  • Works in 4 steps: Extract story IDs → Search for story tags in code → Build the matrix → …

  • SKILL.md covers Pre-flight and Process
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Trace Requirement is an agent skill from danielvm-git/bigpowers. Link story IDs from specs/release-plan.yaml + epic capsule directories to the implementing code and tests. Produces specs/TRACEABILITYLATEST.md. Use when you want to verify coverage of a release plan, audit which stories are implemented, or find "dark" stories with no code.

Its SKILL.md is about 630 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 Product & Project Management, covering Feature launches and release readiness. The repository describes itself as: Agent skills synthesizing years of software engineering discipline into a prescriptive methodology for solo developers. The licence is MIT.

When your agent uses it

  • You want to verify coverage of a release plan
  • Audit which stories are implemented
  • Find dark stories with no code

Example prompts

  • “/trace-requirement”

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. Extract story IDs
  2. Search for story tags in code
  3. Build the matrix
  4. Write specs/TRACEABILITY_LATEST.md

What it can do on your machine

Read from SKILL.md and the folder at commit 812d57a. 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

Trace Requirement loads about 625 tokens when it runs. Until then it costs about 73 tokens; SKILL.md has 195 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~73
When it runs · the whole SKILL.md, loaded when a task matches
~625

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.

Trace Requirement

Build a traceability matrix from specs/release-plan.yaml + epic capsule directories to implementing code and tests. Surfaces gaps in both directions: stories with no code, and code with no story.

Pre-flight

HARD GATE — specs/release-plan.yaml + epic capsule directories must exist. If it doesn't, run plan-release first.

→ verify: test -f specs/release-plan.yaml && test -d specs/epics

Read specs/release-plan.yaml + epic capsule directories fully before proceeding.

Process

1. Extract story IDs

From release-plan.yaml, collect all story IDs (e.g. 1.1, 1.2, 2.1).

→ verify: grep -rho 'e[0-9]\+s[0-9]\+' specs/release-plan.yaml specs/epics/*/epic.yaml 2>/dev/null | sort -u | head -1 | grep -q .

2. Search for story tags in code

Look for // story: X.Y or # story: X.Y comments in source files and tests:

grep -rn "story: " . --include="*.ts" --include="*.js" --include="*.py" --include="*.sh" | grep -v node_modules

→ verify: [ "$(grep -rl "story: " . --include="*.ts" --include="*.sh" --include="*.py" 2>/dev/null | wc -l | tr -d " ")" -gt 0 ]

3. Build the matrix

For each story ID:

  • Implemented: list files that contain // story: X.Y
  • Tested: list test files that contain // story: X.Y
  • Dark: story has no tag in any file — flag as unimplemented

For each tagged file with no matching story ID in release-plan.yaml:

  • Orphan: code exists but story was removed or never planned — flag for cleanup
4. Write specs/TRACEABILITY_LATEST.md
## Story Coverage

| Story | Title              | Files | Tests | Status    |
|-------|--------------------|-------|-------|-----------|
| 1.1   | [title]            | 2     | 1     | Covered   |
| 1.2   | [title]            | 0     | 0     | Dark      |

## Orphan Code (no story tag)
- [file]: contains untagged implementation

## Gaps (dark stories)
- Story 1.2: no implementation found → run plan-work

## Coverage summary
Stories: [X] covered / [Y] dark / [Z] total

→ verify: grep -c "Covered\|Dark" specs/TRACEABILITY_LATEST.md

Suggest plan-work for each dark story found.
