squid-implement-task

squid-implement-task is a skill for Claude Code from iusztinpaul/squid. It costs 75 tokens per session (1,398 once invoked), scanned A, original, Apache-2.0.

A command for implementing one or more approved software tasks through a repeated developer-and-tester process. It coordinates other agents, waits for tests to pass, and commits each completed task.

In plain words
What is it for?
Use it for ready-to-build tasks, task lists, or approved task plans, including work referenced by an issue number or task file. It first checks the project instructions and then manages the implementation and testing loop.
Why use it?
It adds a testing checkpoint before each task is marked complete and keeps implementation work tied to tracked task files or references. It also separates planning from the actual build work.

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

squid-implement-task 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 today.

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 — 109 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Implement Task — inner SWE↔Tester loop (1 or N tasks)

Take a task (or a list of tasks / an approved Tasks Plan) and drive each one through the inner SWE → Tester loop, committing each task once it passes. Runs in whatever working tree it's invoked in — the feature worktree when /squid-implement-night invokes it (pass Working directory: {path} to every agent), your current branch when standalone. No worktrees are created here (that's /squid-plan's job) and no human gates run here (those live in /squid-plan and at the end of /squid-implement-night).

$ARGUMENTS is one of: a single task ref (NNN-slug / #N), a free-form task description, the feature's pending task files (tasks/<NNN>-*.md, status: pending), or several refs. If empty, ask the human what to implement.

You are the orchestrator — a MANAGER, not an implementer. You launch agents, enforce the Tester gate, and commit on green. You do NOT write code, run tests, or review the diff yourself beyond inspection (git diff, git log).

Read AGENTS.md first to confirm the active tracker mode (file or gh) and the project's stack + test commands.

Critical rules:

  • Never rubber-stamp the Tester. Spot-check that each AC marked PASS has real evidence (test name, file:line, command output) and that the e2e adversarial section actually attempted break paths. Re-launch with concrete feedback if not.
  • One agent per task. Never bundle multiple tasks into one agent call.
  • Commit each task on PASS — do NOT push. Pushing, PR creation, acceptance, and review are /squid-review's job.

Step 1 — Resolve the task list

Build an ordered list of tasks from $ARGUMENTS:

  • Tracker ref(s) (NNN-slug / #N) → load each task's tasks/<NNN>-<slug>.md.
  • Approved Tasks Plan → the feature's tasks/<NNN>-*.md files with status: pending, in NNN order (gh mode: the feature's open issues).
  • Free-form description → a single ephemeral task; don't create a task file unless the human asks.
  • Empty → ask the human what to implement.
