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 | $0.00070 | $0.00376 |
| Opus 5.5 | $0.00028 | $0.00150 |
| Sonnet 5.5 | $0.00014 | $0.00075 |
| Haiku 4.5 | $0.00007 | $0.00038 |
Grade A, and why
apply-comments 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 1mo 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
Apply the comments left in the viewer
Notes left through the viewer's inspect mode are written into the workbook source as markers:
// @sheet-comment: this should be a percentage, and rounded to one decimal
col('margin', { header: 'Margin', formula: (r) => div(…) }),
Workflow
- Find them. Search
sheets/<id>/index.tsxfor@sheet-comment. If the user did not name a workbook, use thecurrent-sheetskill. - Read them all before changing anything. Two comments often describe one change, and a later one can contradict an earlier one.
- Apply each in the authoring layer. The comment sits next to the construct
it is about — a
col, adataentry, a<Cell>. Change that construct, not a coordinate. - Delete the marker once the edit is made. A stale marker gets re-applied next time and the edit lands twice.
- Ask, do not guess. If a comment is ambiguous ("this looks off"), leave the marker in place and ask what they meant. A wrong edit to a financial model is worse than an unapplied one.
After
Summarise what you changed, one line per comment, and name anything you left alone and why.
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.

apply-comments is a skill published in the GitHub repository lianghsun/open-sheet (127 stars, last pushed 2mo ago), licensed MIT. It adds 70 tokens to every session and 376 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 2026-08-30.
