plan

A planning command for revising how an existing epic or feature is divided into smaller features or tasks. An epic is a large body of work, while a feature is a smaller user-facing capability.

In plain words
What is it for?
Use it to refine an epic’s linked features or a feature’s tasks after reviewing the relevant planning files and current statuses.
Why use it?
It helps find missing, outdated, incorrectly ordered, split, or duplicated pieces of an existing plan. It also shows which work is complete, active, or waiting.

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 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.

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

Plan (/agn:plan <level>)

Arguments

Position Variable Value
$0 level epic or feature

Argument validation

If $0 is missing, stop and ask:

"What level — epic or feature?"

If $0 is not one of epic, feature, stop and list the valid set.

Dispatch

Read $0. Run exactly one of the branches below.


$0 = epic

Preconditions

The epic file must exist under tasks/epics/. If it does not, stop and direct the user to /agn:define epic.

Workflow

  1. Locate — Confirm the epic slug. Read the epic file and its current ## Linked features. List the existing feature files under tasks/features/ that carry epic: <slug>.

  2. Identify the decomposition gap — Ask the user what needs to change: a missing feature, an obsolete feature, reordering, splitting a feature, merging two. Surface what is currently in done vs active vs backlog so the user knows what is in flight.

  3. Delegate to the Planner. Invoke via the Agent tool with subagent_type: planner and the following brief:

    • level=epic
    • mode=refine
    • title=<existing epic file path>
    • initial_scope=plan-only — <user description of decomposition change>; existing features: <list>
    • upstream=<docs/vision.md, docs/spec.md, docs/architecture.md if relevant>

    The Planner returns a ## Decomposition delta — features to add, remove, or re-order — plus a one-sentence rationale. It does not touch the epic body (that's /agn:design epic).

  4. User review — Show the proposed feature changes. Iterate until approved.

  5. Persist

    • For each new feature: invoke /agn:define feature --epic <slug> (or taskman.sh new feature --epic <slug> if the user provides bodies inline).
    • For each obsolete feature still in backlog: confirm with the user, then taskman.sh discard <path>.
    • For ordering changes: edit the epic's ## Linked features list in place via the Edit tool.
    • Features already in active or done are not modified; surface them in the report.

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.

plan is a skill published in the GitHub repository AgentureHQ/agenture-loop (2 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 43 tokens to every session and 1,181 once invoked, about $0.0002 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.
