Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00136 | $0.02007 |
| Opus 5 | $0.00068 | $0.01004 |
| Sonnet 5 | $0.00027 | $0.00401 |
| Haiku 4.5 | $0.00014 | $0.00201 |
Grade A, and why
narrative-fallacy 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 9d 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.

Narrative Fallacy
Overview
The narrative fallacy is the tendency to construct retrospective causal stories that make past events seem inevitable — even when those events were largely random or contingent. Named by Nassim Taleb (The Black Swan, 2007, ch. 6); grounded in Kahneman's "illusion of understanding" (Thinking, Fast and Slow, 2011, ch. 19). Three structural drivers: causal hunger (brains auto-infer causation from sequence), retrospective selection (only survivors are visible), coherence comfort (tidy stories feel true).
Composes with hindsight-bias, survivorship-bias, black-swan, first-principles, and probabilistic-thinking.
When to Use
- You're reading a business case study or founder biography and drawing lessons
- A post-mortem produces a satisfyingly neat single root cause
- A pundit explains a market or political event with one dominant narrative — after it happened
- You're constructing a strategy based on what worked at another company
- Someone says "the story is too neat," "after-the-fact rationalization," or "post-hoc explanation"
- A sweeping tech-transformation story is driving action — "AI changes everything," AI capex / GPU spend is "self-justifying," "AI bubble," or a viral demo is standing in for measured ROI
Not when: causal structure is genuinely well-understood (physics, tested medicine); the narrative is a hypothesis to test; storytelling is the medium and you already treat it as a compression.
Coaching Novices (Adaptive Front Door)
- Engine mode: user has a specific compelling narrative → run The Process directly.
- Coach mode: user is new or has no concrete case → guide step by step.
In Coach mode, respond one step at a time. Each [WAIT] is a hard stop — output only that step's question, then stop.
- One-line: when a story explains the past with neat causal clarity, suspect the narrative fallacy — minds construct causal sequences automatically, even from random events.
- Check fit: physical sciences have genuine causal understanding; most business / political / historical narratives don't.
- Elicit: what's the story? What causes does it identify? What outcome does it explain?
[WAIT — do not advance until user responds]
- Probe: what does the narrative strip out (non-survivors, contingencies, unknowns at the time)? Would the narrative survive if the outcome had been different?
[WAIT — do not advance until user responds]
- Close: reframe the narrative as a compressed retrospective + name the operational implication if lessons were about to be drawn.
[WAIT — do not advance until user responds]
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

narrative-fallacy is a skill published in the GitHub repository deciqAI/knowledge-skills (10 stars, last pushed 10d ago), licensed MIT. It adds 136 tokens to every session and 2,007 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
