At a glance

Files a GSD phase artifact into MemPalace and mirrors its decision facts into the temporal knowledge graph, as a best-effort step that never blocks a phase.

  • Works in 5 steps: Banner → Config Gate → Resolve target → …
  • Saving a phase's CONTEXT, PLAN or SUMMARY file into MemPalace after the phase ends
  • SKILL.md covers Step 0 -- Banner, Step 1 -- Config Gate, Step 2 -- Resolve target and Step 3 -- File verbatim…, plus 2 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

At the end of a discuss, plan or verify phase, this step files the matching artifact (CONTEXT.md, PLAN.md or SUMMARY.md) into a MemPalace room: decisions, planning or milestones. It first reads .planning/config.json and stops quietly unless the mempalace setting is enabled and artifact capture is not turned off. The wing comes from the config, the project code or the repo directory name.

Filing is verbatim and idempotent: it checks for duplicates by a deterministic drawer ID in interactive runs and relies on the miner's content hashing in headless runs, using MemPalace MCP tools when registered and the mempalace CLI otherwise. Any error or timeout ends the step so the phase carries on. Confirmed problem-and-fix pairs belong to a separate capture step at execute time. The skill needs Read, Bash and Grep access and is meant to run from the command system, which supplies its arguments.

When your agent uses it

  • Saving a phase's CONTEXT, PLAN or SUMMARY file into MemPalace after the phase ends
  • Recording decision facts in MemPalace's temporal knowledge graph
  • Checking why MemPalace capture is disabled for a project

Example prompts

  • “Capture the PLAN.md from this phase into MemPalace.”
  • “Why did MemPalace capture do nothing after the discuss phase?”

Requirements

  • MemPalace enabled in .planning/config.json
  • The MemPalace MCP server or the mempalace CLI
  • Pre-approved tools (allowed-tools): Read, Bash, Grep

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. Banner
  2. Config Gate
  3. Resolve target
  4. File verbatim (idempotent)
  5. Report

What it can do on your machine

Read from SKILL.md and the folder at commit 5d987cc. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Bash
    • Grep

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • mempalaceofficial.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

GSD MemPalace Capture loads about 1.6k tokens when it runs. Until then it costs about 26 tokens; SKILL.md has 558 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~26
When it runs · the whole SKILL.md, loaded when a task matches
~1.6k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

[CONTEXT.md|PLAN.md|SUMMARY.md]

<arguments>$ARGUMENTS</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 CAPTURE

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.

  1. Read .planning/config.json with the Read tool.
  2. If the file does not exist, or config.mempalace is absent, or config.mempalace.enabled !== true, or config.mempalace.capture_artifacts === false: display the disabled message and STOP.
  3. Otherwise proceed to Step 2.

Disabled message:

GSD > MEMPALACE CAPTURE

MemPalace capture is disabled (mempalace.enabled / mempalace.capture_artifacts).
Nothing was filed; the loop proceeds normally.

This step is onError: skip at discuss:post / plan:post / verify:post -- capture never fails a phase.

Step 2 -- Resolve target

  1. Artifact. Take the artifact from the <arguments> block. If absent, infer from the loop point: discuss:post → CONTEXT.md, plan:post → PLAN.md, verify:post → SUMMARY.md.
  2. Room. Map artifact → room:
    • CONTEXT.md → decisions
    • PLAN.md → planning
    • SUMMARY.md → milestones (Confirmed problem→fix pairs go to problems — see the capture-problems fragment used at execute:wave:post.)
  3. Wing. config.mempalace.wing if non-empty, else config.project_code, else the repo directory name.
  4. Mode / transport. Read config.mempalace.memory_mode. Prefer MCP (mempalace_*) when your MemPalace MCP server is registered and your runtime permits those tools; otherwise use the mempalace CLI (covered by this skill's Bash allow-tool), as in mempalace-recall.

Step 3 -- File verbatim (idempotent)

On any error or timeout, stop and let the phase continue -- capture is best-effort.

  1. Dedup first. Interactive: mempalace_check_duplicate on the artifact's deterministic drawer id. Headless: rely on mempalace mine's content-hash idempotency.

  2. Add the drawer (verbatim). File the exact artifact text into room: <room> of wing: <wing> with provenance (source_file, phase id). Interactive: mempalace_add_drawer. Headless: see below.

    mempalace mine has no --room flag — only search accepts --room (CLI reference: https://mempalaceofficial.com/reference/cli.html). Room assignment is driven by detect_room() matching folder-path segments against the rooms: list in mempalace.yaml (mining guide: https://mempalaceofficial.com/guide/mining.html — "Rooms are auto-detected from your folder structure"; config reference: https://mempalaceofficial.com/guide/configuration.html). Stage the artifact under a room-named folder so detect_room() assigns it correctly:

    bash
    STAGE=".planning/.mempalace-stage"
    # One-time: declare the GSD room taxonomy so detect_room() recognizes these folders
    mkdir -p "$STAGE"
    [ -f "$STAGE/mempalace.yaml" ] || cat > "$STAGE/mempalace.yaml" <<'YAML'
    # Each entry MUST be a dict with a `name` key (the miner's detect_room()
    # indexes room["name"] — a bare-string list crashes _mine_impl with
    # TypeError: string indices must be integers, not 'str'). Optional fields:
    # `description`, `keywords` (matched against folder-path segments).
    rooms:
      - name: decisions
      - name: planning
      - name: milestones
      - name: problems
      - name: general
    YAML
    # Suppress MemPalace cache artifacts written into the scanned tree
    [ -f "$STAGE/.gitignore" ] || echo "mempalace_embedder.json" > "$STAGE/.gitignore"
    # Stage under <room>/<phase-id>/<basename> — stable path so mine's content-hash
    # idempotency (file_already_mined keys on absolute source_file + mtime) deduplicates
    # instead of creating duplicate drawers on re-runs.
    ROOM_DIR="$STAGE/<room>/<phase-id>"
    mkdir -p "$ROOM_DIR"
    cp "<artifact-path>" "$ROOM_DIR/<basename>"
    # Mine with --wing only — no --room flag; detect_room() assigns from the folder path.
    # --daemon --background (#4700): MemPalace wraps every mine in a per-palace
    # lock; a concurrent writer would make a foreground mine exit 1
    # (MineAlreadyRunning) and this onError: skip step would silently drop the
    # capture. The background queue defers the job until the lock frees.
    mempalace mine "$STAGE" --wing <wing> --daemon --background
  3. Mirror KG facts unless config.mempalace.mirror_kg === false (registry default is true — an absent key means enabled): extract decision/delivery facts and mempalace_kg_add them with valid_from = the phase date (e.g. (<project>, decided, <decision>) from CONTEXT; (<phase>, delivered, <capability>) from SUMMARY). Under augment these are an additive mirror of GSD's native .planning/graphs/. Under kg_backend/replace the palace KG is the authoritative fact store — GSD still produces .planning/graphs/ through its normal graphify, so an unreachable palace never loses a fact.

  4. Re-running a phase MUST NOT create duplicate drawers (deterministic ids + check_duplicate).

Show full SKILL.md (109 more words)Show less

Step 4 -- Report

Print a one-line summary: Filed <artifact> → <wing>/<room> (<n> KG facts), Capture queued — palace busy; MemPalace will file it when the lock frees (the background mine was deferred behind another writer), or MemPalace capture skipped — <reason> (#4700: a skipped capture is never silent).

Anti-Patterns

  1. DO NOT let any MemPalace error fail the step -- capture is onError: skip.
  2. DO NOT write lossy summaries -- store the verbatim artifact text (AAAK compression is a separate, optional index).
  3. DO NOT prune or delete drawers here -- pruning (sync --apply) is the curator agent's job at ship:post, wing-scoped only.
  4. DO NOT skip the config gate or the dedup check.
