In niche enterprise SaaS workflows—where success means hitting the right endpoint with the right nested arguments in the right order — this objective mismatch shows up as silent failures: dropped required fields, hallucinated tools, or early stops after a single read. We ask whether Reinforcement Learning with Verifiable Rewards (RLVR), applied directly in the target environment, closes the gap. As a proof of concept we build a suite of five synthetic environments emulating the Jira REST v3 and Confluence v2 APIs at schema fidelity; rewards are computed entirely from the tool-call trace, with no live API, no learned judge, and no human label in the loop. Scoring prompted Qwen3-1.7B and Qwen3.5-4B on the same checkers that drive GRPO training, we find that on the four scenarios whose rewards are non-degenerate the RL-trained policy lifts average reward from a 4B-baseline range of 0.35–0.92 to 0.95–1.00, with the largest single gain on Confluence page creation (0 .35 → 1. 00). We position this as a preliminary step toward outcome-optimised small models for niche enterprise APIs, and foreground two limitations a workshop reader should weigh: hand-crafting verifiable rewards does not scale beyond the handful of endpoints reported here, and one of our five scenarios (ticket-transition) has a saturating reward shape that the prompted 4B already maxes out.  \nKeywords  \nreinforcement learning, tool use, verifiable rewards, GRPO, synthetic environments, agent evaluation, Jira, Confluence  \n1 Introduction  \nLLM-driven agents are moving from chat into workflows: opening tickets, transitioning issues, updating wikis. A growing literature treats tool invocation as a first-class capability to be elicited via supervised fine-tuning or RL on real APIs [9, 11, 15, 17], yet public RL benchmarks for agents target the open web [18], software engineering [4], or broad agentic suites [6, 13] . Niche enterprise SaaS workflows —narrow, schema-heavy, dominated by the “check the resource, then mutate it” pattern — get comparatively little attention.  \nThe deeper issue is an objective mismatch: LLMs are optimised against next-token likelihood on internet-scale text, not to act inside a particular API surface. Asked to create a Jira sub-task or a  \n∗ Equal contribution.  \nConfluence page in our suite, a prompted Qwen3.5-4B knows the rough shape of the call but fills slots wrong, omits required fields, or stops after the first read — behaviours that read as fluent under a token-prediction objective and score poorly under any check that grounds the output back to the environment (our promptedbaseline scores in Section 6 bear this out). Reinforcement Learning with Verifiable Rewards (RLVR) [1, 3, 5, 12] gives up reward modelling in favour of programmatic checkers wherever correctness can be inspected. Tool-use is naturally amenable: an agent’s output is a sequence of structured tool calls whose argument values and ordering can be inspected directly. We exploit that observation to train agents against outcome-level rewards in synthetic copies of the target environment, with no live API, learned judge, or human label in the loop.  \nContribution.
