--- name: microsoft/skillopt-sleep source: https://app.decimal.ai/s/microsoft-skillopt-sleep@4/SKILL.md source_sha256: 38080f8b87ea --- # SkillOpt-Sleep for Cursor SkillOpt-Sleep reviews recent local Cursor sessions, mines recurring tasks, replays those tasks, and proposes bounded improvements to a project Cursor skill. With the default gate enabled, a proposal is accepted only when it improves the held-out score. A normal run stages the proposal for review; nothing live changes until explicit adoption. There is no model-weight training. This plugin has no session-end hook and no MCP server. Run the cycle only when the user asks, or install a schedule only when the user explicitly requests one. ## Cursor target Always use this project-relative target for Cursor-visible learning: ```text .cursor/skills/skillopt-sleep-learned/SKILL.md ``` Pass it through `--target-skill-path` on `harvest`, `dry-run`, and `run`. Without an explicit target, the shared engine uses a Claude-managed skill under `~/.claude/skills`, which is not the intended Cursor project skill. The shared engine can also evolve project `CLAUDE.md`. If that secondary memory target is unwanted, set `"evolve_memory": false` in `~/.skillopt-sleep/config.json` before running. ## Choose the runner Use one of these supported command paths consistently: 1. Source checkout on macOS/Linux: `bash "$SKILLOPT_SLEEP_REPO/plugins/run-sleep.sh" ...` 2. Source checkout on Windows: `powershell -File "$env:SKILLOPT_SLEEP_REPO\plugins\run-sleep.ps1" ...` 3. Installed engine on any platform: `skillopt-sleep ...` If `SKILLOPT_SLEEP_REPO` is not set and `skillopt-sleep` is unavailable, stop and explain that the engine must be installed or a SkillOpt checkout must be selected. Do not substitute a hand-written edit for the engine workflow. ## Core workflow 1. **Harvest** local Cursor JSONL transcripts read-only. 2. **Mine** recurring, checkable task records from session digests. 3. **Replay** tasks under the current skill and memory through the selected backend. 4. **Reflect** on failures and propose bounded edits. 5. **Gate** the candidate on held-out real tasks. 6. **Stage** accepted proposals under `/.skillopt-sleep/staging//`. 7. **Adopt** only after review, backing up existing live targets first. ## Commands Use the installed-command form below, or replace `skillopt-sleep` with the platform-specific source runner described above. ```bash TARGET_SKILL=.cursor/skills/skillopt-sleep-learned/SKILL.md # Inspect current state and the latest staged proposal. skillopt-sleep status --project "$(pwd)" # Inspect mined tasks without provider spend. skillopt-sleep harvest --project "$(pwd)" --source cursor \ --target-skill-path "$TARGET_SKILL" --max-sessions 5 --max-tasks 3 # First smoke check: deterministic and no provider calls. skillopt-sleep dry-run --project "$(pwd)" --source cursor --backend mock \ --target-skill-path "$TARGET_SKILL" --max-sessions 5 --max-tasks 3 --json # Model-driven optimization through the authenticated Cursor Agent CLI. skillopt-sleep run --project "$(pwd)" --source cursor --backend cursor \ --target-skill-path "$TARGET_SKILL" \ --max-sessions 5 --max-tasks 3 --progress # Apply the latest accepted staged proposal after review. skillopt-sleep adopt --project "$(pwd)" ``` Actions are `status`, `harvest`, `dry-run`, `run`, `adopt`, `schedule`, and `unschedule`. - Default backend is `mock`, which is deterministic and makes no provider calls. - `--backend cursor` uses the user's authenticated Cursor Agent CLI budget for model-driven mining, replay, judging, and reflection. - `--source cursor` reads `~/.cursor/projects//agent-transcripts/*/*.jsonl`. - `--cursor-home PATH` overrides the Cursor home used for harvesting. - `--scope invoked` selects the current workspace; `--scope all` includes every Cursor workspace. - `--cursor-path PATH` or `SKILLOPT_SLEEP_CURSOR_PATH` selects a non-default `cursor-agent` executable. - `--model NAME` or `SKILLOPT_SLEEP_CURSOR_MODEL` overrides the Cursor model. - Check model identifiers with `cursor-agent --list-models`; when cost matters, verify the billed variant in Cursor's usage reporting. - Keep live runs bounded with `--max-sessions`, `--max-tasks`, and `--progress`. - A held-out gain is evidence for that run, not a promise of general improvement. The first harvest uses a 72-hour lookback. Use `--lookback-hours N` for a wider initial window or `--lookback-hours 0` for all available history. A stateful `run`, including a no-task run, records a harvest checkpoint; later runs use the checkpoint rather than the initial lookback. Inspect counts with `harvest` or `dry-run` before the first real run because those actions do not advance state. Available backends are: - `mock` - deterministic, with no provider calls (default); - `cursor` - the authenticated Cursor Agent CLI; - `claude` - the authenticated Claude CLI; - `codex` - the authenticated Codex CLI; - `copilot` - the authenticated GitHub Copilot CLI; - `handoff` - prompt/answer files for an interactive agent session; - `azure_openai` - the configured Azure OpenAI endpoint. SkillOpt reads the target skill and inserts its text into replay prompts; it does not invoke the file as a native Cursor skill. Ordinary Cursor backend calls run in a new empty temporary workspace in read-only Ask mode. File reads, file writes, and MCP tools are denied. `--project` controls harvesting, target files, state, and staging; it is not the Cursor Agent execution workspace. Cursor tool-aware replay is temporarily disabled pending live Cursor permission-boundary validation. A task containing a `tool_called` check fails nonzero before Agent mode starts. The failed replay does not add a cache entry, stage, adopt, persist state, or advance the harvest checkpoint. Use another backend for those tasks. Do not claim that repository- or tool-dependent behavior was validated. The current engine does not implement a fresh-worktree replay for Cursor. A real-backend `dry-run` still makes provider calls; it only suppresses staging. Session and task limits are workload bounds, not hard limits on calls, tokens, time, or money. Start with small limits. ## Reviewable data path Cursor harvesting retains user/assistant text, tool names, and explicit turn errors while excluding raw tool arguments, tool outputs, and non-message records. Known secret-shaped strings are redacted, but pattern-based redaction cannot guarantee that a transcript is safe to send to a provider. For sensitive sessions, export tasks before any real-backend replay: ```bash TARGET_SKILL=.cursor/skills/skillopt-sleep-learned/SKILL.md skillopt-sleep harvest --project "$(pwd)" --source cursor \ --target-skill-path "$TARGET_SKILL" \ --max-sessions 5 --max-tasks 3 --output reviewed-tasks.json ``` Inspect and redact the file, then set its top-level `"reviewed"` field to `true`. Only then run: ```bash skillopt-sleep dry-run --project "$(pwd)" --backend cursor \ --tasks-file reviewed-tasks.json --progress --json ``` Real backends reject task files that remain unreviewed. Never include raw transcripts, credentials, secrets, or sensitive task content in messages, commits, or generated summaries. ## Scheduling Scheduling is opt-in. The scheduler persists project, backend, time, and the optional auto-adopt flag, but not `--source`, Cursor path/home/model overrides, or `--target-skill-path`. Before scheduling a Cursor cycle, set at least these values in `~/.skillopt-sleep/config.json`: ```json { "transcript_source": "cursor", "target_skill_path": ".cursor/skills/skillopt-sleep-learned/SKILL.md", "backend": "cursor" } ``` Then run: ```bash skillopt-sleep schedule --project "$(pwd)" --backend cursor --hour 3 --minute 17 skillopt-sleep unschedule --project "$(pwd)" ``` The scheduler uses cron on Unix and Task Scheduler on Windows. Scheduled runs stage proposals by default. Use `--auto-adopt` only when the user has explicitly requested unattended adoption. ## Report results For `dry-run` and `run`, report: - session and task counts; - held-out baseline and candidate scores; - gate action and accepted/rejected edit counts; - exact proposed edits; - staging directory, when one was created. Read staged `report.md` before summarizing a run. Offer adoption only after the user reviews an accepted proposal that is still staged. Never claim broad improvement from one run. ## Hard rules - Harvest is read-only. Never edit Cursor transcript files. - Never hand-edit the target skill or `CLAUDE.md` as a substitute for adoption. - Do not run a real backend on sensitive content without confirming its data boundary or using the reviewed-task workflow. - Do not add a session-end hook or imply that installing this plugin schedules anything. - Show validation evidence before recommending adoption. - Treat generated edits as proposals, not as source of truth.
