fpf-problem-solving

A first-principles problem-solving framework for breaking down difficult questions, comparing options, and recording the reasoning behind decisions.

In plain words
What is it for?
Use it to decompose complex problems, define what success means, evaluate alternatives, coordinate different viewpoints, and test whether a conclusion is well founded.
Why use it?
It makes assumptions, missing evidence, trade-offs, and conclusions easier to inspect instead of relying on an unsupported first answer.

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

fpf-problem-solving 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 2d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/split_spec.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 141 lines — stays where its author put it; the contents beside it link to each section on GitHub.

First Principles Framework (FPF)

An "Operating System for Thought" — a transdisciplinary architecture for reasoning, written in human- and machine-readable pseudo-code. FPF turns raw intelligence (human or machine) into organisationally usable reasoning: explicit bounded contexts, auditable artefacts, multi-view descriptions, and disciplined hand-offs between specialised actors.

Use cases

Use FPF whenever you need to think more rigorously than the situation's default.

  • Decompose a messy, cross-domain problem into parts that can be reasoned about independently
  • Make a high-stakes decision with incomplete evidence — and know what evidence is still missing
  • Get a mixed team to reason together without vocabulary collisions or hidden assumptions
  • Audit whether a conclusion is well-founded or just plausible
  • Transform or transfer an insight without losing its subject, precision, or stated limitations
  • Structure a proposal that must survive scrutiny from multiple expert perspectives
  • Generate alternatives systematically instead of anchoring on the first idea
  • Define what "better" means before comparing options
  • Classify what kind of problem you're facing before searching for solutions
  • Plan how an AI agent should select and sequence its tools under budget and trust constraints
  • Make a decision under uncertainty — identify options, weigh evidence, and commit with an auditable rationale
  • Establish whether X causes Y — or just correlates — and determine what intervention would work
  • Publish a stable multi-view artifact without changing the source semantics
  • Assemble or check a public framework publication form while preserving product-specific bodies and references
  • Develop a holder system's capability for a named Work family and verify transfer in representative Work
  • Synthesize source ontologies for one bounded authoring decision without flattening their local meanings
  • Refresh a SoTA pack, benchmark, or evidence trail when evidence decays or telemetry changes
  • Synthesize architecture candidates, compare structural options, or repair modularity/reuse claims
  • Detect an ontic candidate, decide its first-use disposition, and govern whether a new concept or U-kind should be introduced instead of just renamed
  • Identify the exact system that acts or is intended to change, then trace a lost path from outside use to architecture, production, and recursive builders
  • Discover other systems that may bear relevant consequences before a decision closes
  • Recover a reusable method cautiously from several performances, logs, or observations without treating the evidence as the method itself
  • Choose the next action during ongoing work when current facts, authority, and stop conditions matter
  • Recover the actual performer/support configuration for Work and test what survives interruption, handoff, delay, or reconfiguration
  • Compare what a finite addition, replacement, or intervention contributes relative to the current configuration
  • Clarify what a claim about human, machine, organizational, or cultural “learning” actually says changed
  • Apply one selected FPF pattern to a current question and stop at the first useful result

What ships with it

60 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.

Changes

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.

fpf-problem-solving is a skill published in the GitHub repository CodeAlive-AI/ai-driven-development (131 stars, last pushed 4d ago), licensed MIT. It adds 196 tokens to every session and 4,342 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 2026-08-30.
