util-0-v2-handover

util-0-v2-handover is a skill for Claude Code, Codex from jakkaj/tools. It costs 27 tokens per session (3,460 once invoked), scanned A, original, MIT.

A session handover writer for coding agents. It summarizes remembered conversation and code context so another agent can continue, optionally within a specific domain.

In plain words
What is it for?
Creating short continuation notes with status, references, file paths, and pending work. It is useful when transferring an unfinished coding task to another agent.
Why use it?
It reduces repeated explanations when work moves between agents or a session is compacted. Unknown details are marked clearly instead of being guessed.

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.

Security

Grade A, and why

util-0-v2-handover 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 9d 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.

The opening of the file, as written. The whole thing — 277 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Please deep think / ultrathink as this is a complex task.

util-0-v2-handover

A conversation+code compaction handover that another LLM can paste in and resume immediately. V2 adds optional domain context so the receiving agent understands domain boundaries, ownership, and contracts.

CLI /util-0-v2-handover --plan "" # optional; used only for pointers/anchors --phase "" # optional; defaults to current/latest --format "compact|lean|json" # default: compact --max 1400 # token cap (default 1400; hard stop 1600) --domain "" # optional; scope handover to a specific domain

Hard Rules

Memory only: Do not open files or call tools. Summarize from session memory.

No scaffolding noise: No “Read…”, “Working…”, diffs, mermaid, stack traces, or step logs.

Pointers, not payloads: If a detail isn’t remembered, write ? and add a pointer in Refs (plan §/dossier/log).

Status tokens: [ ] pending, [~] in‑progress, [x] complete, [!] blocked.

Context protection: Obey strict caps; keep strings short (≤12 words) and lists Top‑N only.

Deterministic: Natural sort for IDs; consistent key order.

Entity preservation: File paths, function names, task IDs, decision IDs, and CLI commands MUST be preserved VERBATIM. Never paraphrase these — copy exactly or write “?”.

Two‑Stage Generation (single response)

Internal consolidation (silent): Think forward — what will the receiving agent need to DO next?

  1. Ask: “What 5 questions will the next agent ask in their first 30 seconds?”
  2. Recover: user’s explicit requests (quote key lines), decisions + rationale, code state, failed attempts, and blockers that answer those questions.
  3. Identify ≤5 immutable facts and ≤3 verbatim user constraints for the anchors section.

Emit summary: Output one artifact in the requested format using the schema below. If near --max, drop lowest‑priority sections in the Trim Order.

Output Formats A) --format compact (default; tight and skimmable)

HOVR/2 microformat with short keys and capped lists. One fenced block; no extra text.

HOVR/2 m:{ts:"", plan:"<path or ?>", phase:"", feat:"<slug or ?>", prog:"<x/y or %>", domain:"<slug or ? — optional>"}

intent:{ primary:"", quotes:["", ...≤2], scope:["<in/out of scope>", ...≤3] }

tasks:{ done:[ids…≤8], ip:[ids…≤5], pend:[ids…≤10], blk:[["",""], ...≤3], critdeps:[["T033","T032"], ...≤5] }

tests:{unit:"pass|fail|mixed|?", integ:"pass|fail|mixed|?", cov:"<%|?>", notes:"<≤80 chars>"}

risks:[["", "", "", "<domain — optional>"], ...≤5]

refs:{plan:" §<anchor|?>", tasks_file:"<absolute-path-to-tasks.md|?>", log:"<.../execution.log.md|?>", paths:["<key dir/file>", ...≤5]}

Trim Order (when hitting --max): code.hot → code.domain_dirs → fails → risks → concepts.keys → decisions.other → tasks.pend → code.files → tests.notes → refs.paths → anchors.immutable. Never trim: m, intent.primary, timeline.just_completed, timeline.current, next (including next.tasks_file), m.domain (when present), anchors.user_verbatim.

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.

util-0-v2-handover is a skill published in the GitHub repository jakkaj/tools (5 stars, last pushed 23d ago), licensed MIT. It adds 27 tokens to every session and 3,460 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
