agent-harness-sprint-plan

agent-harness-sprint-plan is a skill for Claude Code, Codex from bouob/agent-harness. It costs 44 tokens per session (695 once invoked), scanned A, original, MIT.

A planning guide for preparing a coding sprint before any application code is changed. It creates a complete plan for the people or automated roles that plan, build, and check the work.

In plain words
What is it for?
Use it to turn an unclear or multi-step request into a Codex-ready sprint plan. It also records whether each task follows the current model or uses a specified one.
Why use it?
It removes uncertainty before implementation by defining the goal, tasks, needed files, and model choices. This gives the plan a review point before edits begin.

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

agent-harness-sprint-plan 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 10d 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.

Agent Harness Sprint Plan

Plan a Codex sprint without implementing it. Use this skill for ambiguous or multi-step work where a plan should be reviewed before edits.

References

  • ../../references/codex-sprint-contract.md - Codex sprint artifact contract and task rules
  • ../../references/codex-config-schema.md - Codex model routing config

Step 1 - Resolve Codex Model Routing

Read Codex config in this order:

  1. ./.codex/agent-harness.local.json
  2. ~/.codex/agent-harness.json
  3. Built-in defaults from ../../references/codex-config-schema.md

Only read .codex config files. Do not read .claude/agent-harness*.json.

If no config exists, use the built-in default where every role has mode: "inherit".

Resolve each role independently. In generated plans, state for each task whether its assigned role:

  • inherits the current Codex session model and reasoning, or
  • uses an explicit model and optional reasoning_effort

If a route is malformed, warn and treat only that role as inherit.

Step 2 - Ground the Plan

Read only the files needed to understand the request. Prefer rg and targeted file reads.

Identify:

  • Goal and user-facing outcome
  • Affected subsystem or files
  • Existing conventions to preserve
  • Risks, dependencies, and likely verification commands
  • Which tasks are best mapped to planner, evaluator, code, write, research, or collect routing roles

Do not edit files during this skill.

Step 3 - Write the Sprint Plan

Produce a plan in the format from ../../references/codex-sprint-contract.md.

The plan must include:

  • Interpretation
  • Acceptance Criteria
  • parallel_batch
  • sequential_tasks
  • Verification Plan
  • Assumptions

Use 3 to 7 tasks. A task belongs in parallel_batch only when its write ownership is disjoint from every other parallel task. Read-heavy exploration, test analysis, and documentation review may run in parallel.

Each task should state the intended routing role or an equivalent note in its summary or deliverables when that affects execution quality or cost.

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.
