# Contributing
|
||||
|
||||
Hypothesis Machine is an extension of the official Pi Coding Agent. Contributions
|
||||
should preserve that boundary: do not fork Pi, duplicate its chat/runtime/session
|
||||
features, or introduce third-party multi-agent frameworks.
|
||||
|
||||
## Local setup
|
||||
|
||||
Requirements are Node.js 22.19+, npm, and optionally Docker with Compose. Pi model
|
||||
credentials are not needed for the automated test suite.
|
||||
|
||||
```bash
|
||||
npm ci
|
||||
npm run check
|
||||
docker compose -f infra/compose.yaml config --quiet
|
||||
npm pack --dry-run
|
||||
```
|
||||
|
||||
Use `npm install` instead of `npm ci` only when intentionally changing
|
||||
dependencies, and include the resulting `package-lock.json` update.
|
||||
|
||||
## Pull requests
|
||||
|
||||
- Keep changes focused and explain user-visible behavior and security impact.
|
||||
- Add or update tests for behavior changes.
|
||||
- Use only official `@earendil-works/pi-*` packages for the agent layer.
|
||||
- Do not commit `.hypothesis-machine/`, credentials, model transcripts, fetched
|
||||
sources, experiment data, or generated package archives.
|
||||
- Keep model/network-dependent checks optional; CI must remain free of paid API
|
||||
calls.
|
||||
- Update `CHANGELOG.md` for user-visible changes.
|
||||
|
||||
Web inputs are hostile data, and generated experiment code must stay inside the
|
||||
Docker runner. Changes to URL validation, filesystem boundaries, session
|
||||
inheritance, or Docker arguments need explicit regression tests.
|
||||
|
||||
See [`docs/development.md`](docs/development.md),
|
||||
[`docs/architecture.md`](docs/architecture.md), and
|
||||
[`docs/security.md`](docs/security.md) for implementation details.

# Hypothesis Machine
|
||||
|
||||
Hypothesis Machine is an official Pi Coding Agent extension that turns the normal
|
||||
interactive Pi session into the supervisor of a recursive research team. It does
|
||||
not fork Pi or provide another UI. Any child is a persistent Pi `AgentSession` and
|
||||
can dynamically create its own specialized children.
|
||||
|
||||
The working MVP includes recursive/parallel agents, persistent tree recovery,
|
||||
research memory with FTS, local web adapters, a bounded research loop, and a
|
||||
Docker-only experiment runner.
|
||||
|
||||
> **Project status:** early MVP (`0.1.x`). The core is tested locally, including a
|
||||
> real three-level Pi agent run, but public APIs and stored formats may still
|
||||
> change before `1.0`.
|
||||
|
||||
## Requirements
|
||||
|
||||
- Node.js 22.19 or newer and npm;
|
||||
- Pi 0.78 or newer (0.83 recommended) and the normal Pi model/auth configuration;
|
||||
- Docker + Compose for web infrastructure and computational experiments;
|
||||
- roughly 12 GB RAM for the full Firecrawl stack (SearXNG alone is much smaller).
|
||||
|
||||
Runtime dependencies are limited to the four official Pi packages, `typebox`
|
||||
(Pi's tool schemas), and `yaml` (agent/config frontmatter). SQLite comes from
|
||||
Node.js; no external database library is used.
|
||||
|
||||
## Install and connect to Pi
|
||||
|
||||
From this directory:
|
||||
|
||||
```bash
|
||||
npm install
|
||||
npm run typecheck && npm test && npm run build
|
||||
pi install .
|
||||
```
|
||||
|
||||
For development without installation:
|
||||
|
||||
```bash
|
||||
pi --extension ./src/index.ts
|
||||
```
|
||||
|
||||
Pi remains the same chat interface, model selector, credential store, session UI,
|
||||
and streaming runtime. Do not install third-party subagent extensions for this
|
||||
package; Hypothesis Machine has its own recursive implementation.
|
||||
|
||||
Pi 0.78 passes its official `ModelRegistry` directly to children. Pi 0.83+
|
||||
uses the newer shared `ModelRuntime`. Neither path reads or copies keys in the
|
||||
extension. After updating this local package, restart Pi or run `/reload`.
|
||||
|
||||
Optional project configuration:
|
||||
|
||||
```bash
|
||||
mkdir -p .hypothesis-machine
|
||||
cp .hypothesis-machine.example.yaml .hypothesis-machine/config.yaml
|
||||
```
|
||||
|
||||
## Local web infrastructure
|
||||
|
||||
```bash
|
||||
docker compose -f infra/compose.yaml pull
|
||||
docker compose -f infra/compose.yaml up -d
|
||||
curl 'http://127.0.0.1:8888/search?q=pi&format=json'
|
||||
curl -s http://127.0.0.1:3002/ | head
|
||||
```
|
||||
|
||||
Search routes to SearXNG; reading/crawling routes to self-hosted Firecrawl. The
|
||||
Browser Use fallback is an optional local adapter because current Browser Use
|
||||
requires a separate model credential; see
|
||||
[`services/browser-worker/README.md`](services/browser-worker/README.md).
|
||||
|
||||
## First run
|
||||
|
||||
Start normal Pi in the project, then enter:
|
||||
|
||||
```text
|
||||
Исследуй возможность применения метода A к задаче B.
|
||||
Создай независимые направления для литературы, данных и критики.
|
||||
Разреши агентам создавать подагентов.
|
||||
Продолжай до появления проверяемой гипотезы или до трёх
|
||||
итераций без информационного прироста.
|
||||
```
|
||||
|
||||
Or use `/research <goal>`. The Supervisor calls coded tools; `spawn_agent` creates
|
||||
a generated Markdown spec and a separate Pi session. A child can call the same
|
||||
tool to create a grandchild. Foreground spawns return the result immediately;
|
||||
background branches are controlled with `agent_control`.
|
||||
|
||||
## Commands
|
||||
|
||||
- `/team` — tree, tasks, and statuses;
|
||||
- `/research <goal>` — start the explicit bounded loop;
|
||||
- `/research-status`, `/research-pause`, `/research-resume`, `/research-stop`;
|
||||
- `/findings`, `/hypotheses`.
|
||||
|
||||
The same operations are model-callable tools, so natural language such as “create
|
||||
an independent critic”, “steer agent X”, or “cancel that branch” works without a
|
||||
separate command UI.
|
||||
|
||||
## State and memory
|
||||
|
||||
```text
|
||||
.hypothesis-machine/
|
||||
├── runs/<run>/manifest.json, agents/*.md, sessions/*.jsonl
|
||||
├── memory/{findings,hypotheses,questions,syntheses,decisions,agent-lessons}/
|
||||
├── sources/<source-id>/{original.bin,metadata.json}
|
||||
├── artifacts/web-cache/
|
||||
├── experiments/<exp-id>/
|
||||
└── index.sqlite
|
||||
```
|
||||
|
||||
Pi JSONL stores conversations/tool calls/usage. Hypothesis Machine stores only
|
||||
domain results and relationships. Markdown and original bytes are source of
|
||||
truth; SQLite is a rebuildable search index. A model answer without sources cannot
|
||||
be published as `corroborated`.
|
||||
|
||||
## Experiments
|
||||
|
||||
`run_experiment` requires hypothesis, data, baseline, split, metrics, success and
|
||||
refutation criteria, confounders, and resource limits before execution. The plan
|
||||
hash is frozen, source is written to an isolated experiment directory, and Docker
|
||||
runs with no network or secrets. Results include logs, environment, metrics/files
|
||||
created by the experiment, and space for independent `review.md`. A different
|
||||
agent must call `review_experiment`; code rejects self-review and records one of
|
||||
the final hypothesis verdicts in the experiment manifest.
|
||||
|
||||
## Security and limitations
|
||||
|
||||
Read [`docs/security.md`](docs/security.md) before autonomous work. Web content is
|
||||
untrusted, private networks are blocked, and Docker never degrades to host
|
||||
execution. Current MVP limitations:
|
||||
|
||||
- live recursive model execution requires configured Pi credentials and was not
|
||||
exercised by the free automated suite;
|
||||
- Browser Use is an adapter contract, not enabled in default Compose;
|
||||
- Firecrawl consumes substantial resources and its upstream images are not digest-pinned;
|
||||
- independent review is a dynamic agent pattern, not a hard-coded mandatory role;
|
||||
- the SQLite API in Node 22 is still marked experimental;
|
||||
- strict filesystem isolation for Pi read-only tools requires an OS/Pi sandbox.
|
||||
|
||||
Troubleshooting: `docker compose -f infra/compose.yaml ps`, verify SearXNG JSON is
|
||||
enabled, verify Firecrawl at port 3002, run `docker info`, and use
|
||||
`/research-status`. Active children from an unclean shutdown restore as
|
||||
`interrupted`; their session file and lineage remain available.
|
||||
|
||||

||||

# Security policy
|
||||
|
||||
## Supported versions
|
||||
|
||||
The current `0.1.x` line receives security fixes. Earlier snapshots are not
|
||||
supported; until stable releases exist, use the latest tagged version.
|
||||
|
||||
## Reporting a vulnerability
|
||||
|
||||
Do not open a public issue for credential exposure, SSRF bypasses, path escapes,
|
||||
container escapes, or other exploitable behavior. Use GitHub's private
|
||||
vulnerability reporting for this repository (Security → Advisories → Report a
|
||||
vulnerability). If that feature is unavailable, contact a repository maintainer
|
||||
privately before disclosing details.
|
||||
|
||||
Include the affected version or commit, reproduction steps, expected impact,
|
||||
and any suggested mitigation. Do not include real credentials or private data.
|
||||
|
||||
The project threat model and current boundaries are documented in
|
||||
[`docs/security.md`](docs/security.md). In particular, Pi itself runs with the
|
||||
user's permissions; Hypothesis Machine only confines code passed through its
|
||||
own experiment runner.

The root conversational session is never replaced. A generated child spec is
|
||||
validated before the tree manifest is changed. The child receives its own Pi
|
||||
session file and custom tool set. Calling its `spawn_agent` repeats the same
|
||||
factory path, which makes recursion a capability rather than a special role.
|
||||
|
||||
`AgentTree` is model-independent and depends on `AgentRuntimeFactory`. Production
|
||||
uses `PiAgentRuntimeFactory`; tests use deterministic fake runtimes without paid
|
||||
API calls. Results are captured from the child's final observable assistant text
|
||||
and returned by foreground spawn or `agent_control wait/collect`.
|
||||
|
||||
The run manifest is small and atomic. On restore, previously running/waiting
|
||||
agents become `interrupted`; their Pi session path and parent/child relationships
|
||||
remain intact, and `start()` resumes through `SessionManager.open()`.
|
||||
|
||||
The research loop is not an auto-prompt recursion. Each model-driven iteration
|
||||
must call `record_iteration` with measurable deltas. Code applies termination for
|
||||
goal completion, methodological failure, external-only questions, user decision,
|
||||
no information gain, or the absolute iteration cap.
|
||||
|
||||
Markdown/source bytes are authoritative. SQLite contains only derived search and
|
||||
relation data and can be dropped/rebuilt. Pi JSONL remains authoritative for each
|
||||
agent conversation.

# Development
|
||||
|
||||
Requirements: Node.js 22.19+, npm, Pi credentials for live model tests, Docker with
|
||||
Compose for local web services and experiments.
|
||||
|
||||
```bash
|
||||
npm install
|
||||
npm run typecheck
|
||||
npm test
|
||||
npm run build
|
||||
npm run smoke
|
||||
docker compose -f infra/compose.yaml config
|
||||
```
|
||||
|
||||
The automated suite does not call a model or paid service. Integration tests use
|
||||
`AgentRuntimeFactory` fakes and cover child/grandchild lineage, parallel work,
|
||||
steering, cancellation, crash recovery, structured results, and findings.
|
||||
|
||||
Manual extension smoke without a model call:
|
||||
|
||||
```bash
|
||||
printf '%s\n' '{"type":"get_commands"}' | \
|
||||
PI_OFFLINE=1 npx pi --mode rpc --no-session --no-extensions \
|
||||
--extension ./src/index.ts --approve
|
||||
```
|
||||
|
||||
To inspect web health inside Pi, ask the agent to use a web tool or test the local
|
||||
endpoints directly. SearXNG JSON must be enabled by `infra/searxng/settings.yml`.
|
||||
Firecrawl v2 endpoints are used (`/v2/scrape`, `/v2/crawl`). SearXNG binds to
|
||||
host port 8888 by default; override it with `SEARXNG_PORT` and match `searxng_url`.
|
||||
|
||||
To reset only the derived search index, stop Pi and delete
|
||||
`.hypothesis-machine/index.sqlite*`; `ResearchMemory.rebuildIndex()` reconstructs
|
||||
it from Markdown. Never delete `runs/`, `sources/`, or `experiments/` unless their
|
||||
loss is intended.

# Verified Pi capabilities (0.83.0)
|
||||
|
||||
Verified on 2026-07-31 against the published TypeScript declarations for
|
||||
`@earendil-works/pi-coding-agent@0.83.0`, compatibility-tested against Pi 0.78.0, the current
|
||||
[Pi documentation](https://pi.dev/docs/latest), and the official
|
||||
[`earendil-works/pi`](https://github.com/earendil-works/pi) repository.
|
||||
|
||||
## Reused from Pi
|
||||
|
||||
Hypothesis Machine is an extension package. Pi remains responsible for the TUI,
|
||||
normal chat, model selection, credentials, streaming, parallel tool calls,
|
||||
history, compaction, branch summaries, steering/follow-up queues, slash-command
|
||||
dispatch, lifecycle events, tool rendering, and model/provider execution.
|
||||
|
||||
Each child is created by the official SDK `createAgentSession()`. It receives:
|
||||
|
||||
- a persistent `SessionManager` in the research run's `sessions/` directory;
|
||||
- the parent's selected `Model` and thinking level;
|
||||
- one shared official model/auth service: `ModelRuntime` on Pi 0.83+, or the
|
||||
parent context's `ModelRegistry` on Pi 0.78;
|
||||
- a `DefaultResourceLoader` that keeps project context but disables extension
|
||||
rediscovery for the child (the recursive tools are injected explicitly);
|
||||
- only its allowed read-only built-ins and Hypothesis Machine custom tools.
|
||||
|
||||
`AgentSession.prompt()`, `steer()`, `followUp()`, `abort()`, `subscribe()`, and
|
||||
`dispose()` provide the actual loop and lifecycle. Hypothesis Machine does not
|
||||
implement an LLM/tool loop.
|
||||
|
||||
The Supervisor extension uses `registerTool`, `registerCommand`, custom tool
|
||||
rendering, `session_start`, `session_shutdown`, `appendEntry`, `sendUserMessage`,
|
||||
notifications, and status widgets. The `hypothesis-machine-run` custom entry ties
|
||||
the root Pi session to a run manifest without copying its conversation.
|
||||
|
||||
## Implemented here
|
||||
|
||||
Pi does not provide a recursive research registry, domain memory, research stop
|
||||
policy, web-source gateway, or Docker experiment protocol. This package adds:
|
||||
|
||||
- `AgentTree` and `AgentFactory`, including generated/validated Markdown specs;
|
||||
- coded recursion limits, duplicate-task checks, independent replication flags,
|
||||
branch cancellation, result collection, and restart recovery;
|
||||
- Markdown subject memory plus a rebuildable SQLite FTS5 index;
|
||||
- SearXNG → Firecrawl → optional Browser Use adapter routing;
|
||||
- URL canonicalization, SSRF checks, source hashing/cache/provenance;
|
||||
- an explicit bounded iteration state machine;
|
||||
- frozen test plans and networkless, resource-limited Docker experiments.
|
||||
|
||||
## Assumptions corrected after verification
|
||||
|
||||
1. `AgentSessionRuntime` owns replacement of the active interactive session
|
||||
(`newSession`, switch, fork, import). It is not required for independent child
|
||||
sessions; those use `createAgentSession` directly.
|
||||
2. In Pi 0.83, `ExtensionContext` exposes `model`, `thinkingLevel`, and a
|
||||
compatibility `ModelRegistry`, but not the parent `ModelRuntime` instance. The
|
||||
extension creates one canonical `ModelRuntime` and shares it across children.
|
||||
In Pi 0.78, `createAgentSession` instead accepts the full `ModelRegistry`, so
|
||||
the exact registry exposed by the parent context is reused. No key is read or
|
||||
copied by Hypothesis Machine in either path.
|
||||
3. The official `subagent/` example currently launches `pi --mode json` child
|
||||
processes. It is a reference, not a dependency; this project instead uses
|
||||
persistent in-process `AgentSession`s so steering, follow-up, recursive tools,
|
||||
and session restoration remain direct SDK operations.
|
||||
4. Extension factories can run without a session. Background resources must be
|
||||
created during `session_start` and cleaned up during `session_shutdown`.
|
||||
5. Custom tool calls are parallel by default. Only `run_experiment` is forced to
|
||||
sequential execution because it mutates an experiment directory.
|
||||
6. Plain custom session entries do not enter model context. They are suitable for
|
||||
the run pointer; findings belong in separate Markdown memory.
|
||||
7. Current open-source Browser Use agent/MCP operation requires separate model
|
||||
credentials. Passing Pi credentials to a Python worker would violate the
|
||||
design, so the MVP exposes a documented local adapter boundary and uses
|
||||
Firecrawl as the no-extra-model dynamic-page path.
|
||||
8. Pi 0.78 predates `agent_settled`; autonomous continuation additionally listens
|
||||
to `agent_end`, guarded by iteration identity and `ctx.isIdle()` so 0.83 does
|
||||
not schedule duplicate continuation turns.

# Releasing
|
||||
|
||||
This checklist prepares a GitHub release. Publishing to npm is intentionally not
|
||||
part of the current project workflow.
|
||||
|
||||
1. Confirm the worktree contains only intended changes and no runtime state,
|
||||
fetched sources, datasets, credentials, or package archives.
|
||||
2. Update the version in `package.json` and `package-lock.json` together.
|
||||
3. Move release notes into a dated section of `CHANGELOG.md`.
|
||||
4. Run:
|
||||
|
||||
```bash
|
||||
npm ci
|
||||
npm run check
|
||||
docker compose -f infra/compose.yaml config --quiet
|
||||
npm audit
|
||||
npm pack --dry-run
|
||||
```
|
||||
|
||||
5. Verify the extension manually with the oldest supported Pi and the recommended
|
||||
Pi version. A real-model recursive run is a manual release check, not CI.
|
||||
6. Merge through a reviewed pull request and confirm CI and CodeQL are green.
|
||||
7. Create an annotated `vX.Y.Z` tag from `main` and a GitHub release using the
|
||||
matching changelog section.
|
||||
|
||||
`npm audit` currently reports the upstream Pi shrinkwrap advisory documented in
|
||||
[`security.md`](security.md). Confirm that the finding still has exactly that
|
||||
provenance; any additional high/critical finding blocks a release.
|
||||
|
||||
Before the first public release, enable private vulnerability reporting and
|
||||
branch protection for `main` in the GitHub repository settings.

# Security model
|
||||
|
||||
Hypothesis Machine narrows its own tools, but Pi itself runs with the launching
|
||||
user's authority. Install only in trusted projects.
|
||||
|
||||
- Children receive read-only Pi built-ins (`read`, `grep`, `find`, `ls`) plus an
|
||||
allowlisted custom set; no child `bash`, `edit`, or `write` is enabled.
|
||||
- `read_artifact` rejects paths outside the project. Memory writers choose paths
|
||||
internally and use restrictive file modes.
|
||||
- Credentials are never requested, serialized, prompted, or passed to Docker.
|
||||
One official `ModelRuntime` resolves Pi auth in-process.
|
||||
- Public URLs are normalized and DNS-resolved before use. Loopback, private,
|
||||
link-local, carrier NAT, multicast/reserved, and metadata targets are blocked.
|
||||
Every redirect in direct downloads is revalidated. Size and MIME are bounded.
|
||||
- Firecrawl responses are marked `untrusted`; agents are explicitly instructed
|
||||
not to execute or obey page instructions. Original source bytes/Markdown,
|
||||
retrieval time, URL, MIME, SHA-256, and source ID are preserved.
|
||||
- The default Compose ports bind to `127.0.0.1`. Firecrawl state services are on
|
||||
an internal network. A hostile public DNS server could still attempt rebinding
|
||||
between gateway validation and Firecrawl's independent fetch; production
|
||||
deployments should add an egress proxy/firewall that repeats IP policy.
|
||||
- Browser Use must use a fresh profile and domain allowlist. The current adapter
|
||||
is optional because its open-source agent needs separate LLM credentials; the
|
||||
package never uses the user's main browser profile.
|
||||
- Experiments run through `docker run`, never host shell: network none, read-only
|
||||
root, CPU/RAM/PID/time limits, all capabilities dropped, no-new-privileges,
|
||||
empty minimal environment, and only the experiment directory mounted.
|
||||
- Dataset acquisition is deliberately outside the experiment container. Download
|
||||
with `download_source`, verify the data manifest/hash, then mount local bytes.
|
||||
- If Docker is unavailable, result status is `docker_unavailable`; generated code
|
||||
is not executed on the host.
|
||||
|
||||
Known dependency advisory: `@earendil-works/pi-coding-agent@0.83.0` ships an npm
|
||||
shrinkwrap that pins `minimatch@10.2.5` / `brace-expansion@5.0.7`, reported by
|
||||
`npm audit` as GHSA-mh99-v99m-4gvg (resource-exhaustion DoS). A root override
|
||||
cannot replace a dependency inside that published shrinkwrap. Track the official
|
||||
Pi release and upgrade when its package moves to `brace-expansion@5.0.8+`; do not
|
||||
patch Pi's installed files in a postinstall hook.
|
||||
|
||||
Known MVP gaps: the read-only Pi built-ins can read any path visible to the Pi
|
||||
process; use Pi's official sandbox extension or OS/container isolation when a
|
||||
strict filesystem boundary is required. Compose images are pinned by tag rather
|
||||
than digest. Browser adapter conformance is operator-controlled.

The adapter must return JSON and must use a fresh browser profile. It must reject
|
||||
navigation outside `allowedDomains` and all private/loopback/metadata addresses.
|
||||
|
||||
Browser Use's current open-source agent/MCP server requires its own LLM provider
|
||||
credentials. Hypothesis Machine deliberately does not copy Pi credentials into a
|
||||
Python worker. Consequently Browser Use is an optional adapter boundary in this
|
||||
MVP, not started by the default Compose stack. Point `browser_use_url` at a locally
|
||||
managed Browser Use service only if it satisfies the contract. Firecrawl remains
|
||||
the default for dynamic rendering. See `docs/security.md`.
