Skill Sync had no default base URL, so a user with no `sync.base_url` in
config.yaml and no HERMES_SYNC_BASE_URL got:
sync inert: no sync base URL configured (config.yaml sync.base_url
or HERMES_SYNC_BASE_URL).
Every sync command was unusable out of the box. The URL was left unset
because the plane did not exist yet when the client was written; it does now.
- Adds DEFAULT_SYNC_BASE_URL = "https://gateway-gateway.nousresearch.com" and
returns it as the last step of resolve_sync_base_url().
- Resolution order is unchanged otherwise: HERMES_SYNC_BASE_URL ->
config.yaml sync.base_url -> production default. The env var and config key
now exist to point a dev/staging build at another plane rather than to make
the feature work at all.
- Follows the existing precedent for production endpoints in this codebase
(DEFAULT_NOUS_PORTAL_URL in hermes_cli/auth.py, HERMES_DIAGNOSTICS_BASE_URL
in diagnostics_upload.py): a module constant with env/config override.
The "no sync base URL configured" guards are kept — they are now unreachable
in practice but remain correct if the default is ever blanked.
Tests: 3 new — the default is returned when nothing is configured, config
still overrides it, and the constant is a bare https origin (no trailing
slash, no path) since the client appends /v1/sync/. 2349 passed / 0 failed
across 56 suites via scripts/run_tests.sh.
Verified against a temp HERMES_HOME with no config: resolves to the
production plane; HERMES_SYNC_BASE_URL and sync.base_url both still win, and
trailing slashes are stripped.

Skill Sync client -- the low-level sync layer.
|
|
|
|
This is the LOW-LEVEL sync layer. It builds content-addressed objects
|
|
(blob/tree/commit) from local skills, talks the sync wire contract to a sync
|
|
plane (push objects + CAS a ref, pull the owner's HEAD, three-way merge on a
|
|
409), and is driven by:
|
|
|
|
* a debounced push hook in ``skill_manage`` (after the write-gate passes),
|
|
* a periodic pull hook (``maybe_pull_skills``) at the curator tick sites,
|
|
* the ``hermes sync status|pull|push|now`` CLI.
|
|
|
|
It lives beside ``tools/skills_sync.py`` (NOT under ``hermes_cli/``) so the
|
|
low-level sync layer never imports the CLI -- same rule the bundled-skills
|
|
sync module documents at ``skills_sync.py:43-50``.
|
|
|
|
Contract: the Skill Sync wire contract (version 1, frozen
|
|
for Milestone 1). Endpoint shapes, object model, canonicalization, and status
|
|
codes below all trace to that document.
|
|
|
|
--- ACCESS GATE (pre-launch) ---------------------------------------------
|
|
Client sync is INERT (no push, no pull, no-op) unless the signed-in user is a
|
|
**Nous admin**. We read that off the access token, which rides on the same
|
|
bearer ``resolve_nous_runtime_credentials()`` returns; we decode the JWT
|
|
payload (no signature verification -- the server re-verifies) and check the
|
|
claim before doing any sync work.
|
|
|
|
NAMING: the claim on the wire is ``tool_gateway_admin``, which is misleading
|
|
-- it is NOT a tool-gateway-specific right. NAS populates it from
|
|
``Permissions.ADMIN_ACCESS`` (access-token-issuer.ts), the same global portal
|
|
admin permission that guards ``/admin/*``; the claim is simply named for its
|
|
first consumer. We keep the wire name (other services read it) but call it
|
|
what it means everywhere on this side.
|
|
|
|
This gate is pre-launch containment, not the shipping entitlement. Admin
|
|
status conflates "may administer Nous" with "has Skill Sync enabled", and has
|
|
no middle setting for a beta cohort -- opening it up would mean handing out
|
|
portal admin. Replace it with a real entitlement (a ``sync:*`` scope, a tier
|
|
check, or a per-cohort feature flag) before shipping to users.
|
|
|
|
--- OPT-IN DEFAULT (M1-D, provisional) -----------------------------------
|
|
Nothing syncs unless the user marks a skill for sync. The user's local intent
|
|
is toggled via ``hermes sync enable/disable`` (a ``sync`` flag on the skill's
|
|
``.usage.json`` sidecar, alongside ``pinned``/``created_by``), but the DURABLE,
|
|
CROSS-DEVICE opt-in state is a committed ``sync-manifest`` object in the sync
|
|
plane (design.md §2.8): a root-level blob in the tree at
|
|
``refs/user/<owner>/HEAD`` recording per-skill ``{name, enabled}``. Push writes
|
|
the manifest from local intent; pull reconciles local intent FROM it, so a skill
|
|
opted in on one device becomes opted in on the others. The plane manifest is
|
|
authoritative; the local flag is just the editable intent. Only agent-created +
|
|
user-authored skills under ``~/.hermes/skills/`` are eligible; bundled and
|
|
hub-installed skills are excluded.
