The Privacy Model (one ladder)
Every asset has exactly one privacy tier — each is strictly more open than the last:
privacy
Who can open the link
only_me
The owner only (plus anyone given an explicit share link)
workspace(default)
Owner + workspace members — a teammate opening the link verifies their work email once, then sees everything their team has shared
public
Anyone with the URL
Three more facts complete the model:
status is a separate axis: published (default; discoverable in the workspace gallery) vs unpublished (hidden, but still viewable via preview/workspace links). Status never affects the privacy tier.
"Externally shared" is not a tier. Share links (emails/domains + verification) work on any non-public asset; the API reports the derived externallyShared: true on an asset that has at least one share link. Creating or revoking shares never changes privacy.
Locked-out viewers can knock. A code-verified visitor who hits an asset they can't open (workspace or share flow) can request access; those requests land in the owner's inbox (see Access Requests workflow).
Link lifetimes: share links never expire by default (expiry is opt-in per share); a viewer's verified session and a previewUrl each last ~30 days. Rule of thumb: hand out a previewUrl for a teammate's quick look, a share link for an external "review this deck" — neither will rot mid-conversation. Revoking a share still cuts access immediately.
Usage
/octave:asset-manager # Interactive - asks what to do
/octave:asset-manager publish <path> # Publish a folder, file, or .zip
/octave:asset-manager update <identifier> # Replace files or change metadata
/octave:asset-manager share <identifier> # Create/manage share links
/octave:asset-manager versions <identifier> # Version history, rollback, pinned URLs
/octave:asset-manager requests # Access-request inbox (grant / dismiss)
/octave:asset-manager stats <identifier> # Visits, downloads, who opened it
/octave:asset-manager list # List published assets (from registry)
/octave:asset-manager download <identifier> # Download an asset's files locally
/octave:asset-manager delete <identifier> # Delete an asset (confirms first)
The One Decision Rule
Every operation routes through exactly one of two backends. Never mix them up:
Operation
Route
Upload new files, replace files, download files (current or a pinned --version)
Bash scripts in ${CLAUDE_PLUGIN_ROOT:-.}/skills/asset-manager/scripts/
Never use update-artifact.sh for metadata-only changes — that is asset_update's job.
Never try to upload files via MCP — no such tool exists (intentionally).
MCP Tools Are Tool Calls (never bash)
assets_list, asset_generate_access_token, asset_update, and every other asset_* tool are tool calls. You cannot reach them through bash or python.
Never write a script that echoes, simulates, curls, or "assumes" the result of an MCP tool. A check whose tool result is not in your transcript did not happen.
Never print "assuming no duplicates found" or "ready to proceed once token is available" — each of those is the signal that the next action is the missing tool call itself, right now.
The script headers mention POST /api/v1/user/access-token — that endpoint is for service operators with a service key. You cannot call it. Your ONLY token source is the asset_generate_access_token / asset_refresh_access_token tool calls.
No helper scripts. The 4 bundled scripts are the only shell this skill needs; the single permitted extra shell is the one-line staging cp/rm documented where it's used. Do not write wrappers, staging helpers, or scripts that print status instead of performing an action.
Check Before Create (Cache Rule)
The asset store doubles as a cache: the asset the user wants may already exist — created by you in another project or session, or by a workspace teammate (workspace-shared assets appear in assets_list with their owner). Never create a new asset without checking first.
Before ANY new upload:
Run a fresh assets_list. Never trust the local registry alone for this — it is per-project and lags behind assets created elsewhere.
Match the intended asset against existing ones: normalize identifiers (kebab-case → words) and compare against the intended name/topic keywords; scan descriptions; weigh type (website vs storage).
Plausible matches found → AskUserQuestion with up to 3 candidates. Each option shows the identifier, and its description says what it is, who owns it (owner: "me" or a teammate's name), plus the link (siteUrl, previewUrl for non-public, or download URL). Always include a final option: No — this is new, create it. A teammate-owned match can be reused and downloaded, but never modified — to change one, create the user's own copy.
User picks a match → show its link, then ask what next: nothing / update its files / change metadata / manage shares.
User says it's new → proceed to publish, choosing an identifier distinct from the matches (avoids a 409).
No match → proceed directly, mentioning that nothing similar was found.
Ordering constraint: assets_list is an MCP asset call and rotates the access token — always do this check BEFORE minting the upload token.
Workspace Sharing & Preview Links
Assets default to the workspace tier: teammates can READ them through the API (list/get/download) — even unpublished ones — and can open the live /sites link itself by verifying their work email once. All mutations and share management stay owner-only. Set privacy: only_me at create (or later) to keep an asset owner-only.
Every asset response carries owner: "me" for your own, otherwise the teammate's "First Last <email>". Teammate-owned assets are read-only — never call asset_update, asset_delete, or any share tool on them; if the user wants changes, create their own copy.
Every asset response also carries externallyShared (derived): true when a non-public asset has at least one share link — a quick "who else can see this" signal.
Non-public assets (only_me, workspace, or unpublished) carry a previewUrl: a tokenized link that renders the site/download for the owner and workspace members without making it public. It is null once the asset is published + public (use siteUrl then). It lasts ~30 days but is minted per read — NEVER store it in the registry; fetch a fresh one with asset_get_by_id when someone needs it.
Always include the link. Every time you list, upload, update, or otherwise mention an asset, include its link:
published + public → Public — anyone with the link can view: <siteUrl> (websites) or <base>/download/<uuid> (storage)
workspace tier → the siteUrl works for teammates directly (they verify their work email once); include the previewUrl too for a zero-friction open.
only_me or unpublished → Preview (you + workspace members): <previewUrl> — taken fresh from the response in hand (list/get) or the script's preview: output line, never from the registry. Add a share link for people outside the workspace when relevant.
MCP Server Detection
Refer to tools by bare name (asset_update, assets_list, ...). The live server is named mcp__octave-<workspace>__* — the workspace suffix varies per user. Detect the active Octave MCP server from the available tool list; never hardcode a prefix.
The access token authorizes the bash scripts. Its lifecycle has one hard rule:
Every MCP asset call rotates the token. Any asset_* / assets_list call internally mints a fresh token for this user+workspace and invalidates the previous one. A token you got a minute ago is dead the moment any other asset MCP tool runs.
Therefore:
Mint the token via asset_generate_access_tokenimmediately before each batch of bash script calls — after all MCP calls for this step are done.
If any asset MCP call happens mid-flow, re-mint before the next script call.
If a script returns 401: call asset_refresh_access_token, retry the script once.
STOP precondition: before running ANY script you must hold an accessToken value returned by a tool call in this conversation. If you don't have one, the next action is the asset_generate_access_token tool call — not a script, not a question to the user.
Script invocation form (inline env only — never export into the profile, never echo the token, never write it to any file):
(The scripts resolve the base URL themselves — see Base URL Resolution. Prefix ARTIFACTS_URL='<url>' only when the user explicitly targets a different environment.)
In the registry, record only the token prefix and expiresAt — never the plaintext token.
Base URL Resolution
The scripts resolve the base URL themselves — do not compute or pass it unless the user explicitly targets a different environment. Resolution order (built into every script):
ARTIFACTS_URL environment variable (explicit override — set it only when the user asks for a specific environment)
.env at the plugin root (development clones only — never present in marketplace installs)
Production default: https://link.octavehq.com
Record the base URL the API reports back (e.g. from siteUrl) as base_url in the registry — it's a record of where the assets live, not an input.
The Bundled Scripts
All in ${CLAUDE_PLUGIN_ROOT:-.}/skills/asset-manager/scripts/ (bash + curl; jq optional; works on macOS/Linux/Windows via Git Bash or WSL):
Script
Purpose
Key flags
zip-and-upload-artifact.sh
Zip a folder locally, upload as one request (default for folders; zip fallback chain: zip → powershell → python)
Upload a ready .zip, or a folder as per-file multipart (fallback if zipping fails; skips dotfiles)
same as above, --src accepts folder or .zip
update-artifact.sh
Replace an asset's files (FULL REPLACE — mints a new immutable version)
--uuid <u> --src <path> --note <text> (--note = "what changed" on the minted version; only valid with --src)
download-artifact.sh
Download all files of an owned or workspace-shared asset, or one historical version
--uuid <u> --out <parent-dir> — files always land in <parent-dir>/<identifier>/; add --version <N> to grab version N as a single file or zip at <parent-dir>/<identifier>-v<N>[.zip|.<ext>]
Script gotcha: metadata values are interpolated into JSON without escaping — --identifier, --description, --entry-point, and --note values must contain no double quotes or backslashes (the scripts now reject them rather than corrupt the payload). If the description needs them, upload with a plain placeholder and set the real text afterward via asset_update (which is JSON-safe).
Workflow: Publish a New Asset
Identify the source. Confirm the path exists. Classify:
Contains HTML → --type website. Determine the entry point (default index.html; if the main file has another name, pass --entry-point <file>).
Files for storage/distribution rather than viewing (docs, zips, datasets, binaries) → --type storage: no entry point, never served as a site; delivered via <base>/download/<uuid> when public, or via previewUrl/share link when private.
Check for existing work — apply the Cache Rule (see above). If the user confirms an existing asset is what they meant, switch to that asset (show link, then update/share/etc.) instead of publishing. Only continue here once it's confirmed new.
Suggest an identifier. The identifier is user-facing — it appears in the public URL <base_url>/sites/<identifier>-<uuid>/. Heuristics:
kebab-case, lowercase, ≤50 chars, no quotes/backslashes
Prefer the HTML <title> or H1 if meaningful; else the source folder basename
Strip dates, tmp/final/v2 noise suffixes
Must not collide with existing identifiers — reuse the assets_list result from step 2 (no second call); identifiers are unique per user
Ask the user (two AskUserQuestion calls):
First — identifier: offer your suggestion first (<suggestion> (Recommended)), 1-2 sensible alternates; the user can always type their own via Other.
Second — one question: privacy.
Workspace (Recommended) — "Your team can find, open, and reuse it — this is what makes the asset cache work."
Public — "Anyone with the URL can view."
Only me — "Just you; others need a share link."
Status is NOT asked — default published. Only mention unpublished if the user says "draft"/"not ready yet" (set it via --status unpublished or later via asset_update).
Draft the description. 1-2 sentences saying what the asset is and who it's for (e.g. "Interactive use-case explorer for Acme's platform, built for the Q3 ABM campaign"). Sanitize for the script (no " or \).
Mint the token (asset_generate_access_token) and resolve the base URL. Do this AFTER steps 1-5 — the step-2 assets_list already rotated any earlier token, and no MCP asset calls may follow the mint before the upload runs.
Upload.
Source is already a .zip → upload-artifact.sh --src <file>.zip ...
Source is a folder → zip-and-upload-artifact.sh --src <folder> ... (fall back to upload-artifact.sh per-file multipart only if zipping fails)
Always pass explicitly: --type, --identifier, --description, --privacy, --status, and --entry-point for websites. Never rely on script defaults — --type in particular defaults to website, and type is immutable after create, so a storage bundle uploaded without it can only be fixed by delete-and-recreate.
Record and report. Update the registry (uuid, identifier, description, type, privacy, status, url). Then ALWAYS report the link:
Published + public → Public — anyone with the link can view: <siteUrl> (website) or <base>/download/<uuid> (storage)
Workspace tier → the siteUrl (teammates verify their work email once) plus Preview: <previewUrl> from the upload output's preview: line
Only me or unpublished → Preview (you + workspace members): <previewUrl> from the upload output's preview: line, and offer a share link now for anyone else (see Shares workflow)
The Exact Publish Sequence — the ENTIRE publish is these actions and nothing else:
1. assets_list ← MCP tool call (Cache Rule)
2. AskUserQuestion (identifier) ← offer suggestion + alternates
3. AskUserQuestion (privacy) ← workspace (recommended) | public | only_me
4. asset_generate_access_token ← MCP tool call; capture accessToken from the result
5. ONE bash command ← ARTIFACTS_ACCESS_TOKEN='<accessToken>' \
bash "${CLAUDE_PLUGIN_ROOT:-.}"/skills/asset-manager/scripts/zip-and-upload-artifact.sh \
--src … --type … --identifier … --description … --privacy … --status published [--entry-point …]
6. Update the registry, report the link
A publish that creates more than one asset, or runs any script outside the bundled four, is off the rails — stop and restart from this sequence. (The documented recoveries are NOT off the rails: the zip → upload-artifact.sh per-file fallback when zipping fails, and a single 401/502 retry, each stay within this one publish.)
Workflow: Update an Asset's Files
Resolve the asset (registry first; asset_get_by_id / assets_list if unsure).
Warn: full replace. Files not included in --src are pruned from the asset's current file set. The previous set survives as a restorable version (see Versions & Rollback), but the live URL changes immediately — confirm with the user if the source folder looks partial.
Mint token, then: update-artifact.sh --uuid <uuid> --src <folder-or-zip> --note "<what changed>". Every file update mints an immutable version and --note is its changelog line — always pass one (sanitized like the other metadata flags: no " or \).
Update the registry (updated date, any changed url) and report.
Workflow: Versions & Rollback
Every file update mints an immutable version — an upload never overwrites history. Two fields on every asset response tell the story:
currentVersion — what the bare URL serves right now
latestVersion — the mint high-water mark; higher than currentVersion exactly when the asset has been rolled back
The operations (all MCP tools, except the version download):
History: asset_versions_list — every version with its note (from --note at update time).
Rollback: asset_version_restore — instant: repoints the bare URL at the chosen version, no bytes move. Newer versions stay restorable (roll forward the same way), and the next file update mints from the high-water mark (latestVersion + 1) — a rollback never loses work.
Pin a version in a URL: append @vN/ after the /sites slug or a vanity slug — e.g. <base>/sites/<identifier>-<uuid>/@v2/ or /s/acme/q3-deck/@v2/. The bare URL always serves currentVersion.
Download a version's files: mint token, then download-artifact.sh --uuid <uuid> --version <N> --out <parent-dir> — arrives as ONE download, the version's single file or a .zip of everything, saved as <parent-dir>/<identifier>-v<N>[.zip|.<ext>] (not unpacked).
Cleanup: asset_version_delete frees an old version's storage. The CURRENT version can never be deleted (400) — restore a different version first if that is really the goal.
Retention: the service auto-prunes versions past ~20, so history is a rollback safety net, not an archive — download anything that must be kept forever.
Workflow: Metadata & Privacy (MCP only)
For identifier, description, entry point, privacy, status, or vanity slug changes use asset_update (type is immutable). Notes:
Changing the identifier changes the public URL — tell the user the old link breaks.
Status: unpublished hides the asset from the workspace gallery (it stays viewable via preview/workspace links); published is the discoverable state. Status never changes who can access — that's privacy.
When moving DOWN the ladder (public → workspace, or anything → only_me), explain who loses access, then ask who keeps it:
workspace: the URL stops working for the outside world; workspace members still open it after verifying their work email, and teammates keep API access.
only_me: everyone but the owner loses access — teammates too (no API read, no preview).
Anyone else needs a share link (emails and/or allowed domains, email-verified) — works on any non-public tier.
Then ask WHO to share with (emails/domains) and whether the link should ever expire (default: never) → Shares workflow. Report the fresh previewUrl for teammates alongside the share link.
When flipping to public, mention existing share links keep working but are no longer needed.
Workflow: Vanity URLs
asset_update accepts vanitySlug (a string sets it, null clears it) to give an asset a pretty URL: /s/<workspace-handle>/<slug>/.
Slug rules: lowercase [a-z0-9-], ≤63 chars, no reserved words (the server rejects those). Unique per workspace (not per user) — a taken slug returns 409: pick another (suggest a variant).
The response's vanityUrl carries the resulting pretty URL — it appears only when the workspace has a handle. Slug set but vanityUrl null → the workspace has no handle yet; the slug is stored and the URL lights up once an admin sets one in Octave.
@vN after the slug pins a version: /s/acme/q3-deck/@v2/ (see Versions & Rollback).
Renaming a slug retires the old URL — like an identifier change, tell the user the old vanity link breaks. Clearing (null) does the same.
Record vanitySlug in the registry and, whenever an asset has a vanityUrl, report it alongside the canonical link — it is the one to hand out.
Workflow: Shares (non-public assets)
Share links grant specific outside people access to any non-public asset (both only_me and workspace tiers) after they verify their email. Create a share:
Ask who gets access (AskUserQuestion): Specific emails / Whole domains ("everyone @company.com — avoids listing every address") / Both. Then collect the comma-separated emails and/or domains as free text.
Expiry defaults to never — don't ask unless the user raises it (or the content is obviously time-boxed); a share accepts expiresInDays 1-3650 when they want one.
Call asset_share_create (uuid, emails?, domains?, expiresInDays only if chosen). At least one email or domain is required.
The response url is shown exactly once and can never be retrieved again. Write it to the registry in the same turn, BEFORE replying to the user. Then give the user the share URL.
Manage existing shares (share uuids come from the registry or asset_shares_list):
Remove people: asset_share_remove_recipients / asset_share_remove_domains — a share must keep ≥1 email or domain; to remove the last one, suggest asset_share_revoke instead
Revoke: asset_share_revoke — confirm first (cuts off active viewer sessions immediately, irreversible)
Update the registry after every share mutation.
Workflow: Access Requests
An access request is a knock on the door: a code-verified viewer opened an asset they can't access (workspace or share flow) and asked to be let in. Requests are owner-only to act on.
The inbox: asset_access_requests_list — a cross-asset rollup; filter status: pending for what needs action (other statuses: granted, dismissed). Each entry embeds the asset uuid + identifier plus the requester's verified email, so no per-asset lookup is needed.
Grant: asset_access_request_grant mints a fresh single-recipient, never-expiring share for the requester's email. The response's share URL appears exactly once and NO email is sent — same one-time rule as asset_share_create: write it to the registry in the same turn, then ALWAYS give the URL to the user to forward to the requester; without that hand-off the grant reaches no one. Granting an already-granted request → 409 (the share exists; find it via asset_shares_list).
Dismiss: asset_access_request_dismiss is "not now", not a block — the requester can knock again, which flips the request back to pending. Dismissing a granted request → 409; to take access away, revoke the share instead (Shares workflow).
Surface pending requests whenever the user asks anything like "who wants access" / "any requests on my deck?", and offer grant/dismiss per request.
Workflow: Who Opened It (Stats & Visitors)
Two owner-only reads answer "how is my asset doing" — pick by the question:
How many → asset_stats_get: per-day unique visit and download counts. Trends, not names.
Who → asset_visitors_list: the identified viewers — share recipients who code-verified (via: share) and workspace members who verified their work email (via: workspace).
Anonymous public visitors are counted in stats but never identified — never imply the visitor list is complete for a public asset. The honest phrasing: "N visits, of which these verified viewers: …".
Workflow: Download / List / Delete
Download: mint token, then download-artifact.sh --uuid <uuid> --out <parent-dir> — files always land in <parent-dir>/<identifier>/. Works for any asset the user owns or any non-only_me asset in their workspace, regardless of status/privacy. Add --version <N> for a historical version's files (see Versions & Rollback).
List: "what assets are available / do we have X?" → run a fresh assets_list and show EVERY asset with its identifier, owner ("me" vs teammate), and link — no row without a link: published + public → the public URL ("anyone with the link"); everything else → the previewUrl from that same list response. Reconcile the registry while you're at it. The registry alone is only enough for quick recall of what was published from this project.
Delete: asset_delete — irreversible, deletes the files too. Always confirm with the user first. Then remove the entry from the registry.

Memory Registry
Persistent registry shared with the asset-manager agent, at:
This is the .claude directory of the current project (where you are working) — NEVER ~/.claude/... in the home directory. Before creating a registry anywhere, READ the project path first: if it exists, use it — it may already hold published assets and the token prefix. Never maintain two registries. Create it (and parent directories) only when the project path genuinely has none. Format:
After EVERY successful mutation (upload, file update, metadata change, vanity slug change, share create/add/remove/revoke, access-request grant/dismiss, version restore/delete, delete, token mint) update the registry in the same turn, before the user-facing report.
Store only the token prefix + expiresAt — never the plaintext token.
The share url (from asset_share_create or asset_access_request_grant) exists nowhere else after creation — losing it means revoking and re-creating the share.
Never store previewUrl — it is short-lived and minted per read; fetch a fresh one with asset_get_by_id when needed.
The registry is a local, per-project cache — assets created from other projects or sessions won't be in it. It is never sufficient for the Cache Rule's dedup check; that always uses a fresh assets_list.
Reconciliation:
Answer read questions ("what have I published?") from the registry.
Run assets_list and reconcile when: last_reconciled is more than 7 days old, a tool result contradicts the registry, or a known uuid returns 404.
Reconcile = add assets missing from the registry, drop entries missing from the API (note "deleted outside this skill"), refresh status/privacy/url, bump last_reconciled.
A share found via asset_shares_list with no url in the registry → mark url: lost — revoke and re-create to get a new link.
Output Style
Always end a publish/share operation by presenting the working URL plus a one-line summary of identifier, privacy, and status. Label public links Public — anyone with the link can view; label workspace links Workspace — teammates verify their work email once; for only_me/unpublished assets give the fresh previewUrl instead.
When an asset has a vanityUrl, show it alongside the canonical link labeled Vanity: — it is the memorable one to hand out.
Report every assumption made (e.g. auto-detected entry point) so the user can correct it.
