# Ultracontinue Local v1.0

Zero-friction multi-session resumption. In a fresh Claude Code session, type
`/ultracontinue` — the command reads the per-project state file
(`.claude/projects/<project>/.session-state.local.json`), shows a 3-line summary,
and immediately begins executing the next session.

The state file is the contract. Any session-end mechanism may write it
(`/ultraexecute-local` Phase 8 / Phase 2.55 / Phase 4, the
`/ultraplan-end-session-local` helper, or — in the future — `graceful-handoff`).
This command only reads.

Pipeline position:

```
/ultraplan-local           →  plan.md
/ultraexecute-local        →  progress.json + .session-state.local.json
... session boundary, fresh chat ...
/ultracontinue             →  reads .session-state.local.json, starts next session
```

See **Handover 7** in `docs/HANDOVER-CONTRACTS.md` for the full schema.

## Phase 0 — `--help` handling

Parse `$ARGUMENTS` with `parseArgs($ARGUMENTS, 'ultracontinue')` from
`lib/parsers/arg-parser.mjs`. Dispatch the usage block ONLY when one of these
two conditions equals exactly true (no substring search, no "contains" check):

- `flags['--help'] === true`, OR
- `positional[0] === '-h'` (single-dash short form — the parser keeps it as
  positional because the schema does not declare an alias).

In every other case — including when `$ARGUMENTS` is empty, whitespace-only,
the literal empty string `""`, or a positional project-dir — fall through to
Phase 1. Do NOT print the usage block on empty args.

```
/ultracontinue — Resume the next session in a multi-session ultraplan project.

Usage:
  /ultracontinue                  # auto-discover state file under cwd
  /ultracontinue <project-dir>    # explicit project directory
  /ultracontinue --help           # this message

Reads .claude/projects/<project>/.session-state.local.json (per-project,
gitignored). On a valid resumable state, prints a 3-line summary and begins
executing the next session immediately. No interactive confirmation prompt.

State-file schema (v1):
  schema_version           1
  project                  string
  next_session_brief_path  string (validator soft-checks file existence)
  next_session_label       string
  status                   in_progress | partial | failed | stopped | completed
                           (completed → no further sessions to resume)
  updated_at               ISO-8601 timestamp
  (unknown top-level keys are tolerated — forward-compat for graceful-handoff v2.2)

Typical flow:
  /ultrabrief-local                # produces brief.md
  /ultraplan-local --project ...   # produces plan.md
  /ultraexecute-local --project .. # writes session-state on session-end
  ... (fresh Claude chat) ...
  /ultracontinue                   # reads session-state, runs next session
```

## Phase 1 — Resolve project directory

The parsed `positional[0]` from Phase 0 is the explicit project-dir argument,
when present. Otherwise (empty `$ARGUMENTS` or whitespace-only) auto-discover.

### Step 1.a — Reject `.md` positional argument (SC-2)

If `positional[0]` is non-empty AND ends in `.md`, the user almost certainly
pasted a `NEXT-SESSION-PROMPT.local.md` path instead of a project directory.
Print the following diagnostic to stderr and exit non-zero. Do NOT proceed.

```
Error: expected <project-dir>, got a markdown file path: <positional[0]>
Did you mean to paste the file path as a project directory?
Usage: /ultracontinue-local <project-dir>
```

### Step 1.b — Auto-discover candidates

When no explicit project-dir was given, enumerate
`.claude/projects/*/.session-state.local.json` paths with `node -e`
(NOT shell glob — harness-mode safety) and emit each as one JSON line of
`{"path": ..., "updated_at": ...}` so Phase 1 can sort numerically:

```bash
!`node -e "const fs=require('fs'),path=require('path');const root='.claude/projects';if(!fs.existsSync(root))process.exit(0);for(const d of fs.readdirSync(root)){const p=path.join(root,d,'.session-state.local.json');if(!fs.existsSync(p))continue;let u='';try{u=(JSON.parse(fs.readFileSync(p,'utf8'))||{}).updated_at||''}catch(_){};process.stdout.write(JSON.stringify({path:p,updated_at:u})+'\\n');}"`
```

Sort the emitted candidates by `Date.parse(updated_at)` descending (newest
first) — numeric comparison, NOT lexicographic string compare. The newest
resumable state wins.

### Step 1.c — Decision tree

- **0 candidates and no explicit arg:** print SC-2 cold-start message and exit:
  ```
  No active multi-session project here.
  Start with /ultrabrief-local or /ultraplan-local.
  ```
- **1 candidate (or explicit non-`.md` arg):** continue to Phase 2 with that path.
- **>1 candidates and no explicit arg:** with the Date.parse sort applied, the
  newest resumable state wins automatically and the command continues to Phase 2
  with that path. (Operators who want a different candidate re-invoke as
  `/ultracontinue <project-dir>`.)

## Phase 2 — Validate the state file

Run the validator from a Bash invocation:

```bash
!`node lib/validators/session-state-validator.mjs --json {state-file-path}`
```

Interpret the result:

- **Validator exit code != 0 OR `valid: false` in JSON output:** print the
  structured `errors[]` (each `[code] message` on its own line) and exit. Do not
  proceed to narration. Suggest running the validator directly for follow-up:
  `node lib/validators/session-state-validator.mjs <path>`.
- **`valid: true` AND any warning has `code: SESSION_STATE_NOT_RESUMABLE`** (i.e.
  `status: completed`): print "no further sessions to resume; project complete"
  and exit cleanly.
- **`valid: true` AND status is one of `in_progress | partial | failed | stopped`:**
  proceed to Phase 3.

## Phase 3 — Narrate 3-line summary

Print this exact template (using values from the validated `parsed` object):

```
Project: {project}
Next session: {next_session_label}
Brief: {next_session_brief_path}
```

No interactive confirmation prompt — per the brief NFR ("ingen prompts, men la
informasjon synes"). The 3-line block is informational only.

## Phase 4 — Begin execution

Read the file at `next_session_brief_path` (it is the brief that the next
session is supposed to execute — typically the same `brief.md` for
single-brief multi-session plans, or a session-specific spec for parallel
session decomposition). Understand the task and begin executing per the
standard ultraplan-local pipeline. The user did not type a separate "start"
command — `/ultracontinue` is the start.

If the brief file does not exist (validator emits a warning but does not
fail), print: `Warning: next_session_brief_path "{path}" does not exist on
disk. Cannot continue automatically.` and exit. Do not guess.

## Phase 5 — Stats tracking

Append a one-line JSON record to `${CLAUDE_PLUGIN_DATA}/ultracontinue-stats.jsonl`
if the env var is set; silently skip otherwise.

```json
{"ts":"<iso-8601>","project":"<project>","next_session_label":"<label>","status":"<status>"}
```

## Hard rules

- **Idempotent.** Running `/ultracontinue` twice in the same Claude session
  does not advance state — the writer (Phase 8 / hook / helper) advances state
  only when a session completes.
- **Zero secrets in the state file.** Status, paths, labels — never API keys,
  never user content beyond filenames.
- **NEVER auto-load via SessionStart.** The command is operator-invoked only.
  Auto-loading would re-introduce the stale-file risk noted in
  `feedback_next_session_prompt_manual.md`.
- **No interactive prompts.** Phases 0–4 must run without `AskUserQuestion`.
  This keeps the command headless-safe.
