Tool Registry
Every capability declared, typed, and scoped to the roles allowed to invoke it.

Service / Agent Systems
Agents With Their Hands On Real Tools
Tool-use, planning, and multi-step execution wired into your systems, with approval gates on anything that changes state.
- Every tool
- Scoped
- Every write
- Gated
- Every action
- Logged
- Where possible
- Reversible
What is included
Inside Agent Systems
The concrete pieces of work an engagement covers.
Planning
Multi-step execution with explicit state, so a failure resumes instead of restarting.
Control002
Approval Gates
Reads run freely. Writes pause and present a diff for a human to approve.
Safety003
Recovery
Retries, fallbacks, and clean escalation when the agent genuinely cannot proceed.
Resilience004
Audit Trail
Every tool call, input, and result logged in a form your compliance team accepts.
Accountability005
Cost Ceilings
Per-run and per-tenant budgets enforced in code, not discovered on the invoice.
Economics006
Unique approach
Autonomy Without The Anxiety
The question is never whether an agent can act. It is what happens when it acts wrongly.
With DarCode
- Writes gated behind human approval
- Every tool call logged and replayable
- Per-run cost ceilings enforced in code
- Tools scoped per role and per tenant
- Failures escalate with full context
- State persisted so runs resume
Typical alternative
- Agent free to mutate production data
- Opaque runs, debugged by guesswork
- A runaway loop discovered by billing
- One key with access to everything
- Silent failure, or a confident wrong answer
- Any error restarts the whole sequence
How it runs
From Kickoff To Handover
The same sequence every time, compressed or extended to fit the engagement.
- 01
Map
List the actions the agent may take and who is permitted to trigger each one.
- 02
Wrap
Expose each action as a typed, scoped tool with its own tests.
- 03
Gate
Decide which calls are safe to automate and which require a person.
- 04
Evaluate
Score whole trajectories, not single responses, against known-good runs.
- 05
Ship
Roll out per team behind flags, with budgets and audit logging live from day one.

FAQ
Frequently Asked Questions
Questions we get asked about agent systems.
Only through a scoped tool, and by default only to read. Writes pause for human approval with a diff of the intended change.
Untrusted content is never treated as instructions. Tools are scoped so that even a successful injection cannot reach anything the user could not already access.
Trajectory-level evaluation. We score the whole sequence of decisions against known-good runs, not just the final message.
We model per-run cost during the build and enforce ceilings in code, so spend is predictable before launch rather than after.
