Gaps in your doc become judgment calls your developer’s agent makes.
No requirements or design doc is 100% complete. Wherever gaps exist, your developer’s agent decides for you... and you find out at delivery.
Planning, review, and QA skills only work when developers actually use them. Today, you can’t verify which steps your developer took before code ships.
Even with AI drafting with you, chasing down every edge case, state, and unstated assumption is slow and difficult. Nobody wants to move slowly, so the gaps ship.
Typical specs say what to build, never how to prove it works. The test checklist lives in your developer’s head. You’re trusting them to think through and test every case.
Every misread requirement is a round trip: re-explain, re-build, re-review, re-pay. The rework rate on outsourced work is where projects quietly die.
Runs where your team already works.
Install one skill. Your agents run Semel's exact review cascade from the harness your team already uses, locally or on remote autonomous fleets. Your models, your keys, your code.
First-class agent auth
Delegated OAuth or named tokens. Scoped, revocable, attributed.
Full-suite MCP
Anything a human can do in Semel, an agent can do.
BYO agents, harness, keys
Your code and credentials stay on your side.
You're not alone
We hear this pain every day. Robust skills and workflows exist for individual contributors, but no contributor wants to move more slowly than AI can. So they skip steps and push slop.
Build requirements with the gaps found for you.
Upload what you have: threads, PRDs, transcripts, Figma links. AI reads every artifact, finds what’s missing or contradictory, and fills the gaps in a Q&A with you. You answer in batches; nothing is assumed on your behalf.
Account recovery is mentioned nowhere. The PRD covers login, and the thread covers invites. Is password reset in scope for v1?
A design doc that survives a reviewer cascade.
Your requirements flow into a solution design doc, then through a cascade of AI reviewers: product, UX/state, architecture, QA, and security. Each one interrogates the doc from its own angle and passes findings down. Every change lands as a versioned, statement-level diff.
The test checklist is written before the work starts.
AI derives test and validation criteria from the design doc itself. Every requirement gets a checkable criterion and a way to verify it. “Done” is defined up front, not improvised by whoever builds it.
Every approval, on the record.
Reviewer sign-offs and human approvals land in one ledger: who approved what, when, against exactly which version. When someone asks “who signed off on this?”, the answer is one click, not an archaeology dig through Slack.
The review runs in your terminal. The proof lives in Semel.
Assign a review session to your own harness. It claims the frozen work package, runs the exact reviewer skills against your local worktree with your model keys, and streams verified checkpoints back. Completion mints a signed execution certificate that travels with the PR.
Approve with confidence.
Specs with no gaps. Verified agent reviews. No rework.
