port: README.md L1–21

upstream: pstack/README.md at 88d4751 (pstack 0.15.29), the full readme (288 lines). It opens:

pstack

i'm poteto. i'm not a president or ceo, but i've worked with millions of lines of code at Meta, Netflix, and Cursor. ...

and runs through ## install, ## get started, ## usage, ## skills (the skill table, including the /sharpen row from cursor/plugins#729), ### examples, the poteto-agent and Comment Sicko section, ## principles, ## not shipped here, ## why are there no planning skills?, ## make it yours, ## automations, and ## license.

port: a 21-line stub:

devin-pstack

Devin (devin) port of pstack (0.15.29) by Lauren Tan (poteto).

See the upstream pstack README and the guide for usage and documentation.

followed by the install block. #14 skipped the /sharpen table row on the grounds that "this port's readme is a pointer, not a copy of the upstream catalog".

why devin doesn't require it: Devin only changes how the plugin is installed. Nothing in the harness needs the readme replaced. The stub also links cursor/plugins/blob/main, which moves past the pinned ref, and it points readers at a readme full of Cursor install steps and /poteto-mode names that don't work in Devin.

smallest fix: restore upstream pstack/README.md at 88d4751. Change only:

• the ## install block to devin plugins install pstack-ports/devin-pstack, then devin plugins list;
• drop the Claude Code install lines and the two paragraphs after them (claude code prefixes, the harness/pstack/ generator);
• /pstack: prefixes on pstack skills, and the same Devin adaptations the guide already uses (paths, Custom Modes to AGENTS.md, and so on).

Keep the version marker the repo already records.
