What it does
Ijfw Preflight is an agent skill from FerroxLabs/ijfw. Run the IJFW preflight pipeline (11 gates, fail-fast). Trigger: 'ijfw preflight', 'run preflight', 'check before ship', 'preflight gates', 'validate before release'.
Its SKILL.md is about 400 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 npm. The repository describes itself as: IJFW — It Just Fcking Works. Ferrox Labs' local-first infrastructure for AI coding agents: shared memory, smart routing, multi-AI cross-audits, disciplined workflow. The licence is MIT.
When your agent uses it
- Development work in your project
Example prompts
- “ijfw preflight”
- “run preflight”
- “check before ship”
- “/ijfw-preflight”
Workflow steps
11 steps, taken from the first numbered list in SKILL.md.
- shellcheck -- shell script correctness
- oxlint -- fast JS/TS linting
- eslint-security -- high-signal JS security rules
- psscriptanalyzer -- PowerShell scripts, with static fallback when pwsh is absent
- publint -- package.json publish hygiene
- gitleaks -- secret / credential scan
- audit-ci -- npm dependency vulnerability check
- knip -- dead code and unused exports
- license-check -- dependency license compatibility
- pack-smoke -- npm pack roundtrip + ijfw --help assert
- upgrade-smoke -- upgrade from floor version, assert settings key survives
What it can do on your machine
Read from SKILL.md and the folder at commit eda62f3. 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:
npmgit
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npm and 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
Ijfw Preflight loads about 395 tokens when it runs. Until then it costs about 45 tokens; SKILL.md has 178 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
- Run the IJFW preflight pipeline (11 gates, fail-fast). Trigger: 'ijfw preflight', 'run preflight', 'check before ship', 'preflight gates', 'validate before release'.
IJFW Preflight
Runs 11 deterministic quality gates locally. Ordered fast-to-slow, fail-fast on blockers. Returns exit 0 on clean, exit 1 on findings.
Usage
ijfw preflightWhat it checks
- shellcheck -- shell script correctness
- oxlint -- fast JS/TS linting
- eslint-security -- high-signal JS security rules
- psscriptanalyzer -- PowerShell scripts, with static fallback when pwsh is absent
- publint -- package.json publish hygiene
- gitleaks -- secret / credential scan
- audit-ci -- npm dependency vulnerability check
- knip -- dead code and unused exports
- license-check -- dependency license compatibility
- pack-smoke --
npm packroundtrip +ijfw --helpassert - upgrade-smoke -- upgrade from floor version, assert settings key survives
Behavior
- Each gate degrades gracefully to "skipped: tool not installed" when its CLI is absent (except blockers, which print actionable install hints).
- All output uses positive framing. No "failed" headers -- findings are reported as "surfaced N points".
- Runs under 90s on M-series laptop with warm caches.
- Pinned tool versions tracked in
.ijfw/preflight-versions.json.
When to run
- Before every
git tag/ release. - After any change to shell scripts, package.json, or dependency list.
- In CI (
.github/workflows/ci.ymlrunsijfw preflighton every push).
