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 5.1 | $0.00080 | $0.00869 |
| Opus 5.5 | $0.00032 | $0.00348 |
| Sonnet 5.5 | $0.00016 | $0.00174 |
| Haiku 4.5 | $0.00008 | $0.00087 |
Grade A, and why
lockin 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.

No licence file
A repository with no LICENSE is all rights reserved by default, so the body is not copied here. The metadata, the measurements and the link are.
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.

lockin is a skill published in the GitHub repository codiume/skills (7 stars, last pushed 5d ago), with no licence file. It adds 80 tokens to every session and 869 once invoked, about $0.0003 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 2026-10-21.

handoff
Distills the current session's goal, state, remaining plan, key files, and gotchas into a copy-pasteable markdown handoff for a fresh agent or teammate, written to .agent/{branch}/handoff.md and the clipboard. Invoke with /handoff [focus phrase] [--brief].
life-design
Walk you through the Stanford Designing Your Life method and write your Personal Life Design Blueprint — three Odyssey plans and the prototypes to test them.
prompt-optimizer
Analyze a draft prompt, diagnose gaps, match it to relevant skills already in this catalog, and output a ready-to-paste improved prompt — advisory only, never executes the task itself. Use when the user says "optimize this prompt", "improve my prompt", "how should I prompt for X", or pastes a draft prompt asking for…
strategic-compact
Use when deciding whether to manually compact conversation context now versus later — at a phase boundary (research done, plan written, milestone shipped), before switching to an unrelated task, or when responses feel slower/less coherent from context pressure. Trigger phrases include "should I compact now", "context…
current-slide
Resolve which slide, page, and (optionally) selected element the user is currently viewing in the open-slide dev server. Consult this whenever the user references "this page", "this slide", "this element", "the slide I'm on", "the current page", or any deictic reference to slide content without naming it. Re-read…
obsidian-bases
Create and edit Obsidian Bases (.base files) with views, filters, formulas, and summaries. Use when working with .base files, creating database-like views of notes, or when the user mentions Bases, table views, card views, filters, or formulas in Obsidian.
