Poco is a self-hosted collaborative AI workspace designed as an alternative to OpenClaw, with chat channels, task management, file handling, and a web interface. Its Claude Code–based agent works inside an isolated sandbox and can use project files, skills, MCP tools, and sub-agents.
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 | $0.00148 | $0.02157 |
| Opus 5.5 | $0.00059 | $0.00863 |
| Sonnet 5.5 | $0.00030 | $0.00431 |
| Haiku 4.5 | $0.00015 | $0.00216 |
Grade A, and why
minimax-xlsx 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.
This is a copy
100% identical to minimax-xlsx — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 139 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Task Routing
| Task | Method | Guide |
|---|---|---|
| READ — analyze existing data | xlsx_reader.py + pandas |
references/read-analyze.md |
| CREATE — new xlsx from scratch | XML template | references/create.md + references/format.md |
| EDIT — modify existing xlsx | XML unpack→edit→pack | references/edit.md (+ format.md if styling needed) |
| FIX — repair broken formulas in existing xlsx | XML unpack→fix <f> nodes→pack |
references/fix.md |
| VALIDATE — check formulas | formula_check.py |
references/validate.md |
READ — Analyze data (read references/read-analyze.md first)
Start with xlsx_reader.py for structure discovery, then pandas for custom analysis. Never modify the source file.
Formatting rule: When the user specifies decimal places (e.g. "2 decimal places"), apply that format to ALL numeric values — use f'{v:.2f}' on every number. Never output 12875 when 12875.00 is required.
Aggregation rule: Always compute sums/means/counts directly from the DataFrame column — e.g. df['Revenue'].sum(). Never re-derive column values before aggregation.
CREATE — XML template (read references/create.md + references/format.md)
Copy templates/minimal_xlsx/ → edit XML directly → pack with xlsx_pack.py. Every derived value MUST be an Excel formula (<f>SUM(B2:B9)</f>), never a hardcoded number. Apply font colors per format.md.
EDIT — XML direct-edit (read references/edit.md first)
CRITICAL — EDIT INTEGRITY RULES:
- NEVER create a new
Workbook()for edit tasks. Always load the original file. - The output MUST contain the same sheets as the input (same names, same data).
- Only modify the specific cells the task asks for — everything else must be untouched.
- After saving output.xlsx, verify it: open with
xlsx_reader.pyorpandasand confirm the original sheet names and a sample of original data are present. If verification fails, you wrote the wrong file — fix it before delivering.

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.

minimax-xlsx is a skill published in the GitHub repository poco-ai/poco-claw (1,356 stars, last pushed 7d ago), licensed MIT. It adds 148 tokens to every session and 2,157 once invoked, about $0.0006 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 100% identical to minimax-xlsx, differing in 0 lines, and is treated as a copy.
