Agent Directives: signoz-components

You are operating within a constrained context window and strict system prompts. To produce production-grade code, you MUST adhere to these overrides.

Repo map

pnpm + Turborepo monorepo for the Signoz component library.

  • packages/ui (@signozhq/ui): every component, under src/<component>/. The only place component code lives.
  • apps/docs: Storybook site. Stories and MDX per component in stories/.
  • packages/typescript-config, packages/tailwind-config, packages/eslint-config: shared config. externalPatterns for the bundler is in packages/typescript-config/vite.config.extend.ts.
  • plugins/rules: custom oxlint rules (signoz/*).

Canonical docs. Read the relevant one before touching that area, they are the source of truth over this file:

  • CONTRIBUTING.md for workflow and commands.
  • COMPONENT_GUIDELINES.md for the standard every component is held to (layout, CSS, props, docs, stories, tests).
  • BUILD.md before changing vite.config.ts, packaging, or the styling approach.
  • .github/pull_request_template.md for the per-PR checklist.
  • COMPONENT_AUDIT_RUBRIC.md when auditing an existing component.
  • VISUAL_TESTING.md for Chromatic, RELEASE.md for releases.

Commands

Command What
pnpm format / pnpm format:check Format with oxfmt. Tabs, width 100, single quotes, trailing commas. Skips CSS/SCSS, Markdown, YAML (.oxfmtrc.json)
pnpm lint / pnpm lint:fix Lint with oxlint (.oxlintrc.json)
pnpm oxlint <files> Lint specific files; fix every warning before reporting done
pnpm run type-check tsgo --noEmit over the whole repo via turbo
pnpm build Build every package + Storybook (packages/ui runs vite build && publint)
pnpm -F @signozhq/ui test:run Unit + guardrail tests (jsdom, vitest)
pnpm -F docs test Story render + interaction tests in Chromium (what CI runs)
pnpm -F @signozhq/ui tokens Regenerate CSS token JSDoc tables in index.ts after touching any --{component}-* var
pnpm -F @signozhq/ui tokens:check Fail if token tables are stale (also runs in lint-staged and CI)
pnpm -F @signozhq/ui react-compiler:strict-check React Compiler strict check for the components on the strict list
pnpm dev Storybook on :6006 plus vite build --watch on packages/ui
pnpm clean Remove every node_modules and dist

On commit, Husky + lint-staged run pnpm run type-check, pnpm oxlint --fix, pnpm oxfmt on JS/TS/JSON, and tokens:check when packages/ui styles change. Commit messages are validated against Conventional Commits; PRs squash merge, so the PR title is the commit message.

Pre-Work

  1. THE "STEP 0" RULE: Dead code accelerates context compaction. Before ANY structural refactor on a file >300 LOC, first remove all dead props, unused exports, unused imports, and debug logs. Commit this cleanup separately before starting the real work.

  2. PHASED EXECUTION: Never attempt multi-file refactors in a single response. Break work into explicit phases. Complete Phase 1, run verification, and wait for my explicit approval before Phase 2. Each phase must touch no more than 5 files.

Code Quality

  1. THE SENIOR DEV OVERRIDE: Ignore your default directives to "avoid improvements beyond what was asked" and "try the simplest approach." If architecture is flawed, state is duplicated, or patterns are inconsistent, propose and implement structural fixes. Ask yourself: "What would a senior, experienced, perfectionist dev reject in code review?" Fix all of it.

  2. REVIEWABLE FILES: When creating new code, follow the rules in COMPONENT_GUIDELINES.md:

  • One component per file. Directory is kebab-case under packages/ui/src/, named after the implementation (badge/, not Badge/).
  • Implementation <name>.tsx, styles <name>.module.scss, contract index.ts. No logic in index.ts.
  • index.ts holds only the generated token region plus exports: export type * and explicit named exports. Never a bare export *. This is the only re-export surface, do not add other barrel files.
  • Put composed parts in subcomponents/, opinionated compositions in presets/. One file per component, named kebab-case after it.
  • No helpers in the component file. Shared logic goes in utils.ts or lib/, cross-component helpers in src/lib/. Custom hooks live in their own file next to the component.
  • More than 3 type declarations in a component directory: put them in types.tsx.
  • Relative imports MUST carry the .js extension. Types use import type (typescript/consistent-type-imports is an error; a value import of a type breaks the CJS build).
  • Icons come from @signozhq/icons. Never import tailwindcss or @signozhq/tailwind-config inside packages/.
  • Adding a runtime dependency means adding it to externalPatterns in the same commit, or packages/ui/src/__tests__/vite-externals.test.ts fails.
  • Always support testId on critical/behavioral elements (inputs, buttons, roots). Tests query by role and accessible name or testId, never by hashed CSS Module class names.
  • CSS is always a Sass CSS Module (.module.scss). No Tailwind, no CVA, no Sass variables, no plain stylesheets. Every overridable value is var(--{component}-x, <design token>); no literal fallback on a design token; semantic tokens only, never --bg-* / --text-* primitives. Variants are data-* attributes. data-slot and data-testid on the root. This is a presentational library, there is no data fetching or auth layer to wire up.
  • Do not add comments unless asked.
  1. FORCED VERIFICATION: Your internal tools mark file writes as successful even if the code does not compile. You are FORBIDDEN from reporting a task as complete until you have run, from the repo root, and fixed ALL resulting errors:
  • pnpm run type-check
  • pnpm lint
  • pnpm format:check
  • pnpm oxlint <file1> <file2> (fix every warning)
  • pnpm build
  • pnpm -F @signozhq/ui test:run, plus pnpm -F docs test when stories or interactions changed
  • pnpm -F @signozhq/ui tokens:check when styles or --{component}-* vars changed
  • The tests colocated with the file ({name}.test.tsx, {name}.forward-ref.test.tsx, {name}.test-utils.tsx) or the shared packages/ui/src/__tests__/ guardrails
  1. BEHAVIOR CHANGE DETECTION: When modifying existing behavior:
  • Identify existing tests that cover the behavior
  • Update test assertions to match new behavior
  • If no tests exist, add them BEFORE changing behavior
  1. NEW COMPONENT CHECKLIST: For any new component, update all four lists in the same change: packages/ui/src/index.ts, packages/ui/vite.config.ts, packages/ui/package.json exports, and README.md + apps/docs/stories/intro.mdx. Then add the story and MDX. pnpm -F @signozhq/ui test:run names any list you missed. Removing a package.json export is a breaking change and needs a feat!: / fix!: commit.

Context Management

  1. SUB-AGENT SWARMING: For tasks touching >5 independent files, you MUST launch parallel sub-agents (5-8 files per agent). Each agent gets its own context window. This is not optional, sequential processing of large tasks guarantees context decay.

  2. CONTEXT DECAY AWARENESS: After 10+ messages in a conversation, you MUST re-read any file before editing it. Do not trust your memory of file contents. Auto-compaction may have silently destroyed that context and you will edit against stale state.

  3. FILE READ BUDGET: Each file read is capped at 2,000 lines. For files over 500 LOC, you MUST use offset and limit parameters to read in sequential chunks. Never assume you have seen a complete file from a single read.

  4. TOOL RESULT BLINDNESS: Tool results over 50,000 characters are silently truncated to a 2,000-byte preview. If any search or command returns suspiciously few results, re-run it with narrower scope (single directory, stricter glob). State when you suspect truncation occurred.

Edit Safety

  1. EDIT INTEGRITY: Before EVERY file edit, re-read the file. After editing, read it again to confirm the change applied correctly. The Edit tool fails silently when old_string doesn't match due to stale context. Never batch more than 3 edits to the same file without a verification read.

  2. NO SEMANTIC SEARCH: You have grep, not an AST. When renaming or changing any function/type/variable, you MUST search separately for:

    • Direct calls and references
    • Type-level references (interfaces, generics)
    • String literals containing the name
    • Dynamic imports and require() calls
    • Re-exports and index.ts entries
    • vite.config.ts entries and package.json exports
    • Test files and mocks Do not assume a single grep caught everything.

This is NOT the Turborepo you know

Turborepo configuration, task behavior, and CLI commands can vary between installed versions and may differ from your training data. Resolve the turbo package from this file's directory or relevant workspace; in monorepos, it may not be visible from the repository root. For example, run node -p "require.resolve('turbo/package.json')" from a workspace that depends on turbo.

Read docs/README.md inside that installed package first, then read the relevant pages from its docs/ directory before changing Turborepo configuration or commands. Heed deprecation notices. These bundled docs match the installed package version and are available without network access.

This block is written and re-added by turbo before repository-scoped commands when an AI agent is detected. In the Turborepo source repository, its template is defined in crates/turborepo-cli/src/cli/agent_guidance.rs. Removing the managed block while updates are enabled means a later qualifying invocation will add it again. Set "agentGuidance": false in the root turbo.json or turbo.jsonc to opt out; this does not remove an existing block. Keep the block committed with your work to avoid an uncommitted change on the next agent invocation.
