arn-code-batch-planning

A workflow for planning several features from sources such as a backlog, GitHub issues, Jira issues, or plain descriptions.

In plain words
What is it for?
Use it to select unplanned work, draft feature analyses, review specifications, create implementation plans, and continue through the planning pipeline.
Why use it?
It prepares multiple features in parallel while allowing their specifications and plans to be reviewed in sequence.

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

arn-code-batch-planning 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.

Arness Batch Planning

Plan multiple features in a single session with parallel pre-analysis and pipelined plan generation. Supports features from greenfield Feature Tracker (F-NNN), GitHub issues, Jira issues, or plain descriptions. Pre-analyzes all selected features in parallel using arn-code-batch-analyzer agents to generate draft specs, then guides the user through sequential review. Plans are generated in the background while the user reviews the next spec.

This skill is a sequencer. It MUST NOT duplicate sub-skill logic. All pipeline work is done by the invoked skills and agents (arn-code-batch-analyzer, arn-code-feature-spec, arn-code-feature-planner, arn-code-save-plan). Arness-code-batch-planning handles: source detection, feature selection, parallel pre-analysis orchestration, sequential spec review, pipelined plan generation, plan review, and chaining.

Step 0: Ensure Configuration

Read ${CLAUDE_PLUGIN_ROOT}/skills/arn-code-ensure-config/references/step-0-fast-path.md and follow its instructions. This guarantees a user profile exists and ## Arness is configured with Arness Code fields before proceeding.

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
