Add evolver plugin: self-evolving agent memory#110
Conversation
Adds the evolver plugin (MIT) to the marketplace: session hooks that recall what worked on past tasks, detect improvement signals while editing, and record outcomes at session end, scoped per workspace. Degrades gracefully without any extra install; the optional @evomap/evolver npm package unlocks the full review-and-solidify pipeline. - evolver/: plugin dir (.cursor-plugin/plugin.json, hooks, skills, command, rule) - .cursor-plugin/marketplace.json: register evolver Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

- session-end: watchdog timeout now runs proceed() instead of emitting {}
bare, so a session outcome is no longer silently dropped when stdin stays
open past the timeout (was a real data-loss path).
- session-start: gate main() on stdin end/2s-watchdog with an emit-once guard,
consistent with the other hooks; no behavior change but no pipe race.
- session-start: belongsToWorkspace no longer blanket-includes foreign
workspace_id-tagged entries when our own id can't be resolved — falls back to
cwd matching, so a shared user-level graph can't leak another project's recall.
- _paths: findMemoryGraph(projectDir) now resolves a project-local
<projectDir>/memory/evolution/memory_graph.jsonl when it exists (matching the
docs), before the user-level fallback; both hooks pass their projectDir.
- README/SKILL: corrected the claim that hooks auto-detect/invoke the installed
engine — they don't; @evomap/evolver gives you the CLI (evolver run/review)
to run the pipeline separately, fed by the memory the hooks record. Also fixed
stale hook filenames in the README table and the bundling description.
Verified: node --check all hooks; watchdog path now records; project-local
path resolution + user-level fallback; official validate-plugins.mjs passes.

Hi @poteto — thanks for maintaining this marketplace. This PR adds the evolver plugin (self-evolving agent memory via session hooks; MIT, clean-room hooks). It is green on Cursor Bugbot and passes Could you point me to the review process / rough timeline for third-party plugin submissions, and let me know if there is anything you’d like changed? Happy to iterate on anything. |

Update: I realized the official path for third-party plugins is the marketplace submission form at cursor.com/marketplace/publish (reviewed by the Cursor team), not a PR to this repo. Closing this in favor of submitting evolver through that flow. Thanks @poteto, and apologies for the noise! For reference, the plugin lives at https://github.com/EvoMap/evolver-cursor-plugin (MIT, Bugbot-green, passes validate-plugins.mjs). |

What
Adds evolver — a self-evolving agent-memory plugin — to the marketplace.
Evolver gives the agent a persistent, auditable evolution memory via session hooks:
Plus a
capability-evolverskill, an/evolvecommand, and a recall-and-record rule. In a non-git folder it surfaces a one-line notice that memory is inactive instead of failing silently.It works with zero extra setup (local memory). Installing the optional
@evomap/evolvernpm package unlocks the full review-and-solidify pipeline; the hooks degrade gracefully when it's absent.Structure
evolver/— plugin dir:.cursor-plugin/plugin.json,hooks/(+hooks.json),skills/,commands/,rules/,README.md,LICENSE..cursor-plugin/marketplace.json— registersevolver.License
MIT. The hook scripts are an original clean-room implementation (Node built-ins only, no external deps) written from the hook behavior spec — not derived from the GPL-licensed
@evomap/evolverengine. Source repo: https://github.com/EvoMap/evolver-cursor-pluginValidation
node scripts/validate-plugins.mjs→ All plugins validated successfully. All hook scripts passnode --check; each reads stdin / writes JSON / exits 0 and never throws.Note
Medium Risk
Hooks run automatically on every session and file edit, write persistent data under the user home directory, spawn git/curl subprocesses, and may POST outcomes when Hub env vars are set.
Overview
Adds the evolver Cursor plugin to the repo and registers it in
.cursor-plugin/marketplace.json, so users can install persistent “evolution memory” for the agent.The new
evolver/package wires three Node hooks (sessionStart,afterFileEdit,stop) that recall recent successful outcomes into session context, flag improvement signals in edited content, and on task end classify the git diff into signals/status/score and append a JSONL entry under~/.evolver/...(or an existing project graph). Optional EvoMap Hub recording uses env credentials andcurl. Supporting pieces include workspace-scoped recall filtering, a hardenedworkspace-idfile under.evolver/, plus a skill,/evolvecommand, and rule documenting recall → work → record. Hooks are designed to always exit 0 with JSON and degrade when git or Hub is unavailable.Reviewed by Cursor Bugbot for commit abae3d4. Bugbot is set up for automated code reviews on this repo.
