Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00041 | $0.01096 |
| Opus 5 | $0.00020 | $0.00548 |
| Sonnet 5 | $0.00008 | $0.00219 |
| Haiku 4.5 | $0.00004 | $0.00110 |
Grade A, and why
ingest 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 3d 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.
How it starts
The opening of the file, as written. The whole thing — 110 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are running /hypo:ingest. Save a raw source and synthesize it into wiki pages.
What this does
- Saves raw source content to
sources/<slug>.<ext>(never edited after) - Synthesizes the source into one or more pages in
pages/ - Updates
index.mdwith new or updated pages - Appends an entry to
log.md
Step 1 — Collect source details
Ask the user:
- Source: "What is the source? (paste text, provide a file path, or give a URL)"
- Slug: "What slug should this source have? (e.g.
openai-swarm-paper,team-retro-2026-04)"- Default: derive from title or filename
Do not fetch the URL or read the file yet — the privacy guard in Step 2 must run first.
Step 2 — Privacy guard (.hypoignore)
Bundled scripts here run via ${CLAUDE_PLUGIN_ROOT}/scripts/. To resolve that package root: if ${CLAUDE_PLUGIN_ROOT} is already an absolute path, use it; otherwise read pkgRoot from ~/.claude/hypo-pkg.json (only when non-empty and the target script exists under it); otherwise use the hypo@hypomnema (or legacy hypomnema@hypomnema) installPath in ~/.claude/plugins/installed_plugins.json; if none resolve, stop and tell the user to run hypomnema upgrade --apply (or /hypo:upgrade on a plugin install) or reinstall instead of guessing the cache layout.
Refuse to ingest secrets (.env, SSH keys, credentials) before they ever reach sources/. Run the guard for both the input path and the destination path:
-
If the source is a file path, check it (use an absolute path):
node ${CLAUDE_PLUGIN_ROOT}/scripts/ingest.mjs [--hypo-dir="<path>"] --check="<absolute-input-path>" -
Always check the destination
sources/<slug>.<ext>:node ${CLAUDE_PLUGIN_ROOT}/scripts/ingest.mjs [--hypo-dir="<path>"] --check="sources/<slug>.<ext>"
If either command exits non-zero, stop: surface the Refused: ... message to the user and do not fetch, read, or save the source. The slug check matters because a user could rename a .env to an innocuous slug — the destination must still be blocked.
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.

ingest is a command published in the GitHub repository sk-lim19f/Hypomnema (10 stars, last pushed 3d ago), licensed MIT. It adds 41 tokens to every session and 1,096 once invoked, about $0.0002 per session on Opus 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 2026-08-31.
Other commands, from other repositories
minutes-ideas
Surface recent voice memos and ideas captured from any device. Use when the user asks "what ideas did I have?", "what were my recent memos?", "what did I record while walking?", or wants to recall a captured thought.
learn
Force claude-smart to extract learnings from this session now.
memory-store
Store an insight, decision, or pattern to memory.
cc-memory
Configure persistent memory that survives across sessions using a layered approach: split rule files for always-loaded context, auto-memory for organic learning, and optional MCP-backed long-term memory for large codebases.
analyze-context
USE WHEN you want to analyze project context before starting work on a task. Calls context + recall, then synthesizes goals, decisions, gotchas, and relevant memories into a pre-task brief.
music-suno-prompt
Grounded Suno prompt synthesis from local knowledge corpus + persona canon + label canon. No vibes-prompting.
