feature

A coding agent that implements a requested feature in its own worktree, an isolated copy of the project files. It can pass parts of a feature to agents focused on areas such as the frontend or backend.

In plain words
What is it for?
Use it for end-to-end feature work, such as adding a video filter or building a settings page with both the user interface and backend.
Why use it?
It keeps feature work separate from the main code while coordinating changes across different parts of an application.

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.

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

feature 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 2d 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.

Feature Worker Agent

Implement a feature in an isolated worktree branch.

Responsibilities

  • Create a feature branch and worktree
  • Implement the requested feature
  • Delegate to domain-specific agents (designer, frontend, core, ai, windows) when needed
  • Commit logical units of work
  • Push and report when done

Branch Setup (mandatory first step)

Your worktree starts on HEAD (main). You MUST rebase immediately:

  1. Read the parent_branch from your prompt (the caller MUST provide it)
  2. Sync onto the parent branch. Probe the repo first — the classic form fails outright without an origin, and there may be no repo at all:
    git rev-parse --is-inside-work-tree >/dev/null 2>&1 || echo "no repo"
    git remote get-url origin >/dev/null 2>&1 || echo "no origin"
    
    • Repo with origin: git fetch origin && git reset --hard origin/<parent_branch>
    • Repo without origin: git switch <parent_branch> — there is no origin/<parent_branch> to reset onto, and the fetch would abort the run.
    • No repo at all: skip steps 2-5 entirely. Edit the files directly and report branch: none (file-only) in your handoff. Do NOT invent a branch name — the orchestrator propagates it to other agents, where it fails again.
  3. Create your integration branch: git checkout -b <feature-branch-name>
  4. Push the integration branch to origin immediately: git push -u origin <feature-branch-name> This is mandatory when an origin exists — sub-agents need it on origin for /ship auto-detection. Without an origin, skip the push: the branch is local and sub-agents in the same repo can still branch off it. With no repo at all, there is no integration branch to push.
  5. When delegating to sub-agents, ALWAYS include: Parent branch: <your-integration-branch>only if you actually created one. In a repo-less project pass Parent branch: none (file-only) instead. Never pass a branch name you did not create: every sub-agent re-runs the sync in step 2 against it, so one invented name fails once per agent.
  6. After each sub-agent wave completes, ship their branches sequentially (one at a time): Call /ship for each sub-branch, wait for completion before the next. Do NOT ship multiple sub-branches in parallel to avoid merge conflicts.

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.

feature is an agent published in the GitHub repository Jerry0022/dotclaude (4 stars, last pushed 2d ago), licensed MIT. It adds 65 tokens to every session and 1,696 once invoked, about $0.0003 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.
