Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.01687 | $0.01687 |
| Opus 5 | $0.00843 | $0.00843 |
| Sonnet 5 | $0.00337 | $0.00337 |
| Haiku 4.5 | $0.00169 | $0.00169 |
Grade A, and why
episodic-memory CLAUDE.md 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 — 130 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Project Instructions: episodic-memory
A Claude Code plugin that gives semantic search across past Claude Code conversations. This file holds the conventions an AI assistant needs to work on this codebase safely.
Quick orientation
- TypeScript source in
src/, compiled todist/bytsc && esbuild. Both are committed. - CLI entry points in
cli/(Node.js wrappers — no bash). - MCP server is
dist/mcp-server.js, launched bycli/mcp-server-wrapper.jsfrom the plugin manifest. - Tests live in
test/, run viavitest. - Generated files live in
dist/andsrc/version.ts. The latter is gitignored; never edit it.
Build and test
npm test # full suite, runs prebuild step that generates src/version.ts
npm run build # tsc + esbuild bundle
npm run generate-version # writes src/version.ts from package.json
The prebuild and pretest hooks both regenerate src/version.ts. After source changes that touch the MCP server or any imported module, run npm run build so dist/ reflects source. Commit dist/ alongside src/.
Version management
Three files hold the plugin version, all kept in lockstep:
package.json.claude-plugin/plugin.json.claude-plugin/marketplace.json(plugins[0].version)
Plus a fourth thing outside this repo:
../superpowers-marketplace/.claude-plugin/marketplace.json(the user-visible install registry)
To bump in this repo:
./scripts/bump-version.sh X.Y.Z # updates all three local files
./scripts/bump-version.sh --check # report current versions
./scripts/bump-version.sh --audit # scan for stale references
The script reads .version-bump.json for the file list and audit excludes. MCP server identity (the version field in new Server({...}) in src/mcp-server.ts) is derived from src/version.ts, which the prebuild script generates from package.json — keep that pipeline in place; never hardcode the version.
Release engineering
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.

episodic-memory CLAUDE.md is an instructions file published in the GitHub repository obra/episodic-memory (470 stars, last pushed 3mo ago), licensed MIT. It adds 1,687 tokens to every session, about $0.0084 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 2026-08-30.
