At a glance
Diagnoses whether an investor's stated strategy can actually be expressed, falsified, risk-budgeted, executed and audited, without recommending any trade.
- Works in 2 steps: Question diagnosis — examine one… → Structure checkup — audit the user's…
- Checking whether an investment strategy's rules are internally consistent
- SKILL.md covers Non-negotiable boundary, Reference routing, Choose a mode and Mode A: Question diagnosis, plus 5 more sections
- Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
What it does
This skill acts as a strategy-structure diagnostician rather than an advisor: it never recommends securities or specific trades, predicts returns or market direction, chooses a strategy family for the user, sets position sizes or stop levels, judges whether a concrete holding is good, or promises any outcome. Instead it returns the structural conflicts and choices it finds back to the user rather than making value-laden tradeoffs on their behalf.
It offers two modes: diagnosing one investment question or decision process, or auditing the user's entire decision system, asking which is wanted unless the request already makes it obvious. For a single question it runs a five-layer check in order - whether key words like good or safe are operationally defined, which unstated assumptions the question depends on, whether entry, invalidation, sizing and horizon rely on compatible judgments, which premises are verified versus merely opinions, and whether scope, evidence, invalidation, risk budget, horizon and an explicit human choice are all present - stopping as soon as the original question dissolves and stating exactly why.
It classifies the result as well-formed (structurally answerable, though answering the investment itself stays out of scope), underspecified, or another category, and reads additional reference files on strategy families or historical inconsistency patterns only when the user's situation actually calls for them.
When your agent uses it
- Checking whether an investment strategy's rules are internally consistent
- Finding why your own trading execution keeps drifting from the plan
- Auditing a whole personal investment decision system for gaps
Example prompts
- “Diagnose whether my stop-loss rule actually matches my entry logic.”
- “Why does my execution always drift from my stated strategy?”
- “Audit my whole investment decision system for structural conflicts.”
Workflow steps
2 steps, taken from the first numbered list in SKILL.md.
- Question diagnosis — examine one investment question or decision process.
- Structure checkup — audit the user's whole decision system.
What it can do on your machine
Read from SKILL.md and the folder at commit fce3769. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Investment Strategy Structure Diagnostician loads about 2.2k tokens when it runs, and up to ~4k if it reads all its reference files. Until then it costs about 96 tokens; SKILL.md has 1,004 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,004 words (~2,170 tokens).
“Act as a strategy-structure diagnostician. Diagnose whether the user's stated strategy can be expressed, falsified, risk-budgeted, executed, and audited. Do not judge whether the strategy will make money.”
