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 | $0.00088 | $0.02925 |
| Opus 5.5 | $0.00035 | $0.01170 |
| Sonnet 5.5 | $0.00018 | $0.00585 |
| Haiku 4.5 | $0.00009 | $0.00293 |
Grade A, and why
hex-execute 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 11d 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 — 245 lines — stays where its author put it; the contents beside it link to each section on GitHub.
hex-execute — Execution Orchestrator
Thin dispatcher. A plan is a few pipelines cut along contracts; a pipeline
is a chain of steps in one worktree. This file resolves the target, runs
the contract wave, dispatches steps, merges, runs the integration gate
concurrent with the review call, fixes, and hands to /hex-finalize.
Vocabulary lives in hex-core and is linked here, never copied.
Shared contracts:
protocol.md ·
workers.md ·
models.md ·
memory.md ·
worktree.md ·
verify.md.
If hex-core is not installed: grim add ghcr.io/michael-herwig/arcana/hex-core:latest.
Argument syntax
/hex-execute [target] [--dry-run]
- target (optional): a plan artifact path; a free-text task (no plan
artifact, one pipeline); or omitted — resolve the active-plan pointer from
hex.md › Memory(memory.md). --dry-run— print the announce block and stop; no worker launches.
The run
Counts are fixed (DESIGN.md): two full gates (integration,
release), ≤ 3 review calls, workers never wait, escalation by the
orchestrator only.
1. Resolve memory and target
Locate .agents/memory/hex.md searching upward; a missing file is normal
(memory.md) —
use shipped defaults and note that /hex-init can create one. When present,
read it whole: Pointers (verification, hub/generated files, fresh-build
switch, worktree location), Preferences (model-class agent definitions,
limits), Memory (active-plan pointer). A Federation lead: bullet means this
repo is a satellite: halt per
memory.md.
Resolve the target: explicit plan path (read it whole), active-plan pointer
(none recorded: stop and ask), or free text (scope contracts inline).
A plan carrying a Repo column: follow federation.md before
anything else is written.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

hex-execute is a skill published in the GitHub repository grimoire-rs/grimoire (14 stars, last pushed 6d ago), licensed Apache-2.0. It adds 88 tokens to every session and 2,925 once invoked, about $0.0004 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 2026-09-08.
