pstack for Claude Code

A Claude Code port of pstack. A GitHub Action re-ports it from cursor/plugins every day, so it does not fall behind upstream.

44 skills and 2 agents: /pstack:how, /pstack:why, /pstack:unslop, /pstack:arena, /pstack:interrogate, /pstack:swarm, /pstack:poteto-mode, the principle-* family, and the rest.

/plugin marketplace add ShiosOS/pstack-claude-code
/plugin install pstack@pstack-claude-code

Then pick your models. Upstream's defaults are Cursor slugs, and none of them are valid here:

/pstack:setup-pstack

That writes ~/.claude/pstack-models.md. Every pstack skill reads that file, and it overrides the inline defaults. Valid values are the Agent tool's model enum, so opus, sonnet, haiku, fable, plus the inherit-parent and auto aliases.

Already running pstack via a local junction or a hand-patched clone? Remove it first. Two plugins both named pstack will collide.

pstack is a Cursor plugin. Its skills reference ~/.cursor/ paths, Cursor's tool names, Cursor's transcript layout, and Cursor-only built-ins. Hand-patching a clone works exactly once. The patches are edits to tracked files, so the next git pull conflicts, and from there the port drifts.

So the port is not a patch set. Three files do all of it:

• port/rules.mjs holds content-addressed rewrites. Each one matches a token or a shape, never a line number. Upstream can reword the surrounding paragraph, move text between files, or add whole skills, and the rules still apply.
• port/verify.mjs refuses to publish a tree that still contains a .cursor/ path, the wrong tool name, a malformed manifest, a skill whose frontmatter name does not match its directory, a broken link, a script that lost its executable bit, or a generated file that is not tracked.
• .github/workflows/mirror.yml runs both daily, commits when the output changes, and opens an issue when verify fails.

Verify is why this mirror is safe to install unattended. Upstream will eventually introduce a Cursor-ism no rule covers. When that happens the build fails and publishes nothing, instead of shipping an instruction that points at a path which does not exist. An agent reading that instruction would follow it anyway. A mirror one day stale is recoverable. A wrong one is not.

PORT.md is the full contract. It lists every rewrite and every deliberate deviation, plus the three things that are ported but cannot work here: Cursor-cloud orchestration, the benny automation pack, and upstream's model slugs.

.claude-plugin/marketplace.json   the marketplace entry
pstack/                           GENERATED, the ported plugin
port/rules.mjs                    Cursor -> Claude Code rewrites
port/overlays/                    optional local additions, most disabled
port/sync.mjs                     fetch upstream, re-port, record provenance
port/verify.mjs                   refuses to publish a broken port
UPSTREAM.json                     which upstream commit this was built from

Do not edit pstack/ by hand. sync.mjs deletes the directory and rebuilds it from scratch every run, so hand edits are lost. Change a rule or an overlay instead. That way the output cannot disagree with what the rules say it should be.

node port/sync.mjs                 # re-port from upstream main
git add -A pstack UPSTREAM.json    # stage first, see below
node port/verify.mjs               # check it
node port/sync.mjs --check         # exit 1 if the port is out of date
node port/sync.mjs --ref <sha>     # pin a specific upstream commit
node port/sync.mjs --from ../clone # re-port from a local clone, offline

Stage before verifying. Two of verify's checks read what git recorded rather than what sits on disk, because git is where those two failures show up: a script that lost its executable bit, and a generated file that a .gitignore pattern would hide from everyone installing the plugin. On Windows chmod does not stick, so an upstream script that newly becomes executable needs one git update-index --chmod=+x. Verify prints the exact command.

sync.mjs prints which rules fired and on how many files, and it names rules that matched nothing. That usually means upstream dropped the text. Sometimes it means the rule has gone stale.

When verify reports something unported:

1. Add an entry to rewrites in port/rules.mjs. Match the narrowest stable token that identifies it, not the surrounding sentence.
2. node port/sync.mjs && node port/verify.mjs.
3. Commit the rule and the regenerated tree together.

Sometimes the reference is right as it stands, either attribution or documentation of a Cursor-only feature. Add an allowlist entry to port/verify.mjs instead, with a reason and, where it is context-specific, a path pattern.
