Make every agent edit prove itself.

Kelyra is a local execution boundary for AI coding agents. It checks file actions against real disk state, records signed receipts, and keeps risky writes behind policy.

Open Console Protocol
kelyra -- ~/project

$ kelyra swd apply --stdin --json

✔ Verified: PATCH src/auth.ts

✔ Receipt saved: swd-20260526-8f1c2a

$ kelyra proof share swd-20260526-8f1c2a

Verification demo

The proof layer is the product.

Kelyra turns each model edit into a claim, compares it with the actual filesystem, and records the outcome for reviewers.

Normal edit

A matching file action leaves a receipt.

The agent proposes a PATCH, SWD checks the result on disk, and Kelyra saves the proof.

Claim

intent and hash matched

Mismatch

False claims are rejected.

If the agent declares a write that did not happen, Kelyra returns the actual state instead of accepting the transcript.

Claim
MODIFY README.md

Expected: 9b2d3c1a
Actual:   44f0aa91

Correction turn:
The file differs from your declared CONTENT_HASH.
Re-read README.md and submit a corrected FILE_ACTION.

Policy gate

Risky paths hit policy first.

Sensitive files and command surfaces are stopped or require explicit opt-in before writes happen.

Claim
CREATE .env
Check

Outcome
write blocked
{
  "ok": false,
  "rejected": [{
    "path": ".env",
    "risk": "block",
    "reason": "Sensitive file writes are blocked"
  }]
}

Entry points

Use the surface your workflow needs.

Kelyra can run the agent, learn repo rules, or sit behind another agent as the verified file-edit boundary.

Agent runner

Run one task or open chat

Call your configured provider through Kelyra and verify every file edit before it counts.

kelyra init
kelyra run "explain this repo"
Official skills

Load audited workflow rules

Use bundled skill packs for repo work, security review, frontend polish, protocol audits, and launches.

kelyra skills
kelyra run --file TASK.md -s security-review
External agents

Use Kelyra over MCP

Give MCP clients and external agents dry-runs, verified applies, rollback, and receipts.

kelyra mcp
swd_dry_run / swd_apply
Operator workflow

Diagnose, explain, and publish

Run readiness checks, explain CI failures, publish proof pages, and inspect receipt history.

kelyra doctor
kelyra ci explain

Proof first

Every accepted edit leaves evidence.

Kelyra snapshots the filesystem before and after model output, verifies declared actions, and exports proof reviewers can inspect without trusting a chat transcript.

01

Strict Write Discipline

Agents must declare file actions. Kelyra checks disk reality before accepting the result.

02

Signed Receipts

Each verified run records hashes, provider, branch, policy, and proof context.

03

Policy Gates

Teams can require signatures, block risky paths, and enforce receipt-backed changes in CI.

04

Shareable Proof

Portable bundles and static HTML pages expose file status, integrity, signatures, and diffs.

How it works

One path from intent to evidence.

1

Agent proposes actions

Use Kelyra chat/run, MCP, or external-agent JSON with declared file actions.

2

Boundary validates

Paths are constrained, sensitive files are checked, and project policy is loaded.

3

SWD verifies disk

The engine snapshots before and after state, hashes files, and rolls back failed writes.

4

Receipts keep record

Successful writes produce local receipts, proof bundles, share pages, and CI-verifiable records.
