signal)
- Sales call opener (when prospect has tried alternatives)

---

## Tier 4 — Product-aware

**Audience knows:** specific vendors exist; comparing options head to head.

**Best framing:** Vendor delta — your specific advantage on a specific
axis vs named competitor.

### Primary EVP
"<22-word line — references competitor>"

### Alternate
"<22-word line — references competitor>"

### Proof for this tier
<Specific competitor delta — e.g., "Versus <competitor>, we ship the
<feature> in <timeframe> instead of <their timeframe>.">

### Deploy on
- Pricing page hero
- Sales-call objection handling
- Battlecards
- Bottom-funnel ads

---

## The single source of truth

This brief is the authoritative messaging document for <ICP>. When
hero copy, ad creative, cold email, or pricing-page lines need to be
written or rewritten, pull from the tier that matches the audience's
actual awareness level.

Re-run this brief every 90 days. EVPs decay as the market catches up
and competitor positioning shifts.

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.
