AGH gives teams one place to publish, version, assign, and pull reusable agent instructions and skills into their repos.

Use it when agent guidance needs the same discipline as infrastructure: reproducible changes, clear ownership, and self-hosted runtime. AGH is early, Docker-first, and published as a PyPI package, Homebrew formula, and GHCR server image.

• Centralize guidance: publish shared AGENTS.md, CLAUDE.md, and skill files once.
• Version every change: packages are immutable SemVer releases assigned to projects.
• Keep repos deterministic: each workspace records .agh/lock.toml and applies only the selected agent target.
• Run it yourself: host the server with Docker, SQLite, and persistent /data storage.

Install

Linux / macOS:

brew install giulianotesta7/tap/agh

Windows (Scoop):

scoop bucket add agh https://github.com/giulianotesta7/scoop-agh
scoop install agh

or install with script:

curl -fsSL https://raw.githubusercontent.com/giulianotesta7/AgentGuidanceHub/main/scripts/install.sh | sh

or install with uv:

uv tool install --force agh

from a checkout:

git clone https://github.com/giulianotesta7/AgentGuidanceHub.git
cd AgentGuidanceHub
uv tool install --force .

check the CLI:

agh --help

Run the server with the published Docker image:

docker compose up -d
curl http://127.0.0.1:8912/api/v1/health

The default Compose image is:

ghcr.io/giulianotesta7/agent-guidance-hub:${AGH_IMAGE_TAG:-latest}

Pin production deployments with a release tag:

AGH_IMAGE_TAG=0.2.0 docker compose up -d

Quick start

Read the first owner token on the host running AGH:

docker run --rm -v agh-data:/data busybox \
  cat /data/secrets/initial_owner_token

Then log in from your machine:

agh login \
  --url <instance-url> \
  --email [e-mail] \
  --token "<initial-owner-token>"

Check the saved config. AGH masks the token:

agh config show

Create a project with the repo URL developers use in git remotes:

agh project create "Agent Guidance Hub" \
  --repo-url https://github.com/giulianotesta7/AgentGuidanceHub.git

Work from a linked repo:

agh sync
agh agent select opencode # or: agh agent select claude
agh pull --dry-run
agh pull
agh agent
agh agent show

Piece	What it does
Packages	Shared instructions, skills, or both. Published versions are immutable.
Projects	One git repository plus the package versions it should use.
Workspaces	A local repo linked with agh sync, one selected agent, and a committed lockfile.

Package authoring

A package starts with this shape:

my-package/
├── agh.package.toml
├── instructions/
│   ├── AGENTS.md
│   └── CLAUDE.md
└── skills/
    └── reviewer/
        └── SKILL.md

Create a template:

agh package init ./my-package --domain acme --name onboarding --version 1.0.0

The manifest starts as:

domain = "acme"
name = "onboarding"
version = "1.0.0"
description = "TODO"

Useful starter flags:

• --with-agents creates instructions/AGENTS.md.
• --with-claude creates instructions/CLAUDE.md.
• --with-skill NAME creates skills/NAME/SKILL.md.

Allowed files:

• agh.package.toml
• instructions/AGENTS.md
• instructions/CLAUDE.md
• skills/<name>/SKILL.md

Rules:

• A package can contain instructions, skills, or both.
• It must include at least one instruction file or skill.
• version must be exact SemVer, such as 1.0.0.
• Published versions are immutable. Publish 1.0.1 for changes.
• Do not publish latest. Use latest only when assigning packages to projects.
• Use UTF-8 text files. Do not include symlinks.

Publish and list packages:

agh package publish ./my-package
agh package list

Example publish output:

Published acme/onboarding@1.0.0.
Package ID: pkg_...
Checksum: sha256:...

Project assignment

A project is an AGH record linked to one git repository.

agh project create "Agent Guidance Hub" \
  --repo-url https://github.com/giulianotesta7/AgentGuidanceHub.git
agh project list
agh project get prj_...
agh project update prj_... --name "App API"
agh project delete prj_...

Project commands that take a project reference accept prj_... ids or exact project names. All-digit values are treated as ids, and project names cannot contain only digits.

Assign packages interactively or directly:

agh project package add
agh project package add prj_...
agh project package add prj_... acme/onboarding@latest
agh project package add prj_... onboarding@1.0.0
agh project package list prj_...
agh project package update prj_... asn_... --package-ref acme/onboarding@1.0.0
agh project package remove prj_... asn_...

• agh project package add guides you through project selection, unassigned package selection, and confirmation.
• agh project package add <project> skips project selection, shows unassigned packages for that project, and asks for confirmation.
• agh project package add <project> <package-ref> assigns directly without prompts, which fits scripts and CI.

asn_... identifies the project-to-package assignment. Package inputs accept pkgv_..., domain/name@version, and exact name@version refs. No-domain refs must match a single package domain, otherwise AGH reports a conflict. Use an exact version to pin the project. Use latest with domain-qualified refs when the project should resolve to the newest published version during pull.

During workspace pull, AGH writes the resolved concrete version and checksum to .agh/lock.toml.

Collection administration

Collections group skill-only packages that members install through agh skill .... Owners and admins manage collections with the agh collection commands. These admin commands are separate from the consumer agh skill ... flow.

agh collection create "Team Skills" --description "Shared review skills"
agh collection list
agh collection get "Team Skills"
agh collection update "Team Skills" --name "Review Skills"
agh collection delete "Review Skills"

Collection commands that take a collection reference accept col_... ids or exact active collection names. Canonical ids skip name resolution; exact names resolve through the active-collection by-name endpoint.

Assign skill-only packages to a collection:

agh collection package list "Team Skills"
agh collection package add "Team Skills" acme/reviewer@latest
agh collection package add "Team Skills" acme/reviewer@latest --position 2
agh collection package update "Team Skills" casn_... --package-ref acme/reviewer@1.0.0 --inactive
agh collection package remove "Team Skills" casn_...

casn_... identifies the collection-to-package assignment. Collection packages must be skill-only: AGH rejects packages that contain instructions/AGENTS.md, instructions/CLAUDE.md, or no skills, and the CLI surfaces that server validation. Package inputs accept pkgv_..., domain/name@version, and exact name@version refs. Unlike agh project package add, agh collection package add requires both the collection and the package reference — there is no interactive picker, since only the server can validate skill-only packages.

Global skills

Global skills are collection-backed tools installed into the selected agent's native user-level skill directory. A collection is an AGH-managed group of skill-only packages made available by the server; global skills are separate from workspace package assignments.

Command	What it does
agh skill list	Lists skills available from active collections.
agh skill install acme/commenting@latest reviewer	Resolves, downloads, and installs reviewer globally for the selected agent.
agh skill remove reviewer	Removes the global install for the selected or default agent.
agh skill installed	Lists locally installed global skills from the global-skill lock for the selected or default agent.
agh skill agent show	Shows the saved default agent for global skill commands.
agh skill agent select opencode	Saves OpenCode as the default for global skill commands.
agh skill agent clear	Clears the global skill default agent.

If no default is saved and --agent is omitted, AGH prompts with:

Select the agent for global skills:

Install paths:

• OpenCode global skills: ~/.config/opencode/skills
• Claude global skills: ~/.claude/skills

Global skill state is local user state under XDG_STATE_HOME/agh or ~/.local/state/agh; it does not change workspace pull behavior or .agh/lock.toml. If a remove operation reports a filesystem recovery error, follow the command output: the lock and native skill file may need manual cleanup before retrying.

Workspace pull and Git state

Command	What it does
agh sync	Matches the git remote to an AGH project and writes .agh/project.toml.
agh agent / agh agent show	Shows Claude Code/OpenCode availability and the current local selection.
agh agent select claude	Selects Claude Code for this workspace.
agh agent select opencode	Selects OpenCode for this workspace.
agh agent clear	Removes the local workspace agent selection.
agh pull --dry-run	Fetches the server plan without writing repo files.
agh pull	Applies instructions and skills for the selected agent and writes .agh/lock.toml.
agh pull --force	Replaces conflicted AGH blocks or skill targets.

There is no both option. If no agent is selected, interactive agh pull asks which agent to use. Skip exits with code 2 and writes nothing.

Instruction files use managed blocks:

<!-- AGH-BEGIN package="<package-ref>" artifact="instructions/AGENTS.md" checksum="sha256:..." -->
Project instructions from AGH live here.
<!-- AGH-END package="<package-ref>" -->

If you edit inside the block, the next agh pull exits with conflict code 3. Use agh pull --force when AGH should replace it.

Skills go where agents already look:

.claude/skills/<skill>/SKILL.md
.opencode/skills/<skill>/SKILL.md

AGH tries a relative symlink to .agh-cache/packages/.... If the OS rejects symlinks, AGH copies the file. The lockfile records the mode:

[[packages]]
package_ref = "acme/onboarding@1.0.0"

[[artifacts]]
package_ref = "acme/onboarding@1.0.0"
path = "skills/reviewer/SKILL.md"
target_path = ".opencode/skills/reviewer/SKILL.md"
mode = "symlink" # or mode = "copy"
source = ".agh-cache/packages/acme/onboarding/1.0.0/skills/reviewer/SKILL.md"

Commit shared workspace state:

• .agh/project.toml
• .agh/lock.toml
• generated AGENTS.md / CLAUDE.md when your team wants those reviewed
• generated .claude/skills/ or .opencode/skills/ when your team wants skills reviewed

Do not commit local cache state:

.agh-cache/

AGH downloads packages to .agh-cache/packages/ and stores each developer's agent choice in .agh-cache/preferences.toml. If skill targets are symlinks, a fresh clone needs agh pull to rebuild the cache before those links resolve.

Exit codes:

Code	Meaning
0	Success or no changes.
1	Runtime/API/download failure.
2	Local validation, malformed manifest, or missing/skipped agent selection.
3	Conflict.
4	Authentication/authorization failure.
5	Workspace is not linked; run agh sync.

Server operations

The first owner token is written once:

/data/secrets/initial_owner_token

Store it. AGH will not show it again. The server stores token hashes, not plaintext tokens.

Role	Use
owner	Full admin access, including bootstrap ownership.
admin	Manage users, projects, packages, and assignments.
member	Day-to-day workspace access.

Admin commands:

agh user list
agh user create [e-mail] --role admin
agh user show [e-mail]
agh user update usr_... --role member
agh user delete usr_...
agh token rotate
agh token reset usr_...
agh config show

User commands that take a user reference accept usr_... ids or exact emails.

agh config show masks the saved token as token = ****.

Runtime state lives under /data:

Path	Purpose
/data/agh.sqlite3	SQLite database.
/data/packages/	Published package payloads.
/data/logs/agh.log	Server log.
/data/secrets/initial_owner_token	First owner token, created once.

The image owns /data as agh:agh (10001:10001) at build time. Named Docker volumes are initialized from that image-owned /data tree. Bind mounts must already be writable by UID/GID 10001:10001; the container does not repair host ownership.

Direct Docker run:

docker run --rm -p 8912:8912 -v agh-data:/data \
  -e AGH_BOOTSTRAP_OWNER_EMAIL=[e-mail] \
  ghcr.io/giulianotesta7/agent-guidance-hub:0.2.0

Healthcheck:

curl http://127.0.0.1:8912/api/v1/health

Backup at least:

/data/agh.sqlite3
/data/packages/
/data/secrets/

Upgrade by pinning the next image tag and restarting:

AGH_IMAGE_TAG=0.2.0 docker compose pull
AGH_IMAGE_TAG=0.2.0 docker compose up -d

Development

uv sync
uv run pytest
uv run uvicorn agh.server.app:app --host 0.0.0.0 --port 8912

Local data uses .agh-data/ by default.
