write-plan

write-plan is a command for Claude Code, OpenCode from juliusz-cwiakalski/agentic-delivery-os. It costs 5 tokens per session (655 once invoked), scanned A, original, MIT.

A command that creates or updates the implementation plan for a software change, using its existing specification.

In plain words
What is it for?
Use it to write the change plan file and associate the work with its expected branch and change folder.
Why use it?
It turns an agreed specification into concrete work while keeping the plan beside the change documentation. It also prevents planning when the required specification is missing.

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

write-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 yesterday.

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.

What it actually says

User invocation: /write-plan <workItemRef>

Writes (or updates): chg-<workItemRef>-plan.md in the same change folder as the spec.

<discovery_rules> Given workItemRef:

  1. Search for folder: doc/changes/**/*--<workItemRef>--*/
  2. Locate spec: chg-<workItemRef>-spec.md
  3. If spec not found → FAIL

Files:

  • Spec: chg-<workItemRef>-spec.md
  • Plan: chg-<workItemRef>-plan.md
  • Branch: <change.type>/<workItemRef>/<slug> </discovery_rules>

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.
