# 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, async runtime via tokio) and `crates/agentspec-sdk` (a standalone SDK for bootstrapping AI-powered CLI tools — config and CLI scaffolding helpers; not consumed by the binary).
-
- Key layers (all paths relative to `crates/agentspec/`):
-
- | Layer | Path | Role |
- |-------|------|------|
- | IR | `src/ir.rs` | Canonical `Resource` type + 8 `ResourceKind`s (Skill, Agent, ProjectConfig, InstructionFile, LlmsTxt, Memory, Session, Plan) -- all vendor formats convert to/from this |
- | Adapters | `src/adapters/` | Vendor-specific parsers/emitters (agentskills, claude, gemini, agents_md, claude_md, instruction_file, llms_txt) |
- | Tools | `src/tools/mod.rs` | `CodingTool` trait + macro-defined impls for 11 AI tools |
- | MCP | `src/mcp.rs` | Canonical MCP server store (`~/.agents/mcp/`) + injection into tool configs |
- | Session | `src/session/` | Read adapters + session IR + markdown render + cross-tool sync |
- | Settings/JSON | `src/jsonfile.rs` | Sentinel-keyed JSON edits backing MCP + permissions config writes |
- | Inventory | `src/inventory.rs` | LIVE store: `Config` + `TrackedResource`, SHA-256 hashing |
- | Project files | `src/project_files.rs` | Project config / instruction-file discovery and readiness |
- | Ops | `src/ops/` | One module per command (create, dedup, discover, hooks, link, list, manage, memory, permissions, plans, plugins, project_sync, prune, refresh, remove, sync, validate, verify) |
- | TUI | `src/tui/screens/` | ratatui screens (skill/agent/tool/session/memory/config lists + preview, link-picker, and delete-confirm modals) |
- | CLI | `src/cli.rs` | clap derive command definitions |
- | Lock | `src/lockfile.rs` | LEGACY `.skill-lock.json` v3 serde (migration-only; superseded by the live inventory) |
-
- ## Key Files
-
- All under `crates/agentspec/`:
+ 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).
- - `src/ir.rs` -- the canonical IR that all adapters target
- - `src/adapters/mod.rs` -- `Adapter` trait definition
- - `src/tools/mod.rs` -- `CodingTool` trait + `define_tool!` macro
- - `src/ops/link.rs` -- symlink creation, relative path computation, link reconciliation
- - `src/ops/sync.rs` -- full pipeline (discover, adopt, reconcile, link, verify)
- - `src/ops/manage.rs` -- `manage add` source resolution (local path, git URL, owner/repo)
- - `src/inventory.rs` -- `Config` struct, `TrackedResource`, SHA-256 hashing
- - `src/tui/app.rs` -- TUI state machine
+ 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`. 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/`, and sentinel-keyed JSON settings edits (MCP, permissions) in `jsonfile.rs`. 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 relative symlinks pointing into the shared store.
**`manage add <source> --all-tools`** resolves the source (local path, `owner/repo`, or git URL with optional `#branch@subpath`), copies to shared store, then creates symlinks in every installed tool's directory. Existing names are skipped (first-installed wins).
**`sync`** runs a 3-phase pipeline:
1. **Reconcile** -- adopts existing symlinks on disk that aren't tracked in config (handles links created by older versions or external tools)
2. **Link** -- creates missing symlinks for managed resources not yet present in tool directories
3. **Verify** -- checks SHA-256 hashes against stored values to detect external modifications
**Relative symlinks** are computed via `pathdiff::diff_paths()` so they survive home directory moves. Example: `~/.claude/skills/my-skill` -> `../../.agents/skills/my-skill`.
**Copy fallback** via `--copy` flag for filesystems that don't support symlinks.
## 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`, `update`, `version`. The only output-format flag is the global `--format human|json` (default `human`).
## 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
