wayfinder

wayfinder is a skill for Codex from tsai09495/matt-pocock-engineering. It costs 35 tokens per session (1,444 once invoked), scanned A, original, MIT.

A planning method for large engineering efforts whose decisions depend on one another. It creates durable decision tickets so the work can be understood and continued across sessions or by multiple people.

In plain words
What is it for?
Use it only when explicitly choosing Wayfinder for a large, long-running, or greenfield effort with many connected uncertainties. For smaller or already-understood work, its guidance points toward a spec or task-ticket workflow instead.
Why use it?
It helps resolve major unknowns before implementation when ordinary planning would not be reliable. It keeps the project focused on decisions and dependencies instead of letting important questions remain hidden.

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 12d 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.

Wayfinder

Wayfinder pushes back the fog around a destination by resolving decisions, not by building deliverables. It is explicit-only because it creates a heavier, durable cross-session workflow.

Read:

  • routing-policy.md for entry and exit routing;
  • quality-baseline.md for side-effect boundaries;
  • the configured docs/agents/issue-tracker.md for tracker-specific map, dependency, frontier, claim, and resolve operations.

Use the current agent by default. Parallel research and ticket workers follow optional-enhancements.md.

Entry gate

Wayfinder fits only when all or most are true:

  • the destination cannot be planned reliably within one agent session;
  • several unknowns depend on one another;
  • the work is greenfield, a huge feature, or long-range restructuring;
  • ordinary grilling would consume the context before a buildable spec emerged;
  • a durable map is needed across sessions or participants.

No-fog early exit

Exit before creating a map when the destination is already clear enough to specify or split. Recommend:

  • grill-with-docs for a manageable set of decisions;
  • to-spec for an already-understood destination;
  • to-tickets for an already-approved plan;
  • implement for one bounded work item.

Being large is not enough. Wayfinder requires decision fog.

Core model

  • Destination — the outcome the user wants, described without pretending the route is known.
  • Map — a durable index of destination, notes, decisions so far, fog, ticket links, and current frontier.
  • Fog — important unknowns or decisions that prevent a trustworthy specification.
  • Decision ticket — one bounded question whose answer removes fog. It produces an answer, not a product feature.
  • Blocking edge — another ticket whose answer is required first.
  • Frontier — open, unclaimed tickets whose blockers are resolved.

The map is an index, not a giant document. Put detailed evidence and conclusions in ticket answers or durable linked artifacts.

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.
