delivery-tick

delivery-tick is a skill for Claude Code, Codex from blakemartz/delivery-loop. It costs 98 tokens per session (1,870 once invoked), scanned A, original, MIT.

A single step in an automated software-delivery workflow that checks the work board and starts or reviews one ready piece of work. It can optionally handle several independent actions at once.

In plain words
What is it for?
Use it to patch rejected changes, review pending changes, or start the next ready task. It can also be configured to merge changes automatically.
Why use it?
It keeps development work moving in a controlled order and limits how many changes happen during one cycle.

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

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

delivery-tick 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 3d 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.

How it starts

The opening of the file, as written. The whole thing — 42 lines — stays where its author put it; the contents beside it link to each section on GitHub.

delivery-tick — one tick of the orchestrator loop

You are the orchestrator from the delivery spec (${CLAUDE_PLUGIN_ROOT}/docs/agentic_delivery_spec.md, §3.1, §6). You dispatch; you never implement or review yourself. You never merge either — unless --auto-merge is set, which enables exactly one gated exception (the Auto-merge step below) and nothing more.

Dispatch each role by spawning an agent (Agent tool) whose prompt names the plugin skill, e.g. "Run the /delivery-loop:next-task skill on issue #." Read .claude/delivery.conf for BASE_BRANCH.

Mode

Parse the argument first:

  • Serial (default — no argument): take the FIRST matching action from the tick below, dispatch it, then stop — one state transition per tick keeps /loop pacing meaningful. The in-flight cap for starts stays 2.
  • Parallel (--parallel N, e.g. --parallel 3): parse N defensively — bare --parallel or any value that is not a whole number means 3; anything above 16 clamps to 16; --parallel 1 or lower falls back to serial mode. For N ≥ 2: walk ALL the tick steps, collecting every matching action in the same priority order, filter to an independent batch (rules below), truncate to N actions, and spawn every agent in a single message so they run concurrently. Then WAIT for the entire batch and report each agent's outcome — the tick does not end until every agent returns. That synchronous barrier is what makes /loop /delivery-tick --parallel N safe: two batches can never overlap. N doubles as the in-flight ceiling for starts.
  • Auto-merge (--auto-merge, off by default): an independent flag that composes with either mode — parse it separately from --parallel/N, in any order. When set, the tick runs the Auto-merge step (step 1) before any dispatch, squash-merging every agent PR that is fully approved, mergeable, and green. When absent (the default) that step is skipped and approved+mergeable PRs remain the human's queue — you never merge. The flag flows through /loop verbatim.

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.

delivery-tick is a skill published in the GitHub repository blakemartz/delivery-loop (4 stars, last pushed 1mo ago), licensed MIT. It adds 98 tokens to every session and 1,870 once invoked, about $0.0005 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.
