dev-guide-contributing

dev-guide-contributing is a skill for Claude Code, Codex from Lingtai-AI/lingtai. It costs 51 tokens per session (4,095 once invoked), scanned A, original, Apache-2.0.

Contribution instructions for LingTai, covering worktrees, issues, pull requests, builds, tests, translations, file-based communication, and project anatomy documents. A worktree is a separate working copy of a Git repository.

In plain words
What is it for?
Use them when preparing a LingTai change, managing worktrees, splitting daemon work, updating translations, running builds or tests, changing skills, or preparing a pull request.
Why use it?
They spell out project rules that are easy to miss, such as updating anatomy documents when code moves and changing all required language files for new translated text. This reduces review failures and inconsistent changes.

    Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.
    Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.

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

dev-guide-contributing 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 9d 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.

Contributing to LingTai

Nested lingtai-dev-guide reference. Read this after the top-level router sends you here.

General principles

  1. Filesystem-only IPC. TUI, portal, and kernel communicate exclusively through files. Need cross-process communication? Write a file and let the other side poll.
  2. Anatomy updates are part of the code change. If your change moves, renames, splits, merges, or deletes anything cited by an ANATOMY.md, update the anatomy in the same commit (see "Anatomy maintenance" below).
  3. Three-locale rule. A new i18n key means updating en.json, zh.json, and wen.json in both tui/i18n/ and (where applicable) portal/i18n/. Missing translations render as the raw key — they don't fall back.
  4. Binary naming. The TUI binary is lingtai-tui, never lingtai. lingtai is the Python agent CLI inside the runtime venv.
  5. Every non-trivial PR gets a self-contained HTML explainer, local-only by default. Requirements, naming, sections, the commit-vs-local rule, and the waiver exception live in reference/pr-review-deliverables/SKILL.md §3 — follow it rather than a summary here.
  6. Prefer one honest sandbox acceptance when it exercises the real end-to-end path. Keep only minimal syntax/smoke checks for obvious breakage; open the reviewable PR promptly and continue broader validation after the PR when needed, rather than building a broad pytest or synthetic matrix.
  7. Every test must earn its maintenance cost by protecting a distinct failure invariant. Inventory existing coverage before adding cases. When one mechanism needs multiple inputs, prefer table-driven or parameterized cases and shared setup over one pytest per narrative example. Do not inflate a PR with exhaustive assertion prose, and do not delete non-overlapping old tests merely to make the diff smaller.

Orchestrator + daemons (how the work happens)

The operating discipline for any non-trivial LingTai contribution — TUI, portal, kernel, addons, or skills.

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.
