### Skills (`skills/`)
Discovery and parsing, independent of the agent: `build_roots(config, workspace=…, user_config_dir=…, home=…)` resolves `[skills]` into ordered `SkillRoot`s (`config` explicit paths → `plyngent` user dir → `claude` user/project dirs), `SkillStore` scans each root for directories with a `SKILL.md` (a root may itself be one), parses the frontmatter subset (`frontmatter.py`), and caches the records against the directory list and its `SKILL.md` timestamps. `skills` returns the visible records sorted by name (first root wins), `shadowed()` the losing copies, `find(name)` exact-then-case-insensitive, `default_write_root()` our own directory (or the first root), `reload()` forces a rescan; `resolve_inside` / `resolve_skill_file` keep every read and write inside a skill directory (absolute paths and symlink escapes are refused). Records carry `issues` (unusable declared name, no description, unparseable frontmatter) so a repaired third-party skill stays visible instead of being silently fixed.

### Memory (`memory/`)
@@ -105,7 +105,7 @@ Module-level `@tool` handlers. Call `set_workspace_root()` before use.
- **`net` / `fetch`**: HTTP GET/POST/PUT/DELETE via niquests (isolated session, not the LLM client). Manual redirects with per-hop SSRF checks (`asyncio` `getaddrinfo`). Private/loopback hosts need instance policy grant (CLI timed confirm; **not** YOLO). Public cleartext HTTP and mutating methods soft-confirm (`YOLO`/`TRUSTABLE`). HTTPS→HTTP redirects blocked unless `allow_http_downgrade`. `user_agent` tool arg (or headers) is never replaced by the default when provided. Caps: body bytes/chars, request body size.
- **`net` / `web_search`** (`tools/net/search.py`, `tools/net/bing.py`): the hosted search a DeepSeek provider cannot use, as a local tool. `build_web_search_tool(backends)` closes over the sources named by `provider.search_sources` and asks them **in fallback order** (`search_in_order`): `DeepseekSearchBackend` (one `/messages` turn with the server tool, `lmproto/deepseek/anthropic/search.py`) and/or `BingSearchBackend` (Bing's RSS results, snippets included, fetched through the same client as `fetch`). The handler returns one `title — url` entry per hit (plus the snippet when the source has one); a source that raises or finds nothing is skipped and reported only if every source fails. Registered by the CLI host only when `config.routing.local_web_search` says so: a DeepSeek provider whose `provider_tools` ask for `web_search`, on a surface that ignores hosted tools (`convention` other than `anthropic`), with a non-empty `search_sources`. Tags LOCAL|READ_ONLY.
- **`mcp`** (`tools/mcp.py`): register one server's advertised tools into the catalog as namespaced `mcp__<server>__<tool>` definitions with `ToolSource(kind="mcp", plugin_id=server)`; tags LOCAL (+ READ_ONLY when the server config sets `read_only`) — never YOLO/TRUSTABLE. `register_mcp_tools` purges prior MCP entries then re-registers every connected server (hosts call it on tool-registry rebuild); connections must already be started by `McpManager`.
- **`skills`** (`tools/skills.py`): discovery, reading, and writing of skill directories (`plyngent.skills` owns roots, the `SKILL.md` frontmatter subset, the mtime-cached store, and the inside-the-skill path rule). `skill_list` (names, source root, directory, description, shadowed copies, frontmatter notes), `skill_read` (a `SKILL.md` by name, or one bundled file — reuses `read_file` for ranges/line numbers/`truncate_token`), `skill_search` (regex over every visible skill via `regex_files`, hits rebased on `<skill>/<file>`), `skill_create` (new `SKILL.md` + optional `files`), `skill_edit` (replace / `append` / rewrite one file; a rewritten `SKILL.md` is re-parsed and notes a lost description). Reads need no grant (the host publishes the roots as `WorkspacePolicy.static_read`, so `read_file`/`regex_files` see them while writes stay denied); writes go through **`SkillWritePolicy`** on the instance — denylist first, then `SessionState.skill_write_roots` (a `session` answer), then `[skills].allow_write`, then the host's confirm hook (CLI `prompt_skill_write_confirm`: `o`nce/`s`ession/`n`o, timed, default deny, **not** skipped by YOLO); a host with no hook denies. Grants are per **skill directory**; `[skills].enabled = false` drops the tools from the registry (`SKILL_TOOL_NAMES`).
- **`skills`** (`tools/skills.py`): discovery, reading, and writing of skill directories (`plyngent.skills` owns roots, the `SKILL.md` frontmatter subset, the uncached store, and the inside-the-skill path rule). `skill_list` (names, source root, directory, description, shadowed copies, frontmatter notes), `skill_read` (a `SKILL.md` by name, or one bundled file — reuses `read_file` for ranges/line numbers/`truncate_token`), `skill_search` (regex over every visible skill via `regex_files`, hits rebased on `<skill>/<file>`), `skill_create` (new `SKILL.md` + optional `files`), `skill_edit` (replace / `append` / rewrite one file; a rewritten `SKILL.md` is re-parsed and notes a lost description). Reads need no grant (the host publishes the roots as `WorkspacePolicy.static_read`, so `read_file`/`regex_files` see them while writes stay denied); writes go through **`SkillWritePolicy`** on the instance — denylist first, then `SessionState.skill_write_roots` (a `session` answer), then `[skills].allow_write`, then the host's confirm hook (CLI `prompt_skill_write_confirm`: `o`nce/`s`ession/`n`o, timed, default deny, **not** skipped by YOLO); a host with no hook denies. Grants are per **skill directory**; `[skills].enabled = false` drops the tools from the registry (`SKILL_TOOL_NAMES`).
- **`DEFAULT_TOOLS` / catalog**: access + file + process + vcs + chat + todo + skills + net (`fetch`) for local surface. `ToolTag.READ_ONLY` marks non-mutating tools (`read_file`, `get_truncated`, `listdir`, `glob_paths`, `regex_files`, `tree`, `todo_list`, `wait`, `ask_user_*`, `vcs_*`, `skill_list`/`skill_read`/`skill_search`, `fetch`); `ToolRegistry.clone(read_only_only=True)` selects just those for safe side turns / planning, and `read_only_context()` (in `tools/context.py`) makes `fetch` accept GET only.

Click app + readline REPL. Entry: `plyngent` / `python -m plyngent`.
- **`plyngent chat`**: provider/model (flags or interactive; Tab via readline in `prompting`); sessions store `provider_name`/`model` and restore on resume; SQLite via `[database]` (file DB under user data when url unset; explicit `url = ":memory:"` kept + warn); workspace-bound; resume latest for cwd/`--workspace` by default (`--new` / `--session`). One-shot: `-p/--prompt` and non-TTY stdin; exit codes 0/1/2/3; `--yes` (YOLO on), `--auto-continue` (auto-raise limits), `--stream/--no-stream`, `--quiet`. Root `--log-level`. Enabled `[mcp]` servers start before the REPL (`_start_mcp_manager`, per-server failures warn on stderr) and are closed on exit (`McpManager.aclose`); each server spawns in its own session/process group (`start_new_session` / `CREATE_NEW_PROCESS_GROUP`), so a terminal Ctrl+C does not kill it.

- `/btw` side questions: forked session; main transcript/DB untouched. `--tools=read` (default) exposes only `READ_ONLY` tools under `read_only_context()` (fetch=GET) with the main session view; `--tools=no` off; `--tools=full` whole-registry clone with fresh session. Tools off: default falls back to no tools; explicit `read`/`full` errors. The model gets an `aside` notice as its last message before the question (unsaved exchange + tool scope), shown to the user as `[notice] aside: …`.
- Explicit `/resume` or `--session` from another workspace prompts: **keep** / **update** / **abort**. A session resumed by a **freshly started process** (`--session` / default latest) also gets a `resume` notice about what a restart drops (PTY sessions, running commands, temp workspaces) — resuming inside a live process pushes nothing.
- Host notices (`agent/notices.py`): system-level messages appended as trailing `developer` rows, never system-prompt edits — `Notice.to_message()` for the model, `.summary` for the user via `cli.display.echo_notice` (`--quiet` hides the user line only). Durable hosts persist them (`ChatAgent.push_notice`); a side agent without memory keeps its notice local. Trailing developer messages never end a turn, so `/retry` still sees an interrupted turn behind a notice or checkpoint.
