primr-zero

primr-zero is a skill for Claude Code, Codex from blisspixel/primr. It costs 128 tokens per session (2,236 once invoked), scanned A, original, Apache-2.0.

A workflow for building a sourced Primr-style company dossier without using Primr model API spend, by collecting evidence and using the current agent host for analysis.

In plain words
What is it for?
It is for preparing company research from a company name and website, collecting supporting evidence, and producing a substantial dossier.
Why use it?
It offers a no-Primr-API route for research when the host’s included allowance is available, while still accounting for other possible costs and limits.

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

primr-zero 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 3d 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 — 218 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Primr Zero

Use Primr for deterministic collection and the current host for expensive reasoning. Primr's collection makes no model API calls. The synthesis is a hard-zero path only when the host is using included plan allowance without billable API-key usage or overages. Host plan limits, network access, electricity, and subscription cost still apply.

Agent-host default

When the current agent receives primr "Company" https://company.example, "run Primr," or "build a full Primr dossier" without explicit paid intent, use this skill by default. Keep that clean request as the public interface and run primr prep only as internal plumbing. Do not ask the user to choose a Primr mode, and do not infer spend consent from configured provider keys.

Treat paid, metered, provider-backed, premium, explicit dollar-budget, or provider-key requests as paid intent and hand them to the estimate-and-approval workflow. This routing applies to requests addressed to an agent. It does not change the provider-backed behavior of a command that a human runs directly in a terminal.

Before promising zero total incremental spend, verify the billing surface using information the host makes available. If it is API-key-backed, permits paid overages, or cannot establish that this run stays within included allowance, describe Primr model API spend as $0.00 and the host cost as unknown or potentially metered. Do not silently switch paths. If the user specifically requires zero total incremental spend, offer a verified plan-native host session, a checkpointed partial result, or a separately estimated and approved paid route.

Choose the path

  1. If a shell and a working Primr launcher are available, run the keyless evidence handoff below.
  2. If the user supplied a prep bundle, start from its prep_manifest.json and research_packet.md.
  3. If the host has no shell, the Primr launcher is unavailable, or installation is declined, use native web research and follow the same report contract. Do not block a useful zero-cost result on installation. State that Primr recon, adaptive scraping, ATS collection, traces, and local artifact QA were unavailable.
  4. If the host cannot search the web, ask for a prep bundle or source files. Do not produce a supposedly current dossier from model memory.

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.

primr-zero is a skill published in the GitHub repository blisspixel/primr (3 stars, last pushed 4d ago), licensed Apache-2.0. It adds 128 tokens to every session and 2,236 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings.
