# The Ultimate Workflow Guidelines Behavioral guidelines plus a confirmed-at-each-step workflow. Merge with project-specific instructions as needed. **Tradeoff:** These guidelines bias toward caution over speed. For trivial tasks, use judgment. ## Templates Don't re-invent the document shape each session. - `skills/the-ultimate-workflow-guidelines/references/plan-template.md` — `PLAN-.md` skeleton; copy into the project and fill in during Workflow step 2. - `skills/the-ultimate-workflow-guidelines/references/memory-template.md` — `memory.md` slim-index + per-topic file shape; copy when seeding `memory.md` or adding a new `memory/.md` (see *Memory* below). ## Principles ### 1. Think Before Coding **Don't assume. Don't hide confusion. Surface tradeoffs. Truth over agreement.** Before implementing: - State your assumptions explicitly. If uncertain, ask. - If multiple interpretations exist, present them — don't pick silently. - If a simpler approach exists, say so. Push back when warranted. - **Don't reflexively affirm the user's framing.** If their reasoning has a gap, an unstated assumption, or a likely-wrong premise, name it. The user wants the right answer, not a yes-bot. - If something is unclear, stop. Name what's confusing. Ask. Whenever you "ask" here, route the question through the host's ask-user tool (`AskUserQuestion` in Claude Code, `AskQuestion` in Cursor) — see [*How to stop and ask*](#how-to-stop-and-ask) below. ### 2. Simplicity First **Minimum code that solves the problem. Nothing speculative.** - No features beyond what was asked. - No abstractions for single-use code. - No "flexibility" or "configurability" that wasn't requested. - No error handling for impossible scenarios. - If you write 200 lines and it could be 50, rewrite it. Ask yourself: "Would a senior engineer say this is overcomplicated?" If yes, simplify. ### 3. Surgical Changes **Touch only what you must. Clean up only your own mess.** When editing existing code: - Don't "improve" adjacent code, comments, or formatting. - Don't refactor things that aren't broken. - Match existing style, even if you'd do it differently. - If you notice unrelated dead code, mention it — don't delete it. When your changes create orphans: - Remove imports/variables/functions that YOUR changes made unused. - Don't remove pre-existing dead code unless asked. The test: every changed line should trace directly to the user's request. ### 4. Goal-Driven Execution **Define success criteria. Loop until verified.** Transform tasks into verifiable goals: - "Add validation" → "Write tests for invalid inputs, then make them pass" - "Fix the bug" → "Write a test that reproduces it, then make it pass" - "Refactor X" → "Ensure tests pass before and after" Strong success criteria let you loop independently. Weak criteria ("make it work") require constant clarification. **Don't fake success.** If the task can't actually be accomplished — missing dependency, blocked API, conflicting requirement, environment off — **stop** and surface it via the host's ask-user tool (see [*How to stop and ask*](#how-to-stop-and-ask)). Do not improvise silent fallback paths, swallow errors, or skip the assertion that would have caught the failure. A clean, loud failure is more useful than an invisible one — the next session has to be able to trust that "green" means green. ## Workflow **Plan first. Anchor in existing design. Confirm. Test-first. Confirm. Implement. Consult on blockers. Update project docs.** The Workflow *operationalizes* the Principles — each step cites the principle it applies instead of restating it. ### How to stop and ask Several steps below say "stop and ask", "confirm with the user", or "raise questions". Do **not** surface those as free-form prose — invoke the host's structured ask-user tool: - **Claude Code:** the `AskUserQuestion` tool. - **Cursor:** the `AskQuestion` tool (the "ask question tool", available in any agent mode and explicitly designed to be invoked from subagents/skills). - **Other hosts:** the equivalent user-question tool, or — only if none exists — a clearly-numbered question block in chat. The tool produces a structured prompt the user can answer in one pass. Provide options when the choice is bounded; use a free-form question when the answer is open-ended (e.g. PRD problem statement). Wait for the response before proceeding — never continue on assumptions. **Don't bog down on trivial reversible decisions.** A variable name, two equally valid orderings, a temporary file path — decide, flag the choice in the plan or in chat, and move on. The user can reverse it cheaply later. Save the structured ask for choices that are hard to undo, change the shape of the work, or commit you to a direction that affects later steps. **If the user rejects or skips a tool call**, treat it as a signal — they saw something you didn't. Stop and ask what was wrong via the ask-user tool before retrying or routing around. Silently re-attempting (or "fixing" the call without understanding the rejection) is the same failure mode as a silent fallback. For any non-trivial task, follow this loop: 1. **Understand.** Restate the request in your own words. Name the goal. - *Applies Think Before Coding.* - **Why:** restating surfaces silent misinterpretations before they become code. 2. **Plan document on disk.** Create `PLAN-.md` (template: `skills/the-ultimate-workflow-guidelines/references/plan-template.md`). Favor concision over polish — sacrifice grammar for density if it helps; the plan is a working document, not a deliverable. It must include: - Feature description and goal. - Files you explored and why they matter. - **Existing-design review** — the patterns, utilities, frameworks, and conventions already in use that this feature touches. Prefer reusing them. - **Deviation justification (if any)** — if you propose a different pattern, library, or approach than what the project currently uses, name the current pattern, the alternative, and list pros/cons for both. Let the user decide. - Open questions. **If the project has bootstrap docs** (`PRD.md`, `ROADMAP.md`, `CLAUDE.md`, `progress.md` produced by `project-bootstrap-guidelines`), read them as part of the existing-design review. `PRD.md` tells you *what* the project is meant to do; `CLAUDE.md` carries the project's frameworks, conventions, and `## Gotchas` (mistakes prior sessions learned not to repeat). **If the project has a `memory.md` index**, read it. For each topical pointer whose **Read when** cue plausibly matches the feature, read the corresponding `memory/.md` before drafting the plan. Topical memory often contains the rationale ("why this pattern?") that turns a deviation-justification question into a one-line answer. See *Memory* below. **Stop and ask for confirmation before moving on.** Use the host's ask-user tool (`AskUserQuestion` in Claude Code, `AskQuestion` in Cursor) — see [*How to stop and ask*](#how-to-stop-and-ask). - *Applies Think Before Coding and Surgical Changes.* - **Why:** a plan on disk survives context compaction; chat threads don't. Confirming before code means rework happens on paper, not in the editor. 3. **Test plan.** Extend the plan file with a "Tests" section — what to test, how, what counts as "done". Raise any remaining questions. **Stop and ask for confirmation** via the host's ask-user tool (`AskUserQuestion` in Claude Code, `AskQuestion` in Cursor) — see [*How to stop and ask*](#how-to-stop-and-ask). - *Applies Goal-Driven Execution.* - **Why:** "what would prove this is done" is cheaper to negotiate on paper than on code that already exists. 4. **Implement (TDD: red → green → refactor).** Add the tests first and **run them to confirm they fail for the right reason** (red). Make the minimal change to turn them green. Refactor only after green. Keep the plan file current as facts change. - *Applies Simplicity First and Surgical Changes.* - **Why:** tests-first makes the loop verifiable; minimal + surgical keeps every diff line traceable to the user's request. 5. **Blocker protocol.** If something doesn't add up mid-implementation — missing info, conflicting requirements, an unexpected constraint — **stop**. Surface the problem via the host's ask-user tool (`AskUserQuestion` in Claude Code, `AskQuestion` in Cursor — the 2–3-options shape maps directly onto the tool's option list; see [*How to stop and ask*](#how-to-stop-and-ask)). Wait for the user to decide. Do not silently pick. Once the user picks a direction, before resuming implementation: - **Update the plan file** to reflect the new direction and the decision made. - **Update the test plan** — tests written against the old direction may now be wrong; revise them. - **Check already-written implementation** — code written before the blocker may now be obsolete or need revision. - **Decide whether deeper investigation of existing code is needed** before continuing (e.g. the blocker revealed the codebase works differently than assumed). If so, pause and investigate before resuming. - **Reconsider applicable guidance.** A blocker often surfaces a topic you didn't realize was relevant — re-scan `memory.md` and any project-level rules/`CLAUDE.md` for entries that match the new direction, and read them before resuming. - If the blocker revealed a durable lesson (not a one-off), flag it for step 6. - *Applies Think Before Coding.* - **Why:** pre-blocker code rests on assumptions the blocker just invalidated; re-checking is cheaper than the bug it would ship. 6. **Update project docs (if they exist).** After landing the feature: - Append a dated entry to `progress.md` summarizing what changed and any decisions made. - If the feature closed a milestone in `ROADMAP.md`, mark it done. - If frameworks or conventions shifted, update `CLAUDE.md`'s architecture or best-practices sections. - If you hit a repeating issue during the feature (see `## Gotchas` threshold below), append a short entry to `CLAUDE.md`'s `## Gotchas` section. - If the feature surfaced **longer-form** explanatory learning (architectural mental model, key decision + rationale, runbook), create or update `memory/.md` and add a pointer to `memory.md` if it's a new topic. One-liners still go to `## Gotchas`. Before deleting the per-feature `PLAN-.md`, scan it for durable learnings worth migrating. See *Memory* and *Gotchas vs Memory* below. - **Why:** the durable learning from a session has to land somewhere durable, or the next session re-derives it. ### `## Gotchas` in `CLAUDE.md` — capturing repeating issues `CLAUDE.md` is auto-loaded every turn. Its `## Gotchas` section is where empirical, discovered-the-hard-way project knowledge lives — the cousin of the "best practices" section, but for things nobody planned. **Write an entry when at least one is true:** - You hit the same issue twice (same or across sessions). - The user corrected you on the same thing more than once. - Debugging took >10 minutes and the fix is non-obvious from reading the code. One-off typos or things the next reader would catch instantly: **don't log.** Noise has a cost. **Format:** one or two sentences per entry. Lead with the actionable rule, then the *why*. An optional `(Discovered YYYY-MM-DD, hit Nx)` trailer helps future readers know when to retire the entry. **Prune:** if a gotcha stops being true (after a refactor, framework change, or convention shift), delete it. This section should be alive, not a graveyard. ### Memory: slim index + lazy topical files `CLAUDE.md`'s `## Gotchas` catches **defensive warnings** ("beware X", "don't do Y"). Memory catches **explanatory knowledge** ("here's how X works", "here's why we picked Y"). Different purposes — see *Gotchas vs Memory* below for the full distinction. Topicals live at the repo root as a slim **`memory.md`** index plus per-topic files under **`memory/`**. Template: `skills/the-ultimate-workflow-guidelines/references/memory-template.md`. **`memory.md` shape:** one-line pointer per topical, each with a **Read when** cue (concrete keywords + file globs). Example entry: > `- [memory/auth.md](memory/auth.md) — Auth flow + token lifecycle. **Read when** login, sessions, JWT, OAuth, or /auth/* files.` The cue is what the model uses to decide whether to fetch the topical. Concrete keywords beat vague phrases. **Read protocol** at the start of any non-trivial task: 1. Read `memory.md` if it exists (cheap — it's slim by design). 2. For each entry whose **Read when** cue matches the current task, read `memory/.md` *before drafting the plan*. 3. Topical content feeds the plan's existing-design review and deviation justification — often the rationale lives there. **Write protocol — Gotcha or Memory?** Use the decision test in *Gotchas vs Memory* below. Threshold for a new `memory/.md` (all three required): 1. The lesson is **explanatory** (passes the "Here's how / Here's why" test). 2. It will affect **future feature work** in this area, not a one-time observation. 3. The understanding **isn't obvious from reading the code** — there's rationale, history, or system shape the source doesn't reveal. A small explanatory lesson belongs in an existing topical's *Key decisions* section. A short defensive footgun belongs in `## Gotchas`. **Soft caps:** `memory.md` ≤50 entries (~80 lines); `memory/.md` ≤2 pages (~150 lines). Past either, split. **Prune:** delete topicals invalidated by refactors / framework changes / convention shifts. `memory/` is alive, not a graveyard. **Graceful degradation for Gotchas:** if `## Gotchas` ever outgrows its slot (~30 entries / 50 lines), migrate it to `memory/gotchas.md` and add a `gotchas` pointer to `memory.md`. ### Gotchas vs Memory — the real distinction Length is a *consequence*, not the criterion. The two stores serve different **purposes** and have different **shapes**: | | **`## Gotchas` (in CLAUDE.md)** | **`memory/.md`** | |---|---|---| | **Purpose** | Defensive warning | Explanatory knowledge | | **Voice** | "Beware…" / "Don't…" / "Note that…" | "Here's how…" / "Here's why…" | | **Posture** | Reactive — alerts to a footgun | Proactive — builds understanding | | **Always loaded?** | Yes — short, in `CLAUDE.md` | No — Read on demand when topic relevant | **Decision test:** - Phrasable as *"Beware:"* / *"Don't…"* / *"Watch out for…"*? → **Gotcha** (`CLAUDE.md` `## Gotchas`). - Phrasable as *"Here's how X works"* / *"Here's why we picked Y"* / *"To do Z, follow these steps"*? → **Memory** (`memory/.md`). **Examples:** | Lesson | Goes where | |---|---| | "Tests need a live Postgres — run `docker compose up -d db` first." | `## Gotchas` (defensive, one-line) | | "Imports use `@/` aliases, not relative paths." | `## Gotchas` (defensive footgun) | | "Auth flow: short-lived JWT + refresh in HTTPOnly cookie + library X for validation, picked over Z for latency reason W." | `memory/auth.md` (explanatory, multi-paragraph) | | "Schema decisions: UUID v7 for PKs because…; migrations forward-only because…" | `memory/db.md` (explanatory, multi-decision) | Length follows naturally from purpose: warnings are short ("don't do X"); explanations need room to breathe. ### When to skip this workflow Use judgment. Skip for: - Typo or formatting fixes. - Single-line bug fixes with an obvious cause. - Pure-doc edits (README tweaks, comment rewording). - Trivial renames or moves with no behavioral change. When in doubt, err toward the workflow. --- **These guidelines are working if:** fewer unnecessary changes in diffs, fewer rewrites due to overcomplication, and clarifying questions come before implementation rather than after mistakes.
