Feature Sprint

What it does

When your agent uses it

• Tasks that involve PRD writing
• Tasks that involve Planning
• Tasks that involve Subagents

Example prompts

• “/feature-sprint”

Requirements

• Python 3

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

1. 1Read implementation-plan.md → extract tasks with checkbox state ([ ] pending, [x] done)
2. 2Read context.md → extract parallel_groups, target_repo, quality_gates
3. 3Use TaskCreate for each pending task (visual tracking)
4. 4Wire addBlockedBy from parallel_groups[*].blocked_by

What it can do on your machine

Read from SKILL.md and the folder at commit 8a10541. It shows what the files ask for, not the result of running them.

• Tool permissions

  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.

• Runs code

  Ships 3 files in scripts/ (Python), which the agent can run.

  Shell commands in SKILL.md call:

  • git

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  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.

• Credentials

  Names no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Feature Sprint loads about 1.9k tokens when it runs, and up to ~2.9k if it reads all its reference files. Until then it costs about 103 tokens; SKILL.md has 572 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~103

When it runs · the whole SKILL.md, loaded when a task matches

~1.9k

With references · SKILL.md plus every file in references/, read only if the agent opens them

~2.9k

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.

Safety

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); the scripts in this folder are not scanned.

feature-sprint

description

Execute the implementation plan produced by /feature-spec. Loads tasks from tmp/feature-specs/{slug}/implementation-plan.md, hydrates them as Claude Tasks, runs parallel groups via subagents in the correct repo (OSS sibling at ../packmind or the proprietary repo in cwd), syncs progress back to checkboxes, commits per group, and runs Nx quality gates. Resumable across sessions via checkbox state.
