ferrox-mempalace-recall

ferrox-mempalace-recall is a skill for Claude Code from FerroxLabs/ferrox-factory. It costs 25 tokens per session (1,510 once invoked), scanned A, a copy of gsd-mempalace-recall, MIT.

A planning-time recall workflow that retrieves earlier decisions, successful approaches, and unexpected lessons from MemPalace. MemPalace is a memory store for project knowledge.

In plain words
What is it for?
Use it before planning when MemPalace is enabled and recall is turned on for the project.
Why use it?
It brings relevant past experience into planning so the same decisions and surprises do not have to be rediscovered.

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

ferrox-mempalace-recall 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 8d 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.

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:

Ferrox > 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 ferrox-tools config-get -- it hard-exits on missing keys unless --default is passed.

  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:

Ferrox > MEMPALACE RECALL

MemPalace memory is disabled. To activate:

  node <runtime-home>/ferrox-core/bin/ferrox-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.

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.
