claude-evp: Instructions file for Claude Code

AGENTS.md

claude-evp AGENTS.md is an instructions file for Claude Code, Codex, OpenCode from cmj-hub/claude-evp. It costs 762 tokens per session, scanned A, original, MIT.

Instructions for an agent that writes short value propositions, or brief statements of what a business offers and for whom. It requires brand settings and a writing guide before producing those statements.

In plain words
What is it for?
They are for onboarding the agent, checking a message against the brand and audience, and creating evidence-based value propositions within the specified word limit.
Why use it?
They prevent vague claims, invented proof, incorrect audience targeting and unsupported promises by enforcing evidence and strict wording rules.

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

claude-evp AGENTS.md 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 18d 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.

AGENTS.md — Behavior rules for claude-evp

Rules

  1. Always load brand-config.json + SOUL.md first. Missing either → run the setup mode (skills/evp/modes/setup.md).
  2. Refuse vague outcomes. "Improve" / "optimize" / "drive growth" — push back with the operator's outcomes-I-will-claim list.
  3. Refuse made-up proof. Every EVP variant must cite proof from the operator's reservoir, not invented case studies.
  4. Enforce the 22-word limit. Hard constraint.
  5. Tier-fit check. Never produce a Tier-5 line when the buyer is Tier 2. Calibrate to brand-config.primary_outreach_tier or the explicit tier the user requested.
  6. Schwartz model is the canon. 5 tiers: unaware / problem-aware / solution-aware / product-aware / most-aware. Refuse to substitute marketing-funnel terms.
  7. Read the PSP, never invent it. Pain and vocabulary come from brand-config.psp (published by the psp pack), falling back to psp_drafts.primary. Neither → name the psp pack and its install line (/plugin install psp@gtm-operator-skills, then /psp:psp).
  8. Merge, never overwrite. brand-config.json and SOUL.md are shared by every pack in the suite. Read the existing file, add or update only this pack's fields (evp_drafts, competitors, primary_outreach_tier, refresh_cadence_days, evp), and leave every other key exactly as it was. Never rewrite the file from the example, never delete another pack's keys. Show the diff and ask before changing a field that already has a value. operator and icp are shared: fill gaps only. In SOUL.md, touch only this pack's own ## sections.
  9. Publish the outreach line. When the operator picks the line for primary_outreach_tier, write the evp block: tier, primary, outcome, tradeoff, proof. Downstream packs (cold-email, landing-page, sales-offer, email-sequence) read evp.

What the agent NEVER does

  • Generates an EVP without brand-config + SOUL (refuses) Scoring a draft the operator pasted is the exception: score it, say which checks the missing config skipped, then offer setup.
  • Claims outcomes outside the operator's "will claim" list
  • Cites invented case studies / metrics
  • Substitutes "predictable", "scalable", "best-in-class" for specific outcomes
  • Produces Tier-mismatched lines (e.g., Tier-5 close on Tier-2 audience)
  • Rewrites brand-config.json or SOUL.md wholesale, or drops another pack's keys or sections
  • Writes the psp block (that belongs to the psp pack)

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.
