+ +# Skill Router + +Skill Router indexes a repository's `SKILL.md` skills and recommends the smallest relevant skill set for a task. It is a **router, not an executor**: the agent receives a deterministic recommendation, checks it against the task, loads the selected skill, and decides what to do. + +## Why it exists + +As a skill library grows, reading every skill on every request wastes context and makes overlapping skills difficult to distinguish. Skill Router keeps compact generated metadata in a routing manifest, filters candidates cheaply, ranks the candidates using structured signals, and returns one of three safe outcomes: + +- `route` — a clear skill (or minimal ordered plan) is recommended. +- `ambiguous` — candidates are too close; the agent should ask for clarification. +- `no_route` — no installed skill is relevant; handle the task normally. + +## How it works + +```mermaid +flowchart TD + A[User task] --> B[Coding agent] + B --> C[Skill Router] + C --> D[Generated routing manifest] + D --> E[Candidate filtering and ranking] + E --> F{Decision} + F -->|route| G[Selected SKILL.md] + F -->|ambiguous| H[Ask user] + F -->|no_route| I[Handle directly] + G --> B +``` + +Routing reads generated metadata rather than the full skill library. The selected `SKILL.md` is loaded only after routing. The router never runs a returned command. + +## Features + +- Two-stage, deterministic routing with `route`, `ambiguous`, and `no_route` decisions. +- Positive and negative boundaries (`use_when` and `not_when`) for near-neighbor skills. +- Structured matching across intents, objects, actions, capabilities, aliases, and domains. +- Minimal ordered multi-skill plans for genuinely separate task dimensions. +- Generated registry and routing manifest with fingerprint-based cache invalidation. +- Conservative bootstrap for existing or empty agent repositories. +- Validation, drift detection, debug scoring, and a gold-set benchmark. +- Agent-neutral `SKILL.md` core with selectable agent directory layouts. + +## Supported agents and layouts + +Skill Router's skill package uses the portable directory format `skill-router/SKILL.md` with YAML frontmatter containing `name` and `description`. The routing engine itself is agent-neutral. + +| Environment | Project skill directory | User-level directory | Status | +|---|---|---|---| +| Generic `SKILL.md` agents | `.agents/skills/` | `~/.agents/skills/` | Implemented and tested by the installer | +| Claude Code | `.claude/skills/` | `~/.claude/skills/` (manual copy) | Layout addressed; project installer supported | +| DeepSeek Harness | `.dsh/skills/` | `~/.agents/skills/` | Layout addressed; project installer supported | + +Claude Code and DeepSeek Harness consume the same `SKILL.md` contract; Skill Router does not claim an agent-specific plugin or native command integration. DeepSeek Harness also recognizes `.agents/skills/`; its project-local `.dsh/skills/` directory is available through `--agent deepseek`. If your agent uses another location, use `--agent generic` and copy the generated package into that agent's documented skill directory. + +## Requirements + +- Python 3.10 or newer (standard library only; no third-party dependencies). +- A coding agent that can discover directory-based `SKILL.md` skills. +- On Windows, use `py` in place of `python3` when needed. + +## Quick start + +From a clone of this repository: + +```bash +python3 install.py +# Choose 1 (Global) or 2 (Project) before anything is written. +``` + +Then verify the installed CLI. The installer prints the exact path; the forms are: + +```bash +# project installation +python3 .skill-router/skill.py --version +python3 .skill-router/skill.py doctor --root . + +# global installation +python3 ~/.skill-router/skill.py --version +# Diagnose a particular agent repository with the global CLI: +python3 ~/.skill-router/skill.py doctor --root /path/to/agent-repo +``` + +A successful `doctor` report has `"ok": true`. For a project that already contains skills, initialize its generated metadata first: + +```bash +python3 .skill-router/skill.py bootstrap --root . +python3 .skill-router/skill.py validate --root . +``` + +Start a new agent session after installing so it can rediscover the skill directory. + +## Installation + +The installer shows the scope, agent layout, and every destination **before** it changes the filesystem. It refuses to overwrite an existing file unless `--upgrade` is explicit. + +### Global installation + +Global installation places the skill at `~/.agents/skills/skill-router/` (or `~/.claude/skills/skill-router/` with `--agent claude`) and the CLI at `~/.skill-router/skill.py`. This makes the skill available to compatible projects for the current user. It does not edit `PATH`, shell profiles, agent settings, or unrelated skill files. + +```bash +python3 install.py --scope global --agent generic +# non-interactive / CI-friendly confirmation: +python3 install.py --scope global --agent generic --yes +``` + +Use `--agent claude` for Claude Code's native project or user layout. The default `generic` and `deepseek` choices use the shared `~/.agents/skills` location. + +### Project installation + +Project installation writes only inside the selected project: + +```bash +python3 install.py --scope project --agent generic --project /path/to/project +python3 install.py --scope project --agent claude --project /path/to/project +python3 install.py --scope project --agent deepseek --project /path/to/project +``` + +The project layout has higher practical precedence than the same user's global skill in agent implementations that support both scopes. Skill Router itself does not merge or execute skills; the host agent owns duplicate resolution. Keep one project copy when deterministic behavior matters. + +### Upgrade and uninstall + +Both operations are explicit and previewable. They affect only the three Skill Router files shown by the installer: + +```bash +python3 install.py --scope project --upgrade --yes +python3 install.py --scope project --uninstall +``` + +For global operation, add `--scope global`. If an existing destination is not a Skill Router file, installation stops instead of overwriting it. + +## First usage + +For an existing skill repository, bootstrap once, then synchronize after every skill change: + +```bash +python3 skill.py bootstrap --root /path/to/agent-repo +python3 skill.py sync --root /path/to/agent-repo +python3 skill.py route "check the accessibility of our dashboard against wcag" \ + --root /path/to/agent-repo +``` + +The route response is JSON. It includes the decision, selected skill, validated command, confidence, and evidence. Add `--debug` for candidate scores and penalties. The router recommends; the host agent must sanity-check the selected skill before loading or executing anything. + +## Examples + +### One clear match + +```bash +python3 skill.py route "scan our login endpoint for vulnerabilities" --root ./agent-repo +# decision: route -> security-review +``` + +### Overlapping candidates + +```bash +python3 skill.py route "review my writing" --root ./agent-repo +# decision: ambiguous; ask whether the user wants grammar, style, or human-like prose review +``` + +### Multi-skill work + +```bash +python3 skill.py route "write a readme and draft the marketing blurb for the api" \ + --root ./agent-repo +# decision: route; ordered skills include docs-writing and copywriting +``` + +### Project scope + +```bash +python3 install.py --scope project --agent generic --project . +python3 .skill-router/skill.py bootstrap --root . +python3 .skill-router/skill.py route "write a README for this API" --root . +``` + +## Skill discovery and adding skills + +The source of truth is a directory under `/skills//` containing `SKILL.md` and `manifest.json`. A skill manifest must register only commands that really exist. Routing boundaries make selection safer: + +```json +{ + "name": "my-skill", + "description": "Reviews database migrations.", + "use_when": ["review a database migration"], + "not_when": ["review frontend visual design"], + "objects": ["database", "schema"], + "actions": ["review"] +} +``` + +Copy `templates/manifest.json`, fill in the metadata, and run: + +```bash +python3 skill.py sync --root . +python3 skill.py validate --root . +python3 skill.py route "review this database migration" --root . --debug +``` + +`skill-registry/registry.json` and `skill-registry/routing-manifest.json` are generated artifacts. Do not edit them by hand. Project manifests are authoritative; project-generated metadata is intentionally separate from user-global metadata. + +When several skills match, the router uses explicit boundaries and structured scores. A clear winner returns `route`; a near tie returns `ambiguous`; separate strong dimensions may produce a minimal ordered plan. It never silently executes the plan. + +## Configuration + +Defaults live in `CONFIG` in `skill.py`. To override supported values without editing code, set `SKILL_ROUTER_CONFIG` to a JSON file: + +```json +{"route_floor": 0.50, "ambiguity_gap": 0.12, "max_candidates": 20} +``` + +```bash +SKILL_ROUTER_CONFIG=/path/to/router-config.json python3 skill.py route "..." --root . +``` + +The environment configuration is process-local and overrides built-in defaults. There is no checked-in global/project config merger. Use the same environment variable in the agent process if a project needs an override. `--no-cache` bypasses the route cache for one request. + +## Directory structure + +```text +. +├── SKILL.md # agent-facing skill instructions +├── skill.py # routing engine and CLI +├── install.py # safe global/project installer +├── manifest.json # this skill's metadata +├── skills// # installed skill sources (in target repos) +├── skill-registry/ # generated indexes (in target repos) +├── templates/ # manifest and agent contract templates +├── benchmarks/ # corpus, gold set, benchmark runner +├── docs/ # detailed documentation +├── tests/ # regression tests +└── assets/icon/ # official supplied artwork +``` + +For detailed documentation, see [`docs/`](docs/). + +## Troubleshooting + +| Symptom | Check | +|---|---| +| `doctor` reports missing metadata | Run `bootstrap --root ` then `sync`. | +| A new skill is not routed | Ensure its folder has `manifest.json`, add routing boundaries, then run `sync`. | +| `validate` reports drift | Do not edit generated JSON; run `sync` after changing a manifest. | +| Install refuses to overwrite | Inspect the displayed destination; use `--upgrade` only for a known Skill Router install. | +| Agent cannot see the skill | Confirm the directory for that agent, restart the session, and use `doctor` for the CLI root. | +| Windows command not found | Use `py install.py` and `py .skill-router\\skill.py ...`. | + +## Development and testing + +Run the complete stdlib-only regression suite: + +```bash +python3 tests/run_tests.py +``` + +Run the benchmark and inspect the generated decision output: + +```bash +python3 skill.py benchmark +python3 skill.py route "review this pull request for unnecessary complexity" --debug +``` + +The tests cover positive and negative routing, ambiguity, no-route, multi-skill plans, cache invalidation, drift, V1 manifest compatibility, bootstrap idempotency, CLI smoke paths, validation exit codes, and benchmark execution.

The router never runs a returned command. - -## Features - -- Two-stage, deterministic routing with `route`, `ambiguous`, and `no_route` decisions. -- Positive and negative boundaries (`use_when` and `not_when`) for near-neighbor skills. -- Structured matching across intents, objects, actions, capabilities, aliases, and domains. -- Minimal ordered multi-skill plans for genuinely separate task dimensions. -- Generated registry and routing manifest with fingerprint-based cache invalidation. -- Conservative bootstrap for existing or empty agent repositories. -- Validation, drift detection, debug scoring, and a gold-set benchmark. -- Agent-neutral `SKILL.md` core with selectable agent directory layouts. - -## Supported agents and layouts - -Skill Router's skill package uses the portable directory format `skill-router/SKILL.md` with YAML frontmatter containing `name` and `description`. The routing engine itself is agent-neutral. - -| Environment | Project skill directory | User-level directory | Status | -|---|---|---|---| -| Generic `SKILL.md` agents | `.agents/skills/` | `~/.agents/skills/` | Implemented and tested by the installer | -| Claude Code | `.claude/skills/` | `~/.claude/skills/` (manual copy) | Layout addressed; project installer supported | -| DeepSeek Harness | `.dsh/skills/` | `~/.agents/skills/` | Layout addressed; project installer supported | - -Claude Code and DeepSeek Harness consume the same `SKILL.md` contract; Skill Router does not claim an agent-specific plugin or native command integration. DeepSeek Harness also recognizes `.agents/skills/`; its project-local `.dsh/skills/` directory is available through `--agent deepseek`. If your agent uses another location, use `--agent generic` and copy the generated package into that agent's documented skill directory. - -## Requirements - -- Python 3.10 or newer (standard library only; no third-party dependencies). -- A coding agent that can discover directory-based `SKILL.md` skills. -- On Windows, use `py` in place of `python3` when needed. - -## Quick start - -From a clone of this repository: - -```bash -python3 install.py -# Choose 1 (Global) or 2 (Project) before anything is written. -``` - -Then verify the installed CLI. The installer prints the exact path; the forms are: - -```bash -# project installation -python3 .skill-router/skill.py --version -python3 .skill-router/skill.py doctor --root . - -# global installation -python3 ~/.skill-router/skill.py --version -# Diagnose a particular agent repository with the global CLI: -python3 ~/.skill-router/skill.py doctor --root /path/to/agent-repo -``` - -A successful `doctor` report has `"ok": true`. For a project that already contains skills, initialize its generated metadata first: - -```bash -python3 .skill-router/skill.py bootstrap --root . -python3 .skill-router/skill.py validate --root . -``` - -Start a new agent session after installing so it can rediscover the skill directory. - -## Installation - -The installer shows the scope, agent layout, and every destination **before** it changes the filesystem. It refuses to overwrite an existing file unless `--upgrade` is explicit. - -### Global installation - -Global installation places the skill at `~/.agents/skills/skill-router/` (or `~/.claude/skills/skill-router/` with `--agent claude`) and the CLI at `~/.skill-router/skill.py`. This makes the skill available to compatible projects for the current user. It does not edit `PATH`, shell profiles, agent settings, or unrelated skill files. - -```bash -python3 install.py --scope global --agent generic -# non-interactive / CI-friendly confirmation: -python3 install.py --scope global --agent generic --yes -``` - -Use `--agent claude` for Claude Code's native project or user layout. The default `generic` and `deepseek` choices use the shared `~/.agents/skills` location. - -### Project installation - -Project installation writes only inside the selected project: - -```bash -python3 install.py --scope project --agent generic --project /path/to/project -python3 install.py --scope project --agent claude --project /path/to/project -python3 install.py --scope project --agent deepseek --project /path/to/project -``` - -The project layout has higher practical precedence than the same user's global skill in agent implementations that support both scopes. Skill Router itself does not merge or execute skills; the host agent owns duplicate resolution. Keep one project copy when deterministic behavior matters. - -### Upgrade and uninstall - -Both operations are explicit and previewable. They affect only the three Skill Router files shown by the installer: - -```bash -python3 install.py --scope project --upgrade --yes -python3 install.py --scope project --uninstall -``` - -For global operation, add `--scope global`. If an existing destination is not a Skill Router file, installation stops instead of overwriting it. - -## First usage - -For an existing skill repository, bootstrap once, then synchronize after every skill change: - -```bash -python3 skill.py bootstrap --root /path/to/agent-repo -python3 skill.py sync --root /path/to/agent-repo -python3 skill.py route "check the accessibility of our dashboard against wcag" \ - --root /path/to/agent-repo -``` - -The route response is JSON. It includes the decision, selected skill, validated command, confidence, and evidence. Add `--debug` for candidate scores and penalties. The router recommends; the host agent must sanity-check the selected skill before loading or executing anything. - -## Examples - -### One clear match - -```bash -python3 skill.py route "scan our login endpoint for vulnerabilities" --root ./agent-repo -# decision: route -> security-review -``` - -### Overlapping candidates - -```bash -python3 skill.py route "review my writing" --root ./agent-repo -# decision: ambiguous; ask whether the user wants grammar, style, or human-like prose review -``` - -### Multi-skill work - -```bash -python3 skill.py route "write a readme and draft the marketing blurb for the api" \ - --root ./agent-repo -# decision: route; ordered skills include docs-writing and copywriting -``` - -### Project scope - -```bash -python3 install.py --scope project --agent generic --project . -python3 .skill-router/skill.py bootstrap --root . -python3 .skill-router/skill.py route "write a README for this API" --root . -``` - -## Skill discovery and adding skills - -The source of truth is a directory under `/skills//` containing `SKILL.md` and `manifest.json`. A skill manifest must register only commands that really exist. Routing boundaries make selection safer: - -```json -{ - "name": "my-skill", - "description": "Reviews database migrations.", - "use_when": ["review a database migration"], - "not_when": ["review frontend visual design"], - "objects": ["database", "schema"], - "actions": ["review"] -} -``` - -Copy `templates/manifest.json`, fill in the metadata, and run: - -```bash -python3 skill.py sync --root . -python3 skill.py validate --root . -python3 skill.py route "review this database migration" --root . --debug -``` - -`skill-registry/registry.json` and `skill-registry/routing-manifest.json` are generated artifacts. Do not edit them by hand. Project manifests are authoritative; project-generated metadata is intentionally separate from user-global metadata. - -When several skills match, the router uses explicit boundaries and structured scores. A clear winner returns `route`; a near tie returns `ambiguous`; separate strong dimensions may produce a minimal ordered plan. It never silently executes the plan. - -## Configuration - -Defaults live in `CONFIG` in `skill.py`. To override supported values without editing code, set `SKILL_ROUTER_CONFIG` to a JSON file: - -```json -{"route_floor": 0.50, "ambiguity_gap": 0.12, "max_candidates": 20} -``` - -```bash -SKILL_ROUTER_CONFIG=/path/to/router-config.json python3 skill.py route "..." --root . -``` - -The environment configuration is process-local and overrides built-in defaults. There is no checked-in global/project config merger. Use the same environment variable in the agent process if a project needs an override. `--no-cache` bypasses the route cache for one request. - -## Directory structure - -```text -. -├── SKILL.md # agent-facing skill instructions -├── skill.py # routing engine and CLI -├── install.py # safe global/project installer -├── manifest.json # this skill's metadata -├── skills// # installed skill sources (in target repos) -├── skill-registry/ # generated indexes (in target repos) -├── templates/ # manifest and agent contract templates -├── benchmarks/ # corpus, gold set, benchmark runner -├── docs/ # detailed documentation -├── tests/ # regression tests -└── assets/icon/ # official supplied artwork -``` - -For detailed documentation, see [`docs/`](docs/). - -## Troubleshooting - -| Symptom | Check | -|---|---| -| `doctor` reports missing metadata | Run `bootstrap --root ` then `sync`. | -| A new skill is not routed | Ensure its folder has `manifest.json`, add routing boundaries, then run `sync`. | -| `validate` reports drift | Do not edit generated JSON; run `sync` after changing a manifest. | -| Install refuses to overwrite | Inspect the displayed destination; use `--upgrade` only for a known Skill Router install. | -| Agent cannot see the skill | Confirm the directory for that agent, restart the session, and use `doctor` for the CLI root. | -| Windows command not found | Use `py install.py` and `py .skill-router\\skill.py ...`. | - -## Development and testing - -Run the complete stdlib-only regression suite: - -```bash -python3 tests/run_tests.py -``` - -Run the benchmark and inspect the generated decision output: - -```bash -python3 skill.py benchmark -python3 skill.py route "review this pull request for unnecessary complexity" --debug -``` - -The tests cover positive and negative routing, ambiguity, no-route, multi-skill plans, cache invalidation, drift, V1 manifest compatibility, bootstrap idempotency, CLI smoke paths, validation exit codes, and benchmark execution.
