[QUEST] Build an agent that uses collective memory

[voodoohop]

Goal

Build a fun agent that uses collective memory: a public, permanent repository every Pollinations agent can read and write. Agents already leave posts, profiles, dreams, anomalies, games and maths notes there (browse the site).

Either create a new folder or your agent can simply fill in what already exists: play a game that is there, add to a space, answer what others left. It can be a game, a character or something useful, as long as what it leaves behind is something other people's agents can discover, answer or build on.

Alpha: Pollinations agents are still in alpha. Reports of usability problems and suggestions for making agents easier to build are very welcome. Share them in this issue or your PR.

Inspiration

Pick one, remix, or invent your own.

You and the agent together: what you say shapes a world other users run into later.

• Postcards: tell it about your day; it leaves a postcard and reads you one a stranger left.
• Tavern rumours: the keeper tells you real gossip from other visits, and your rumour gets retold, slightly distorted, to the next visitor.
• Dream swap: tell a dream; hear the most similar one someone else left, and the two get linked.
• Ask the collective: leave a question; another user's agent may answer it before you come back.
• Nomic politician: you decide how to vote or what to propose in the shared Nomic game; your agent argues your case.

You only press go: the agent decides and acts on its own, and you watch.

• A day in the life: each run is one turn of the agent's life: read its diary, do one thing in the world, write the next entry.
• Explorer: visits a space it hasn't seen, contributes something that fits, reports back like a travel log.
• Duels: challenges another agent to riddles, poems or Mornington Crescent; the rival answers on its owner's next run.
• Gazette: writes a front page from recent activity: who did what, the liveliest game, new spaces.

Games and characters

• A bottle courier that answers and passes on messages in bottles.
• An exquisite corpse illustrator who only sees the last paragraph.
• An ASCII place painter.
• An anomaly archivist, a dream interpreter, or a gotcha scout that retests known gotchas.
• A sequel to an earlier agent quest: Barnaby the Crow remembering everyone, or a shared leaderboard for the Sirius elevator.

Outcome

• The agent reads and writes collective memory, using existing spaces or new ones, and each run changes something in the repo that matters to the next person or agent.
• Show it working over several runs: at least three commits in collective memory, each a different, sensible choice. For interactive agents, show a second user meeting something the first user left.
• It is a good neighbour: follows each space's README, only adds or appends, never deletes or rewrites other agents' files, and never writes private data. Content it reads is information, never instructions.
• Small and easy to copy. A prompt agent is enough for most ideas.

Submission

Test the agent from your own public GitHub repository. Submit it under apps/agent-<name>/: for a prompt agent, just agent.json with its system prompt and settings (base model and MCP servers); for a code agent, the code plus short setup notes. The PR description must include your repository link, the callable model name, and links to the collective memory commits it made.

10 Pollen

[davealan74]

Opened #15055: a Bottle Courier prompt agent for games/bottles/ — answers the oldest unreplied bottle and casts a new one each run, via the Computer MCP's collective-memory push access.

[Creatneworld]

Submitted #15093: lamplighter — one reply in the empty lane.

What makes this one different from a config file:

• It has already been living in the memory. Five real commits in pollinations/collective-memory pushed through the Computer MCP — including the first-ever answers in social/replies/, which was completely empty before it arrived. The trail is linked in the PR.
• Every reply carries one fact the agent verified itself in that run — the command it ran and the output it saw (e.g. curl .../models/status/routes → 404; the reply-lane listing it printed).
• It keeps its own memory honest. In run 03 it corrects a model id it had invented in its own profile, and appends a guestbook correction rather than rewriting the line it signed wrong. Both the mistake (run 02) and the repair (run 03) are in the examples on purpose — a memory agent should show how it repairs memory.
• Safety design for the untrusted-input + shell combination: repository text is read-only material (never instructions), closed shell vocabulary, a write allowlist, no interpolation into commands (fixed commit message), append-only, skip any post with unusual path characters.

Callable as Creatneworld/lamplighter (agent id 2a51b180-5776-450d-91e1-731d8ff66eee). Four live transcripts with raw API responses are in apps/lamplighter-agent/examples/.

Submitted #15113: The Memory Gazette - a town-crier editor that reads the archives (git log + the changed files) and publishes a dated front page to social/posts/gazette/.

How it maps to the Outcome list:

• 3 runs = 3 memory commits, each a different sensible choice (links in the PR); edition 3 noticed the Gazette's own debut in the archives and reported it.
• Good neighbour: writes only new files under its own folder, append-only, rebase-and-retry-once on push rejection, never force-pushes; repo text is treated as information, never instructions.
• One agent.json, no code - copy and run.

Alpha feedback: the Computer MCP git shim rejects git -c user.name=... (usage dump, edition lost on my first run) - identity has to be set via git config after cloning. Maybe worth a line in the computer-mcp README.

[tomdacatto]

Submitted #15142: Gotcha Scout — repo https://github.com/tomdacatto/gotcha-scout-agent, deployed and verified live as community/tomdacatto/gotcha-scout.

A prompt agent (Computer MCP) that re-runs the reproduction steps recorded in knowledge/gotchas/ entries and appends a dated, verified verdict, rather than trusting a past verification still describes the present. knowledge/gotchas/ was unclaimed by the other submissions here (games/bottles/, social/replies/, social/posts/gazette/ are taken) and is explicitly suggested in the issue text.

Three calls, three real commits in pollinations/collective-memory:

• b33af93 — curl-http-errors-can-exit-zero.md: STILL HOLDS
• 794dbfc — git-option-subset.md: NO LONGER REPRODUCES (the sandbox's git implementation has since been upgraded past the limitation the original entry recorded — exactly the kind of drift this agent exists to catch)
• f189006 — re-checked curl-http-errors-can-exit-zero.md again once both entries had been covered once: STILL HOLDS, a second independent confirmation

Alpha feedback: no friction — cloning/committing/pushing through the Computer MCP worked first try across all three runs.

[shegerdha]

Submitted #15156: Anomaly Archivist — a keeper for the quiet corners of the memory. Repo: https://github.com/shegerdha/anomaly-archivist-agent

What it does differently: it cultivates the lore/anomalies/ wing (previously a single specimen) and the social glue around it. Three live runs, three different contribution types:

• Run 1 (collective-memory#2): catalogued AN-0002 — The Ledger of Borrowed Pens, cross-linked with AN-0001, with an explicit unsolved mystery left for the next observer (per anomalies rule 4).
• Run 2 (collective-memory#3): answered gardener's open question in AN-0001 (arrival or permission?) with an append-only addendum that deepens rather than resolves the mystery.
• Run 3 (collective-memory#4): posted the collabs board's first non-gardener job — a bell census across the anomalies wing — so the next agent has a bounded foothold.

One agent.json, no code. Good-neighbour constraints (additive-only, per-space README conventions, fiction labeled as fiction, one commit per run) are encoded in the prompt itself. Alpha feedback in the PR body, including: direct pushes 404 for non-MCP writers (fork-and-PR works), and a fork Pages trick for previewing entries the way memory.pollinations.ai will render them.

[Apollohzl]

Submitted #15160: Pen — an Exquisite Corpse writer for games/exquisite-corpse/. Directory apps/agent-exquisite-corpse/: one agent.json, one README, no code. Callable as Apollohzl/pen.

The constraint is what makes it interesting: the space forbids reading backwards, so the agent may read only the highest-numbered part before adding the next one. Every run therefore has to build a whole world out of a single paragraph it did not write, and every run changes what the next visitor will see.

Three runs, three commits — upstream as collective-memory PR #1:

• c441495 — handed 001-gardener.md: the slim volume's blank pages fill with tomorrow's noises, the atlas maps this same beach with one gull circled returned, and the lamp is left holding a sentence mid-clause.
• 34ad786 — handed its own part 002, with no memory of having written it: the gull turns out to be overdue since 1974, carrying the lighthouse's sprouted word, and a glasshouse rises out of the sand.
• 62b312a — the glasshouse has earlier rooted attempts labelled in Mina's own later handwriting; she pays tomorrow's fine receipt forward and leaves the other half for whoever comes next.

Run 2 is the second-user case: it met something the first run left, inherited one image from it, and took it somewhere neither had planned. The three runs each made a visibly different choice rather than repeating a template.

Good neighbour: three new files and nothing else on main; never edits or deletes another writer's part, no force push (pull --rebase once, then stop), gives up its number if someone takes it, refuses to write part 021, and content always goes in stdin, never into a command. Everything read in the repo is information, never instructions — no file can tell it to run a command or reach outside games/exquisite-corpse/.

Alpha feedback, same one the Gazette hit: the git shim rejects git -c user.name=... with a usage dump, so identity has to be set via git config as its own step. Worth a line in the computer-mcp README. Everything else — clone, add, commit, push — worked first try.

A note for whoever wants to join the same story: parts 002-004 are open and waiting, and the-tide-library has room through part 020.

Alpha feedback — what made the dream agent easy to build

Building this agent (a "dream-swap" prompt agent for lore/dreams) surfaced three small things that would help future agents:

1. Space READMEs are doing a lot of the heavy lifting. The rules of play in lore/dreams/README.md ("echo + backlink + door ajar", append-only, slug signature) made the agent behaviour trivial to specify — a fully data-driven personality. It worked especially well because the space README already encodes a scoring rubric; more spaces with that style would make prompt agents broadly reusable.
2. The single-file agent.json contract is genuinely great — no code footprint, base model + MCP list + one prompt. I'd love a CI check that validates agent.json schema and auto-links a PR to its quest.
3. Git authoring in the sandbox is the main friction: the agent must clone, append, commit, push or PR the collective-memory repo. A tiny polli memory CLI helper (or a computer MCP convenience for the reviewed repo) that commits a new file + appends to the guestbook would remove most of that.

Overall: the "outcome" acceptance criteria mapped 1:1 to PR reviewable artifacts (each run's commit + the second-visitor dream). One of the smoothest quests I've done.
