What it does
Packet Validation is an agent skill from pellegre/libcrafter. Add or run deterministic libcrafter packet behavior validation through oracle specs, reference backends, offline checks, pcap checks, probe plans, and artifacts.
Its SKILL.md is about 420 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 Development. It works with Rust. The repository describes itself as: A Rust library for constructing, sending, capturing, and decoding network packets. The licence is MIT.
When your agent uses it
- Development work in your project
Example prompts
- “/packet-validation”
Workflow steps
8 steps, taken from the first numbered list in SKILL.md.
- Update the relevant tools/oracle/specs/ contract first.
- Keep independent implementation logic inside
- Update backend materialization and normalization for the new case.
- Run strict spec validation and focused offline validation.
- Run pcap validation when framing, link types, capture files, or persisted
- Generate the relevant deterministic probe plan when peer behavior matters.
- Run Rust unit and adapter tests for any bounded executor changes.
- Record intentional mismatches and unsupported behavior in tracked specs or
What it can do on your machine
Read from SKILL.md and the folder at commit f9ef000. 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
Shell commands in SKILL.md call:
cargo
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
Packet Validation loads about 418 tokens when it runs. Until then it costs about 45 tokens; SKILL.md has 148 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.

- description
- Add or run deterministic libcrafter packet behavior validation through oracle specs, reference backends, offline checks, pcap checks, probe plans, and artifacts.
Packet validation
Use this skill whenever packet construction, decode, checksums, framing, options, malformed behavior, or response matching changes.
Required workflow
- Update the relevant
tools/oracle/specs/contract first. - Keep independent implementation logic inside
tools/oracle/engine/backends/. - Update backend materialization and normalization for the new case.
- Run strict spec validation and focused offline validation.
- Run pcap validation when framing, link types, capture files, or persisted bytes are affected.
- Generate the relevant deterministic probe plan when peer behavior matters.
- Run Rust unit and adapter tests for any bounded executor changes.
- Record intentional mismatches and unsupported behavior in tracked specs or nearby documentation.
Typical commands:
tools/oracle/run specs validate --strict
tools/oracle/run offline --profile PROFILE --seed SEED --count COUNT
tools/oracle/run pcap --profile PROFILE --seed SEED --count COUNT
tools/probe/run --profile PROFILE --seed SEED --count COUNT --out target/probe/plan
cargo test -p probe-adaptersThis repository does not own machine selection, credentials, remote access, machine lifecycle, peer preparation, hardware leases, or execution topology. When hardware-backed qualification is necessary, use only operator-supplied untracked tooling, after the deterministic gate passes, and preserve evidence for the exact candidate revision.

When should I use Packet Validation?
Packet Validation fits situations like: development work in your project.
How do I install Packet Validation in Claude Code?
Run `npx skills add pellegre/libcrafter --skill packet-validation -a claude-code`. Or copy the skill folder (.agents/skills/packet-validation in pellegre/libcrafter) into .claude/skills/packet-validation in your project. Claude Code loads it when a task matches its description.

Can I use Packet Validation in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add pellegre/libcrafter --skill packet-validation -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/packet-validation, .gemini/skills/packet-validation, .github/skills/packet-validation and .opencode/skills/packet-validation in your project.
What does Packet Validation need to run?
Going by SKILL.md and its folder, Packet Validation needs the command-line tools its instructions call (cargo).
Does Packet Validation access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
