The agent acts as a tech lead — reads KB, Requirements, and codebase, proposes technical solutions, and builds the spec collaboratively with the user. Writes to SPEC.md in the feature folder. State machine: INITIALIZE → CONTINUE → REVIEW → DONE (SPIKE / BLOCKED are loopback states that return to CONTINUE). allowed-tools: Read, Glob, Grep, Terminal, Write, Edit argument-hint: "work-001/feature-001 (required) [--reset] clear technical spec for this feature"

Technical Specification — Conversational Refinement

Specify the technical implementation of a single feature through conversational refinement with the user.

The agent is a tech lead, not an interviewer. It proposes concrete solutions grounded in the existing architecture. The user validates, redirects, or deepens the discussion.

One feature at a time. The feature path is a required argument.

The Loop:

Every section follows the same cycle:

1. PROPOSE  → agent proposes (grounded in KB, codebase, SPEC)
2. DISCUSS  → user and agent refine together
3. WRITE    → save what was agreed to SPEC.md
4. REVIEW   → grade what was written against KB/codebase reality
             → pass? next section. fail? back to 1.

Re-run = enter at step 4 with existing content.

Workspace:

.aid/
  knowledge/               ← shared KB
  work-NNN-{name}/
    STATE.md               ← process (§ Features State table, § Cross-phase Q&A)
    REQUIREMENTS.md
    features/
      feature-NNN-{name}/
        SPEC.md            ← product (requirements + technical specification)

⚠️ Pre-flight Checks

Check 1: Feature Path Required

If no feature path was provided, resolve work-first: features live inside each work's own worktree, so they cannot be listed from the main checkout until one is entered — the feature glob below runs only after that.

Enumerate works cross-worktree: run bash .cursor/aid/scripts/works/enumerate-works.sh (main tree + every git worktree; never the local .aid/works/ glob, which is empty on master), taking each record's field-1 work_id.

Zero works → STOP.

No works found. Run /aid-describe first.

Exit.

Single work → normalize its work_id to the bare work-NNN branch name and locate+enter it (.cursor/aid/templates/downstream-worktree-entry.md — the same mechanics as "Locate + Enter the Work's Worktree" below), then list that work's features locally, now visible inside the entered tree:
```
Usage: /aid-specify feature-001

Available features in work-001-user-auth:
  feature-001-login        [No STATE — not started]
  feature-002-password      [In Discussion — 2/5 sections]
```
Scan .aid/works/{work}/features/feature-*/ inside the entered worktree. For each, check the work STATE.md ## Features State row for this feature and show status. Exit.
Multiple works → present the work list:
```
Usage: /aid-specify work-001/feature-001

Available works:
  work-001-user-auth
  work-002-reporting

[1] work-001-user-auth
[2] work-002-reporting
```
Ask which work. Once chosen, normalize + locate+enter it exactly as step 3, then list its features the same way. Exit.

Shortcut: If only one work exists, accept bare feature-001 and resolve automatically — this is step 3 above; the single-work case already enters the work before the feature glob runs.

Locate + Enter the Work's Worktree

As soon as the work-NNN prefix is parsed / auto-selected (right after Check 1) and before Check 2 globs .aid/works/{work}/features/…/SPEC.md, follow .cursor/aid/templates/downstream-worktree-entry.md to normalize <work-id> to its bare work-NNN branch name, locate the worktree (which always exits 0 and returns <path>\t<status>), and enter the returned path. Keep the defensive empty-path/non-zero backstop that stops rather than operate blindly — it should not fire against the real helper. Never create a new worktree — creation belongs to the work-starting skills only.

Check 2: Feature Exists

Resolve the feature path using prefix matching (glob):

feature-001 → match .aid/works/{work}/features/feature-001-*/SPEC.md
work-001/feature-002 → match .aid/works/work-001-*/features/feature-002-*/SPEC.md

If zero matches: Exit with instruction to run /aid-describe first. If multiple matches: List them, ask user to be more specific. Exit. If exactly one match: Use that path. Print: [Resolved: {full-path}]

Check 3: Plan Mode

✅ Default or Auto-accept edits → Proceed.
❌ Plan mode → STOP. Tell the user to switch out of Plan Mode.

Arguments

| Argument | Effect | |----------|--------| | work-NNN/feature-NNN | Required. Path to the feature to specify. | | feature-NNN | Shortcut when only one work exists. | | --reset | Clear ## Technical Specification from SPEC.md and delete STATE.md. |

State Detection

All paths relative to .aid/works/{work}/features/{feature}/.

State 1: No Feature State row in work STATE.md               → INITIALIZE
State 2: Feature State: In Discussion                         → CONTINUE
State 3: Feature State: Spike Needed                          → SPIKE
State 4: Feature State: Blocked (loopback pending)            → BLOCKED
State 5: Feature State: Ready                                 → REVIEW (enter loop at step 4)

Print the state-entry line and "you are here" map. Examples for INITIALIZE:

[State: INITIALIZE] — First run for this feature; load context, determine sections, begin The Loop.
aid-specify ({feature})  ▸ you are here
  [● INITIALIZE ] → [ CONTINUE ] → [ REVIEW ] → [ DONE ]

For CONTINUE:

[State: CONTINUE] — Resume The Loop (Propose → Discuss → Write → Review) for the next pending section.
aid-specify ({feature})  ▸ you are here
  [✓ INITIALIZE ] → [● CONTINUE ] → [ REVIEW ] → [ DONE ]

For REVIEW:

[State: REVIEW] — All sections complete; re-review entire spec against current KB and codebase.
aid-specify ({feature})  ▸ you are here
  [✓ INITIALIZE ] → [✓ CONTINUE ] → [● REVIEW ] → [ DONE ]

For DONE (Ready):

[State: DONE] — Spec is Ready and has met the minimum grade.
aid-specify ({feature})  ▸ you are here
  [✓ INITIALIZE ] → [✓ CONTINUE ] → [✓ REVIEW ] → [● DONE ]

SPIKE:

[State: SPIKE] — Feature has unknowns requiring investigation; spike work needed.
aid-specify ({feature})  ▸ you are here
  [✓ INITIALIZE ] → [ CONTINUE ] → [● SPIKE ] → [ REVIEW ] → [ DONE ]

BLOCKED:

[State: BLOCKED] — Feature has a pending loopback that must be resolved before continuing.
aid-specify ({feature})  ▸ you are here
  [✓ INITIALIZE ] → [ CONTINUE ] → [● BLOCKED ] → [ REVIEW ] → [ DONE ]

Dispatch

| State | Detail | Worker | Advance | |-------|--------|--------|---------| | INITIALIZE | references/state-initialize.md | aid-architect | → CONTINUE | | CONTINUE | references/state-continue.md | aid-architect | → REVIEW | | SPIKE | references/state-spike.md | inline | → CONTINUE | | BLOCKED | references/state-blocked.md | inline | → CONTINUE | | REVIEW | references/state-review.md | aid-reviewer | → DONE | | DONE | references/state-done.md | inline | → halt |

On state entry, print [State: NAME] + the "you are here" map from State Detection above. When a state completes, route by its **Advance:** type (per state-machine-chaining.md):

CHAIN → begin the next state's reference doc within the same invocation; no exit.
PAUSE-FOR-USER-ACTION / PAUSE-FOR-USER-DECISION → print the pause reason + resume command and exit.
HALT → print the closing summary and exit.

Handling Outcomes During Discussion

Read references/handling-outcomes.md for how to handle KB issues, requirement gaps, spikes, blocks, feature splits, and feature merges during discussion.

Known Issues & Quality Gates

Read references/known-issues-scope.md for the known-issues filter (what to register vs skip) and feature-specific quality gates (test/lint requirements beyond baseline).

Conversation Style

Do:

Propose concrete solutions based on what exists
Reference specific files, classes, patterns
Explain trade-offs when multiple approaches exist
Push back if the user contradicts KB patterns
Admit when you don't know something

Don't:

Ask generic questions — propose based on KB
Generate walls of spec without discussion
Move to next section without clear agreement
Be a yes-machine — if you see a problem, say so

The rhythm:

Agent: "Based on {KB}, I propose {concrete approach}."
Dev:   "Actually, we should do X because Y."
Agent: "Good point. That means we also need Z. Updated approach..."
Dev:   "Yeah, works."
Agent: [writes] [reviews: ✅ consistent] [next section]
