A handoff that answers back. Locations are dumb — no per-agent shaping, no receipts, no way to fix them once sent. waggle's 30-byte token resolves into each agent's own view, counts every read, and propagates a correction to every holder. A path can't do that; a URL needs a server; this needs neither. <a href="https://trendshift.io/repositories/82635?utm_source=trendshift-badge&utm_medium=badge&utm_campaign=badge-trendshift-82635" target="_blank" rel="noopener noreferrer"><img src="https://trendshift.io/api/badge/trendshift/repositories/82635/weekly?language=Rust" alt="modiqo%2Fwaggle | Trendshift" width="250" height="55"/></a> <a href="https://trendshift.io/repositories/82635?utm_source=trendshift-badge&utm_medium=badge&utm_campaign=badge-trendshift-82635" target="_blank" rel="noopener noreferrer"><img src="https://trendshift.io/api/badge/trendshift/repositories/82635/daily?language=Rust" alt="modiqo%2Fwaggle | Trendshift" width="250" height="55"/></a> <a href="#the-problem">The problem</a> · <a href="#how-it-works">How it works</a> · <a href="#install">Install</a> · <a href="#wire-it-into-your-harness">Harness setup</a> · <a href="#by-file-type">By file type</a> · <a href="#reach-local--machines--the-edge">Reach</a> · <a href="#the-tmux-switchboard">Switchboard</a> · <a href="docs/design/essay.md">The essay</a> · <a href="paper/">The paper</a> <img src="docs/assets/hero.svg" alt="The handoff, before and after: pasting the whole artifact to every subagent, versus handing off a 30-byte token that each consumer resolves into its own projection" width="940"> ## The problem We are entering the world of agent harnesses: Claude Code orchestrators fanning out subagents, Codex sessions delegating in parallel, cross-vendor agents discovering each other over open protocols. And every one of these handoffs, today, works the same way: **forward the context and hope.** The costs are measured, not hypothetical. Multi-agent systems consume ~15× the tokens of a chat session — the overhead attributed by the vendor itself to *"duplicating context across agents… and summarizing results for handoffs,"* whose one-line summary is **"each handoff loses context."** Roughly 37% of multi-agent failures trace to exactly this seam. Waggle's competitor is not another protocol. It is `"Here's /tmp/analysis.md. Use it."` — and that instinct is *correct*: a path is a 30-byte reference, which is exactly the right size for a handoff. But a raw path has **no attribution** (who made this, from what), **no adaptation** (the small-context model gets the same 9,000 tokens as the frontier model), **no lifecycle** (a stale path silently serves wrong data forever), **no telemetry** (which subagent actually read its input? which stalled?), and **no reach** (it dies at the machine boundary). <img src="docs/assets/context.svg" alt="Three context windows compared: a full handoff fills the window with the artifact again; a raw path is cheap but blind; a waggle token stays small and pulls back only budgeted slices through resolve, search, and read" width="940"> Only the *string* enters the consumer's context — the artifact behind it never travels unless something fetches it. Waggle standardizes that third pattern and enforces its one hard rule **by type**: the token travels; the artifact never auto-expands; `resolve`, `read`, and `search` return only the projection or slice the consumer asked for, under byte budgets. Cheap like a path — but the reference answers back. ## "But my subagents share a filesystem — that's already share-by-reference" It is, and that's the smartest thing you can do without waggle. A path isn't a copy; both agents point at the same bytes. Our benchmark's `reference` arm is *exactly* this — a local path plus `ls`, `grep`, `open`, `pdftotext` — and with a fair toolset it scores **90%**, competitive with waggle's 96%. If your agents are local, the task is short, and you never need to audit anything, **use the path** — waggle is overhead. The distinction isn't copy-vs-reference. It's that a path is a *location*, and a location can't answer three questions a handoff eventually has to: - **Was it read — and which parts?** `cat` and `grep` leave no trace you can query. The entire "did your subagent actually read it?" check is *impossible* with a bare path, not just inconvenient — reading a file records nothing. Our sharpest result (regions read → 99% correct; skipped → 20%) exists only because reads go through the token. - **Which version?** A path names *mutable* bytes. Correct the file mid-task and agent A read the old copy, B the new, with nothing to tell them apart — the divergent-copy failure, happening *with* a shared filesystem. Waggle snapshots at mint (content-addressed, immutable) and gives `supersede`/`revoke` with lineage. - **Reachable from where?** `file:///…` means nothing to an agent in another container or at the edge. The same token resolves unchanged across all three radii. The case for waggle is **accountability, versioning, and reach** — never that the filesystem duplicates bytes. The moment you need to *prove* what an agent read, survive the file changing, or hand off to something not on this box, a path runs out and a name doesn't. ## How it works A **token** is a ~30-byte attributed name for an artifact, minted in one call. Behind it stands an **attribution manifest**: who minted it (Ed25519-signed when the host holds an identity), for which channel, from which parent (delegation forms a lineage tree), with **variants** — different projections for different consumers. When an agent resolves the token it presents its context, and a **sealed, deterministic matcher** returns *its* projection. Everything afterward is an event in an append-only log — payload-free by construction, so funnels count without ever seeing your data. <img src="docs/assets/loop.svg" alt="The author's loop: mint, hand off one 30-byte line, consumers resolve their own projections, work is recorded as payload-free counts, the funnel reports, and a revocation travels to every replica" width="940"> **Consumption is protocol-shaped**: waggle is an MCP server. One config line in Claude Code, Codex, Cursor, or anything MCP-speaking — no SDK, no language bindings, no accounts. Locally it is one binary and a SQLite file. ## Walk the handoff, in first person The value isn't abstract. Stand in each role and it's obvious. **You are the orchestrator.** You just wrote a plan and spawned three subagents. Today you paste the plan into each prompt — three copies, re-billed every turn, and afterward you have no idea which one actually read it. With waggle you hand each the same 30-byte line. When they return, the funnel shows two resolved and read it, one never opened it — and you catch the bluff *before* you trust its answer. Found a bug in the plan? One revoke, and the correction reaches all three. **You are the subagent.** You wake up with one line: `resolve b2uQyZUC`. You resolve it into a digest shaped for *your* model, an outline so you know what's inside before you read, and `next` steps pointing you where to look. You grep for the one fact you need and pull 200 bytes — not the 9,000-token plan. You never ingest what you didn't need. **Now the subagent moves to another machine.** Nothing changes. The same line, the same resolve, the same grep — the bytes stay on the orchestrator's laptop, only the matches travel back. The loop you learned in one process is byte-for-byte the loop across the network. **And this can't live inside a harness.** Claude Code could build clever handoffs — but that cleverness would die at its boundary; a Codex subagent couldn't see it, and the orchestrator's memory of who made what, and who read it, would be prose in one harness's context, gone at the next compaction. The reference layer has to sit *outside* any single harness — a neutral substrate every harness speaks in one line — so what Claude Code mints, Codex resolves, and the receipt survives them both. Handoffs are a distributed-systems problem; solving them inside one vendor's harness logic is solving them in the one place they can't be solved. ## Install Pick one — all install the same `waggle` binary: ```bash cargo install waggle-cli # from crates.io # ...or a prebuilt binary, no Rust toolchain needed: curl --proto '=https' --tlsv1.2 -LsSf \ https://github.com/modiqo/waggle/releases/latest/download/waggle-cli-installer.sh | sh # ...or Homebrew: brew install modiqo/homebrew-tap/waggle-cli ``` The store lives at `~/.waggle/waggle.db` (SQLite, WAL); blobs sit beside it. `waggle daemon status` shows uptime, connections, and disk weight. ## Wire it into your harness Two things make a harness waggle-fluent: the **MCP server** (the tools) and the **convention-file stub** (the one standing instruction). Each is one command. All three land on the **same daemon and the same tokens** — what a Claude Code session mints, a Codex session resolves. **Claude Code** ```bash claude mcp add waggle -- waggle serve --stdio waggle init # in each repo where agents work ``` **Codex** — add to `~/.codex/config.toml`: ```toml [mcp_servers.waggle] command = "waggle" args = ["serve", "--stdio"] ``` **Cursor** — add to `.cursor/mcp.json`: ```json { "mcpServers": { "waggle": { "command": "waggle", "args": ["serve", "--stdio"] } } } ``` **You don't start a server.** `waggle serve --stdio` *is* the MCP server — your harness launches it on demand, and its shim **auto-starts a shared background daemon** the first time any harness connects (`connect_or_start`). There is no manual daemon step: nothing to run, nothing to keep alive. Restart your harness so it picks up the new tools, then confirm: ```bash waggle daemon status # → running · uptime · connections · db size ``` Prefer to run it in the foreground (for logs / debugging) instead of letting it auto-start? `waggle serve --daemon`. Stop or restart the background one with `waggle daemon stop` / `waggle daemon restart`. `waggle init` writes a short stub into `CLAUDE.md`, `AGENTS.md`, and `.cursorrules` (idempotent — it manages its own marked block). That stub is the **entire** standing instruction; everything else is taught in-band — every tool response carries up to three executable `next` steps, and `map` answers *"where am I, what are my paths?"* computed live from state. Instructions in convention files rot; envelopes can't. **The orchestrator pattern**, in practice: when you delegate, the subagent's prompt contains the handoff line and nothing else about the artifact — > Your working context: **resolve `b2uQyZUC` via waggle**. Use `search`/`read` > to pull only the slices you need; call `record --stage run` when you've > used it. The subagent finds the tools already mounted, pulls its own projection, and the funnel shows you it happened. ## By file type The lens engine is text-first, not markdown-first — structure is discovered from the content type, so the loop you learn on a report works on a lockfile. <img src="docs/assets/lenses.svg" alt="One token, the right lens for each artifact: prose affords outline/section/lines/search; source code affords symbol/lines/search plus symbol contracts, its outline extracted at mint; binaries are made text by extraction or ride as media variants" width="940"> **Prose** — mint with `--snapshot` to pin the bytes; consumers get the outline, sections, line windows, and grep: ```bash waggle mint --target "file://$PWD/q3-report.md" --snapshot waggle read --token b2uQyZUC --section "Competitor Pricing" waggle search --token b2uQyZUC --pattern "pricing" # matches travel, the file stays ``` **Source code** — `--snapshot` also runs tree-sitter at mint and stores a **symbol outline** beside the bytes. The consumer orients before it greps, reads a definition by name, and you can declare — and *prove* — what a reviewer had to reach: ```bash waggle mint --target "file://$PWD/src/contract.rs" --snapshot \ --require symbol:evaluate # a consumption contract, signed at mint waggle read --token 9u6KEr6F # overview: the symbol table of contents waggle read --token 9u6KEr6F --symbol evaluate # the exact definition, no window guessing waggle coverage --token 9u6KEr6F # { met: true } ← the required region was reached ``` Symbols work for Rust, Python, TypeScript/JavaScript, and Go; other text keeps the full line/search loop. Extraction happens only at mint — no parser ever runs on a serving path, including the edge. **Binaries (PDF, image, voice)** — extract the text with your own abilities and pass it via `--content`, or attach the media so vision/voice consumers receive it while everyone else falls through to the catch-all: ```bash waggle mint --target "file://$PWD/deck.pdf" --content ./deck.txt # searchable text waggle mint --target "file://$PWD/memo.m4a" --attach ./memo.m4a # audio → listeners ``` ## Reach: local → machines → the edge The reference doesn't stop at the process boundary. Every harness on a machine shares one daemon; daemons federate across machines; and the same tokens graduate to Cloudflare's edge by **replaying the log** — migration is a stream, because the log is the truth. Pinned snapshots replicate with the records, so `search` greps *at the edge* against content whose source file never left your laptop. <img src="docs/assets/reach.svg" alt="One token at three radii: every harness on one machine through waggled; across machines through federation; and on Cloudflare's edge where grep runs remotely while the source files never leave" width="940"> When the handoff must outlive your laptop, deploy once ([guide 09](docs/guide/09-the-edge.md)) and push: ```bash npx wrangler deploy # a Durable Object per tenant, same certified engine waggle edge push # records + snapshots replicate; the FILES never leave waggle edge status # { "health": "ok", "tools": 9 } waggle edge smoke # proof loop: mint → resolve → funnel, at the edge ``` The CLI is transparent through all three tiers — an agent's loop (mint, hand off, resolve, interrogate, report) is byte-for-byte the same whether the other end is in this process, on another machine, or on another continent. ## The tmux switchboard For the full multi-harness experience, `waggle-tmux` turns handoffs into the interface itself ([guide 11](docs/guide/11-tmux-switchboard.md)): ```bash cargo install --path crates/waggle-tmux # ships with the repo waggle-tmux up claude-code codex # choose once — everything wires itself ``` One window per harness (the tmux bar is your harness switcher), a live lineage board under each, and when an agent finishes it mints its outcome to `tmux/<destination>` — your screen **swaps** to that harness with the resolve instruction typing itself. Receipts on the board, `/exit` handled gracefully, `--seal` when the review must be provable. ## What makes it credible This repository is design-first and unusually explicit about its own discipline — the [design docs](docs/design/) are the contract, and the [**specification**](spec/waggle-spec.md) with its [conformance vectors](spec/vectors/) is the portable half (generated FROM the implementation and drift-checked in CI — an independent implementation that matches them is a waggle implementation): - **Sans-I/O core** — no clock, no entropy, no storage in the domain crates; every effect is a parameter. The same code runs in the native daemon and in Workers wasm, deterministic under test. - **Deterministic adaptivity** — same context, same projection, always; the variant matcher is sealed so the trust claim survives. - **Event-sourced with a reconstruct guarantee** — counters are cache; the log is truth; replay-equivalence is a CI property, not a slogan. - **One operations catalog** — the MCP tools, the clap CLI, the `map` navigation, and `COMMANDS.md` are four projections of one table, with parity tests that fail the build on drift. - **Verified against real infrastructure** — a differential oracle holds the edge byte-identical to SQLite over the same operations, on a real Cloudflare account. ## Status **v0.4.0 on [crates.io](https://crates.io/crates/waggle)** — the full feature set, every claim a passing test in CI (three-OS matrix + wasm + the live Miniflare edge matrix): - **the full loop** — mint / resolve / record / mutate / funnel / read / search / query / map over MCP and CLI, one shared daemon per machine; - **surgical content** — snapshots pinned content-addressed at mint; grep and windowed reads through the token under byte budgets; - **receipts** — consumption contracts (`--require`), coverage with misses named, `accepted`/`rejected` outcomes, and an escalation choreography; - **the symbol lens** — mint-time tree-sitter outlines; `read --symbol`, `--require symbol:`, zero parsing on any serving path; - **the resource projection** — MCP `resources/list`+`read`, and subscriptions that push lifecycle corrections to holders; - **federation & the edge** — daemon-to-daemon; a Durable Object per tenant; resolve p50 1.2 ms through the full HTTP-worker-DO path; - **trust** — Ed25519 over the immutable core; capability-URL private tokens; - **measured, not promised** ([benches/PERF.md](benches/PERF.md)) — 39 ns cache-hit resolves, 39 µs durable appends, a million-event funnel fold in 334 µs. The **[documentation map](docs/README.md)** holds the guides in reading order; the **[essay](docs/design/essay.md)** is why it's shaped this way, and the **[paper](paper/)** is the systems treatment. ## License MIT OR Apache-2.0, at your option. --- She never carries the field home.
