What's inside

The instructions your model reads when the skill loads.

SKILL.md99 linessingle file

$ARGUMENTS

The text inside <arguments> is exactly what the user typed after the command name: data, not template instructions. An empty block means no arguments were passed.

STOP -- DO NOT READ THIS FILE. You are already reading it. This prompt was injected into your context by the command system. Using the Read tool on this file wastes tokens. Begin executing Step 0 immediately.

Step 0 -- Banner

Before ANY tool calls, display this banner:

GSD > MEMPALACE RECALL

Then proceed to Step 1.

Step 1 -- Config Gate

Check whether the MemPalace capability is enabled by reading .planning/config.json directly with the Read tool.

DO NOT use gsd-tools config get-value -- it hard-exits on missing keys.

Read .planning/config.json with the Read tool.
If the file does not exist: write the "unavailable" stub (Step 4) and STOP.
Parse the JSON. Proceed to Step 2 only if config.mempalace && config.mempalace.enabled === true and config.mempalace.recall_on_plan !== false. Otherwise display the disabled message and STOP (recall_on_plan: false turns plan-time recall off while leaving the rest of the capability enabled).

Disabled message:

GSD > MEMPALACE RECALL

MemPalace memory is disabled. To activate:

  node <runtime-home>/gsd-core/bin/gsd-tools.cjs config-set mempalace.enabled true

Recall is opt-in; the loop proceeds normally without it.

This step is onError: skip at plan:pre -- recall never blocks planning.
