gdd-state

name	gdd-state
description	Query, recover, or roll back the Phase 57 SQLite state backbone. Use when you need to inspect the decisions/blockers/plans tables with a raw SELECT, rebuild a corrupt state.sqlite from the markdown STATE.md, or revert to the markdown-only source of truth by removing state.sqlite. Activates for requests involving querying the SQLite state database, recovering from SQLite corruption, or reverting the migration (demigrate).

/gdd:state

The Phase 57 SQLite state backbone is opt-in (--migrate-state) and fully reversible. Markdown .design/STATE.md is always the human-editable SoT; SQLite is a faster query layer derived from it. This skill exposes three subcommands for operating on that layer.

Subcommands

Subcommand	What it does
/gdd:state query "<sql>"	Run a read-only SELECT against .design/state.sqlite.
/gdd:state recover	Rotate the current sqlite to a .bak and rebuild from markdown.
/gdd:state demigrate	Remove .design/state.sqlite; markdown becomes the SoT again.

---

query

Execute a read-only SELECT against the state database.

The engine opens the file with readonly:true so all writes are rejected at the engine level. A first-token denylist (Set membership, no regex) additionally blocks DROP, DELETE, UPDATE, INSERT, ALTER, ATTACH, CREATE, PRAGMA, VACUUM, ANALYZE, REINDEX, and REPLACE before the connection is opened.

node -e '
  const qs = require("./scripts/lib/state/query-surface.cjs");
  const result = qs.query(process.argv[1], { projectRoot: process.cwd() });
  console.log(JSON.stringify(result, null, 2));
' "<sql>"

Outputs { rows: [...], backend: "sqlite" } on success, or { degraded: true, message: "..." } when SQLite is not active.

Degrades gracefully (no throw) when BACKEND==='markdown' or when .design/state.sqlite has not been created yet (run --migrate-state first).

---

recover

Rotate the current (possibly corrupt) .design/state.sqlite to .bak.0, then rebuild a fresh database from the markdown .design/STATE.md using migrate-to-sqlite.cjs in force mode. Runs PRAGMA integrity_check on the result and reports the outcome.

node -e '
  const qs = require("./scripts/lib/state/query-surface.cjs");
  const result = qs.recover({ projectRoot: process.cwd() });
  console.log(JSON.stringify(result, null, 2));
'

Outputs { recovered: true, integrity: true, message: "..." } on success.

Backup rotation keeps at most 10 files (.bak.0 through .bak.9). The oldest backup is overwritten when the cap is reached.

---

demigrate

Remove .design/state.sqlite so the markdown STATE.md becomes the SoT again. Idempotent: if the file does not exist, returns a clear no-op message without error. A backup is taken in .bak.0 before removal.

node -e '
  const qs = require("./scripts/lib/state/query-surface.cjs");
  const result = qs.demigrate({ projectRoot: process.cwd() });
  console.log(JSON.stringify(result, null, 2));
'

Outputs { demigrated: true, message: "..." } when the file was removed, or { demigrated: false, message: "..." } when it was already absent (no-op).

To re-enable SQLite after a demigrate, run --migrate-state again.

Key design decisions

• Markdown is always the SoT. SQLite is opt-in via --migrate-state and reversible via demigrate. The markdown file is never silently overwritten.
• Read-only queries only. The query subcommand enforces SELECT-only via both the engine (readonly:true) and a defense-in-depth denylist. No writes are possible through this skill.
• Backup rotation cap. rotateBak shifts .bak.0..8 up by one index and caps at .bak.9 (10 files total). The oldest backup is overwritten automatically.
• Graceful degradation. All subcommands return a clear { degraded, message } object (no throw) when better-sqlite3 is not installed or when GDD_STATE_BACKEND=markdown is set.
