coverage-baseline

coverage-baseline is a skill for Claude Code from bdfinst/agentic-dev-team. It costs 84 tokens per session (4,996 once invoked), scanned A, original, MIT.

A worker that finds the project's coverage tool, runs it, and records the starting line and branch coverage. Coverage measures which parts of the code tests execute.

In plain words
What is it for?
Recording a test-coverage baseline before a test-improvement workflow begins.
Why use it?
It establishes a measured starting point so later test work can be compared against the same baseline.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

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

coverage-baseline 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 — 336 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Coverage Baseline

Role: worker. Captures the true baseline coverage of the repo after cannot-fail tests have been disabled so the floor isn't inflated by tautologies.

You have been invoked with the /coverage-baseline command.

Parse Arguments

Arguments: $ARGUMENTS

  • Positional: <repo-path>.
  • --parent <issue-url> — parent issue URL on the resolved tracker (or empty for local-files mode).
  • --repo-slug <slug> — namespace under .claude/memory/<workflow>/.
  • --workflow <name> — the workflow namespace under .claude/memory/. Defaults to test-improve. Orchestrators pass their own namespace (e.g. /test-improve passes test-improve for its Phase-2 baseline).

If <repo-path> is absent, ask the operator.

Steps

1. Detect the coverage tool

Read the build manifest at the repo root and pick the appropriate command:

Manifest Default coverage command
package.json (JS/TS) npm test -- --coverage (or pnpm test --coverage, yarn test --coverage) — or, when a workspace signal is present (a root workspaces field, pnpm-workspace.yaml, or lerna.json), multi-project discovery (see Step 1a)
pyproject.toml / setup.py pytest --cov=. --cov-report=json
pom.xml mvn test jacoco:report — or, when the root pom.xml declares <modules>, multi-project discovery (see Step 1a)
build.gradle* ./gradlew test jacocoTestReport — or, when settings.gradle/settings.gradle.kts declares include(...), multi-project discovery (see Step 1a)
*.csproj dotnet test /p:CollectCoverage=true /p:CoverletOutputFormat=json — or, when a .sln is present at the repo root, multi-project discovery (see Step 1a)
Cargo.toml cargo llvm-cov --json
go.mod go test -coverprofile=coverage.out ./... + go tool cover -func=coverage.out

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.
