clipboard-memory（剪贴板内存）

Recall what the user copied on this Mac before reaching for generic search. clipmem maintains a local, privacy-preserving SQLite archive of every clipboard state macOS emits, and exposes a JSON-first CLI built for agents. This package is installed by clipmem agents openclaw install-skill; the canonical cross-agent source lives under skills/clipboard-memory/.

Use this skill when

The user asks things like:

• "what was that command I copied?"
• "show me the URL I copied from Safari earlier"
• "find that snippet, path, note, or link I copied yesterday"
• "give me the exact text I copied, not a summary"
• "what did I copy before I restarted?"
• "paste me back that SQL I was looking at"
• "get the PDF I copied last week"
• "show me everything I copied from Xcode today"

Do not use this skill for

• web search or current-events lookups
• searching the repository or local files the user never copied
• content the user typed but never copied to the clipboard
• anything on a non-macOS machine (clipmem captures NSPasteboard only)

Prerequisites

Before querying, confirm the setup is healthy — otherwise empty results may be a stale watcher, not a true miss:

1. Background capture must be running. clipmem setup is the canonical fix; Homebrew users can also use brew services start clipmem.
2. The binary clipmem must be on PATH with write access to ~/Library/Application Support/clipmem/clipmem.sqlite3.
3. Run scripts/check-setup.sh once per session when results look wrong. It exits 0 on a healthy host, 1 if the watcher is stale, 2 if the binary is missing, 3 if clipmem doctor fails. The prose equivalent is in references/setup-check.md.
4. If OpenClaw cannot see the binary, run clipmem agents openclaw doctor and follow its remediation lines.

Command ladder

Always pick the narrowest command that answers the question, and always pass --format json (or --format toon for plain enumeration) so you can parse the response deterministically.

1. clipmem recall — best-first ranked answer with alternatives. Start here for almost every request.
2. clipmem timeline — chronological capture events (one row per copy), including repeated copies of the same content. Use for "today", "yesterday", "in order", or "every time".
3. clipmem search — direct lexical / FTS matching. Use when you need precise substring hits or the user gave you an exact phrase.
4. clipmem get <snapshot_id> — nested item/representation detail for a single snapshot already in hand.
5. clipmem export <snapshot_id> --item <n> --uti <uti> --out <path> [--force] — raw bytes. Use when the stored content is binary/image/PDF and best_text is empty or partial. Prefer a fresh output path; use --force only to replace an existing regular file.
6. clipmem ocr candidates, clipmem ocr get, clipmem ocr clear, and clipmem storage image-candidates — inspect queued OCR or image optimization work before running batch workflows, or clear one stale OCR result.
7. clipmem settings reset --format json — reset capture policy and ignored apps when the user explicitly asks to restore defaults.
8. clipmem service providers --format json — inspect service provider state without starting or stopping capture.
9. clipmem service revision --format json — inspect archive revision counters without probing service providers.
10. clipmem app settings, clipmem app launch-at-login, clipmem app update-check run, or clipmem app quit with --format json — inspect or change menu bar app preferences and app-owned state when the user asks about app defaults, update checks, or quitting the app.
11. clipmem agents context --format json — compact health, settings, app state, recent activity, revision, stats, privacy, and capability context before multi-step work.

Primitive command taxonomy

Primitive commands expose one bounded read or mutation that can be composed directly. Convenience workflows such as recall, setup, purge, ocr run, and storage optimize-images remain useful, but verify uncertain results with search, recent, timeline, or get, and preview broad mutations with candidate or dry-run commands when available.

The full flag reference, JSON envelope, and kind values live in references/commands.md, references/json-schema.md, and references/examples.md.

Critical behaviour rules

• Before answering from a stale, empty, or ambiguous archive, run clipmem agents context --format json and use generated_at, health, settings, app state, recent activity, revision, stats, privacy, and capability fields to decide whether to broaden search or diagnose setup.
• Always use --format json when you will parse the response. --format toon is for token-efficient enumeration only. --format jsonl is for streaming many rows into a pipeline. Never parse md or text.
• Treat recall as a convenience ranking helper, not an authority. For uncertain cases, compose primitive commands in this order: search, recent, timeline, get, then OS follow-through such as pbcopy, open, or open -R.
• Never claim "nothing found" until you have broadened the search once and checked truncated / next_cursor.
• When best_match_confidence is "low" or there are several plausible hits, present the top candidates instead of pretending certainty.
• For exact-text requests, quote best_text verbatim. Do not paraphrase commands, SQL, code, URLs, or file paths unless the user asked for a summary.

Capability map

The repo-side agent-native action parity contract lives in docs/action-parity.md. Use it when you need the maintained map from user-visible outcomes to agent-accessible commands, entity CRUD expectations, and derived-cache boundaries.

Output format rule

• --format json — structured output. Retrieval envelopes are stable within schema_version: 2; management and inspection commands use command-specific JSON shapes, so parse documented keys directly.
• --format toon — flat, token-efficient list. Prefer for high-cardinality enumeration (timeline, search, recent, recall) when you only need the top fields. Note: get does not support toon.
• --format jsonl — newline-delimited records. Use when streaming many rows into a pipeline.
• --format md / --format text — human-readable previews only; never parse these.

--json is an alias for --format json on search, recent, timeline, get, service revision, capture-once, and doctor.

Which command for which intent

recall vs recent vs timeline:

• recall ranks across the archive and returns a best candidate plus alternatives.
• recent deduplicates by snapshot — identical copies collapse into one row.
• timeline is event-centric — every capture event is its own row, even if the content repeats.

Quick examples

# best-first answer
clipmem recall "that command I copied" --format json --limit 5

# Safari today, token-efficient
clipmem recall --prefer-recent --app safari --hours 24 --format toon

# exact URL yesterday
clipmem recall "url" --has-url --hours 48 --format json

# chronological sweep, paginated
clipmem timeline --hours 24 --limit 25 --format json
clipmem timeline --hours 24 --limit 25 --cursor "<next_cursor>" --format json

# recover an image
clipmem get 42 --format json
clipmem export 42 --item 0 --uti public.png --out ./clipboard.png
clipmem export 42 --item 0 --uti public.png --out ./clipboard.png --force

Reading the response

Read these JSON fields first; walk nested items[].representations[] only after a get call:

• best_candidate.best_text — the flattened primary text.
• best_candidate.urls — URL array (empty when none).
• best_candidate.file_paths — file-URL array.
• why_selected, best_match_confidence, alternatives (only on recall).
• next_cursor, truncated — pagination state.
• schema_version — pin to 2 for stability.

Full schema in references/json-schema.md.

Troubleshooting

If recall looks empty or weak, widen --hours, drop source filters, or switch to timeline / search. For setup issues, sandbox PATH problems, or binary-only snapshots, see references/troubleshooting.md.
