An upgrade command for Memex workspaces, which are folders managed with structured notes and indexes. It detects the workspace’s current version and runs the needed update steps.

Use it to update old Memex summaries and indexes, check whether an upgrade is needed, run a dry run, or stop when the workspace is not managed by Memex.

It avoids manually guessing which maintenance operations are required and makes repeated upgrades safe and efficient.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00058	$0.02289
Opus 5.5	$0.00023	$0.00916
Sonnet 5.5	$0.00012	$0.00458

Security

Grade A, and why

upgrade scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Memex - Upgrade

Wikilink rule: When referencing files in any markdown you write, use [[filename]] format.

Bring a workspace from any older Memex layout to the current one in a single, idempotent pass. The skill is a thin orchestrator over /memex:resummarize and /memex:reindex; it adds state detection (so re-runs are cheap) and sequencing (resummarize before reindex so closets entries inherit the v2 summary rules).

For the v1 → v2 upgrade specifically, see references/v1-to-v2.md. For the v2.0 → v2.1 increment, see references/v2-to-v2_1.md. Future major versions add their own playbooks under references/.

Step 0: Detect workspace, parse arguments

Run WORKSPACE_ROOT=$(pwd) && echo "$WORKSPACE_ROOT" via Bash.

Read _MANIFEST.md. If the file is missing or has no <!-- memex-managed marker, tell the user "Memex isn't managing this workspace yet. Run /memex:init to set up." and stop.

Acquire memory/.upgrade.lock and check the 24-hour cooldown in memory/.upgrade-runs.log. Both follow the shared bulk-write convention. See ../consolidate/references/locking.md.

Parse $ARGUMENTS:

--dry-run. Detect state and print the upgrade plan, but do not execute. Skip the lock acquisition.
--force. Re-run every step regardless of state. Useful after a closets format change, or to verify cleanliness.

Step 1: Detect state

Read five signals from the workspace:

Manifest version marker.  from _MANIFEST.md. Compare to the current Memex VERSION. If older or missing, the workspace was scaffolded by an earlier Memex release.
Summary format version.  from _MANIFEST.md. If missing or < 2, summaries follow pre-v2 conventions and need /memex:resummarize.
Closets coverage. For each row in the Hub Map, check whether <hub>/_CLOSETS.md exists. Count hubs with coverage vs hubs without.
Closets format version. For each existing _CLOSETS.md, read the  marker. If < 1.1 and the hub has > 30 files, pagination needs to engage.
Memory closets (2.1+). Check whether memory/_CLOSETS.md exists. If missing on a manifest version < 2.1.0, this signals a v2.0 → v2.1 migration step.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

upgrade is a skill published in the GitHub repository Skyfox-io/Memex (17 stars, last pushed 4mo ago), licensed MIT. It adds 58 tokens to every session and 2,289 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
