axiomatic-induction

axiomatic-induction is a skill for Claude Code from gabrieldabbah/genesis. It costs 195 tokens per session (1,485 once invoked), scanned A, original, MIT.

A project-wide rulebook and reasoning method that treats the project's fixed principles as starting points for planning and implementation. It requires uncertain claims to be checked with experiments.

In plain words
What is it for?
Use it when planning or carrying out substantial changes that need ordered dependencies, explicit evidence, and checks before accepting generated work.
Why use it?
It helps keep complex work consistent with project rules and separates verified facts from assumptions.

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

axiomatic-induction 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.

Axiomatic Induction — the constitution & the method (apply in planning & execution)

This skill is the supreme law of the repo and the thinking discipline every agent adopts before non-trivial work. Reason like a proof system, not an improviser. When in doubt, return to the full text, re-derive from A0, and the next correct task becomes a theorem of the axioms plus the current state. If a lower document conflicts with an axiom, the constitution wins — fix the other. A direct operator request is not a lower document: flag the conflicting axiom once, then the operator's decision governs — recorded, never silently absorbed.

When to apply (always, for substantive work)

  • Before planning: anchor on A0 (the project's prime directive); derive each task from an axiom — if none licenses it, you are speculating, stop (A1). Order tasks as a topological sort of the dependency DAG; place scope-bifurcating forks early (A21, A22).
  • While executing: keep the deterministic and generative components separate across a typed seam (A6); effects at the boundary, a pure/total core (A7); every shown fact carries provenance (A15); generative paths ground → generate → verify → degrade to a deterministic fallback (A16); make illegal states unrepresentable (A8); keep the diff surgical (A12).
  • Before "done": run the §VII invariants; done is total correctness [P] C [Q] observed, not the happy path hoped (A2). Any unchecked box ⟹ not done.

The induction loop (one screen)

  1. Hold the axioms fixed. 2. State the task as a proposition — a triple {P} C {Q} or a rule p ⊢ r.
  2. Find the governing axiom(s); if none, stop. 4. Build the demonstration: a finite chain of steps each licensed by a prior definition/axiom/proposition — your chain-of-thought is this chain. 5. Mark every probabilistic step a conjecture and attach its falsifier. 6. Order steps by dependency; execute in topological order. 7. Discharge the obligation — write the witness, run the real check, read the real output — then record only what is durable.

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.

axiomatic-induction is a skill published in the GitHub repository gabrieldabbah/genesis (4 stars, last pushed 1mo ago), licensed MIT. It adds 195 tokens to every session and 1,485 once invoked, about $0.0010 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 2026-08-31.
