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.

What it costs to keep this loaded
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 | $0.00051 | $0.00392 |
| Opus 5 | $0.00026 | $0.00196 |
| Sonnet 5 | $0.00010 | $0.00078 |
| Haiku 4.5 | $0.00005 | $0.00039 |
Grade A, and why
motif-for-codex 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 5d 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
Motif workbench
The connected Motif MCP server provides two workbench tools:
motif_open_workbenchaccepts Motif payloads or supported sequence content and opens the interactive MCP App workbench.motif_create_workbench_artifactreturns a self-contained HTML resource for the same inputs. Use it when the user asks for a portable artifact or when a host needs an HTML resource.
Prefer motif_open_workbench for interactive sequence work. Confirm that the
workbench is visible after the tool succeeds. If the host cannot display it,
call motif_create_workbench_artifact with the same input and offer the
portable HTML resource.
Codex can find, prepare, analyze, and transform records with its available tools, then open the records and results in Motif. When a task refers to a record that is not available, find the requested record with the tools available in the session or ask which source to use.
Minimal requests users can copy are:
Open this sequence in Motif: >example
ATGAAATTTGGGCCCTAA
Create a portable Motif HTML workbench artifact for: >example
ATGAAATTTGGGCCCTAA
After opening Motif, confirm the record names, sequence lengths, annotations, alignments, and active view. Report any import error with the field or record that needs correction.
Use Motif tools for workbench creation and display. Use Codex's other tools for retrieval, file operations, analysis programs, and browser interaction.
What ships with it
2 files 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.

motif-for-codex is a skill published in the GitHub repository jvogan/motif (48 stars, last pushed 3d ago), licensed MIT. It adds 51 tokens to every session and 392 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 2026-09-03.
