Give engineering teams an agent that finishes the work

Hast Agent starts from an issue, reads the repository and its engineering rules, reproduces the problem in an isolated cloud environment, changes the implementation, runs the checks, and returns review-ready code. From routine fixes and missing tests to cross-service debugging, refactors, and migrations, engineers retain the architecture, merge, and release decisions.

Duplicate job after retry

Investigate why checkout retries create duplicate jobs, reproduce the failure, and prepare the smallest tested fix for review.

  1. Traced the call path and idempotency boundary
  2. Reproduced the failure with a regression test
  3. Implemented the smallest scoped fix
  4. Tests, types, and build passed

Move engineering work forward with more speed, stronger verification, and clear control

Move faster from issue to review-ready change

An agent maps the code impact, plans the change, implements it, and runs the repository's own checks before handing the result to an engineer.

Spend engineering capacity on scarce judgment

Delegate repetitive fixes, missing tests, dependency upgrades, and mechanical migrations so the team can focus on product tradeoffs and system design.

Ship with evidence, not confidence

Every change includes reproduction steps, check results, known limitations, and risk notes. Code owners still decide what merges and ships.

Bring together the context required to finish engineering work

Real engineering work never lives in one code snippet. Hast brings collaboration, documents, data, and runtime systems into one governed workspace so every task can run against the team's existing source of truth and verify the result.

Engineering collaboration

Start from requirements, code review, and team discussions, then return results to the workflows the team already uses.

  • GitHub
  • Linear
  • Slack
  • Notion

Documents and data

Read design docs, project material, spreadsheets, and email context without repeatedly moving information between systems.

  • Google Drive
  • Google Docs
  • Google Sheets
  • Gmail

Planning and runtime

Connect meetings, credentials, and authorized runtime context to incident and delivery work.

  • Google Calendar
  • Google Meet
  • Cloudflare
  • 1Password

Start with work the team knows matters but keeps postponing

The best pilot is not a demo prompt. It is a bounded, verifiable category of real work that repeatedly consumes engineering time.

Recurring defects and test debt

Start with repeated failures, fragile modules, or long-missing regression coverage and measure review and rework time.

Upgrades, migrations, and broad refactors

Split necessary but time-consuming changes into safe batches and advance work that sits outside the feature roadmap.

PR review and incident investigation

Have the agent collect evidence, reproduce issues, and perform mechanical checks before scarce expert attention is needed.

Put one real engineering task in front of Hast

Choose one repository and one recurring task. Together we will connect the context, set permissions and quality gates, and decide whether the workflow deserves to scale based on review-ready code and verification evidence.
