What is postmodernist?

A critique method for reviewing strategy, positioning, and marketing writing at the level of its assumptions and audience.

Use it to pressure-test AI-written mission statements, plans, product briefs, launch material, or other strategic prose.

It helps uncover vague framing, hidden exclusions, and polished claims that may sound convincing without being well grounded.

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	$0.00042	$0.00744
Opus 5.5	$0.00017	$0.00298
Sonnet 5.5	$0.00008	$0.00149
Haiku 4.5	$0.00004	$0.00074

Security

Grade A, and why

postmodernist 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.

Postmodernist Critique

Overview

Use this skill to pressure-test AI-generated prose that sounds polished, reasonable, and slightly wrong. Treat the text as something to debug and rebuild, not something to defend.

Use This Skill For

Mission statements, positioning docs, launch plans, PRDs, strategy memos, investor decks, marketing copy, and similar prose that was drafted by AI
Requests to critique, audit, pressure-test, or rewrite AI-generated text at the level of framing, assumptions, audience, or rhetoric
Cases where the user wants to know what the text cannot see, who it excludes, or why it reads as generically "AI"

Do Not Use This Skill For

Factual verification, legal or medical review, or anything that depends on current citations
Grammar cleanup, proofreading, tone softening, or light copyediting without structural critique
Code, debugging, data analysis, or non-prose tasks

Working Method

Silently scan the text through all six lenses before drafting.
Keep the one to three lenses that reveal different structural problems. Drop overlaps.
Prioritize what is hidden, flattened, overgeneralized, overpolished, or suspiciously frictionless.
Treat the text as raw material to rebuild for the user's purpose, not as an author's intent to explain away.

Output Modes

Default critique

Use this for most requests. Write short continuous prose with no bullets or headers. End with:

one sentence that reframes the whole text
for persuasive or strategic text, one concrete revision direction on a new line beginning with Revision:

Lens-specific critique

If the user explicitly names a lens or theorist, focus on that lens. In this mode, you may name the lens in the answer because the user asked for it.

Structured strategy audit

Only use this when the user explicitly asks for a structured audit, memo, deliverable, or presentation-ready review. In that case, use references/ai-strategy-auditor.md and format the answer in these sections:

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.
