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 | $0.00744 | $0.00744 |
| Opus 5 | $0.00372 | $0.00372 |
| Sonnet 5 | $0.00149 | $0.00149 |
| Haiku 4.5 | $0.00074 | $0.00074 |
Grade A, and why
memento copilot-instructions.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 4d 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 — 43 lines — stays where its author put it; the contents beside it link to each section on GitHub.
GitHub Copilot Instructions
This file is read automatically by GitHub Copilot in VS Code and other Copilot-enabled environments.
The canonical instruction set for all AI agents working on Memento lives in AGENTS.md at the repository root. This file exists only to point Copilot at it; everything below is a brief summary. Do not duplicate content here — read AGENTS.md directly.
Read this first
AGENTS.md— guiding principles, architectural rules, common pitfalls, verification commands.ARCHITECTURE.md— high-level architecture and links into the deeper docs.docs/adr/— every architectural decision and why it was made.
Path-specific guidance
When you edit files in these areas, the canonical reference is:
**/*.test.ts—AGENTS.md§ "Architectural rules" + § "Verification"; tests must use Vitest, mirror the source layout underpackages/<pkg>/test/, and keep the 90/90/90/90 coverage gate green.packages/core/src/storage/migrations/**— ADR-0001 and existing migrations under that directory; migrations are forward-only and must include matching tests underpackages/core/test/storage/migrations/.packages/core/src/commands/**— ADR-0003 andpackages/core/README.md; every command lands in the single registry and is projected to MCP and CLI by adapters.docs/**— generated reference docs underdocs/reference/are produced bypnpm docs:generate(do not hand-edit); architectural prose underdocs/architecture/and ADRs underdocs/adr/follow the templates already in those directories.
Reusable workflows
These live as concise checklists rather than executable prompt files:
- Add a command: define schemas in
@psraghuveer/memento-schema, register the command inpackages/core/src/commands/, add tests, runpnpm docs:generateto refreshdocs/reference/cli.mdanddocs/reference/mcp-tools.md. ADR-0003 is the contract. - Add a config key: add a
defineKeyentry topackages/schema/src/config-keys.ts, follow the JSDoc-style guidance at the top of that file, thenpnpm docs:generateto refreshdocs/reference/config-keys.md. - Add a migration: add the next-numbered migration under
packages/core/src/storage/migrations/with a matching test underpackages/core/test/storage/migrations/. Migrations are forward-only.
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.

memento copilot-instructions.md is an instructions file published in the GitHub repository veerps57/memento (22 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 744 tokens to every session, about $0.0037 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.
