What is utility-scripts?

A reference for ultrawork agents that explains how to use scripts for session, task, and project-context management.

Use it when an explorer, planner, worker, verifier, or reviewer needs to read or update ultrawork task and session information.

It provides consistent command patterns for retrieving task fields, session data, and context without handling these files incorrectly.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00052	$0.02694
Opus 5	$0.00026	$0.01347
Sonnet 5	$0.00010	$0.00539
Haiku 4.5	$0.00005	$0.00269

Measured 5d ago against content hash f6710c79261d, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-05, from the pricing page.

Security

Grade A, and why

utility-scripts scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Ultrawork Utility Scripts

IMPORTANT: Placeholder Notation

This document uses {SCRIPTS_PATH} and ${CLAUDE_SESSION_ID} as text placeholders that represent values provided in your agent prompt.

{SCRIPTS_PATH} → Replace with the actual SCRIPTS_PATH value from your prompt

${CLAUDE_SESSION_ID} → Replace with the actual CLAUDE_SESSION_ID value from your prompt

These are NOT bash environment variables (not $SCRIPTS_PATH or ${CLAUDE_SESSION_ID}). When you see bun "{SCRIPTS_PATH}/script.js", substitute the actual path like:
bun "/Users/name/.claude/plugins/.../src/scripts/script.js"

What is SCRIPTS_PATH?

SCRIPTS_PATH is the expanded absolute path to ultrawork scripts directory.

Your prompt includes it like this:

SCRIPTS_PATH: /Users/name/.claude/plugins/cache/hardworker-marketplace/ultrawork/0.26.0/src/scripts

Use {SCRIPTS_PATH} as a placeholder (substitute with actual value from your prompt) when calling Bun scripts in bash commands.

Session Management Scripts

Get Session Data

# Get full session JSON
bun "{SCRIPTS_PATH/session-get.js" --session ${CLAUDE_SESSION_ID}

# Get specific field (more efficient)
bun "{SCRIPTS_PATH/session-get.js" --session ${CLAUDE_SESSION_ID} --field phase
bun "{SCRIPTS_PATH/session-get.js" --session ${CLAUDE_SESSION_ID} --field goal
bun "{SCRIPTS_PATH/session-get.js" --session ${CLAUDE_SESSION_ID} --field working_dir

# Get session directory path (direct variable)
SESSION_DIR=~/.claude/ultrawork/sessions/${CLAUDE_SESSION_ID}

Update Session State

# Update session phase
bun "{SCRIPTS_PATH/session-update.js" --session ${CLAUDE_SESSION_ID} --phase EXECUTION
bun "{SCRIPTS_PATH/session-update.js" --session ${CLAUDE_SESSION_ID} --phase VERIFICATION
bun "{SCRIPTS_PATH/session-update.js" --session ${CLAUDE_SESSION_ID} --phase COMPLETE

# Mark plan approved
bun "{SCRIPTS_PATH/session-update.js" --session ${CLAUDE_SESSION_ID} --plan-approved

# Update exploration stage
bun "{SCRIPTS_PATH/session-update.js" --session ${CLAUDE_SESSION_ID} --exploration-stage complete

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
