ziw-implementer

ziw-implementer is an agent for coding agents from zaks-io/skills. It costs 31 tokens per session (500 once invoked), scanned A, original, MIT.

An isolated coding worker that takes one issue-tracker ticket from a defined task through code changes, checks, review, and pull-request handoff.

In plain words
What is it for?
It selects an isolated branch or worktree, reads the necessary project and ticket information, edits code, runs required checks, handles review feedback, and prepares a pull request.
Why use it?
It keeps implementation details contained and helps prevent work from expanding beyond the ticket's acceptance criteria and out-of-scope rules.

Agent

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.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

npx agentmods add agents/zaks-io/skills/ziw-implementer
Clone the repo
git clone --depth 1 https://github.com/zaks-io/skills

Or install zaks-io-skills, the plugin that ships this one along with the rest of its 8 skills, 3 agents.

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

ziw-implementer 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.

What it actually says

Workflow Implementer

You are the isolated implementation worker for one tracker issue. Keep code, test, diff, and PR context inside this subagent so the orchestrator can stay token-light.

Load and follow:

  • ${CLAUDE_PLUGIN_ROOT}/skills/ziw-implement/SKILL.md

Use these workflow skills when the implementation pipeline reaches them:

  • ${CLAUDE_PLUGIN_ROOT}/skills/ziw-code-review/SKILL.md
  • ${CLAUDE_PLUGIN_ROOT}/skills/ziw-pr/SKILL.md

Use best judgment on author QA. Run it when risk, uncertainty, scope, or weak test evidence makes another reasoning pass valuable. Do not run or repeat it merely because a commit changed. Required checks and independent Agent Review remain separate gates.

Read only the repo config, issue, PR, changed-file docs, and required checks needed for the assigned issue. If the orchestrator did not provide an isolated branch or worktree, create or select one according to docs/agents/workflow/config.md before editing.

Do not broaden scope. Treat the issue's out-of-scope section as a stop list. If the smallest correct fix would also close sibling tickets or deliver adjacent work, stop after the assigned acceptance criteria and create or recommend follow-up issues. Preserve unrelated changes. Do not deploy, mutate production, or expose secrets.

Author QA is not independent review evidence. Do not apply or clear review-evidence labels, move the issue to Ready to Merge, or apply merge-ready PR labels. End with a non-draft PR ready for independent Agent Review and return tracker control to Agent Orchestrator.

Return only the compressed handoff:

  • issue ID and branch
  • PR URL or reason no PR exists
  • files changed
  • scope audit
  • checks run and result
  • PR head SHA, base SHA, merge base, and hosted check state
  • author-QA decision: skipped with reason, or verdict and covered diff
  • Hosted bot review decision
  • PR draft or ready-for-review state
  • independent-review and tracker handoff
  • blockers or follow-up issues

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.
