The build detects every visible GPU's compute capability and compiles only those architectures; cross-compilation is rejected. + +All native compilation happens during the Cargo build: the `promptforge-gateway-local` crate's build script (backed by the `promptforge-gateway-build` crate) compiles the submodule into a Release `llama-server`, records a versioned manifest (source commit, tool identities, architectures, per-file SHA-256), and embeds the manifest and runtime files into the gateway binary. At runtime the gateway never invokes a compiler or build tool: it validates the embedded payload against the manifest, checks that the host provides the declared CUDA Toolkit runtime DLLs, and atomically stages the files into the operator cache. A valid matching installation is reused without restaging, and a CUDA build never silently falls back to the Vulkan archive. + +Build failures surface as Cargo build errors from the build script. Staging failures surface at gateway startup as a provisioning error naming the validation that failed (tampered payload, target mismatch, missing toolkit DLL).

Companion sources follow the main source's rules: an `https` URL requires a `sha256` pin, a local path may go unpinned, and plaintext `http` is rejected. Both companions are chat-only and validated at load. The resolved paths live in the child's launch state, so a respawn re-emits the exact verified artifacts, and a model without companions gets the same command line as before companions existed. + ### Derived client credentials There is no `[workshop.gateway]` sub-table. The hosted workshop reaches the gateway through its own HTTP client, and that client's `base_url` and `api_key` derive from the boot `[server]` section: the URL is the `[server]` bind with an unspecified address swapped for loopback (`0.0.0.0` becomes `127.0.0.1`, `[::]` becomes `[::1]`), and the bearer key is the `[server]` `api_key` itself.

Full evidence with source URLs is in the companion research file dated 2026-08-29. + +## The convergent architecture + +Every mature agentic UI converged on the same two-level information architecture: + +1. **A persistent run list** - cards with five fields: title, status (running / waiting / done / failed), current-step one-liner, elapsed time or tokens, and a click target. "Waiting for input" is a first-class state everywhere. +2. **A run detail view** - header (status, elapsed, stop/pause/resume), a grouped chronological step timeline with collapsed subagents, a diff/artifact panel, raw escape-hatch tabs, and mid-run steering input. + +The main chat stays a clean narrative of collapsible summary rows; every row deep-links to full-fidelity detail. + +## The event stream is the product + +The highest-leverage architectural choice, made independently by Cursor, AG-UI, and the OpenAI Agents SDK: **the UI is a pure function of one append-only, typed event log**. Live streaming and history replay share one renderer and one schema. + +The AG-UI protocol is the converging cross-framework standard (adopted by Google, LangChain, Microsoft, AWS Bedrock AgentCore, Mastra, PydanticAI). Its vocabulary maps directly onto what Workshop needs: + +- Lifecycle: `RUN_STARTED` / `RUN_FINISHED` / `RUN_ERROR`, `STEP_STARTED` / `STEP_FINISHED` - every run brackets strictly. +- Text: `TEXT_MESSAGE_START` / `CONTENT` (delta) / `END`; reasoning gets its own family including an encrypted/opaque variant. +- Tool calls: `TOOL_CALL_START`, `TOOL_CALL_ARGS` (streams partial JSON so forms pre-fill), `TOOL_CALL_END`, `TOOL_CALL_RESULT`, joined by `toolCallId`. +- State: `STATE_SNAPSHOT` on connect, then RFC 6902 JSON Patch deltas - exactly the reconnect story a WebSocket server needs. +- Subagents: an optional `subagentRunId` on every event, so concurrent subagent streams are attributable rather than one undifferentiated stream. + +Serde-tagged Rust enums map to this cleanly, and Workshop's existing protocol module already enforces the "every pushed frame is classified" discipline this requires. + +## Human-in-the-loop is interrupt/resume, not inline blocking + +LangGraph and the OpenAI Agents SDK converged on the same model, and it matches the deferred-completion design we discussed for `user_input()`: + +- The run pauses, persists state, and emits a typed interrupt payload. +- The client resolves it with a resume command carrying the user's value. +- Interrupted runs consume no compute and can resume much later. + +OpenAI's ChatGPT agent adds two refinements worth copying: interruption is a checkpoint, not a cancellation (redirect mid-task without losing progress, partial results on stop), and takeover mode visibly suspends observation/logging while the user types credentials. + +## Approvals are a policy ladder, not a prompt stream + +Every tool shipped tiered gating: allowlist -> sandbox -> classifier -> human, with "don't ask again" persistence on every prompt. Two documented failure modes matter more than the mechanism: + +- Claude Code's "don't ask again" rules frequently fail to match, causing re-prompt storms that users file bugs about. +- Codex orchestrators built "approver daemons" to auto-confirm prompts - proof that per-action modals do not scale. + +For Workshop's first version, the prompt itself is the policy: `user_input()` is the only gate, and the prompt author decides where it sits. Declarative allow/deny lists can come later. + +## Subagent visibility is the number one gap in shipping products + +Claude Code's most complained-about weakness is subagent invisibility: a collapsed `Done (10 tool uses ยท 45.6k tokens)` line with no live status, no reachable dispatch prompt, and users with parallel agents "standing in the parking lot going 'they're still in there I think.'" Cursor's documented bugs are the mirror image: subagent cards flicker between status texts and running subagents vanish from the chat pane. + +The proven fix (Claude Cowork, GitHub's session logs, Devin): a compact card in the main stream - name, live status, elapsed time, current tool call - that expands or opens a full trace including the dispatch prompt and final result. GitHub groups similar tool calls to cut noise and collapses subagent activity behind a heads-up line showing what it is doing right now. + +This validates the structured-activity design for Workshop: `task_started` / `task_delta` / `task_finished` events keyed by a stable task id, a durable summary card in chat, and a separate high-volume detail stream. Stable IDs and debounced status transitions are not polish; their absence is a shipped bug in two major products. + +## Streaming and thinking + +- Stream data, not components. Vercel's RSC approach (streaming React components) is now marked experimental - quadratic transfer, no parallel tool calls.

It is a discovery. Every framework started with templates and grew an agent layer. None went the other way. PromptFlow's YAML DAG is being retired April 2027, replaced by code-first Python. The evolutionary trajectory is one-directional: template, then agent loop, then harness. + +## The layering pattern + +The dominant relationship between the two modes is containment, not coexistence.

This is directly relevant to PromptForge: a harness .lua file should be able to call a document prompt via execute(), and a document prompt should work unchanged. The two types compose. + +## No system uses a scripting language for the loop + +This is the most important finding. The seven major agent harnesses surveyed occupy a spectrum: + +| System | Loop | User can change the loop? | +|---|---|---| +| Cursor | Hardcoded ReAct while-loop | No. Rules, hooks, MCP extend it. | +| Claude Code | Hardcoded ReAct async generator | No. CLAUDE.md, hooks, MCP extend it. | +| OpenAI Agents SDK | Hardcoded while-loop in Runner | No. RunConfig, handoffs, guardrails configure it. | +| Microsoft Agent Framework | Hidden agent loop + BSP workflow | Workflow graph is user-defined; inner loop is not. | +| AG2 | Middleware-driven model loop | Yes. Middleware stack is composable. Closest to scriptable. | +| LangGraph | User-defined StateGraph | Yes. The graph IS the loop. Maximum control. | +| Bedrock AgentCore | Harness (config) or Runtime (bring your own) | Split: managed or fully custom. | + +Configurability comes through composition patterns (middleware in AG2, graph topology in LangGraph, hooks in Cursor, handoffs in OpenAI), never through interpreted loop scripts. PromptForge using Lua for the agent loop is genuinely novel. + +## Three projects already use Lua for LLM agent work + +The combination of Lua-as-agent-runtime has independent prior art, but for tool execution, not loop control: + +- onetool (Rust + sandboxed Lua REPL) - LLM writes Lua for computation instead of using dozens of specialized tools. Functions tiered as safe/unsafe/forbidden. +- ORCS-CLI (Rust + capability-gated Lua) - every agent behavior (agents, skills, tools) is a Lua script with explicit capability grants. +- Lua.ex (pure Elixir Lua VM) - one VM per conversation, per tool call, per user. Designed for AI agent use. + +All three chose Lua for the same reasons: small runtime, clean embedding API, straightforward sandboxing, LLMs write correct Lua. + +## The host/script boundary patterns + +Seven domains of embedded Lua scripting provide the design vocabulary: + +**Game AI (behavior trees).** Host provides frame timing and world state. Script provides decision logic. Communication is through a shared blackboard (read/write data) and success/fail/running signals. This maps to: host provides model calls and tool dispatch, script provides the agent policy, communication is through the event log and var. + +**Redis.** Host provides atomicity (single-threaded execution) and the data store. Script provides multi-step logic that would otherwise require round-trips and optimistic locking. The script cannot escape the sandbox. This maps to: host provides async execution and the gateway client, script provides the turn logic. + +**OpenResty.** Host owns the event loop and request lifecycle. Script provides logic within defined phases. The configuration file literally contains both declarative config and imperative code. This is the closest structural parallel to PromptForge's document/harness split. + +**Neovim.** Host provides the editor core. Script provides all high-level features (LSP, treesitter, plugins). Trust is implicit - if you installed the plugin, you trust it. The boundary has been moving toward Lua over time. This maps to: human-authored harness programs get Neovim-level trust; LLM-authored code would need tighter controls. + +**WoW addons.** The most sophisticated Lua sandboxing in production. Taint propagation tracks trust through data flow. Protected functions require hardware events. This is relevant if PromptForge ever runs untrusted prompts from a marketplace. + +**Roblox/Luau.** Capability-based sandboxing with hierarchical permission intersection. Relevant for multi-tenant prompt execution (MCP server running untrusted prompts). + +## The "prompt-as-program" ecosystem + +Thirteen systems treat the prompt specification as executable code: + +- Constrained-decoding engines (LMQL, SGLang, Guidance, Outlines) control generation token-by-token +- Schema-contract systems (Instructor, BAML, DSPy) treat the output shape as the spec +- Typed agent frameworks (Pydantic AI, Genkit, Marvin) wrap agent loops in type-safe functions + +The industry signal is clear: config/YAML approaches are being retired. Code-first with type safety is the direction. BAML is the most relevant parallel - a DSL compiled to typed clients, with the thesis that "agent-authored software needs a source format precise enough for machines to edit and legible for humans to own." + +## What this means for PromptForge + +The evidence supports two prompt types sharing one runtime: + +**Document prompts (.md)** - the current model. Sections, prose, variable substitution, the semantic picker, the built-in tool loop. The structure carries meaning. For reports, analyses, and structured single-run work. Unchanged. + +**Harness programs (.lua)** - a Lua program with access to the same host calls. No sections, no prose, no picker, no implicit tool loop. For interactive agents, chat loops, and long-lived sessions. New. + +The runtime provides the same kernel to both: the gateway client (models.chat, models.infer), tool dispatch (tool_call), the Observer (runtime.events), the store, var, and cancellation. The entry point differs: the document prompt is parsed and walked by the section executor; the harness program is loaded and run as a Lua main loop. + +Composition: a harness program can call a document prompt via execute(). A document prompt is a callable unit of work that runs and returns a result. The harness orchestrates; the document does focused work. This matches the dominant layering pattern found across every surveyed framework. + +## Confidence levels + +- The two-type split is necessary: high. Every framework arrives here. The evolutionary direction is one-way. +- Lua is the right scripting language: high. Three independent projects chose it for the same reasons. The embedding API is designed around the host/script boundary. PromptForge already uses it. +- The agent loop as a Lua program is novel: high. No surveyed system does this. The closest are LangGraph (user-defined graph) and AG2 (composable middleware), both in the host language. +- Document prompts can invoke harness programs and vice versa: medium. The evidence supports layering (documents as components of programs), but bidirectional invocation is less common. Haystack and LlamaIndex do it; most others layer one way. + +## Open question + +Where does the harness .lua file live? Three options: + +1. In prompts/ alongside .md files, distinguished by extension. Simple, but mixes two very different things. +2. In a separate directory (harnesses/, agents/). Clean separation, but splits the prompt catalog. +3. As a section type within a .md file (a pure-Lua section with no prose). Keeps one file format, but stretches the document model. + +The evidence does not settle this. Promptflow uses separate file extensions (.dag.yaml vs .flex.yaml). BAML uses its own extension (.baml). Most frameworks use the host language's native file format (.py, .ts). The pragmatic choice is probably option 1: .lua files in prompts/, with the runtime detecting the format from the extension. + +*2026-08-29 11:17 - claude-opus-4-8-thinking* diff --git a/design/research/research-harness-context-assembly.md b/design/research/research-harness-context-assembly.md new file mode 100644 index 00000000..be12b9b3 --- /dev/null +++ b/design/research/research-harness-context-assembly.md @@ -0,0 +1,164 @@ +# What agent harnesses put in their contexts + +Eight coding-agent harnesses examined.

Artifact download, digest pinning, dominion binding, and child supervision (respawn of a dead child) are unchanged from a chat child. diff --git a/third_party/llama.cpp b/third_party/llama.cpp new file mode 160000 index 00000000..fb0e6b62 --- /dev/null +++ b/third_party/llama.cpp @@ -0,0 +1 @@ +Subproject commit fb0e6b621917488d623437349fb5361e0ac21c70 diff --git a/workshop.example.toml b/workshop.example.toml index f9aaead2..9d3e82ca 100644 --- a/workshop.example.toml +++ b/workshop.example.toml @@ -1,11 +1,11 @@ # PromptForge Workshop example configuration. # -# The promptforge-ws desktop shell generates ~/.promptforge/workshop.toml +# The promptforge-workshop desktop shell generates ~/.promptforge/workshop.toml # from a built-in template on first run, so no setup is needed there.
