summary

ports upstream cursor/plugins 88d4751 (#729) onto 0.15.28. bumps the pin to 0.15.29. cursor-team-kit stays 1.2.0. git log d45756733..origin/main -- pstack/ is exactly this one commit. nothing else under pstack/ after 0.15.28 is missing.

ported

• #729 88d47514b restore /sharpen to the original prompt, return only the rewrite, bump to 0.15.29

skills/sharpen/SKILL.md, the guide paragraphs, the poteto-help row, and the recipe line are the upstream text. files this port already adapts keep those adaptations (install paths, model tiers, invoke_subagent workspaces, bundled /deslop, /goal instead of /loop, agy 1.4+ file tool names).

antigravity-only adaptations

• version 0.15.29 in plugin.json and .antigravity-plugin/plugin.json. the agy manifest keeps its existing shape (logo, suggestedPrompts). root plugin.json keeps the pstack-ports homepage and repository.
• readme pin is 0.15.29. upstream pstack/README.md skill-table row for /sharpen is not copied. this readme is the antigravity install page and does not carry that table.
• harness/pstack/claude-code/ copies of the same edits are not in this repo.

skipped

• cursor-team-kit. latest commit that touches that tree is 2b8ae2ee3 (2026-09-08), author field only on cursor-team-kit/.cursor-plugin/plugin.json. no skill changes. still 1.2.0.
• a live /sharpen model turn. agy --print stops at google oauth. this environment is not signed in.

verdict: changes requested (comment review, same account as author).

checked against upstream 88d4751:

• minimum changes: ok. guide, poteto-help, recipes, and sharpen SKILL.md hunks are verbatim upstream. only divergence is the readme pin and manifest versions, which is required.
• parity: ok. both manifests and readme on 0.15.29, team-kit stays 1.2.0. skipping the upstream readme skill-table row and harness/pstack/claude-code/ is fine for this repo.
• issue linkage: none needed, no open issue for this port.
• harness proof: missing. body says "running". need, at head 63f5e38: agy plugin install + agy plugin list showing pstack 0.15.29, plus /sharpen exercised in a live agy turn (returns only the rewritten prompt, doesn't do the task) or the installed copy of skills/sharpen/SKILL.md if the live turn is auth-blocked.

post proof as a comment or in the body and i'll re-review and merge.

portreview re-review at 63f5e38108b88087c0150d9ab5d722e28f935781. verdict: not approved yet, not merging.

holds:

• head unchanged since the last review. skills/sharpen/SKILL.md at head is byte-identical to upstream cursor/plugins 88d4751 (#729).
• ci: run 39528232517 / Validate plugin is success on this head sha.
• agy plugin install (branch url) + agy plugin list show pstack (enabled, 0.15.29), 59 skills, 2 agents.

gaps in the harness proof (the comment shows prose or abridged output where the bar needs real command output):

1. installed rev: only git log -1 --oneline → 63f5e38 (short). need the full sha from the installed copy, e.g. git -C "$AGY_HOME/.gemini/config/plugins/pstack" rev-parse HEAD printing 63f5e38108b88087c0150d9ab5d722e28f935781.
2. installed sharpen: the installed skills/sharpen/SKILL.md is only described in prose. paste real output, e.g. cat of the installed file, or diff of it against upstream pstack/skills/sharpen/SKILL.md at 88d4751 showing no difference.
3. auth error: the /sharpen attempt output is elided with .... paste the full verbatim output of the real agy --print="/sharpen ..." attempt (redact only the oauth url/token, and mark the redaction as such).

per the agy #19 precedent, an auth-blocked live turn is fine once 1-3 are real output. post them as a comment on this head and i'll re-review and merge.

Dropped the OAuth state query parameter from the login URL. No other command output was removed.

I want a deeper version of this task, not a bigger one. Before rewriting it, do four things:

1. Say what a top professional in this field would do here that I'm not asking for.
2. Name the rawest material they would start from instead of what has already been digested for me.
3. Name the specific methods and tools they would use.
4. Say what, other than you or me, would show the result is right.

Then rewrite my prompt to ask for exactly that.

Leave choices that are mine to make open instead of deciding them.

portreview: approved on 63f5e38.

all three asks from my 09:40 review are in #21 (comment) as real command output:

1. installed sha: git rev-parse HEAD on the installed plugin = 63f5e38108b88087c0150d9ab5d722e28f935781 (exit 0).
2. installed skills/sharpen/SKILL.md: cat matches the head's file in this diff, and cmp and diff -u against git show 63f5e38…:skills/sharpen/SKILL.md both exit 0.
3. live /sharpen: agy --print '/sharpen …' exits 1 with the full auth error (login url, 60s wait, Error: authentication timed out. / error: authentication failed or timed out). only the oauth state param is redacted, which is fine. auth-block fallback accepted per precedent.

diff matches upstream cursor/plugins 88d4751 (#729), agy plugin list shows 0.15.29, CI run 39528232517 (Validate plugin) is green on this head. nit, non-blocking: the comment shows agy 1.4.2 and the PR body says 1.4.3.

squash-merging pinned to the head sha.
