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.

1. Read .planning/config.json with the Read tool.
2. If the file does not exist: write the "unavailable" stub (Step 4) and STOP.
3. 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.

Step 2 -- Resolve wing, mode, and transport

1. Wing. Use config.mempalace.wing if non-empty; otherwise derive from config.project_code; otherwise fall back to the repository directory name.
2. Mode. Read config.mempalace.memory_mode (augment | kg_backend | replace, default augment). It sets how authoritative the palace is during recall:
   • augment — the palace is an additional layer; read native memory (.planning/graphs/, STATE) too and treat the palace as supplementary.
   • kg_backend — for knowledge-graph facts, query the palace's temporal KG first, as the primary source; fall back to .planning/graphs/ when the palace is unreachable. Non-KG drawer recall stays additive.
   • replace — resolve recall through the palace as the source of truth; consult native artifacts only as a fallback when the palace is unreachable. In every mode an unreachable palace degrades to native memory — recall never blocks (onError: skip).
3. Transport. Prefer the MCP tools (mempalace_*) in interactive runs when your MemPalace MCP server is registered and your runtime permits those tools. Otherwise — headless/cron/autonomous runs, or runtimes that don't grant the MemPalace MCP tools — use the CLI (mempalace wake-up, mempalace search), which this skill's Bash allow-tool always covers. If neither is reachable, go to Step 4.
4. Topic. Read the phase CONTEXT.md (the consumed artifact). Derive a short search query from its title, goal, and key decisions.

Step 3 -- Retrieve (read-only)

All calls in this step are side-effect-free. On any error or timeout, stop retrieving and write whatever was gathered (or the stub) -- never raise. This skill reads only the palace; GSD's planner reads native memory (.planning/graphs/, STATE) regardless. So under kg_backend/replace an unreachable palace falls back to that native memory automatically — reflect that in the stub (Step 4) rather than implying memory is gone.

1. Wake up (cheap, ~600--900 tokens):
   • Interactive: read the wing identity/summary, then mempalace_search.
   • Headless: mempalace wake-up --wing <wing>.
2. Targeted search:
   • Interactive: mempalace_search(query=<topic>, wing=<wing>).
   • Headless: mempalace search "<topic>" --wing <wing>.
3. Knowledge-graph facts (unless config.mempalace.mirror_kg !== false — registry default is true, an absent key means enabled): mempalace_kg_query / mempalace_kg_timeline for decisions relevant to the topic and their validity windows. Under augment the palace KG supplements GSD's native .planning/graphs/ — combine both, do not treat the palace as the sole source. Under kg_backend or replace the palace KG is the primary graph source — query it first and use .planning/graphs/ only as a fallback when the palace is unreachable.
4. Dedup the returned drawers/facts; keep the top results.

Step 4 -- Write MEMORY-RECALL.md

Write MEMORY-RECALL.md in the current phase directory. The planner consumes it.

When recall succeeded, structure it as:

# Memory Recall (MemPalace)

_Wing: <wing> · Mode: <mode> · Transport: <mcp|cli>_

## Prior decisions
- <decision> — <provenance: drawer id / kg fact, valid_from>

## Patterns
- <pattern> — <provenance>

## Surprises / gotchas
- <surprise> — <provenance>

When MemPalace is unreachable, write the stub and continue. Under kg_backend/replace, name the native fallback so the planner knows memory is not gone — only un-augmented by the palace this run:

# Memory Recall (MemPalace)

_MemPalace unavailable at recall time — falling back to GSD native memory (`.planning/graphs/`, STATE). No palace recall this run._

Anti-Patterns

1. DO NOT let any MemPalace error fail the step -- recall is onError: skip.
2. DO NOT write to the palace from this skill -- recall is read-only; capture is a separate skill.
3. DO NOT paste raw search output into the file -- distil to decisions/patterns/surprises with provenance.
4. DO NOT skip the config gate.
