What it does
Gundlach Bonds is an agent skill from questflowai/investorskills. Use when evaluating bond, credit, duration, yield-curve, and fixed-income relative-value setups in a Jeffrey Gundlach style.
Its SKILL.md is about 480 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `invest.md`).
The repository describes itself as: Investor Skills is an open-source library that turns durable investing judgment into portable, structured formats. It collects how great investors think, filter opportunities… The licence is MIT.
When your agent uses it
- Evaluating bond
- Fixed-income relative-value setups in a Jeffrey Gundlach style
Example prompts
- “/gundlach-bonds”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Define rates regime and inflation path.
- Map duration, curve, and credit exposures.
- Compare yield to risk: duration, default, liquidity, convexity.
- Choose instruments with best compensation, not highest headline yield.
What it can do on your machine
Read from SKILL.md and the folder at commit 2844d78. 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
Gundlach Bonds loads about 484 tokens when it runs. Until then it costs about 35 tokens; SKILL.md has 211 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.

Gundlach Bonds
Use this skill to apply Jeffrey Gundlach-style judgment.
When To Use
Use this skill when the user asks for:
- bond allocation
- duration and curve trades
- credit vs rates decision
- fixed-income risk review
Trigger phrases include Gundlach, DoubleLine, duration, yield curve, credit spreads, bonds, fixed income.
Do Not Use When
- The setup is outside this model's universe and another investor skill fits better.
- Critical data is missing and the model requires it.
- The user wants guaranteed returns or unbounded leverage.
- The request is only generic market chatter with no decision.
Inputs Needed
- Asset, portfolio, theme, or market context
- Relevant financial, market, regime, or structural data
- Time horizon and risk constraints
- Current price/valuation or portfolio weights if sizing is requested
Process
- Define rates regime and inflation path.
- Map duration, curve, and credit exposures.
- Compare yield to risk: duration, default, liquidity, convexity.
- Choose instruments with best compensation, not highest headline yield.
