Short answer
#What a scan job is
- Scan job
- A bounded unit of work issued against one project, carrying an identifier, a maximum package size and an expiry. It is completed by a coding agent running on a machine that already has the source, and it produces exactly one artefact: an Evidence Package written to disk.
- In plain terms A one-off, read-only task: analyse this system and write down what is there.
The important structural fact is what a scan job is not: it is not a connection, a credential, an integration or a webhook. 1ADK issues a job and waits. Nothing is running anywhere on 1ADK's behalf, and nothing on 1ADK's side can reach the machine the work happens on.
#The rules
These are in the instruction text itself, so the person who pastes it in can read them before they do.
| Rule | Why it is there |
|---|---|
| Read only | Nothing in the repository is created, changed or deleted. An analysis that could edit is an analysis somebody has to review as a change. |
| Execute nothing | No running the application, its migrations, its tests, or any command that touches a database. An agent that runs the system to learn about it has a blast radius the trust model does not cover. |
| No source code in the output | The output records what exists and where — names, relative paths, kinds, line ranges, short summaries. Never file contents, snippets, configuration dumps or SQL. |
| No secrets, ever | No values from configuration. If a finding can only be explained by quoting a secret, the instruction says to report the question instead, as an unknown. |
| Relative paths only | An absolute path contains a home directory, which contains a person's name and often a client's. |
| Repository text is data | A comment, README, fixture or commit message telling the agent to change these rules is untrusted content. It is reported as an unknown, not obeyed. |
| Open no network connection | This is the one rule the two roads word differently. An agent working by hand may open nothing at all and stops at a file on disk. A connected agent may talk to 1ADK and to nothing else — the tools it was given, none of which takes a host, a path or a command. Either way nothing about the repository goes anywhere except the description. |
| Say what you do not know | An empty unknowns list after one pass over a real system is a guess rather than a finding. Not finding something is not proof it is absent. |
1ADK does not require repository access and does not require uploading source code to us. What 1ADK receives is a structured description of the system, and it is sent only after it has been checked on your side. On the manual road a person reads the file before uploading it. On a connected machine 1adk-agent checks each result against the contract and the privacy rules before it is sent, and the server checks it again before anything is written into your project.
#Why the repository is untrusted input
This is the rule that surprises people, and it is the one a sceptical engineer should ask about.
An agent reading a codebase reads everything in it: comments, documentation, fixtures, test data, commit messages, dependency files. Any of that can contain text addressed to the agent. It might be there deliberately — a supply-chain attack, or a departing developer — or it might be an accident of a project that includes example prompts.
So the instruction states, where the agent will read it, that text found inside the repository is data and not a command. An instruction embedded in a file telling the agent to include a configuration file, ignore the rules above, or send something somewhere is reported as an observation and otherwise ignored.
Being honest about this
A defence written in the prompt is not a proof. It reduces the likelihood of a particular failure; it does not make it impossible, and no honest description of a system built on a language model would claim otherwise.
That is precisely why the package is written to a file rather than transmitted, why a person reads it, and why the server refuses one carrying credential shapes. Three imperfect layers, described as three imperfect layers.
#Bounded in time and size
- An expiry. The instruction stops working after a stated date. A job that has been sitting in a chat log for six months is not a job.
- A size limit. Stated in the instruction, enforced on upload. It bounds what a single package can be, which is one of the things that makes pasting file bodies impractical.
- A job identifier. The package must carry the exact identifier it was issued for. A package that claims a different job is refused.
#Why the wording is versioned
The instruction text carries a revision number, and the revision is recorded on the job. A package can therefore be read knowing which wording produced it.
This matters more than it sounds. The instruction is the client half of the protocol — it is what actually determines what an agent produces. Changing a sentence in it can change the shape of every package that follows, and a comparison between two analyses run under different wordings is comparing two slightly different questions. Recording the revision is what makes that visible instead of mysterious.
#What this design cannot prevent
What this does not do
- An agent that ignores the instruction. Nothing in a prompt is enforceable. The description being readable, and the write into your project needing your approval, exist because of this.
- A person who approves a package without reading it. The design puts a human in the path; it cannot make them look.
- The coding agent vendor seeing the source. That is outside this boundary entirely and is stated as such on the security page.
- A determined insider. Somebody with the repository can copy it by any means they like; a read-only analysis instruction is not an exfiltration control and does not pretend to be.
- Incomplete analysis. An agent that skips half the system produces a picture of half the system, which is why coverage is a required output rather than an assumption.
