A command that rebuilds the per-section indexes used by Memex search. An index is a prepared list of important files and links that helps retrieval find information quickly.

Use it after a large import, during a first-version-to-second-version upgrade, or whenever you need complete search indexes immediately.

It fills in missing indexes across the workspace instead of waiting for many session cleanups to build them gradually.

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	$0.01953
Opus 5.5	$0.00023	$0.00781
Sonnet 5.5	$0.00012	$0.00391
Haiku 4.5	$0.00006	$0.00195

Security

Grade A, and why

reindex 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.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/extract-graph.py, scripts/verify-wikilinks.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 164 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Memex - Reindex

Wikilink rule: When referencing any file in markdown, always use [[filename]] wikilink format.

Walk every Tier 2 hub in _MANIFEST.md and (re)generate _CLOSETS.md for each. Session-end refreshes touched hubs incrementally; reindex covers the long tail in one pass.

Picking the right migration tool:

/memex:resummarize. Rewrites manifest + hub summaries to v2 format.
/memex:reindex. Rebuilds the per-hub closets index used for retrieval.

Run resummarize for summary format upgrades, reindex for closets coverage. They're independent; on a fresh v1→v2 migration, run resummarize first, then reindex.

Step 0: Detect workspace, acquire lock, parse arguments

Run WORKSPACE_ROOT=$(pwd) && echo "$WORKSPACE_ROOT" via Bash. Read _MANIFEST.md:

Missing or no <!-- memex-managed marker: Tell the user "Memex isn't initialized here. Run /memex:init first." and stop.

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

Parse $ARGUMENTS:

--hub <name>. Limit to one hub (e.g., --hub fundraising). Useful for spot rebuilds.
--force. Rebuild every entry from scratch, ignoring mtime checks. Also bypasses the 24-hour cooldown.

Step 1: Build the hub list

Read _MANIFEST.md. For each row in the Hub Map, parse the wikilink in the Hub column:

Legacy form [[<domain>-index]]. Hub folder = parent of the index file. Closets file: <hub-folder>/_CLOSETS.md.
Closets-only form [[<domain>/_CLOSETS]] (v2.1+). Hub folder = the parent folder of the closets file. No index file expected.

Resolve absolute paths for each hub folder and its closets / archive. Archive (if any): <hub-folder>/_CLOSETS-archive.md.

Also include memory/ as a synthetic hub. Its closets file is memory/_CLOSETS.md; its files are the Tier 1 files listed in _MANIFEST.md (status, session-log, decisions, glossary, plus any user-added Tier 1 entries). The memory hub has no archive (Tier 1 is a small fixed set, not paginated).

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

reindex 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 1,953 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.
