What it does
Fragility Common is an agent skill from BuilderIO/agent-native. Shared library and file contracts for the fragility skills (system-history, bug-trace, refactor-plan, jira-refactor-findings, identify-fragile-systems, investigate-bug). Read when changing how those skills exchange data. Not a workflow on its own.
Its SKILL.md is about 620 tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files (for example `config.json`, `lib/artifacts.ts` and `lib/cli.ts`).
It sits in Development, covering Refactoring. It works with Jira and Git. The repository describes itself as: A framework for building agentic apps.
When your agent uses it
- Tasks that involve Refactoring
Example prompts
- “/fragility-common”
Requirements
- Node.js
What it can do on your machine
Read from SKILL.md and the folder at commit 1c2de07. 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
Ships script files (TypeScript), which the agent can run.
Shell commands in SKILL.md call:
git
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.
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
Fragility Common loads about 618 tokens when it runs. Until then it costs about 66 tokens; SKILL.md has 239 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
Without a licence we can't republish the file, so here is its outline and opening line. It has 239 words (~618 tokens).
“No workflow lives here. This folder holds code and contracts shared by the fragility skills, so each skill can change on its own without breaking the others.”
