Spec sheet

Purpose
SignalLoop is an AI-native candidate evaluator for software engineering hiring that assesses realistic backend tasks with a constrained AI collaborator.Read 9 Oct 2026 · github.com
Product
SignalLoop is an AI-native candidate evaluator for software engineering hiring.Read 9 Oct 2026 · github.com
Intended users
The product is for software engineering hiring teams evaluating candidates’ problem framing, verification, judgment, AI collaboration, and ownership.Read 9 Oct 2026 · github.com
Integrations
The documented pilot uses Render for web/API hosting, Supabase for Postgres, Clerk for employer authentication, and AWS ECS/Fargate as an optional per-run execution provider.Read 9 Oct 2026 · github.com
AI provider
The constrained AI collaborator supports an OpenAI provider and a local fallback.Read 9 Oct 2026 · github.com
AI providers
The constrained AI collaborator supports an OpenAI provider and a local fallback.Read 9 Oct 2026 · github.com
Assessment
It evaluates candidates solving backend engineering tasks with a constrained AI collaborator and generates an Engineering Evidence Report for employer review.Read 9 Oct 2026 · github.com
Candidate workspace
Candidates use invite links to access a browser workspace with Monaco editor-backed file editing and public test runs.Read 9 Oct 2026 · github.com
Deployment options
The project documents a hosted Render/Supabase/Clerk pilot and local setup using PostgreSQL, a Docker worker, an API, and a web app.Read 9 Oct 2026 · github.com
Employer advisory
An optional bounded GPT-5.6 advisory summarizes allowlisted process evidence without changing deterministic scores, integrity labels, or recommendations.Read 9 Oct 2026 · github.com
Employer reporting
The platform generates deterministic Engineering Evidence Reports, with an optional bounded GPT-5.6 advisory that does not change scores, integrity labels, or recommendations.Read 9 Oct 2026 · github.com
Evidence captured
It captures evidence of problem framing, AI use, verification, design judgment, and candidate ownership.Read 9 Oct 2026 · github.com
Evidence report
The platform captures evidence of candidate framing, AI usage, verification behavior, design judgment, and ownership, then generates an Engineering Evidence Report for employer review.Read 9 Oct 2026 · github.com
Execution isolation
The security policy says local execution uses Docker and hosted production execution should use isolated per-run tasks.Read 9 Oct 2026 · github.com
Maintainers
SignalLoop was created as joint work by Sreenivas Makam and Ritesh Dhoot.Read 9 Oct 2026 · github.com
Notable limit
Guided role matching does not compose new questions, and the question bank is not connected to employer blueprint composition, candidate delivery, or report scoring.Read 9 Oct 2026 · github.com
Notable limitation
Guided role matching does not assemble new questions, and question-bank items are not connected to employer blueprint composition, mixed-question delivery, or report scoring.Read 9 Oct 2026 · github.com
Open-source license
The repository states that original application code and documentation are Apache-2.0 unless a file specifies otherwise, while imported question-bank content retains upstream licensing and attribution requirements.Read 9 Oct 2026 · github.com
Open-source licensing
The original application code, documentation, and internally authored assessment material are Apache-2.0 unless a file states otherwise; imported question-bank material retains its upstream licensing and attribution requirements.Read 9 Oct 2026 · github.com
Production use
The repository says its public demo assessment packs expose hidden tests, scoring rubrics, and evaluator notes, and recommends private calibrated packs for real hiring decisions.Read 9 Oct 2026 · github.com
Role matching
Guided role matching maps role or job-description requirements to the closest registered Standard or Advanced FastAPI assessment and can return unsupported-coverage results.Read 9 Oct 2026 · github.com
Security boundaries
The policy says candidate invite tokens are bearer links, public demo hidden tests and rubrics are unsuitable for real hiring, and manual evaluator review is required before hiring decisions.Read 9 Oct 2026 · github.com
Security controls
Pilot hardening includes audit events, validation and fallback error responses, retry-bounded hidden-worker calls, and basic rate limiting.Read 9 Oct 2026 · github.com
Security status
The security policy describes SignalLoop as a pilot-stage hiring evaluation system and a reference implementation rather than a hardened production SaaS.Read 9 Oct 2026 · github.com
Testing
Candidates can run public tests through a local Docker worker, and final submissions run hidden tests through the worker.Read 9 Oct 2026 · github.com
