Sillok

Sillok is a Rust CLI for meticulous agentic work chronicles. It records daily objectives, completed tasks, corrections, and retractions into a structured archive instead of a fragile append-only text log.

The name comes from Korean sillok, the court chronicles of Joseon. The design goal is similar: keep precise records of what happened, when, under what objective, and in what working context.

Status

Sillok is an early local-first CLI. The command interface is intended to be stable enough for agent harnesses. The live store is a private Turso/SQLite database and may gain new datashape versions over time.

Install

Build the binary in dev mode:

cargo build

Install it onto your PATH:

cargo install --path .

Then use:

sillok --help

Storage

By default, Sillok stores one user-global Turso/SQLite database at:

$XDG_DATA_HOME/sillok/sillok.db

If XDG_DATA_HOME is unset, it falls back to:

~/.local/share/sillok/sillok.db

Override the store with either:

sillok --store /path/to/sillok.db day
SILLOK_STORE=/path/to/sillok.db sillok day

The v2 store keeps append-only events plus indexed current projections in the database. Normal mutations insert a new event and update affected projection rows instead of loading and rewriting the whole chronicle.

Legacy v1 stores used a compressed private archive at sillok.slk.zst. Use sillok migrate --store /path/to/sillok.slk.zst --target /path/to/sillok.db --yes to create a v2 database. Migration always validates the legacy archive and creates a timestamped backup before activating the target.

Git sync is archive-based, not database-based. The configured remote stores one bitcode + zstd artifact, while every device keeps its own local SQLite/Turso projection database. Sync config is stored beside the selected store at <store>.sync.json.

Output

Quiet output is the default and is intended for agents. Successful write/action commands usually print nothing:

sillok note "Implemented archive-backed task logging"

Read commands still return compact JSON data without the response envelope. Use --json when an agent needs IDs or the full verbose response envelope:

{
  "ok": true,
  "command": "note",
  "generated_at": "2026-05-13T10:00:00+00:00",
  "ids": {},
  "data": {},
  "warnings": []
}

Failures are compact JSON by default:

{"error":"sync_remote_missing","message":"sync remote is not configured"}

Use --json for verbose failure envelopes:

{
  "ok": false,
  "command": "sync",
  "generated_at": "2026-05-13T10:00:00+00:00",
  "error": {
    "code": "sync_remote_missing",
    "message": "sync remote is not configured"
  }
}

JSON records include stable RFC3339 created_at and updated_at fields. Verbose success responses include ids, data, and warnings. Use --human for interactive summaries with local-device timestamps rendered as readable wall-clock time:

sillok --human day

Functionality

Sillok supports:

• Local-first event logging into a SQLite/Turso projection store.
• Daily task notes with status, tags, purpose text, and parent links.
• Day objectives that can be created and completed with notes.
• Amendments and retractions that preserve event history.
• Day summaries, record history lookup, filtered queries, and task trees.
• Archive integrity validation.
• JSON export of current visible records.
• Legacy v1 archive migration into the v2 store.
• Explicit destructive truncation with timestamped backup.
• Git-backed sync of the authoritative event stream as one compressed artifact.
• Backfilled timestamps and timezone-controlled day attribution.
• Runtime work-context capture including cwd and Git metadata when available.

Command Reference

Global options:

sillok --store /path/to/sillok.db <command>
sillok --human <command>
sillok --json <command>
sillok --at 2026-05-13T10:00:00Z <command>
sillok --tz America/Denver <command>

Global option details:

• --store: use a specific store path; defaults to SILLOK_STORE or XDG data storage.
• --human: print verbose readable summaries instead of quiet default output.
• --json: print the verbose JSON response envelope.
• --at: assign the event timestamp. Accepts RFC3339 or naive YYYY-MM-DDTHH:MM:SS.
• --tz: timezone for local day attribution and naive --at parsing.
• SILLOK_ACTOR: optional actor label recorded on new events; defaults to agent.

Initialize the archive if absent:

sillok init

Record a task or work note. Notes default to completed; use --status for open, active, blocked, or completed:

sillok note "Implemented timerange query indexing" --tags rust,sillok
sillok note "Investigating archive compaction" --status active --purpose "Reduce read latency"
sillok note "Split reducer from view indexing" --parent <record_id> --tags rust,indexing

note creates a task event. Without --parent, Sillok opens or reuses the day record for the event timestamp and links the task under that day. With --parent, the task is linked under an existing active record.

The status vocabulary is open, active, blocked, completed, and retracted. Prefer sillok retract when hiding a record so the retraction reason is preserved.

Manage day objectives:

sillok objective add "Finish archive indexing"
sillok objective add "Finish archive indexing" --tags rust,storage
sillok objective complete <objective_id> --note "All scoped work is complete"

Objectives are day-scoped records. Completing an objective changes its derived status to completed; an optional completion note is stored on the record.

Amend current derived state:

sillok amend <record_id> --text "Corrected task text"
sillok amend <record_id> --status completed
sillok amend <record_id> --purpose "Clarify why this work mattered"
sillok amend <record_id> --tags rust,indexing

amend records a new event and updates only the supplied fields in the current projection. It requires at least one changed field.

Retract a task or objective from current views:

sillok retract <record_id> --reason "Recorded against the wrong objective"

Retraction hides a task or objective from normal current views while preserving the underlying event history. Day records cannot be retracted.

Read records:

sillok show <record_id>
sillok day
sillok day --date 2026-05-13
sillok query --from 2026-05-13T00:00:00 --to 2026-05-13T23:59:59
sillok query --from 2026-05-13T00:00:00 --to 2026-05-13T23:59:59 --tag rust
sillok query --from 2026-05-13T00:00:00 --to 2026-05-13T23:59:59 --status completed
sillok query --from 2026-05-13T00:00:00 --to 2026-05-13T23:59:59 --context /home/cyh/project
sillok tree --root <record_id>
sillok tree --date 2026-05-13

Read command behavior:

• show returns one current record plus every event that references it.
• day returns the selected day's tree, objectives, and visible non-day records. Omit --date to use the current day in the selected timezone.
• query returns visible current records created in an inclusive time range. Filter by --context, --tag, or --status.
• tree renders the visible record tree rooted at --root, or at the selected day when --date is supplied.

Validate and export:

sillok doctor
sillok export json
sillok export json --from 2026-05-13T00:00:00 --to 2026-05-13T23:59:59

doctor validates SQLite integrity and replays persisted events to confirm the derived projection. export json returns visible current records; with --from and --to, export is limited to records created in that inclusive range.

Configure and run Git-backed event archive sync. Sync stores one bitcode + zstd level 22 archive artifact in the configured Git remote; the SQLite/Turso database remains local and is rebuilt from events when needed:

sillok sync remote set git@github.com:you/sillok-archive.git
sillok sync remote set /path/to/archive.git --branch main --path sillok.slk.zst
sillok sync remote show
sillok sync pull
sillok sync push
sillok sync run

Sync command behavior:

• sync remote set <URL> writes <store>.sync.json; defaults are branch main and artifact path sillok.slk.zst.
• sync remote show prints the configured URL, branch, artifact path, and sidecar path.
• sync pull reads the remote artifact, merges matching archives by event id, and rebuilds the local database when local state is missing, behind, or diverged.
• sync push fetches the remote artifact, merges matching archives by event id, rebuilds local state if needed, then writes the merged artifact to the configured remote.
• sync run performs bidirectional merge, validates the merged archive, rebuilds the local database with a backup if needed, then pushes.

Archives with the same archive_id are merged by event_id. Different non-empty archive IDs fail with sync_archive_mismatch and do not replace local or remote data. Git authentication is delegated to the user's existing git setup.

Migrate a legacy v1 archive:

sillok --store /path/to/sillok.slk.zst migrate --dry-run
sillok --store /path/to/sillok.slk.zst migrate --target /path/to/sillok.db --yes

migrate --dry-run validates the source archive and reports the migration plan. Writing a v2 target requires --yes. If --target is omitted, Sillok writes sillok.db beside the legacy archive.

Reset the archive only when an operator explicitly asks for a full reset. This creates a timestamped backup first:

sillok truncate --yes

truncate is destructive and requires --yes. It backs up the current v2 database, removes it, then initializes a fresh archive.

Backfill with explicit timestamps and timezone attribution:

sillok --tz Asia/Seoul --at 2026-05-13T21:30:00 note "Backfilled a late task"
sillok --at 2026-05-13T21:30:00+09:00 note "Backfilled a Seoul-time task"

RFC3339 timestamps keep their explicit offset. Naive timestamps are interpreted in the selected --tz, or in the system-local timezone when --tz is omitted.

Agent Integration

Add a short Sillok section to a repository AGENTS.md so coding agents record objectives and completed work while they operate:

## Sillok

Use Sillok for substantive agentic work. Record objectives, completed tasks,
and corrections during the session instead of relying on chat history. Quiet
output is the default for agents; use `--json` only when IDs or the full
response envelope are needed, and `--human` only for summaries intended for a
person.
Never run `sillok truncate --yes` unless the user explicitly asks to reset the
whole archive.

```bash
sillok objective add "Ship the storage/indexing refactor"
sillok note "Split reducer from view indexing" --parent <objective_id> --tags rust,sillok
sillok amend <record_id> --status completed
sillok note "Fixed relink regression coverage" --parent <objective_id> --tags tests
sillok show <record_id>
sillok query --from 2026-05-13T00:00:00 --to 2026-05-13T23:59:59 --tag rust
sillok objective complete <objective_id> --note "Scoped work is complete"
sillok day --human
```

Use `--at` for backfilled work and `--tz` when day attribution matters:

```bash
sillok --tz America/Denver --at 2026-05-13T16:45:00 note "Backfilled release notes" --tags docs
```

Development

Run checks:

cargo fmt
cargo clippy --all-targets --all-features
cargo test

Project constraints:

• No unwrap() or expect() in project source or tests.
• Keep modules under 300 lines where practical.
• Keep folder mod.rs files to module declarations only.
• Prefer explicit error handling and structured tracing.
• Do not treat the live database or legacy archive serialization as a public standard; use CLI export/migration commands for compatibility.
