eSkill

eSkill is the skill and workflow layer of the eAgent platform. It composes eMCP server tools into higher-level workflows — where eMCP provides primitives (git_log, ast_search, sql_query), eSkill provides orchestration (changelog generation, codebase cartography, deployment checklists).

11 plugins. 90 skills. 3 hooks. Local-only, MIT-licensed.

Architecture

eMCP (primitives)                       eSkill (orchestration)
────────────────────────────────        ────────────────────────────────
git_log + git_show                   -> e-changelog
git_diff + lsp_references + ast      -> e-review
ast_search + ast_rewrite + test      -> e-refactor
pdf_read_text + docx_read_html       -> e-doc
lsp_symbols + ast_search + diagram   -> e-diagram
docker_ps + docker_logs + log_*      -> e-containers
docs_search + think_* + fetch_url    -> e-research
crypto_hash_file + archive_create    -> e-backup
ast_search + lsp_diagnostics         -> e-scan

eMCP exposes 31 servers (plus 2 composites) with 174 tools. eSkill's 90 skills call sequences of those tools in deliberate order, handle edge cases, and produce structured output. A skill that composes eMCP tools into a workflow is the intended design. A skill that reimplements what an eMCP server already provides is waste.

Installation

eSkill is consumed by the eAgent runtime. Skills are loaded from the plugins/ directory structure. See the eAgent documentation for integration details.

Design Principles

• eMCP-complementary. Skills compose eMCP server tools into workflows. They do not reimplement what eMCP already provides.
• Local-only. No SaaS dependencies or API keys. Everything runs on the local machine.
• Cross-platform. Windows, macOS, Linux. Forward slashes in all paths.
• Minimal. No decorative language, no unnecessary abstraction.
