What it does

Harness Lint is an agent skill from CorrectRoadH/OpenTickly. Use when working in this repository after receiving recurring coding feedback, adding or reviewing durable lint guardrails from AGENTS.md, updating rules/.md, or finishing changes that should be checked by harness-lint.

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, covering Linting and formatting and Agent instruction files. The repository describes itself as: Self-hosted, Toggl-compatible time tracker. The licence is AGPL-3.0.

When your agent uses it

  • Working in this repository after receiving recurring coding feedback
  • Reviewing durable lint guardrails from AGENTS.md
  • Updating rules/.md
  • Finishing changes that should be checked by harness-lint

Example prompts

  • “/harness-lint”

Workflow steps

7 steps, taken from the first numbered list in SKILL.md.

  1. Run commands from the repository root.
  2. Use harness-lint from PATH. If it is missing on this machine and /Users/ctrdh/Code/harness-lint/target/debug/harness-lint exists, that…
  3. When the user gives a recurring coding preference, create or update a rule under rules/ instead of only changing the current code.
  4. Rules must use GritQL for executable checks. If the preference needs cross-file state, changed-file path ownership, human review, or…
  5. Do not delete, disable, or weaken rules to make a task pass unless the user explicitly asks for that.
  6. Before finishing code changes, run harness-lint check --changed and report any diagnostics.
  7. Use harness-lint rule list after changing rule configuration. It prints Markdown tables; do not pass --json to rule list.

What it can do on your machine

Read from SKILL.md and the folder at commit 5ffd0a0. 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

Harness Lint loads about 396 tokens when it runs. Until then it costs about 58 tokens; SKILL.md has 188 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~58
When it runs · the whole SKILL.md, loaded when a task matches
~396

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.

Harness Lint

Use harness-lint to turn recurring repository feedback into executable or reviewable rules.

Workflow

  1. Run commands from the repository root.
  2. Use harness-lint from PATH. If it is missing on this machine and /Users/ctrdh/Code/harness-lint/target/debug/harness-lint exists, that local debug binary is an acceptable fallback.
  3. When the user gives a recurring coding preference, create or update a rule under rules/ instead of only changing the current code.
  4. Rules must use GritQL for executable checks. If the preference needs cross-file state, changed-file path ownership, human review, or richer semantics than a stable GritQL pattern can provide, keep it as status: draft.
  5. Do not delete, disable, or weaken rules to make a task pass unless the user explicitly asks for that.
  6. Before finishing code changes, run harness-lint check --changed and report any diagnostics.
  7. Use harness-lint rule list after changing rule configuration. It prints Markdown tables; do not pass --json to rule list.

Project Sources

  • AGENTS.md is the source for durable repository workflow and coding constraints.
  • harness.toml configures local rules and external packs.
  • harness.lock records installed pack revisions.
  • .harness/ is generated cache and must stay uncommitted.
