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 | $0.00066 | $0.00411 |
| Opus 5 | $0.00033 | $0.00205 |
| Sonnet 5 | $0.00013 | $0.00082 |
| Haiku 4.5 | $0.00007 | $0.00041 |
Grade A, and why
install 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 2d 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.
What it actually says
Install Rekal
Rekal is git-backed memory of prior AI sessions: why a change was made, what was
tried, what was rejected. This installs the binary. Setting up a repository is a
separate step — the init skill.
Ask first
The installer downloads a release archive and writes an executable to the user's machine. Say that plainly, then wait for an answer.
If the user declines, stop. Say Rekal is not available and answer from the tree. Declining is a complete answer.
Run it
The plugin ships the installer on PATH:
rekal-install
That is a vendored copy of the project's own scripts/install.sh — it detects
the platform, downloads the matching release from GitHub, and verifies it
against the published checksums. Installs to ~/.local/bin; pass
--target <dir> to override.
Requires git, macOS or Linux. The archive is large (~160 MB — the binary embeds an embedding model), so the download takes a moment.
Verify
rekal version
If the shell reports command not found after a successful install, the install
directory is not on PATH. Tell the user which directory to add and let them
edit their own shell profile. Do not edit it for them.
Next
The binary is installed but no repository uses it yet. If the user wants memory
in the current repo, continue with the init skill. Ask before running it —
that is a separate decision about a separate thing.
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.

install is a skill published in the GitHub repository rekal-dev/rekal-cli (140 stars, last pushed 28d ago), licensed Apache-2.0. It adds 66 tokens to every session and 411 once invoked, about $0.0003 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.
Other skills, from other repositories
video
Use when a brief has to become a film. Turns a one line ask into a Claude Design prompt written in the animations-v3 engine's own language, plus the built piece.jsx and a contact sheet to look at before anyone renders. Covers reference roles, the kit, the storyboard gate, the motion floor, and the verification…
emulo
Use when the user explicitly asks to run, set up, update, re-mine, or deepen Emulo from real local AI coding-session history and native emulo:mine is not available. This is the cross-agent skills.sh bootstrap, not the native namespaced plugin.
emulo
Load the user's Emulo profile, mined from their local Claude Code, Codex, and OpenCode session logs, so you work like them instead of a cold start. Use before working on their task.
mine
Use only when the user explicitly asks to run, set up, update, re-mine, or deepen Emulo from real local AI coding-session history.
write
Use for marketing, social, replies, product copy, launch copy, and writing in the user's voice when their Emulo writing profile should guide the task. Do not use for unrelated execution or UI/UX design alone.
design
Use for UI, UX, visual hierarchy, frontend-design judgment, references, redesigns, and design critique when the user's Emulo taste should guide the task. Do not use for unrelated execution or marketing/social writing alone.
