17. Project Context & Skills
Load AGENTS.md, skill files, and inject them into the prompt.
pi loads project-specific instructions from AGENTS.md files and skill files.
File: packages/coding-agent/src/core/system-prompt.ts L154-165
// Append project context files
if (contextFiles.length > 0) {
prompt += "\n\n# Project Context\n\n";
for (const { path: filePath, content } of contextFiles) {
prompt += `## ${filePath}\n\n${content}\n\n`;
}
}
File: packages/coding-agent/src/core/skills.ts L339-364
export function formatSkillsForPrompt(skills: Skill[]): string {
const lines = [
"\n\nThe following skills provide specialized instructions.",
"Use the read tool to load a skill's file when the task matches.",
"",
"<available_skills>",
];
for (const skill of skills) {
lines.push(" <skill>");
lines.push(` <name>${skill.name}</name>`);
lines.push(` <description>${skill.description}</description>`);
lines.push(` <location>${skill.filePath}</location>`);
lines.push(" </skill>");
}
lines.push("</available_skills>");
return lines.join("\n");
}
For a minimal harness, you can skip skills entirely and just read AGENTS.md from the working directory if it exists.
