What it does
Calimero Security Fix is an agent skill from calimero-network/core. Fixes a security finding in calimero-network/core - reproduce it through the real entry point, commit a failing test first, add the limit or gate in the shared function every caller goes through, review for bypasses, and open a neutral PR. Use when asked to fix a vulnerability, an audit finding, a DoS or an authorization gap in core.
Its SKILL.md is about 610 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Testing & QA, covering Test-driven development and Audit readiness. The repository describes itself as: Calimero - Peer-to-peer application platform with local-first governance, CRDT state sync, and WASM execution.
When your agent uses it
- Asked to fix a vulnerability
- An audit finding
- An authorization gap in core
Example prompts
- “Use the calimero-security-fix skill to fix a security finding in calimero-network/core - reproduce it through the real entry point, commit a failing…”
- “/calimero-security-fix”
Workflow steps
9 steps, taken from the first numbered list in SKILL.md.
- Reproduce through the real entry point, the way an attacker would: a gossip message, a sync stream, an HTTP request or a guest call, not a…
- Commit the test first and watch it fail on master for the stated reason, not for a setup error.
- Add the limit constant for any unbounded input, named and declared with the other constants of its file.
- Fix in the shared function that every caller goes through.
- Run two review rounds with fresh agents, each looking for bypasses, regressions for honest users (a member who left and rejoined, a…
- Rebase onto current master and rerun the gates right before opening: ./scripts/check-like-ci.py, which includes the feature-gated test…
- Use a neutral title and body: say what the code now does, not how to exploit what it did, and answer the template's Trust boundary block.
- Check open PRs for the same files and for a schema version number someone else has already claimed.
- Pair SDK changes with the matching mero-js PR, named in the body as sdk-ref: .
What it can do on your machine
Read from SKILL.md and the folder at commit 64f9209. 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.
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
Calimero Security Fix loads about 614 tokens when it runs. Until then it costs about 89 tokens; SKILL.md has 338 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 338 words (~614 tokens).
“The rules a fix must satisfy are in CODING_STANDARDS.md ("Security: trust boundaries"). This skill is the workflow; it does not repeat them.”
