memory-keeper SKILL.md skillA
memory-keeper from hdl-tools/digital-chip-design-agents is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add hdl-tools/digital-chip-design-agents/memory-keeper@v1.0.0Pins v1.0.0 in mdr.lock. Pin the fingerprint instead.

Distil accumulated experience records (experiences.jsonl) into updated domain knowledge summaries (knowledge.md) for any chip-design domain. Run after every 10 orchestrator sessions, or on demand when a domain has collected new issue/fix patterns.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Skill: Memory Keeper
## Invocation
```text
/chip-design-infrastructure:memory-keeper [--domain <name>] [--all] [--min-records <n>] [--init]
```
- `--domain <name>` — distil a single domain (e.g. `synthesis`, `sta`, `pd`)
- `--all` — distil every domain that has an `experiences.jsonl` with enough records
- `--min-records <n>` — minimum record count to proceed (default: 5); skip domains below threshold
- `--init` — resolve and seed the central memory root, migrating any repo-local runtime data
(runs `memory_root.py --init`); no distillation. Use once after install or to inspect the location.
If neither `--domain` nor `--all` nor `--init` is given, prompt the user to choose.

## Memory Root Resolution
Memory does **not** live at a fixed relative `memory/` path. The active root is resolved by
`memory_root.py` (the single source of truth that `distill.py` and `tools/qor_trends.py` import),
in this priority order:
1. an explicit `--memory-root PATH` argument
2. the `$CHIP_DESIGN_MEMORY_ROOT` environment variable
3. the central default `${XDG_DATA_HOME:-$HOME/.local/share}/chip-design-agents/digital/memory`
(Windows: `%LOCALAPPDATA%\chip-design-agents\digital\memory`)

How to install
mdr add hdl-tools/digital-chip-design-agents/memory-keeper@sha256:e553ebb486c9b17dThe line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
