agentbundle

The installer for agent-ready-repo. Think npm, but for the skills, subagents, and hooks your coding agent runs on. One pack, one command, every major agent — Claude Code, Codex, Cursor, Copilot, Gemini, and Kiro (both the CLI and the IDE).

Quick start

python -m pip install agentbundle

Requires Python 3.11+. Runs on macOS, Linux, and Windows.

What's new in 0.43.1

agentbundle catalogue init now writes packs/CLAUDE.md and profiles/CLAUDE.md beside the AGENTS.md each already scaffolded. Both hold a single @AGENTS.md import line. Claude Code reads CLAUDE.md rather than AGENTS.md, and finds a nested one only when it reads a file in that directory, so without the pair a Claude session in a new catalogue received no scoped pack or profile guidance at all. Other agents are unaffected: AGENTS.md stays the canonical file and its content did not change.

An existing packs/CLAUDE.md or profiles/CLAUDE.md is never overwritten; init reports the conflict and leaves the file alone.

What's new in 0.43.0

An installed direct skill can now move to a later repository revision with agentbundle upgrade --skill <name>. The command re-runs direct-source admission, shows the same capability consent surface as install, refuses a capability widening, previews writes and removals, and deletes files the new revision dropped before recording the updated row.

Install identity now excludes the repository ref. An install at a different ref still exits 1, but its re-coded refusal names upgrade --skill --source instead of reporting a source collision; a moved source-path now refuses instead of silently self-healing; and a byte-identical reinstall still repairs the projection in place. Remove-then-install is the terminating remediation for the moved-source-path collision.

What's new in 0.42.0

The portable Agent Plugin route now reaches every command that works with distribution routes. validate accepts a pack declaring the per-pack-agent-plugin recipe, render --target agent-plugin selects it, install --emit-install-routes also writes agent-plugins/<pack>/, and install, diff, and upgrade each recognise a portable install. Every surface now reads its route set from the route contract, so a route declared there reaches all of them at once. Published package bytes are unchanged.

What's new in 0.41.1

The same release as 0.41.0, which never reached PyPI: its release run failed a pre-release gate on a faulty performance measurement, so the version exists in the internal repository but was never published here. No shipped code differs between the two.

What's new in 0.41.0

install and validate now accept a skill folder, a skills/ collection, or a single pack taken straight from a repository — no catalogue required. A direct source is admitted against explicit shape and size bounds, pinned to the commit its bytes came from, and summarised for consent before anything is written.

What's new in 0.40.3

Catalogue validation now checks bounded reviewer declarations and keeps their least-privilege posture in supported adapter projections.

What's new in 0.40.2

Catalogue seed lint now accepts the core pack's bounded rule router, cognitive-load topic, and scoped docs guidance. Undeclared seed paths still fail closed.

What's new in 0.40.1

Workspace MCP lifecycle metadata now dispatches briefs to the canonical author-delivery-brief owner. Existing workspace kinds, queues, paths, and lifecycle semantics are unchanged.

What's new in 0.40.0

Catalogue builds now produce offline-validatable Agent Plugins 1.0.0 packages under dist/agent-plugins/<pack>/ for every skills-only pack. The new route preserves canonical skill bytes and executable bits, emits a privacy-minimal root plugin.json, and reports every pack excluded by non-portable primitives. The paired plugin and MCP schemas are bundled from an immutable upstream commit; MCP behavior remains a separate follow-on.

Extension namespaces are closed and allocation-gated. Kiro and Copilot are reserved, while active namespaces must name a versioned schema before their manifest data or files can enter a portable artifact.

What's new in 0.39.4

Codex-projected agents that declare Read, Grep, or Glob without Bash can read and search local files again. AgentBundle now retains Codex's default shell tool for those read intents while confining the agent to a read-only sandbox; write and web capabilities still require their corresponding source declarations.

Kiro IDE and CLI agents may also declare resources: [] to suppress the default skill-resource injection without emitting an empty consumer field. The portable way to say the same thing is Claude Code's own skills: [], which now suppresses that injection too — a non-empty skills list is a build error until skill:// URI templating exists.

Breaking for Kiro agent sources: the Kiro projectors now bound the field set they emit rather than passing unmapped source frontmatter through verbatim. Claude Code fields Kiro cannot read (permissionMode, memory, maxTurns, …) and IDE-only keys that make the CLI loader drop an agent (hooks) are dropped, each with a kiro: dropping … agent field line on stderr. If you relied on the previous pass-through, check your build log after upgrading.

What's new in 0.39.3

The bundled workspace-status engine now recognizes reviewed legacy work-intake migrations, validates durable operation digests, and refuses linked or aliased workspace input before projecting exact legacy bytes.

What's new in 0.39.2

Level A packs can now provide an optional manual next step after installation. When present, agentbundle install prints it after Verify:, so packs can guide adopters even when a runtime hook does not execute. Existing packs without the field keep their current output, and Level B packs still require it.

What's new in 0.39.1

Catalogue seed lint now rejects generic directory-tree placeholders unless the architecture overview also explains each area's responsibility and change guidance. This keeps generated starter repositories useful without assuming a particular application layout.

What's new in 0.39.0

Catalogue builders can now inspect a first-class, schema-validated distribution route contract for the existing APM and Claude-plugin package formats. Recipes name their route explicitly and fail before writing on inconsistent route data; the emitted package trees and direct-install behavior are unchanged.

What's new in 0.38.6

Catalogue authors can now read the profile schema from initialized catalogues with agentbundle catalogue contracts show profile.schema.json. The bundled profile-authoring instructions no longer direct them to a repository-only path.

What's new in 0.38.5

The bundled authoring scaffold now says how to write pack tests that survive a shared interpreter: load a skill's modules under a unique name rather than putting its scripts/ directory on sys.path, and keep a suite's cost in assertions rather than in spawned processes. Separately, a repository-only conformance test no longer travels into catalogues created with --preset self-hosted; the shipped conformance set is derived in one place, so the manifest plain init reads and the directory self-hosted init copies can no longer disagree.

What's new in 0.38.4

The bundled catalogue authoring scaffold's packs/AGENTS.md and profiles/AGENTS.md state rules that an earlier simplification had dropped: path canonicalisation before a read, treating a user-controlled local file as data rather than instructions, confirming a shared user-level config path belongs to the current project, UTF-8 output streams for scripts that print, eval-harness coupling, and the two profile invariants — a pack appears at most once, and packs declaring a conflict do not share a profile. Catalogues created with agentbundle catalogue init start with these; no CLI verb, flag, or output format changed.

What's new in 0.38.3

The workspace_status MCP result now reports safe tracker-refresh availability facts: origin mode, active profile, compared and accepted revisions, unresolved conflict state, and explicit or unknown refresh and write-back availability. The response still withholds field ownership, decisions, receipts, and approver identities, so no CLI verb, flag, or output format changed for existing callers.

What's new in 0.38.2

The bundled catalogue authoring scaffold now has shorter, restructured packs/AGENTS.md and profiles/AGENTS.md files. Catalogues created with agentbundle catalogue init start with leaner instructions; no CLI verb, flag, or output format changed.

JOURNEY.md can now optionally list ordered contract.decisionGateIds drawn from humanGates[].id. Gate labels still provide reader-facing wording, and yourDecisions remains required, so existing packs stay valid without changes. This engine change shipped after 0.38.1 and reaches PyPI for the first time here.

What's new in 0.38.1

agentbundle catalogue self-host --check --windows gained a stage that verifies a source catalogue's declared knowledge bundles against their committed output. The verification itself is performed by the catalogue's own tooling, so this changes nothing for installing or using a pack.

What's new in 0.38.0

agentbundle show <pack> --format json now emits the additive pre-release rich discovery fields pack_metadata, skill_metadata, and knowledge when the pack is read from a live catalogue. The existing fields keep their current meaning and ordering; installed-state fallback cannot prove rich metadata, so those three fields are exactly null there.

The rich discovery surface is deliberately one-pack-at-a-time. It does not add OKF data to list-packs, Claude marketplace output, catalogue-index.json, or installed state, and it does not run compilers, network fetches, or pack code.

Catalogue verification

agentbundle catalogue verify performs all 19 advertised checks. It validates profile schemas and pack references, dependency ranges and cycles, adapter compatibility, generated-output drift, pack preflight metadata, and skill evaluation manifests. The verifier remains read-only and portable across external catalogues.

Dependency ranges use the same npm-compatible grammar in verify, lint, and install: caret, tilde, comparator, compound, and prerelease forms agree across all three commands. In particular, caret ranges below 1.0.0 use normal semver compatibility (^0.2 does not include 0.3.x).

agentbundle catalogue index now generates a deterministic, adapter-neutral catalogue-index.json from catalogue, pack, profile, and optional journey metadata. The command validates against its bundled public schema before an atomic no-follow write; --dry-run writes nothing, and --format json emits one closed result document for automation.

The generated index exposes content-addressable pack digests, structural content and execution inventory, profile composition, declared external effects, and forward and inverse pack integrations without relying on one agent host's marketplace format.

Catalogue authoring

New catalogue scaffolds document the JOURNEY.md convention: required and optional frontmatter, external-effect declarations, reader-facing body sections, and migration guidance. Existing packs without a journey remain valid and appear with an empty journeys array.

The same authoring reference retains the guide callout contract: exact quoted wording remains a blockquote, while guidance uses the documented typed aside.

Generate and validate a neutral index with:

agentbundle catalogue index . --dry-run
agentbundle catalogue index . --output catalogue-index.json

Contract discovery

The bundled public contract inventory includes distribution-routes.toml and its closed schema for package-route semantics, plus catalogue-index.schema.json for generated neutral indexes. It also includes the strict knowledge-captured-observation.schema.json contract used by the core pack's project-knowledge capture handoff.

You can inspect the exact public contracts bundled with the installed AgentBundle version without network access:

agentbundle catalogue contracts list
agentbundle catalogue contracts show pack.schema.json
agentbundle catalogue contracts export --output ./reference-contracts

list and show are read-only. export writes reference copies through a no-follow, preflighted batch writer; those copies do not override the contracts AgentBundle uses for validation.

Successful agentbundle catalogue init output points to the scaffolded guides/_shared/reference/catalogue-authoring-standards.md, contract discovery, and catalogue verification. JSON init output remains unchanged.

Install into a repo — so everyone who clones it gets the pack. core is the flagship pack, the loop itself:

agentbundle install --pack core

No catalogue argument needed: it defaults to the agent-ready-repo catalogue. It lands in the repo's agent config — subagents and skills included — and you commit it like any other project file. This is the default scope: the pack belongs to the project and the whole team.

Install for yourself, everywhere — so a pack follows you across every project, with no per-repo setup:

agentbundle install --pack desk-research --scope user

User-scope packs land in your home directory, not the repo — they're yours, not the team's, and they're there in every project you open.

Try a pack without committing it — so the pack is live in this clone while git status stays clean:

agentbundle install --pack core --scope local

Local scope projects the same runtime files as repo scope, then records them in .git/info/exclude. It requires a Git work tree. Uninstalling removes both the projected files and the managed exclude entries; local and repo installs of the same pack cannot coexist.

The install auto-detects your agent (--adapter overrides). Multi-IDE? Install the same pack for each agent at the same scope — they coexist, and the agents that read .agents/skills/ (codex, cursor, gemini, copilot) share one skill copy instead of fighting over it. To install from a different catalogue, pass it as a trailing argument — a git URL or a local path (agentbundle install --pack core <catalogue>); a config set source <catalogue> makes that the default, and an editable clone (pip install -e) defaults to itself.

Claude Code marketplace

Claude Code users can install any pack that permits user scope without first installing this CLI:

claude plugin marketplace add eugenelim/agent-ready-repo
claude plugin install architect@agent-ready-repo

The marketplace excludes repo-only packs because Claude plugins live in a global cache. Install core and other repo-only packs with agentbundle so their files land in the project. For hook-bearing user-scope packs, the generated marketplace description lists the authored hook event, matcher, timeout, interpreter, and body path before publication.

# Uninstall — previews remove (Tier-1) vs keep (your edits), asks first
agentbundle uninstall --pack core --dry-run
agentbundle uninstall --pack core --yes

list-installed reads your state files (not the catalogue) and reports every installed (pack, adapter) at each scope with its version and a four-value status — up-to-date, upgrade-available, ahead (installed version is newer than catalogue), or unknown; it degrades to unknown (never an error) when the catalogue can't be resolved, and --no-check skips the check entirely. --format json emits a stable JSON contract (schema_version: 1) to stdout — useful for CI automation of upgrade decisions. --updates-only hides up-to-date rows.

show <pack> answers "what skills and agents does this pack contain?" by walking the pack's source tree live on each call — so the answer can't drift, and nothing is persisted. --format json emits a stable object (name, version, description, skills, agents, integrations, source, pack_metadata, skill_metadata, knowledge) for scripts and agents. The three rich metadata fields are pre-release: they are source-backed only for live catalogue reads and are not a cross-pack OKF index. When the catalogue can't be resolved, an installed pack still reports its inventory from your state files (marked source: installed-state), with pack_metadata, skill_metadata, and knowledge set to null; a not-installed pack errors.

A profile is a catalogue-curated, single-scope set of packs you install in one command — it declares its own scope, so --scope doesn't apply. Upgrade takes no version — the target is whatever the catalogue you point at declares; to pin a past version, point the catalogue at that git ref. Install a pack that's already there and agentbundle offers to upgrade it instead (--yes runs it straight away).

Mutating commands ask first. uninstall, the --force cleanup, and the upgrade offer all preview what they'll do and confirm before touching anything; --dry-run previews without writing, and --yes skips the prompt for non-interactive / CI use (where, without it, they refuse rather than hang).

Enterprise distribution

For organizations running an internal Artifactory mirror or any static HTTPS server, agentbundle's enterprise distribution capabilities handle the full adoption loop — from org-wide channel configuration to CI-driven bulk upgrades.

Install from an internal Artifactory channel:

# Point agentbundle at your org's channel descriptor (one-time per machine,
# or pre-configured in your org fork — see Org bootstrap below)
agentbundle config set source catalogue+https://artifactory.example.test/agentbundle/catalogues/core/channels/stable.json

agentbundle install --pack core

The channel descriptor points to an immutable versioned archive; agentbundle fetches, verifies its SHA-256 digest, and installs. Pass a bearer token via AGENTBUNDLE_HTTP_BEARER_TOKEN — it is never stored in state, never printed, and never forwarded to a different host.

JSON output for CI pipelines:

# See what's installed and what needs upgrading — machine-readable
agentbundle list-installed --format json
agentbundle list-installed --format json --updates-only

Returns a stable JSON contract (schema_version 1) with per-row status (up-to-date / upgrade-available / ahead / unknown) and machine-readable reason codes for unknown rows. Pipe into jq or your CI annotation step.

Bulk upgrade in one scoped command:

# Upgrade all installed packs in a scope — preflights before any write
agentbundle upgrade --all --scope repo --yes
agentbundle upgrade --all --scope user --format json --yes

Preflights all rows before writing anything; a blocked row stops the run before the filesystem is touched. Partial failure is reported honestly — not described as a rollback. Never silently downgrades an ahead row.

Package your catalogue for Artifactory:

agentbundle catalogue package \
  --root /path/to/catalogue \
  --bundle my-packs \
  --release 1.0.0 \
  --channel stable \
  --output dist/

Produces a deterministic, reproducible gzip archive (versioned) and a mutable channel descriptor JSON (stable.json), ready to upload to Artifactory. Identical inputs produce byte-identical archives (honors SOURCE_DATE_EPOCH).

Build residue is excluded, so it does not matter whether you packaged a working tree you had just tested or npm-installed in. Pruned at every level of a pack: __pycache__, .pytest_cache, .mypy_cache, .ruff_cache, .tox, .hypothesis, htmlcov, node_modules, .venv, venv — plus *.pyc, *.pyo, .DS_Store, coverage.xml and .coverage* shards. The drop is silent, so do not name a directory you mean to ship after one of those.

Source distribution for air-gapped or self-hosted catalogues:

agentbundle catalogue package \
  --root /path/to/catalogue \
  --bundle my-packs \
  --release 1.0.0 \
  --flavor source \
  --output dist/

Produces a catalogue-source-<release>.tar.gz from a positive allowlist (catalogue.toml, packs, profiles, guides, a marketplace manifest when present, and legal files), with the same build-residue exclusions as the default flavour. Includes a self-hosted-source-manifest.json with per-file SHA-256 digests and provenance fields. agentbundle install refuses to install a source archive, preventing accidental misuse.

Org bootstrap — ship the default channel in your fork:

Add an [organization.artifactory] block to agentbundle/_data/install-defaults.toml in your org's agentbundle fork:

[organization.artifactory]
enabled = true
base-url = "https://artifactory.example.test"
repository = "agentbundle"
bundle = "core"
channel = "stable"

Developers installing from your fork get the internal channel without a manual config set source step. The block ships enabled = false in the public package. A malformed enabled = true config fails closed — no silent fallback to the public source.

Offline and air-gapped hosts: set AGENTBUNDLE_NO_REMOTE=1 to skip the org Artifactory bootstrap and editable-install detection entirely. agentbundle falls straight through to the packaged default, so hosts without network access to Artifactory still resolve a source without errors.

See Configure catalogue enterprise distribution for channel setup, authentication, CI upgrades, disconnected hosts, and the security boundary.

Build your own catalogue

agentbundle isn't tied to the agent-ready-repo catalogue. A catalogue source has two required root markers: a valid catalogue.toml and a literal packs/ directory. A custom catalogue.paths.packs value controls where pack content is read from; it does not replace the root packs/ marker.

Bootstrap a new catalogue in an empty directory:

agentbundle catalogue init --target /path/to/new-catalogue

Scaffolds catalogue.toml, the required directory tree (packs/, profiles/, contracts/, .claude-plugin/), and a starter marketplace.json. Skips files that already exist; reports conflicts without overwriting. Pass --dry-run to preview.

After initialization, use agentbundle catalogue contracts list to find the contract names bundled with your installed version. show prints one contract; export --output <dir> copies the full public set for offline reference.

Bootstrap a self-hosted enterprise catalogue from an existing source:

agentbundle catalogue init \
  --preset self-hosted \
  --source /path/to/source-catalogue.tar.gz \
  --tooling vendored \
  --attribution white-label \
  --repository-url https://github.com/your-org/your-catalogue \
  --owner-email admin@example.com

Copies selected packs and profiles from the source archive, generates catalogue.toml with your identity, runs a fail-closed leak check, and writes .agentbundle/self-host-state.json to track managed files. --tooling vendored also copies the agentbundle source and catalogue-curation pack into .agentbundle/tooling/ for air-gapped deployments. Re-run to apply updates; stale owned files are removed (sha256-guarded, user-modified files are skipped).

A pack is a directory:

my-pack/
  pack.toml                  # name, version, adapter-contract, install scope,
                             # plus rich metadata (license, maintainers, links,
                             # categories, keywords) and a README pointer
  .claude-plugin/
    plugin.json              # Claude Code plugin manifest (hand-authored)
  README.md                  # the pack's portable doc — projected with the pack
  .apm/                      # runtime — projected by the build pipeline
    skills/<name>/
      SKILL.md               # the skill body; one folder per skill
      scripts/               # helper code the skill invokes
      references/            # progressive-disclosure docs, loaded on demand
      assets/                # templates the skill copies into the repo
      evals/                 # activation + output-quality evals, skill-local
    agents/<name>.md         # subagents
    hooks/<name>.py          # lifecycle hooks
    hook-wiring/<name>.toml  # adapter event wiring for a shipped hook body
  tests/                     # implementation tests — NEVER projected
    skills/<name>/
    hooks/
    pack/
  seeds/                     # files scaffolded into the adopter repo

Three boundaries: the pack owns and executes its tests, .apm/ is the runtime export boundary, and a skill owns its eval fixtures. Only .apm/ and seeds/ are projected into an installed environment — tests/ is visible in a catalogue archive, so an extracted pack can verify itself, but install never places it. Keep tests out of .apm/ even though the installer would ignore them there; the separation is structural, not incidental.

pack.toml is the single source of truth for a pack's metadata. Declare license, [[pack.maintainers]], [pack.links], categories, and keywords once; the build projects the cleanly-mappable subset — plus the pack's README.md — into each distribution route's manifest (the plugin.json / marketplace.json entry), so the catalogue describes each pack richly rather than with a single sentence. The Claude-plugin route carries only packs whose [pack.install] allowed-scopes admits user: a plugin's code lands in the adopter's global cache, so a repo-only pack gets no marketplace.json entry and is reached with agentbundle install instead. A marketplace entry's source is a git-subdir object (url, path, and one of ref/sha) pointing at the pack's directory on the published distribution branch, and every entry is schema-validated at build time against marketplace-entry.schema.json. Extra fields stay in pack.toml; the projection is deliberately lossy per tool.

A hook-bearing pack that permits user scope must explicitly set [pack.install] user-scope-hooks = true. On the Claude-plugin route, agentbundle compiles supported Claude-shaped wiring into native plugin hooks and rejects unsafe event, matcher, timeout, command, or body-path shapes before creating output. Direct CLI installs keep their adapter-native wiring contract.

Point a catalogue URI (a git URL or a local path) at the repo that holds your packs. Then validate a pack against the adapter contract, render it to preview the projection, and install it into a target repo. scaffold drops a pack's seeds into a fresh directory to start from. The build pipeline (agentbundle.build) is the same engine make build runs.

Org adapter default: If your org ships a private agentbundle wheel (or a fork pinned to your internal catalogue), you can set a default adapter for all developers without requiring them to run agentbundle config set or pass --adapter on every install. Add an [organization] table to _data/install-defaults.toml in your fork:

[organization]
preferred_adapter = "cursor"

The org hint fires after the user-config but before the on-disk IDE probe — so --adapter, user-config, and upgrade state-hints all take priority. An invalid value exits 1 before writing anything. See the agentbundle reference for the full cascade.

Bundled contracts — the wheel ships the machine contracts used for offline validation: pack.schema.json, skill.schema.json, guide.schema.json, skill-manifest.schema.json, profile.schema.json, catalogue.schema.json, plugin-manifest.schema.json, plugin-manifest.derived.schema.json, marketplace-entry.schema.json, target-vocab.toml, and the adapter contract files. All are available without network access via importlib.resources.

Lint your catalogue — shallow structural checks run without extra dependencies:

agentbundle catalogue lint --root .

Lint validates both source markers and then checks the configured pack content. It requires .claude-plugin/marketplace.json only when the effective self-host adapters include claude-code. A Kiro-only catalogue can omit that Claude artifact; the default Claude Code and Codex projection still requires it.

For full agentskills.io spec compliance (frontmatter key set, description policy, encoding, evals schema), install the lint extra and run with --deep:

pip install 'agentbundle[lint]'
agentbundle catalogue lint --root . --deep

Verify a catalogue before you ship it — runs the full read-only contract and self-host checks in one command:

agentbundle catalogue verify --root .

For a self-host-enabled catalogue with .adapt-discovery.toml, that includes the self-host classifier. It treats generated targets as projected and known repository-owned paths as excluded from projection. A genuinely unknown Git-visible path remains an informational unclassified notice; it does not fail an otherwise clean catalogue. Missing, modified, or orphaned projections do fail verification, including generated executables under .agentbundle/bin/ and vendored user libraries under .agentbundle/lib/. Git filenames are read losslessly, and a failed Git listing is reported as a warning rather than mistaken for a fully classified inventory.

To check only self-host projection drift, or to regenerate projected files locally:

agentbundle catalogue self-host --check --root .
agentbundle catalogue self-host --write --root .

Both check commands are safe to run in CI. The write command changes projected files.

By default projects for claude-code and codex. Downstream repos that use a single adapter (e.g. kiro-ide) can declare it in catalogue.toml — only that adapter is then projected, and its output files participate in the drift check:

[distribution.agentbundle]
preferred-adapter = "kiro-ide"

When preferred-adapter names an adapter not in the upstream SELF_HOST_ADAPTERS list, the self-host engine switches to single-adapter mode: only the named adapter is projected; Claude Code-specific artifacts (.claude/, .codex/, .claude-plugin/, CLAUDE.md) are neither written nor drift-checked.

Run Tier-A activation evals to measure whether each covered skill fires on the prompts it should:

agentbundle pack evals run --pack <pack-name> --catalogue-root .

See the pack layout reference and authoring a skill.

Catalogue defaults and pack config API

Catalogue defaults let operators ship sensible starting values for every pack they distribute. Add a [pack-defaults.<pack-name>] table to catalogue.toml and the defaults are baked in at publish time. They slot into the three-layer cascade: pack-source defaults → operator defaults → user config. A custom install root is also supported via [catalogue] user-dir = "~/custom/path".

Pack scripts can resolve their user-scope directory and read the merged config at runtime using the agentbundle.config API:

from agentbundle.config import pack_dir, load_pack_config

directory = pack_dir("my-pack")                 # ~/.agentbundle/my-pack/
config = load_pack_config("my-pack")            # merged dict: pack defaults + operator + user

Operation log — scripts can append structured JSONL records to <pack_dir>/ops.jsonl for lightweight audit trails:

from agentbundle.oplog import write_entry

write_entry("my-pack", "install", src="git+https://example.com/my-pack")

CLI commands to read, write, and inspect pack config and operation logs:

agentbundle pack-config show my-pack            # all config values for a pack
agentbundle pack-config get  my-pack api-key    # single value
agentbundle pack-config set  my-pack api-key v  # write to user config.toml

agentbundle oplog show  my-pack                 # JSONL operation history
agentbundle oplog clear my-pack                 # wipe history (asks first)

Per-session MCP server (workspace-mcp)

The core pack ships a per-session MCP server that a control harness can inject into each Claude Code session. It exposes six tools over MCP stdio:

Spawn it (the harness does this, not the agent):

python3 -m agentbundle.workspace_mcp

Trusted checkout only. This form runs whichever agentbundle is on sys.path. If the repo uses an editable install (pip install -e .), it runs the local checkout's code. Use only on repos you trust. An isolated spawn mode (python3 -I -m agentbundle.workspace_mcp) is planned for Stage 2 and will require a stable non-editable install.

In trusted mode, workspace status prefers an installed core-pack projection and falls back to the byte-identical engine projection bundled with agentbundle.

Inject the session instruction so the agent knows to use the tools:

from agentbundle.workspace_mcp import DEFAULT_SESSION_INSTRUCTION

Pass exactly one environment variable when spawning to set the session mode: WORKSPACE_MCP_SPEC_PATH (path to the spec directory) for FSM/work-loop items, or WORKSPACE_MCP_DISPATCHED_ITEM (ini_slug/type:slug) for non-FSM shaping items. Setting neither gives discovery-only mode (git writes disabled). Setting both is unsupported — only one selects the mode.

macOS is the only platform where Python ignores the operating system's trust store, which is why the automatic fallback above is macOS-only:

If your IT team gives you a CA bundle, point AgentBundle at it directly:

export AGENTBUNDLE_CA_BUNDLE=/path/to/corporate-ca.pem
agentbundle install --pack core

On git+https:// sources that bundle is added to the default trust store, so a bundle holding only your private authority still verifies public hosts. On catalogue+https:// and archive+https:// it replaces the store, pinning verification to your own authority — useful for an internal Artifactory mirror.

WSL is the case most likely to catch out a Windows-standardised organisation: your IT team pushes the authority to Windows, Windows tools pick it up, and nothing inside the WSL distribution does. Export it from Windows (Certificate Manager → Trusted Root Certification Authorities → Export as Base-64 X.509), then install it in the distribution:

sudo cp corporate-ca.crt /usr/local/share/ca-certificates/
sudo update-ca-certificates

Two things no certificate configuration can fix: a proxy that requires Kerberos or NTLM authentication, and an egress allowlist that permits github.com but not codeload.github.com — a GitHub archive fetch redirects across both hosts.

A note on virtualenvs, since it comes up: creating one does not change TLS trust. A virtualenv inherits its base interpreter's certificate store unchanged. If an install works under one python3 and not another, the interpreters differ, not the environment — compare them with python3 -c "import ssl; print(ssl.get_default_verify_paths())".

Credentials

agentbundle doesn't resolve secrets. Credentialed skills use credbroker, a standalone resolver that keeps cleartext out of the model's reach.
