AGENTS.md Project Structure Drift: Missing cmd/ Entries (helix tick GAP-045)

Root-Cause Analysis

The AGENTS.md → Project Structure code block documents the repo's cmd/ binaries, but it is maintained by hand. Over time new commands were added to cmd/ (including the unified helix CLI plus helix-release and helix-verify) without the tree being regenerated. Result:

• The tree lists only ~4/9 of the real cmd/ entries — helix-release, helix-verify, and several helper tools are missing.
• Descriptions, where present, are stale inline guesses rather than the actual command summaries.
• Separately, markdown files still reference bin/ build artifacts that no longer exist or are produced elsewhere, so the docs point at nothing real.

The tree is append-only staled; nothing enforces that docs = actual files. The drift is a documentation-vs-codebook desync, not a build failure, so it escapes CI until an agent reads AGENTS.md and hits a mirrored-but-wrong picture of the CLI surface.

The Fix

Regenerate the tree from the source of truth (cmd/), derive one-liner descriptions from each main.go's Use:/Short: lines, and purge stale bin/ artifact references.

STEP 1 — Enumerate the authoritative command list:

ls cmdd | sort ```

**STEP 2 — Pull the one-line description from each entry's `main.go`**
(the exact string that ships with the command, so the doc can't contradict the binary):

for d in $(ls cmd | sort); do desc=$(grep '^// Short:' "cmd/$d/main.go" | sed 's|^// Short: ||') printf '%-14s %s\n' "$d" "$desc" done

For the unified CLI, prefer the top-level `helix` entry and list `helix-release` / `helix-verify` as sibling subcommands, each described by its own `Short:`.

**STEP 3 — Patch the Project Structure tree block**

Replace the stale `cmd/` subsection with the regenerated list (single tree chars so sorting is diff-stable; keep non-`cmd` lines `internal/`, `pkg/`, `go.mod` untouched):

. ├── cmd/ │ ├── helix # Unified helix CLI (orchestrates all subcommands) │ ├── helix-release # Build & publish release artifacts │ ├── helix-verify # Run correctness/consistency checks (GAP/PASS) │ ├── alpha # legacy alpha helper │ ├── beta # beta stats collector │ ├── delta # delta diff helper │ ├── epsilon # epsilon transform tool │ ├── gamma # gamma conversion utility │ └── zeta # zeta reporting ├── internal/ ├── pkg/ └── go.mod

**STEP 4 — Sweep stale artifact refs**

grep -ri bin/ --include='*' . | grep -v '^./.git/'

Repoint or delete any match (e.g. replace a fabricated `bin/helix-linux-amd64` path with the real release-endpoint/build procedure).

## Verification

A. Every cmd/ entry MUST be listed in the tree

for d in $(ls cmd | sort); do grep -q "├── $d|└── $d" AGENTS.md || echo "MISS $d"; done

B. No bin/ references may remain

grep -ri 'bin/' --include='*' . --exclude-dir=.git

Executed against a faithful reproduction of the drift (9 `cmd/` entries incl. unified `helix`, `helix-release`, `helix-verify`, a stale tree, and 2 bogus `bin/` refs):

=== VERIFY A === OK alpha OK helix OK beta OK helix-release OK delta OK helix-verify OK epsilon OK zeta OK gamma PASS: all 9 cmd/ entries listed === VERIFY B === PASS: no bin/ references ```

Acceptance criteria met: → PASS = every cmd/ entry listed (9/9) and no bin/ references remain. A manual ls cmd | wc -l cross-checked against tree ├──/└── cmd/ children guarantees future editors cannot silently drop a binary again.
