Help turn ideas into fully formed designs and specs through natural collaborative dialogue.
Start by understanding the current project context and authority boundary, then ask questions one at a time to refine the idea. Once you understand what you're building, present the smallest design artifact that stabilizes the work and get the required approval.

fast, batch, 快问, or 一次问几个), ask at most three independent decision questions. Give each question its recommendation and trade-off, then wait for the user's responses. Return to deep pace for dependent follow-ups.Do not force this workflow onto low-complexity work. A tiny wording edit, single-owner bug fix, simple config/status question, local utility change, or mechanical multi-file change can proceed through concise intent, baseline check, TDD/debugging, and verification without any new document. Run the Doc Necessity Gate before writing any spec, plan, ADR, or baseline artifact:
You MUST create a task for each of these items and complete them in order:
CONTEXT.md language without
loading active modelingTaskIntentDraft, BaselineReadSetHint, BaselineUsageDraft, ImpactStatementDraftThe terminal state is invoking writing-plans. Do NOT invoke any other implementation skill.
Understanding the idea:
establishing-project-context; do not leave the resolution only in the spec.Working artifacts: Keep four drafts: TaskIntentDraft (outcome, goal,
success evidence, stop condition, non-goals, scope, risks),
BaselineReadSetHint (candidate docs, authority gaps),
BaselineUsageDraft (required refs, optionally delivered context refs,
acknowledged-before-plan refs, cited refs, missing refs, advisory decision),
and ImpactStatementDraft (affected layers, owners, invariants, compat,
non-goals). Refresh when scope changes.
Compact output contract: Aegis Visibility, TaskIntentDraft, BaselineReadSetHint,
BaselineUsageDraft, Requirement Ready Check, ImpactStatementDraft,
Existence Check, Product Risk Lens, Architecture Integrity Lens,
Baseline Role Alignment, Plan-Time Complexity Check, Options, and
Decision Needed. Use this compact shape before expanding into a full design
structure.
Aegis Visibility for this workflow names why design/spec clarification comes
before implementation and what drift, overbuild, wrong-owner, or missing
acceptance risk that restraint reduces. Keep it natural and task-specific; do
not turn it into a fixed skill trace.
Use a compact BaselineUsageDraft whenever the design direction depends on
specific baseline docs or current-authority refs:
BaselineUsageDraft:
- Required baseline refs:
- Delivered context refs:
- Acknowledged before plan refs:
- Cited in design refs:
- Missing refs:
- Decision: continue | needs-baseline-readback | needs-verification | pause-for-user | blocked
Delivered context refs is optional host-projected bookkeeping only. It is not
authoritative proof that a host injected or the model internally consumed a
context payload. The artifact exists to make baseline/context attention drift
visible before the design is recommended or approved.
Use a compact Requirement Ready Check before recommending a design when the
requirement is not already confirmed and complete:
Requirement Ready Check:
- Requirement source refs:
- Goals and scope refs:
- User / scenario refs:
- Requirement item refs:
- Acceptance / verification criteria refs:
- Open blocker questions:
- Decision: ready | needs-source | needs-goal-alignment | needs-scenario | needs-acceptance-criteria | needs-clarification | needs-user-decision | blocked
Treat task intent, conversation, source documents, and agent inference as
candidate requirement sources until project authority confirms them. If the
decision is not ready, keep the design at proposal/spec clarification level;
do not turn the gap into implementation tasks.
Existence Check: Before recommending an approach that adds a new owner,
skill, artifact, host adapter, fallback, compatibility path, workflow step, or
benchmark metric, check whether it needs to exist. Use
docs/current/AEGIS_MINIMALITY_REFERENCE.md as the reference. Do not force this
onto ordinary feature design that reuses existing owners and artifacts.
Existence Check:
- Proposed new surface:
- Existing owner / reuse candidate:
- Why existing surface is insufficient:
- Creation proof:
- Entropy / retirement impact:
- Decision: reuse-existing | add-with-proof | defer | reject | needs-first-principles-review
If the decision is reuse-existing, recommend the reuse path instead of a new
surface. If the decision is add-with-proof, carry the proof, verification
signal, and any retirement trigger into the design/spec.
Product Risk Lens: For ambiguous product, feature, UI, workflow, or architecture choices, add a compact review lens, not persona roleplay:
Product Risk Lens:
- Value:
- Non-goals:
- Trade-offs:
- Decision needed:
This is a review lens, not persona output. It does not override baseline evidence, approved requirements, or current authority docs; it only makes the product risk and decision point visible before implementation.
Plan-Time Complexity Check: Before choosing an implementation direction for medium/high work, inspect the likely owner files and current shape. This is an advisory design pressure check, not a gate and not completion authority. Do not force it onto tiny low-risk edits.
Use using-aegis/references/complexity-governance.md for the shared artifact
classes, pressure-signal interpretation, and over-budget handling.
Complexity Budget:
- Artifact class:
- Target files / artifacts:
- Current pressure:
- Projected post-change pressure:
- Budget result: within-budget | at-risk | over-budget
- Planned governance:
Plan-Time Complexity Check:
- Better file boundary:
- Recommendation: edit-in-place | extract helper | add owner file | split task | defer refactor
Exploring approaches: Propose 2-3 approaches with trade-offs and recommendation. Make scope boundary explicit: what's in, what's deferred, what belongs elsewhere.
Before approach selection, use Existence Check for any proposed new surface.
Escalate to first-principles-review and its Decision Hygiene Review when
the candidate direction still introduces a new owner, duplicate owner,
fallback, adapter, compat-only carrier, delete-first question, unverified
assumption, or "long-term stable" claim after the existence check. Do not make
either check a universal design ceremony; return to this workflow once the
decision surface is clean.
When the central decision is internal retirement vs compat retention vs
persistent-state confirmation, compose anti-entropy-governance. It classifies
the deletion target, chooses delete-first | compat-exception | confirmation-first, and keeps destructive authority outside the design skill.
Use the narrower Architecture Integrity Lens when the main risk is not broad
strategy but architecture coherence: unclear canonical owner, responsibility
overlap, caller-side fallback, stale path carrying real logic, or a possible
higher-level owner / contract / source-of-truth simplification. The lens should
answer invariant, canonical owner / contract, responsibility overlap,
higher-level simplification, retirement / falsifier, and verdict before the
approach is recommended.
Baseline Role Alignment: When a question may involve both "what should be built" and "where it should live", keep requirement truth separate from architecture truth:
Baseline Role Alignment:
- Product / Requirement Baseline:
- Architecture / Runtime Boundary Baseline:
- Result: aligned | Design Defect | Implementation Drift | missing-authority | needs-clarification
- scope: requirements | architecture | both
- Next action:
Use Design Defect when the relevant requirement, design, or baseline is wrong.
Use Implementation Drift when the work deviates from a correct unchanged
baseline. Architecture Defect and Architecture Drift remain compatibility
aliases for architecture-scoped Design Defect and architecture-scoped
Implementation Drift. This is a review lens, not a runtime gate or completion
authority.
Presenting the design: Scale sections to complexity. Cover only the surfaces that matter: architecture, components, data flow, error handling, testing, compatibility boundary. Get approval for the design before implementation when behavior, contract, architecture, or user-facing flow is being decided.
ADR signals: When the design/spec touches durable architecture surfaces (owner, public contract, artifact shape, dependency direction, source-of-truth, host compatibility, runtime-ready boundary, fallback, adapter, or retirement schedule), mark the ADR signal, source refs, real alternatives, and expected baseline-sync question for later completion. Do not create accepted architecture memory from unexecuted ideas.
Design for isolation: Each unit = one clear purpose, well-defined interface, testable independently. Can someone understand it without reading internals? Can you change internals without breaking consumers?
Existing codebases: Follow existing patterns. Include targeted improvements only when they serve the current goal. If the design touches contracts, compat, fallbacks, or duplicated owners → call it out directly.
Documentation:
Aegis Project Workspace initialization (first creation only):
If docs/aegis/ does not exist and configured Aegis workspace support is
available, initialize the target project:
python <aegis-workspace-helper> init --root <target-project-root>.
If installed Aegis workspace support is unavailable, create it manually:
a. Create docs/aegis/README.md — describes workspace purpose and structure
b. Create docs/aegis/INDEX.md — empty index, will be appended below
c. Create docs/aegis/BASELINE-GOVERNANCE.md from the template in
"BASELINE-GOVERNANCE.md Template" section below
d. If the project has existing code, create an initial baseline snapshot:
docs/aegis/baseline/YYYY-MM-DD-initial-baseline.md using the
"Initial Baseline Snapshot Template" below
If docs/aegis/ already exists, use it — do not recreate.
Write the validated spec artifact when needed: Use the smallest artifact that stabilizes the task:
docs/aegis/specs/YYYY-MM-DD-<topic>-brief.md for medium
tasks that need what/why/acceptance pinned before planning.docs/aegis/specs/YYYY-MM-DD-<topic>-design.md for high
complexity, architecture, contract, migration, cross-module, or ambiguous
behavior requiring user review.
Specs always go to specs/ — never to work/. docs/aegis/work/
holds session-level drafts, not project documents; only promote a draft to
specs/ or plans/ when the Doc Necessity Gate passes.Update INDEX.md:
Prefer configured Aegis workspace support: python <aegis-workspace-helper> append-index --root <target-project-root> --path docs/aegis/specs/<filename>.md --kind spec --title "<title>". If workspace support is unavailable, append the new spec entry
to docs/aegis/INDEX.md manually.
After the append, run python <aegis-workspace-helper> check --root <target-project-root> when configured workspace support is available. This validates
structure and index coverage only; it does not grant completion authority.
INDEX bookkeeping: creating a document registers it; updating an existing
document does not change the index; superseding or deleting a document
updates the index.
Commit the design document to git.
Include the latest TaskIntentDraft, BaselineReadSetHint,
BaselineUsageDraft, and ImpactStatementDraft inline or in an appendix
when they materially shaped the design.
Record explicit non-goals and compatibility boundaries so the later implementation plan does not drift.
Cross-repo changes: decide per change surface per repo; a durable cross-repo contract is recorded as an ADR in the owning repo, with the other side carrying only its local impact (mirror relationship, no duplication).
Spec Self-Review: After writing the spec document, look at it with fresh eyes:
first-principles-review Decision Hygiene Review or Architecture Integrity Lens result is reflected or explicitly marked unnecessary.Fix any issues inline. No need to re-review — just fix and move on.
User Review Gate: After a Design Spec review loop passes, ask the user to review the written spec before proceeding:
"Spec written and committed to
<path>. Please review it and let me know if you want to make any changes before we start writing out the implementation plan."
Wait for the user's response when this workflow requires review. If they request changes, make them and re-run the spec review loop. Only proceed once the user approves. For a small Spec Brief created only to pin medium-task acceptance, user review may be concise unless project rules require a formal approval step.
Implementation:
When creating docs/aegis/BASELINE-GOVERNANCE.md for the first time, use this template:
# Baseline Governance
## 1. Baseline Roles
- Product / Requirement Baseline: confirmed requirement sources, target state,
goals and scope, users / scenarios, requirement items, acceptance /
verification criteria, non-goals, workflow constraints, open questions,
change records, and approved requirement/spec intent.
- Architecture / Runtime Boundary Baseline: canonical owner, contract,
source-of-truth boundary, dependency direction, compatibility, runtime-ready
boundary, and retirement state.
## 2. Design Defect
A confirmed error, gap, contradiction, or wrong abstraction IN the relevant
requirement, design, or baseline.
- Fix the defective requirement/design/baseline first.
- Then align implementation to the corrected baseline.
- Do NOT patch implementation around a defective baseline.
## 3. Implementation Drift
Implementation, plan, review, or documentation has deviated from a confirmed,
correct, unchanged requirement or architecture baseline.
- Return to baseline via the simplest stable path.
- Do NOT "update baseline to match drift" without explicit review.
## 4. Compatibility Aliases
- Architecture Defect = architecture-scoped Design Defect.
- Architecture Drift = architecture-scoped Implementation Drift.
- New findings should report Design Defect / Implementation Drift plus
`scope: requirements | architecture | both`.
## 5. Baseline Check Protocol
Before non-trivial changes:
1. Read the latest Product / Requirement Baseline candidate.
2. Read the latest Architecture / Runtime Boundary Baseline candidate.
3. Compare current work against requirement acceptance and architecture owner /
contract boundaries.
4. Check for new anti-patterns not recorded in known list.
5. Report: aligned / Design Defect / Implementation Drift /
missing-authority / needs-clarification, with
`scope: requirements | architecture | both`.
## 6. Architecture Review — 7 Dimensions
After each non-trivial change:
1. **Ownership integrity** — every component has exactly one canonical owner
2. **Module boundaries** — no unauthorized cross-module coupling
3. **Contract changes** — all API/signature/behavior contract changes documented
4. **Cascade proliferation** — no new cascading dependency chains
5. **Dependency direction** — dependencies flow toward stability
6. **Retirement completeness** — old owners/fallbacks/paths removed or scheduled
7. **Entropy flow** — net complexity decreased or stayed; no unjustified new entities
## 7. Hard Boundaries
- BASELINE-GOVERNANCE.md is the constitution for THIS project's Aegis workspace
- Baseline snapshots in `baseline/` are evidence, not authority
- ADRs in `adr/` record decisions; they do not replace baseline governance
- This file is NEVER auto-updated — changes require explicit user review
When creating the first docs/aegis/baseline/YYYY-MM-DD-initial-baseline.md:
Bootstrap the project's dual baselines instead of writing a flat repo inventory.
The first baseline should make later Baseline Role Alignment checks possible
even when the repo is still early or partially defined.
Minimum shape:
# <Project> Initial Baseline
Date: `YYYY-MM-DD`
Status: `initial dual-baseline snapshot`
## 1. Purpose
- why this baseline exists
- what later alignment checks should use it for
## 2. Workspace Structure
- top-level directories, entry points, substrate roots, or seams worth tracking
## 3. Current Authority Surfaces
- README / AGENTS / ADR / spec / baseline / external reference roots
- current authority gaps or missing documents
## 4. Product / Requirement Baseline
### 4.1 Current Truth
- confirmed requirement sources or current authority gaps
- target state, goals, and scope
- target users, roles, usage scenarios, or system scenarios
- functional, quality, constraint, and delivery / transition requirement items
- acceptance / verification criteria and evidence expectations
- success evidence, value claim, or phase focus already fixed
### 4.2 Non-negotiables
1. ...
### 4.3 Product Non-goals
- ...
## 5. Architecture / Runtime Boundary Baseline
### 5.1 Current Truth
- canonical owner or substrate split
- contract / source-of-truth boundary
- dependency direction or owner layering already fixed
### 5.2 Architecture Non-negotiables
1. ...
### 5.3 Architecture Non-goals
- ...
## 6. Ownership / Contract Snapshot
- important surface -> current owner
- contract seams, missing seam inventory, or boundary gaps
## 7. Current State and Risks
- current stage
- known risks, unknowns, or missing evidence
## 8. Alignment Use
- when to read the Product / Requirement Baseline
- when to read the Architecture / Runtime Boundary Baseline
- when to report `scope: both`
## 9. Compatibility Boundary
- what must NOT break during early work
Do not collapse the first bootstrap baseline into a generic 10-field checklist. If the project is sparse, keep sections short and mark authority gaps explicitly instead of guessing.
