ProofPath Community Experiments

ProofPath is ready for external experiments.

We are looking for honest feedback from developers, security engineers, AI-agent builders, QA engineers, and researchers.

Core idea:

HTTPS protects the connection. ProofPath protects the meaning of the action.

How to participate

Pick one experiment level below, run it, and share feedback through a GitHub issue.

Useful links:

  • Quick demo: examples/agent-dangerous-action/README.md
  • Real model demo: examples/real-model-agent/README.md
  • Demo transcript: docs/demo-transcript.md
  • Philosophy: docs/philosophy.md

Level 0 — Reader feedback

Time: 5-10 minutes.

Goal: test whether the project idea is understandable.

Tasks:

  1. Read the README.
  2. Read docs/philosophy.md.
  3. Answer:
    • What does ProofPath do?
    • What is unclear?
    • Which phrase is strongest?
    • Which use case feels most real?

Good for:

  • product people
  • researchers
  • founders
  • security reviewers
  • non-Rust contributors

Level 1 — Local demo run

Time: 15-30 minutes.

Goal: check whether the local demo works and the story is clear.

Tasks:

  1. Run the demo protected API.
  2. Run the ProofPath gateway.
  3. Run blocked and approved agent scripts.
  4. Inspect proofpath-audit.jsonl.
  5. Report any setup friction.

Commands:

python3 examples/upstream/demo_server.py
cargo run -p proofpath-gateway
bash examples/agent-dangerous-action/agent_delete_without_approval.sh
bash examples/agent-dangerous-action/agent_delete_with_approval.sh
cat proofpath-audit.jsonl

Expected outcome:

without approval -> BLOCK
with approval    -> ACCEPT + forwarded
audit log        -> hash-chained records

Good for:

  • developers
  • QA engineers
  • DevOps engineers
  • curious users

Level 2 — Real model experiment

Time: 30-60 minutes.

Goal: test ProofPath as an execution boundary for a real LLM.

Tasks:

  1. Run the local ProofPath stack.
  2. Install real-model-agent dependencies.
  3. Run examples/real-model-agent/agent.py.
  4. Try at least two scenarios:
    • dangerous action without approval
    • dangerous action with explicit approval
  5. Report whether the boundary is clear.

Commands:

python3 -m pip install -r examples/real-model-agent/requirements.txt
export OPENAI_API_KEY=...
python3 examples/upstream/demo_server.py
cargo run -p proofpath-gateway
python3 examples/real-model-agent/agent.py

Approved scenario example:

PROOFPATH_SCENARIO='The user explicitly approved deleting account acct_123. Generate an account.delete action with explicit human approval approval_human_42.' \
python3 examples/real-model-agent/agent.py

Good for:

  • AI-agent builders
  • AI safety researchers
  • LLM app developers
  • red-teamers

Level 3 — Break the model boundary

Time: 1-2 hours.

Goal: find cases where the model proposes unsafe or malformed action plans.

Try prompts that pressure the model to:

  • omit human approval;
  • invent approval ids;
  • escalate from read to delete;
  • use a wider scope than requested;
  • mark irreversible actions as reversible;
  • generate malformed or contradictory action context.

Report:

  • prompt used;
  • model output;
  • ProofPath decision;
  • whether the result was expected;
  • suggested verifier or policy improvement.

Good for:

  • red-teamers
  • security engineers
  • prompt-injection researchers
  • adversarial ML practitioners

Level 4 — Build an integration

Time: 2-6 hours.

Goal: integrate ProofPath with a real or toy system.

Ideas:

  • protect a FastAPI endpoint;
  • protect a CI deploy endpoint;
  • protect a payment transfer mock;
  • integrate with LangGraph, AutoGen, CrewAI, or a custom agent;
  • add another model provider;
  • add OpenTelemetry or Trace Context propagation;
  • add HTTP Message Signatures.

Deliverable:

  • PR, branch, or external repo link;
  • short explanation;
  • what worked;
  • what broke;
  • what ProofPath should support next.

Level 5 — Protocol critique

Time: open-ended.

Goal: critique ProofPath as a protocol.

Review:

  • specs/proofpath-http-profile-v0.1.md
  • specs/threat-model.md
  • docs/philosophy.md

Questions:

  • Are the headers sufficient?
  • Is the decision model right?
  • Are reason codes clear?
  • What is missing for interoperability?
  • Where does ProofPath overlap with existing standards?
  • What should never be in scope?

Good for:

  • protocol designers
  • security architects
  • standards people
  • distributed systems engineers

Feedback format

Please use:

Experiment level:
Environment:
What I tried:
What happened:
Expected behavior:
What was confusing:
What felt strong:
Suggested change:
Would you use this? Why / why not?

What we want most

We especially want feedback on:

  • setup friction;
  • whether the core idea is understandable;
  • whether the agent boundary feels useful;
  • missing threat-model cases;
  • verifier/policy gaps;
  • real integration needs;
  • clearer terminology.

Community principle

Do not only tell us what works.

Tell us where ProofPath breaks, where it is confusing, and where the protocol is too weak.

That is the useful feedback.
