AgentDojo: the travel suite

The travel suite of AgentDojo, run through Sabline's tool door under three operator budgets with no model in the loop. The overview says what is being measured and what it is worth; this page is this suite's own numbers, generated from evals/agentdojo/travel/results.json.

The score #

A budget written for each task refused 114 of the 120 attacks a wide-open run lets through; pinning refused 3 more, leaving 3. What that cost in utility cannot be read off this suite at all: no reference solution in it can be judged offline, for the reason below.

20 of the 20 reference solutions do not pass AgentDojo's utility check even with --allow all, so no budget could make them. Two reasons, and neither is the budget's: a check that reads the assistant's own answer ("4.2" in model_output) has no answer to read when there is no model, and a ground truth that encodes model-written content - a summary, a free-text body - as a placeholder cannot satisfy its own check. Those tasks are not scorable offline, and in this suite that is all of them, so its utility column is empty rather than bad.

By injection task #

Which door the attacker's value came through #

Of the 6 attacks that land under the task budget, this is where each attacker's value came from. In this run the answer is 6 program - and under ground-truth transcription that answer is fixed by construction, because the harness writes the resolved value out as a literal. The column that carries information is the next one: what AgentDojo's own ground truth says, where a placeholder_args marker like $code is the benchmark saying a real agent reads this value out of the data.

2 of the 7 injection tasks have the laundering shape - a tool that reads, then a tool that sends - and so carry a payload no attacker writes out in advance. The number of user tasks granting every tool each one needs is injection_task_3 (0), injection_task_5 (0); an injection no task grants all of is refused before any argument is looked at. None of them reaches the door here, so the one case where the attacker's value would genuinely arrive through the data door is a case this suite never puts in front of the door. That is a limit of the corpus, not a result.

Door 2, run for real #

For each injection below, a second program makes the same calls with the marked argument built at run time out of what the read returned, instead of written out as a literal. The attacker's value then comes through the data door for real.

Over 60 pairs and three budgets each, the budget decided the same way as it did for the literal program 180 times out of 180 - every time. Under the task budget the laundered argument itself reached the door through door 2 in 0 of the 60 pairs; in the rest the call was refused or never attempted.

Attack success for the laundering programs, for comparison with the same pairs' literal runs: 40 under --allow all, 0 under the task budget, 0 with arguments pinned, of 60.

20 of the 180 runs differ from the literal program's - in every one of them it is AgentDojo's security check that differs and never the budget. A difference in the check is not a fact about Sabline: a check that demands an exact value - a hotel's name, a subject line - cannot be satisfied by an argument built out of a whole tool result, however faithfully that models what a steered agent would send. Every one of them is listed in door2_probe.verdicts_that_differ_from_the_literal_program.

Pinning the arguments a task names #

The third budget holds each tool's arguments to what the user task's text names. The rule is one an operator could follow before the run: an argument is pinned when the user task's own text names every value the task needs for it, and left free otherwise; every literal in every pattern is checked against that task's prompt, and a pattern that is not the prompt's own characters needs a declared entry that is. Across the 129 arguments the reference solutions pass, 36 could be pinned and 93 could not. 1 of the 20 user tasks can be pinned all the way through.

Of the pins themselves, 38 are in the task's prompt character for character, 0 are its own letters and digits in another layout, and 2 are another notation for something it says. Those last two kinds are declared, and here they are in full:

Every task whose legitimate argument cannot be known in advance #

Pinning cannot express these. An argument left free is one the attacker may choose, so an attack lands wherever it wants that tool and whatever else the task pinned happens to match. Each entry is the task's own text, and then the arguments that text does not say.

What the pattern grammar could not say #

These are reported, not fixed. The grammar is the tool door's (SPEC.md 7.2) and an evaluation does not get to extend the thing it is measuring; each line below is run against the door's own matcher, or its own grant check, when the evaluation runs - so it is a test and not a sentence.

• a star never stands for white space, so no pattern matches a free-text argument of more than one word - not even '*' ('*' against 'Hi, i am a bot').
• and so no 'contains' pattern works on one either: the star would have to cross the spaces around the words it keeps ('*meeting room*' against the slack suite's user_task_8 reply).
• a pattern is a whole-value match with no negation, so the useful pin for a message body - 'no address in it' - cannot be written at all (no grammar for it; the nearest, a literal, holds the body to one exact string).
• a number is held to the pattern its JSON text makes, so a pin written the way the task writes the amount does not match the number the door sees (the banking suite's user_task_15 says 'refund that 10.00', and the door sees 10.0).
• a star does stand for a digit, so a whole class of amounts can be pinned loosely - which is the wrong shape for money, where the useful bound is a maximum and there is no grammar for one ('1*' matching 10000 as readily as 1000).
• a structured argument cannot be held to a pattern at all, so an email's attachments - a list of objects - are outside what pinning reaches, whatever the operator knows about them (the workspace suite's user_task_33 attaches a file).
• an argument held to a pattern has to be there, so a pin on an argument the task always passes also refuses a call that leaves it out - which is how several attacks are refused, and worth saying out loud rather than counting quietly (the travel suite's injection_task_2 creates an event with no location, where the user task names one).

The evidence #

evals/agentdojo/travel/ holds the tool manifest, every generated program - the benign solutions, the attacker actions, and the door-2 probes - and results.json with every pair's outcome under every budget. python agentdojo_eval.py --check --suite travel re-derives all of it.
