# AGENTS.md ## Identity `agentspec` is a Rust CLI + TUI for managing portable agent resources across AI coding tools: skills, agents, MCP servers, sessions, project configs/instruction files, memories, `llms.txt`, plans, permission profiles, hooks, and plugin manifests. ## Architecture Cargo workspace with two published crates: `crates/agentspec` (the CLI + TUI binary, fully synchronous) and `crates/agentspec-sdk` (a standalone SDK for bootstrapping AI-powered CLI tools: config and CLI scaffolding helpers; not consumed by the binary). Anchors, all under `crates/agentspec/src/`: the canonical IR is the `Resource` type and 8 `ResourceKind`s in `ir.rs`; every vendor format converts to/from it through the `Adapter` trait defined in `adapters/mod.rs`. AI tools are described by the `CodingTool` trait and the `define_tool!` macro in `tools/mod.rs`, which also declares each tool's `McpDialect` (where and in what format it stores MCP servers). Live inventory state (`Config`, `TrackedResource`, SHA-256 hashing as the lock) lives in `inventory.rs`; `lockfile.rs` is legacy `.skill-lock.json` serde kept for migration only. Each CLI command maps to one module under `ops/` (clap definitions in `cli.rs`), session read adapters and the session IR live under `session/`, ratatui screens under `tui/screens/`, sentinel-keyed JSON settings edits (permissions) in `jsonfile.rs`, and MCP under `mcp/` (`mod.rs` owns the canonical store and fan-out, `dialect.rs` translates one stored definition into each tool's native format). Use `rg` on a trait or type name to find the matching implementations. ## Linking Mechanism Resources live in the shared store (`~/.agents/skills/`, `~/.agents/agents/`). Tools get real copies of the store version by default; `--symlink` opts into relative symlinks instead. Adoption never modifies or deletes originals: a resource adopted from a non-store location records that location as its `local` source, and `sync` re-copies source -> store -> tool links. **`manage add <source> --all-tools`** resolves the source (local path, `owner/repo`, or git URL with optional `#branch@subpath`), copies to shared store, then copies into every installed tool's directory. Existing names are skipped (first-installed wins). **`sync`** pipeline: 1. **Reconcile** -- adopts existing links on disk that aren't tracked in config (handles links created by older versions or external tools) 2. **Refresh** -- re-copies `local`-sourced resources from their origins into the store 3. **Link** -- creates missing tool copies for managed resources not yet present in tool directories 4. **Verify** -- checks SHA-256 hashes against stored values to detect external modifications **Relative symlinks** (the `--symlink` strategy) are computed via `pathdiff::diff_paths()` so they survive home directory moves. Example: `~/.claude/skills/my-skill` -> `../../.agents/skills/my-skill`. ## Commands ```sh just check # fmt + clippy + test just ci # fmt + clippy + build + test just run # cargo run cargo build # debug build ``` Top-level CLI commands: `manage`, `status`, `sync`, `session`, `project`, `prune`, `mcp`, `plans`, `permissions`, `plugins`, `hooks`, `fleet`, `worktree`, `bootstrap`, `tools`, `commands`, `update`, `version`. The only output-format flag is the global `--format human|json` (default `human`). `bootstrap`, `tools`, and `commands` are the discovery surface: `bootstrap` writes the skills bundled via `include_str!` from `skills/` into the store and links them into every tool, `tools` reports what agentspec sees installed, and `commands` dumps the clap tree (JSON for agents, an indented list for people). Keep `Cli`'s `long_about` in `cli.rs` accurate when the concepts change — it is the first thing both humans and agents read. ## Code Style - Rust 2024 edition - `cargo fmt` + `cargo clippy -- -D warnings` - Conventional commits (enforced by pre-commit hook) - Minimize allocations; prefer `&str` over `String` in function signatures ## Adding a New Vendor Adapter 1. Create `crates/agentspec/src/adapters/<vendor>.rs` 2. Implement the `Adapter` trait (`parse`, `emit`, `validate`) 3. Register in `crates/agentspec/src/adapters/mod.rs` (add a `match` arm in `adapter_for_path()`) 4. Add corresponding `CodingTool` impl in `crates/agentspec/src/tools/mod.rs` via `define_tool!` macro 5. Add an anonymized fixture under `crates/agentspec/tests/fixtures/` and extend the conformance suite (`src/adapters/conformance_tests.rs`, or `src/session/adapters/conformance_tests.rs` for session parsers): a golden snapshot in `tests/snapshots/` plus the `parse(emit(parse(f))) == parse(f)` round-trip case. Snapshot diffs are reviewable contract changes; regenerate deliberately with `INSTA_UPDATE=always cargo test`. ## Adding a New AI Tool 1. Add one line in `crates/agentspec/src/tools/mod.rs` using the `define_tool!` macro 2. Add it to `all_tools()` vec 3. If the tool hosts MCP servers, give it an `mcp:` target. Reuse an existing `McpDialect` when the format matches; a genuinely new format needs a new variant plus read/write/remove arms in `mcp/dialect.rs` and a round-trip test there. Never invent a config path — leave `mcp` unset rather than guessing. ## MCP Dialects One canonical definition per server lives in `~/.agents/mcp/<name>.json` in the `mcpServers` shape. `mcp/dialect.rs` translates it on write and back on read, so `mcp add` fans out to every MCP-capable tool at once. Codex is edited through `toml_edit` so user comments and formatting survive. `mcp doctor` prints the resolved table; `mcp adopt` pulls tool-native servers back into the store.
