Update Aegis

Update Aegis

Update the installed Aegis Method Pack for the current AI coding host.

This skill is host maintenance. Do not edit the target project just because the user asked to update Aegis.

Default Semantics

• aegis:update updates the current host's registered Aegis installation.
• Updating every registered host requires an explicit --all request.
• If more than one host is registered and the current host cannot be identified, ask one concrete question before updating.
• Do not update a development checkout when the installed method-pack root is a separate path.
• Do not perform background automatic updates. The local registry may record updateMode, but this skill only performs explicit user-triggered updates.

Evidence First

From the installed method-pack root, inspect the host-scoped registry:

python scripts/aegis-update.py status --json

If the registry is missing, register the current host before updating. Use the host's install guide and actual discovery path rather than guessing.

If ~/.config/aegis/config.toml already declares method_pack_root, prefer that canonical root when registering additional hosts. Host-specific discovery paths, copied skill directories, plugin caches, or adapter payloads should be treated as generated / host-managed views into the same Aegis body, not as separate editable checkouts.

Codex example:

python scripts/aegis-update.py register \
  --host codex \
  --sync-mode junction \
  --discovery-root ~/.agents/skills/aegis \
  --reload-hint "restart Codex"

Copy-based host example:

python scripts/aegis-update.py register \
  --host codebuddy \
  --sync-mode copy-skills \
  --discovery-root ~/.codebuddy/skills \
  --reload-hint "restart CodeBuddy"

Plugin-managed hosts can be registered, but the updater reports that the host plugin manager owns the update path:

python scripts/aegis-update.py register \
  --host opencode \
  --sync-mode plugin-managed \
  --reload-hint "restart OpenCode"

Update Commands

Current or explicitly selected host:

python scripts/aegis-update.py update --host <host> --json

All registered hosts, only when the user explicitly asks for all-host update:

python scripts/aegis-update.py update --all --json

Preview without touching files:

python scripts/aegis-update.py update --host <host> --dry-run --json

If the installed checkout has local changes, do not overwrite them. Either ask the user how to proceed or, with explicit permission, preserve them with:

python scripts/aegis-update.py update --host <host> --stash --json

Completion Evidence

Treat the update as complete only when the updater reports the selected host and the post-update doctor verification succeeds. For link-based discovery roots (junction, symlink, or repo-only), the updater passes discoveryRoot through to aegis-doctor.py --discovery-root. For copy-based hosts, it verifies that copied Aegis skill directories exist after the copy step, then runs doctor against the method-pack root.

When multiple registered hosts share the same methodPackRoot, the updater now reuses a single method-pack checkout update and then refreshes each host's exposure or verification path separately.

Report:

• selected host / installation id
• previous and final commit when available
• whether the install was updated or already current
• sync mode used
• doctor verification result
• restart or reload hint

If the updater skips a plugin-managed host, state that the host plugin manager owns the update path and give the reload or reinstall hint.
