blade-and-contract

blade-and-contract is a skill for Codex from tokenbender/agent-guides. It costs 68 tokens per session (1,005 once invoked), scanned A, original, Apache-2.0.

A writing framework for making claims attention-grabbing while defining the limits and evidence that make them accurate. It separates the provocative central statement from its precise operational meaning.

In plain words
What is it for?
Use it to write or review proposals, essays, launches, social posts, names, narratives, and debates that need a distinctive point of view.
Why use it?
It helps sharpen positioning and arguments without allowing bold language to become vague or unsupported.

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

blade-and-contract 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 6d 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.

Blade and Contract

Use this skill to make language dangerous without making it sloppy.

The core method is simple:

Lead with the blade. Anchor with the contract.

The blade is the sentence that creates attention, discomfort, and a fight. The contract is the operational definition, boundary, protocol, or receipt that makes the sentence true under the intended frame.

Operating Posture

Do not default to timid epistemic humility when the user wants aggro-pull. Preserve provocation when it is strategic. The aim is not to avoid objections; it is to choose objections that drag readers into the user's ontology.

Treat definitional fights as territory, not paperwork. If a reader objects to a word, ask whether that objection exposes an old or weak category. Make the response force the critic to argue inside the user's frame.

Keep the claim bold at the level of concept and exact at the level of operation.

Workflow

  1. Identify the blade.

    • What sentence would make the target reader stop, object, quote, or argue?
    • Keep it short enough to travel.
    • Prefer category-shifting language: "X is not Y; X only counts when Z."
  2. Identify the contract.

    • Define the object, denominator, intervention, protocol, metric, scope, or constraint that makes the blade defensible.
    • Do not apologize for the contract. State it as the battlefield.
    • Convert caveats into doctrine: "This is not a weakness; this is the object we are isolating."
  3. Redirect objections.

    • Do not soften merely because an objection is predictable.
    • Ask whether the objection is actually bait: can it be turned into "you are using the wrong definition"?
    • Make the critic choose between accepting the contract or explicitly arguing for a narrower ontology.
  4. Remove weak attack surfaces.

    • Cut ambiguity that lets critics attack a claim the user did not mean.
    • Preserve ambiguity that usefully pulls attention only if the follow-up contract snaps shut.
    • Replace loose hype with precise provocation.

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.
