flightline

flightline is a skill for Claude Code from IamK77/Skill. It costs 37 tokens per session (1,211 once invoked), scanned A, original, Apache-2.0.

A set of engineering practices that makes basic quality checks automatic across version control, branching, code style, review, continuous integration and delivery, dependencies, and builds. Continuous integration and delivery automatically check and move code through the development and release process.

In plain words
What is it for?
Use it to establish or improve a project's day-to-day development process. It helps set up shared rules, code review, automated pipelines, dependency management, and build checks.
Why use it?
It prevents quality from depending only on each contributor remembering the right steps. Automated checks can catch problems such as unreviewed code, exposed secrets, inconsistent style, and unsafe dependency or build changes.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

flightline scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 97 lines — stays where its author put it; the contents beside it link to each section on GitHub.

flightline

Prepare a reviewable, reproducible change and delivery pipeline. Use for repository hygiene, CI work, or release preparation without implying permission to commit, push, or deploy.

Inputs

Change scope; repository conventions; current branch and worktree; expected lint/build/test commands; requested delivery boundary.

Run record

Use checklist 0.5 or newer for this SOP. Reading or reloading the skill must not reset work. For a new task, run checklist init "${CLAUDE_SKILL_DIR}" --new --path "/absolute/project"; retain its returned ID as RUN. For existing work, use checklist resume "$RUN", then checklist show --run "$RUN". Outside Claude, replace the skill-directory variable with this directory’s actual path.

Commands below record work after it is done. Replace evidence placeholders with concise artifact locations and observations. Manual confirmations are not independent proof; a sensor pass covers only the command and inputs it observed. verify does not close a stage; advance checks that its required readings are fulfilled. Use report --run "$RUN" for the retained history.

Before starting, inspect the project and bind LINT_CMD to its real trusted command with --var 'LINT_CMD=<actual command>'. Do not use an echo/no-op to produce a green result. checklist resume "$RUN" --var 'LINT_CMD=<new command>' changes the binding and invalidates earlier readings; commands and output are stored locally, so do not bind secrets.

Procedure

scope

Inspect the current worktree and separate the requested change from unrelated edits. Read the repository contribution and dependency conventions; identify the intended review or delivery boundary.

Record these artifacts after doing the work:

  • Branch, existing changes, and ownership boundaries are recorded. checklist check scope worktree --run "$RUN" --evidence "<artifact and observation>"
  • Required checks and the requested delivery boundary are known. checklist check scope contract --run "$RUN" --evidence "<artifact and observation>"

Files

What ships with it

10 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
