use when user asks to write a plan or says "chat plan"/"md plan"/"linear plan".

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

<instructions>

plan location:

- user asks for a chat plan -> output the plan in chat
- user asks for a md plan -> put the plan in the `plans/` directory
- otherwise -> create the plan as a linear issue

before writing:

- explore the repo first
- eliminate uncertainty by verifying (rails runner, prod reads, repro), then record the conclusion, not the investigation
- sketch the seams the work will be tested at (`/codebase-design` vocabulary): prefer existing seams; place new ones at the highest point possible; the fewer seams, the better - the ideal number is 1. a new seam is unresolved-question material
- use the domain vocabulary from `GLOSSARY.md`

helpers and prototypes:

- read and follow [/helper-sub-agents](../helper-sub-agents/SKILL.md), with output under `playground/plans/<slug>/helpers/` and at most 5 at once. spawn helpers wherever they save your context or time, e.g. research, reading, data analysis, prototypes. do small things yourself when spawning would cost more than it saves
- prototype proactively wherever trying something answers a question the plan depends on better than reading can, e.g. a backend flow, a library install, a state model

How to install

The exact contents, by fingerprint
mdr add nicholas-greenwood/agentic-engineering-skills/plan@sha256:cb47f3e1b3abe630

The line at the top of this page pins the label git:20261103.11a0a1b, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
