Guardrail hooks that block secret leaks and broken pushes. An independent model reviewing every diff before it ships. Cost-tiered routing so cheap tasks run on cheap models. A second brain so nothing gets solved twice. This is what actually sits behind the fixed price.

real secret values an agent can read into its own context
Five hooks that actively block unsafe agent behavior.
Every one of these exists because it closed a real failure mode — not speculative hardening.
- A code change
- The agent writes it
- Every pushFive blocking gates
- Ships to production
- 01
push-guard
Denies any push to a protected branch if the remote moved on, or if it's a force-push. No exceptions, no --force-with-lease past main.
- 02
senior-review
Before code reaches a protected branch, an independent, stronger AI model reviews the full diff and can reject it with numbered findings — a second opinion, not a rubber stamp.
- 03
secret-shield
Scans every push — and every fresh clone — for exposed credentials, including env-var names that leak by themselves regardless of their value.
- 04
quality-gate
Refuses to let an agent end its turn with code that doesn't typecheck. A green build isn't a suggestion here — it's a requirement.
- 05
env-guard
Agents can never read a real secret value into their own context — not through the editor, not through a shell trick. Nothing they do legitimately requires it.
Any gate can say no. The change goes back to the agent — nothing reaches the main branch until all five pass.
Cheap tasks run on cheap models. Hard calls escalate. That's the actual token-burn optimization.
Four tiers, matched to the work — not one expensive model doing everything.
- Fast, low-cost model
Search
Read-only breadth search — where is X used, which files import Y — so raw file dumps never land in the expensive context window.
- Mid-tier model
Mechanical work
Fully-specified, multi-file work: renames, boilerplate, applying a spec that's already been written.
- Top-tier model
Visual work
Every non-trivial UI decision — cheaper models design poorly, so visual work never runs on anything less.
- On-demand senior model
Architecture calls
Escalation for hard judgment calls and bugs that failed twice — read-only, returns advice, not edits.
Context survives across projects — it isn't re-derived, or lost, every session.
A structured, persistent knowledge base means a session never starts from zero, and a lesson paid for on one engagement doesn't get relearned on the next. Four things get written down every time:
- 01Decisions
- 02Clients & people
- 03Project state
- 04Gotchas
Best practice that fires automatically — not best practice someone has to remember.
Each skill is a scoped capability that activates itself when the work matches it. A payment endpoint pulls in the security checklist whether or not anyone thought to ask for it.

The machinery is ours. The output is yours.
None of the above matters unless it changes what lands in your repository. Four things it changes.
- 01
An audit trail, not a chat log
Every change arrives as a commit carrying the gate results and the review that let it through. Six months later you can still see what was decided and why.
- 02
Acceptance criteria before the build
Nothing starts without a written definition of done. If we can't agree on what finished looks like, we don't start — that's cheaper for both of us.
- 03
Written handover as standard
ADRs for the decisions, runbooks for the operations, documentation for the parts that outlive the engagement. Updates in writing, not in a status meeting.
- 04
No lock-in
Your repository, your infrastructure, your code. Nothing here runs on a proprietary runtime you'd have to keep paying us to operate.
Gem, our own macOS utility, is built and released on this exact setup — same fleet, same five gates, same senior sign-off. The repository is public, so its commit history is the audit trail described here.
