wayfinder

wayfinder is a skill for Claude Code, Codex from aethrox/doctrine. It costs 73 tokens per session (1,082 once invoked), scanned A, original, MIT.

A step-by-step planning method for large or unclear work. It records and settles one dependent decision at a time until the destination is clear.

In plain words
What is it for?
Use it to turn a vague idea into a ready-to-build specification, settle design questions, or plan a migration before implementation begins.
Why use it?
It prevents teams from trying to solve every uncertainty in one oversized document. Each decision becomes explicit, so earlier choices can be checked when the goal changes.

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

wayfinder 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 10d 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.

How it starts

The opening of the file, as written. The whole thing — 62 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Wayfinder

Some work isn't unclear because nobody's thought about it; it's unclear because it depends on decisions that haven't been made yet, and those decisions depend on others. This skill's defining constraint, from the RFC process IETF and Rust use for exactly this problem, is to chart large, uncertain work as a sequence of individually-written decisions, each one settled and recorded before the next is opened, rather than one big document trying to resolve everything at once.

Once the path is clear (no open decisions block the destination anymore), hand off to spec-to-tickets for execution. Wayfinder's job ends where a spec's job begins.

Phase 1: Name the destination

Before charting anything, state what reaching the end of this effort looks like: a spec ready to hand off, a design decision locked in, or a migration completed. One or two lines, fixed before anything else, because it's what decides which open questions are actually in scope and which aren't. A destination that shifts mid-effort invalidates decisions already made against the old one; if it must shift, say so explicitly and re-check standing decisions against the new destination rather than silently continuing.

Phase 2: Chart the open decisions

Fan out breadth-first across the whole space (every open question standing between here and the destination) rather than diving deep on the first one found. For each:

  • State the decision precisely enough that "resolved" and "not yet resolved" are unambiguous.
  • Note what it blocks and what blocks it. A decision that depends on another isn't ready to open yet.
  • If a genuine open area exists but can't be phrased as a precise question yet, leave it as unspecified rather than forcing it into a premature decision; a vague decision produces a vague, unusable answer.

If this pass surfaces no real open questions (the path to the destination is already obvious), stop here. The work doesn't need staging; it needs a spec.

Phase 3: Resolve one decision at a time

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.

wayfinder is a skill published in the GitHub repository aethrox/doctrine (18 stars, last pushed 28d ago), licensed MIT. It adds 73 tokens to every session and 1,082 once invoked, about $0.0004 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.
