squid-implement-nightRun the full agent-team pipeline end-to-end for one feature whose Tasks Plan is already approved by /squid-plan, handing the human a validated, ready-to-squash-merge PR.
Squid Implement Night is an agent skill from iusztinpaul/squid. Run the full agent-team pipeline end-to-end for one feature whose Tasks Plan is already approved by /squid-plan, handing the human a validated, ready-to-squash-merge PR. Trigger after /squid-plan.
Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The licence is Apache-2.0.
4 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit f5bf6b3. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Shell commands in SKILL.md call:
gitFrom the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Squid Implement Night loads about 1.2k tokens when it runs. Until then it costs about 55 tokens; SKILL.md has 523 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

.claude/skills/squid-implement-night/SKILL.md (or your agent's skills folder).Build an already-approved feature plan all the way to a validated, ready-to-merge PR. This skill is a thin orchestrator: the real work lives in the sub-skills it invokes — /squid-implement-task, /squid-review, /squid-review-ci — plus the agents those skills launch.
$ARGUMENTS is the approved Tasks Plan reference (path or feature slug) produced by /squid-plan. If empty, ask the human which plan to build (and remind them to run /squid-plan first if none exists).
You are the orchestrator — a MANAGER. You sequence the sub-skills, route rollback tasks, and enforce the gates. You do NOT write code, review the diff, or run tests yourself.
Read AGENTS.md first (tracker mode, the pipeline map, and the cross-cutting rules). Retry caps live in each sub-skill.
Input: an approved Tasks Plan + the feature branch/worktree /squid-plan created.
Output: a CI-validated feature PR, ready for the human to squash-merge.
The pipeline blocks on the human only at the very end (squash-merge). (Plan approval already happened in /squid-plan.) Everything between is automated; failures route back into /squid-implement-task as rollup tasks rather than stopping the pipeline. Caps stop the pipeline: Tester FAIL 5/task, PA REJECT 3, PR-Reviewer 3, On-Call 5 — when a cap fires, surface USER ACTION REQUIRED and stop.
Critical rules:
/squid-review reports "no blockers" or /squid-review-ci reports "green", confirm the evidence is real before advancing./squid-implement-task, /squid-review, /squid-review-ci by their skill names so it works when installed as a plugin./squid-plan created the feature branch feat/{slug} — either in a dedicated worktree at ../{repo}-{slug} or in the current working tree — and wrote the feature's task files (tasks/<NNN>-*.md, status: pending) on it. Find where that branch is checked out:
git worktree list # find the working tree whose branch is feat/{slug}Confirm that working tree exists and contains pending task files (tasks/<NNN>-*.md with status: pending); WORKTREE_PATH is its path (the dedicated worktree, or the repo root if the branch lives in the current tree). If there's no matching branch or no pending tasks, stop and tell the human to run /squid-plan first. Pass Working directory: {WORKTREE_PATH} to every sub-skill / agent so all work happens there.
Invoke /squid-implement-task once with the feature's pending tasks. It loops over every task — SWE → Tester → commit on PASS → next. (Do NOT loop here yourself; the per-task iteration lives inside /squid-implement-task.)
invoke /squid-implement-task with: the feature's pending tasks (tasks/<NNN>-*.md, status: pending), Working directory: {WORKTREE_PATH}invoke /squid-review with: feature {title}, Working directory: {WORKTREE_PATH}/squid-review pushes, creates/updates the PR, and runs PA acceptance then PR-Reviewer.
/squid-implement-task on that one rollup task (it builds + commits the fix), then re-invoke /squid-review. Repeat.invoke /squid-review-ci with: PR #{N}, Working directory: {WORKTREE_PATH}/squid-review-ci watches CI and drives it green (On-Call diagnoses → SWE fixes → re-check).
The validated PR is ready. The orchestrator does NOT squash — per-task commits stay on the branch; the human uses GitHub's "Squash and merge".
Report the final summary:
## /squid-implement-night complete — {Feature title}
**PR:** {URL} (validated; ready to squash-merge)
**Branch:** feat/{slug} ({N} per-task commits)
**Worktree:** {WORKTREE_PATH}
**Tasks delivered ({N}):** {table — Tester / PA accept / PR-Reviewer / CI}
**Rollup tasks ({M}):** {list, or "none"}
Next: review the PR, then GitHub's **Squash and merge**. Remove the worktree with `git worktree remove {WORKTREE_PATH}` after merge./squid-implement-night ends here.
/squid-review-ci handles its own CI fixes internally and does not re-enter /squid-review.© iusztinpaul, Apache-2.0. Rendered from Markdown: HTML in the file is shown as text, images as links, and headings moved down two levels. Raw file

Squid Implement Night fits situations like: after /squid-plan; tasks that involve End-to-end testing.
Run `npx skills add iusztinpaul/squid --skill squid-implement-night -a claude-code`. Or copy the skill folder (skills/squid-implement-night in iusztinpaul/squid) into .claude/skills/squid-implement-night in your project. Claude Code loads it when a task matches its description.
Run `npx skills add iusztinpaul/squid --skill squid-implement-night -a codex`. Or copy the skill folder (skills/squid-implement-night in iusztinpaul/squid) into .agents/skills/squid-implement-night in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add iusztinpaul/squid --skill squid-implement-night -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/squid-implement-night, .gemini/skills/squid-implement-night, .github/skills/squid-implement-night and .opencode/skills/squid-implement-night in your project.
Going by SKILL.md and its folder, Squid Implement Night needs the command-line tools its instructions call (git).
SKILL.md contains no URLs. Its commands use git, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Squid Implement Night is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.2k tokens (SKILL.md is roughly 4.9k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
