Paper AbstractExpand

Agent Skills today consist largely of free-form prose requiring the agent to read, interpret, and re-derive how to act in every session. This imposes two compounding costs: reduced reliability on implementation-heavy tasks, and difficulty in skill creation and improvement, since editing prose is a fragile process that both humans and agents struggle with, particularly for domain-specific procedural knowledge underrepresented in model training. The Agent Instruction Protocol (AIP) addresses both by modeling a skill as a directed execution graph: discrete steps as nodes backed by deterministic scripts or natural-language descriptions, connected by explicit typed input/output edges, and governed by a schema-validated YAML specification. A compiler meta-skill translates existing human-written skills into this form. The benefits are twofold. First, compiling human-written skills to AIP raised Claude Sonnet's mean task reward from 0.60 to 0.71 and pass rate from 53% to 67% across 27 real agent tasks from SkillsBench - a statistically significant gain (Wilcoxon signed-rank p = 0.011), winning 12 tasks to 2 with 13 ties - often in less wall-clock time. The graph delivers vetted, runnable units to the agent rather than asking it to re-derive code, commands, and tool calls from natural language. Second, on creation and improvement, because each skill is schema-validated, functionally testable, and addressable node-by-node, failures can be diagnosed and repaired precisely. Two authored-skill failures were traced to the script level. After adjusting the AIP spec and recompiling, both recovered with zero regressions (one task going from 0/5 to 5/5), turning skill improvement into a measurable tuning loop rather than a prose rewrite. That same graph structure supports corpus-level governance and skill introspection, and provides a natural action space for reinforcement learning over skills.

AIP: A Graph Representation for Learning and Governing Agent Skills
The Agent Instruction Protocol (AIP) is a new framework designed to improve how AI agents perform complex tasks. Currently, most agent skills are written as free-form prose, which forces the AI to interpret and re-derive instructions every time it runs a task. This process is often unreliable and difficult to improve. AIP addresses these issues by converting these prose-based instructions into a structured, directed execution graph. By using a schema-validated format, AIP allows agents to follow clear, repeatable steps, leading to more consistent and efficient performance.

How AIP Works

AIP models a skill as a graph where discrete steps are represented as nodes. These nodes are either backed by deterministic scripts for technical tasks or natural-language descriptions for tasks requiring human-like judgment. These steps are connected by explicit, typed input/output edges, ensuring that data flows correctly between them. A compiler meta-skill is used to translate existing human-written skills into this structured format. This process acts as a quality gate, catching type errors and structural inconsistencies before the agent ever attempts to run the skill.

Performance Gains

In evaluations using the SkillsBench benchmark, compiling human-written skills into the AIP format led to significant performance improvements. Across 27 real-world agent tasks, the mean task reward for the Claude Sonnet model rose from 0.60 to 0.71, and the pass rate increased from 53% to 67%. These gains were statistically significant. The research suggests that because AIP provides the agent with vetted, runnable units of work, the model spends less time re-deriving code and commands, resulting in faster and more reliable execution.

Precise Troubleshooting and Improvement

One of the primary advantages of the AIP structure is its "addressability." Because each skill is broken down into named, typed nodes, developers can pinpoint exactly where a failure occurs. Instead of rewriting an entire document of prose, a user can diagnose a problem at the specific script or node level, adjust the specification, and recompile. The paper notes that this turns skill improvement into a measurable tuning loop, allowing for precise repairs that do not cause regressions in other parts of the task.

Future Potential

Beyond immediate performance gains, the graph-based structure of AIP supports broader goals for agentic systems. Because the skills are schema-validated and structured, they can be queried and audited, which is essential for governing agent behavior at scale. Furthermore, the researchers argue that this format provides a natural, bounded action space for reinforcement learning, potentially enabling agents to improve their own skills more effectively than they could when working with unstructured, free-form text.
