ZCode Large Task Fixture

Use this skill to create a large local task that behaves like a long-running ZCode Agent task. It writes both persistence layers:

App task index: ~/.zcode/v2/tasks-index.sqlite
Agent session DB: ~/.zcode/cli/db/db.sqlite

The generated task is synthetic test data. Always back up before writing and record the manifest path.

Quick Commands

From the z-code repository root:

node .agents/skills/zcode-large-task-fixture/scripts/generate-large-task-fixture.mjs \
  --workspace "$PWD" \
  --turns 3000

Verify an existing generated task:

node .agents/skills/zcode-large-task-fixture/scripts/generate-large-task-fixture.mjs \
  --verify sess_perf_large_YYYYMMDDHHMMSS_xxxxxxxx

Remove a generated task:

node .agents/skills/zcode-large-task-fixture/scripts/generate-large-task-fixture.mjs \
  --delete sess_perf_large_YYYYMMDDHHMMSS_xxxxxxxx

Workflow

Confirm the target workspace path. Use the repository root unless the user names another workspace.
Generate with --turns 3000 for a large fixture. This creates roughly 6,000 messages and 20,000 parts.
Read the script output and report the sessionId, manifest path, counts, and backup directory.
Verify with --verify <sessionId>.
Tell the user to restart or refresh the app if it was already running, then open the pinned task titled Performance Fixture Large Mixed Task.

Safety

The script uses SQLite .backup before generation unless --no-backup is passed.
Backups are stored under ~/.zcode/perf-task-backups/<timestamp>/.
Manifests are stored under ~/.zcode/perf-task-manifests/<sessionId>.json.
Use --delete <sessionId> for generated fixtures. It deletes from tasks-index.sqlite and cascades the agent session rows.
Do not delete manually unless you have checked the manifest and confirmed the task id starts with sess_perf_large_.

Coverage

Generated sessions include:

User text and file parts
Assistant text and reasoning parts
Tool parts with completed, running, pending, and error states
Bash, Read, Grep, Glob, Edit, Write, TodoWrite, AskUserQuestion, Agent, WebSearch, and WebFetch tool shapes
Patch, compaction, subtask, agent, retry, step-start, and step-finish parts
Todo rows, session target rows, model usage rows, turn usage rows, and task index searchable text
