plan-work-too-big-for-one-session

plan-work-too-big-for-one-session is a skill for Claude Code, Codex from everywan-dev/claude-code-engineering. It costs 51 tokens per session (2,896 once invoked), scanned A, original, Apache-2.0.

A planning method for work too large to fit in one coding-agent session. It records open decisions as tickets in the project's issue tracker until the route to the finished result is clear.

In plain words
What is it for?
Use it to plan migrations, specifications, course content, or other large efforts where the main difficulty is deciding what must be settled first.
Why use it?
It replaces a vague, oversized idea with a shared map of decisions. This helps teams agree on important choices before implementation begins.

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

plan-work-too-big-for-one-session 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 4d 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 — 133 lines — stays where its author put it; the contents beside it link to each section on GitHub.

A loose idea has arrived, too big for one agent session, and wrapped in fog: the way from here to the destination isn't visible yet. Wayfinding is about finding that way, not charging at the destination. This skill charts the way as a shared map on the repo's issue tracker, then works its decision tickets (questions whose resolution is a decision, not slices of a build to execute) one at a time until the route is clear.

The destination varies per effort, and naming it is the first act of charting: it shapes every ticket. It might be a spec to hand off and iterate on, a decision to lock before planning starts, or a change made in place like a data-structure migration. The map is domain-agnostic: engineering work, course content, whatever fits the shape.

Plan, don't do

Wayfinder is planning by default: each ticket resolves a decision, and the map is done when the way is clear, with nothing left to decide before someone goes and does the thing. The pull to just do the work is usually the signal you've reached the edge of the map and it's time to hand off. An effort can override this in its Notes, carrying execution into the map itself, but absent that, produce decisions, not deliverables.

Refer by name

Every map and ticket is an issue, so it has a name: its title. In everything the human reads (narration, the map's Decisions-so-far), refer to it by that name, never by a bare id, number, or slug. A wall of #42, #43, #44 is illegible; names read at a glance. The id and URL don't vanish; a name wraps its link, but they ride inside the name, never stand in for it.

The Map

The map is a single issue on this repo's issue tracker, labelled plan-work-too-big-for-one-session:map, the canonical artifact. Its tickets are child issues of the map.

The map is an index, not a store. It lists the decisions made and points at the tickets that hold their detail; a decision lives in exactly one place, its ticket, so the map never restates it, only gists it and links.

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.
