Refine Ticket

Refine ticket

The Refine phase of Refine → Plan → Act: turn a raw ticket into a validated requirements document a fresh session can plan from. Analysis only — it defines what must be true when the work is done, never how to build it, and never touches code.

What, not how — but verified against the code

You cannot define the "what" in a vacuum. Every requirement must be checked against the actual code, config, and design — a ticket may be stale, ambiguous, contradicted by the codebase, or depend on upstream work that isn't implemented yet (e.g. a prerequisite ticket still open). Reading the code here is for validating requirements, not for designing the solution.

Golden rule: never guess — ask

• Anything determinable by reading the code, resolve by reading the code — never ask the user about

it.

• Anything not determinable from ticket + code, ask — never fill the gap with a plausible

assumption.

• Local environment state (config files, DB contents, env vars) describes only the machine it's on

— never assume it matches the environment where the reported behaviour occurred; ask the user to confirm such values.

• Treat "this probably works like X" as a question, not a fact. Keep "I confirmed X", "the ticket

claims X", and "I assume X" distinct; the latter two never become the first without evidence.

• Before declaring something missing, broaden the search — "not found under the name the ticket

used" is not "not present".

• Verify both sides of an integration: if a requirement relies on another layer behaving a certain

way, open that layer and confirm it.

Grill to resolve every branch

After gathering and code-verifying, grill the user — interview relentlessly, never guessing what they could clarify — to close every remaining decision:

• One question at a time, each with your recommended answer.
• If any part of a question is answerable from the codebase, explore it rather than ask — never

bundle a code-answerable sub-question into a grill. "Which name, type, shape, or pattern fits?" is code-answerable: match the closest existing analogue, and let that verified convention outrank the ticket's contrary suggestion. Grill only on what genuinely remains (product intent, cross-task timing).

• Walk each branch of the decision tree, resolving dependencies between decisions, until there is

shared understanding and no open branch that blocks implementation.

Separate two kinds of uncertainty:

• Blocking — implementation can't proceed without it (a contradiction, a missing referenced

file). Resolve during grilling, before writing the file.

• Non-blocking — a reasonable default exists but a human should confirm. Record under Open

questions with your tentative answer.

"Already exists" / "reuse X" is a directive

When the ticket says a capability exists or names something to reuse, find what's behind it (the service method, query, SP it calls) and anchor the requirement on the smallest extension — relax a parameter, widen a filter, lift a guard. "Not an exact match" doesn't license a net-new build: reuse-vs-build-new is a blocking question for the user, never a silent default.

Reconcile against the design when one is referenced

When a ticket points at a design (mockup, screenshot, prototype, design-tool link), that design is part of the spec. Visual decisions made without seeing it lock in wrong defaults.

• If you cannot actually see the referenced design, ask for it before proceeding. A link you can't

render is not a design you've read. Prefer a copy already saved with the ticket over re-fetching.

• Once you can see it, treat visual specifics as contract-level: currency, date, and number

formatting, empty and error states, label wording, spacing, alignment, iconography. The default for "is this in the design?" is match the design, not do the minimum.

• Any visual choice you'd otherwise make blind is an Open question, never silently defaulted.

Output: the REQUIREMENTS file

Must stand alone for a fresh session with no memory of this conversation and no access to the ticket — this is the single most important constraint. No "as discussed", "we agreed", or "see ticket".

Location:

• If the ticket input is a local file, write the REQUIREMENTS file in the same directory,

replacing .TICKET with .REQUIREMENTS (e.g. FOO.TICKET.md → FOO.REQUIREMENTS.md); if the input doesn't follow that convention, append .REQUIREMENTS before .md.

• If there is no local ticket file (a tracker URL/ID, pasted text), follow the project's

planning convention for where planning documents live (per the project's or user's rules — don't assume a fixed path, ask when not sure). Propose a kebab-case ` (prefix the tracker id when the ticket is bound to one) and the target path, **confirm both with the user**, then write .REQUIREMENTS.md` there.

Six parts (Verified codebase facts, Overrides, and Open questions may be empty — don't pad):

1. Context — 1–3 sentences: the feature, what's in scope, what's out. When the work is only

a slice of a larger feature, link the big-picture reference (parent story, final-goal/context note, design) so the planner sees how it fits; a self-contained task needs none.

1. Verified codebase facts — the facts confirmed while validating requirements, recorded so

the planner builds on them instead of rediscovering: where the relevant code lives, data shapes, existing analogues, integration points. Byproduct only — never explore beyond what refinement itself needs — and only facts a fresh session would need a search to rediscover. Anchor to paths and identifiers; line numbers are hints — they drift. What is true today, never how to change it. When non-empty, open with one line pinning the commit (short hash, noting uncommitted changes if the tree is dirty) and absolute date, warning the code may have changed since and specifics need re-verifying.

1. Requirements — deduplicated functional + technical list. Tag each item with its ticket source

(e.g. (Description), (Technical Detail), (AC)). Group by area when it aids reading. Cite the concrete file path / identifier inline wherever a requirement touches code; cite a reused pattern as path:line-range.

1. Overrides — where the ticket says one thing and the requirement says another (ticket is

stale, wrong, or self-contradictory). Each entry: what the ticket says, what the code/AC shows, the resulting requirement.

1. Open questions — non-blocking ambiguities, each with your tentative answer and why it's

non-blocking. Blocking questions never appear here.

1. Acceptance criteria — flat, verifiable checklist the implementation must satisfy.

Each requirement is self-contained; user-facing strings that must stay in a given language are quoted verbatim.

Boundaries

• Do not write an implementation plan or describe "how".
• Do not modify any source files. The only file you write is the REQUIREMENTS document.

When done, state — in project-relative paths — that the requirements file is ready, then hand off each next phase as a single copy-pasteable launch command — phase-prefixed session name and prompt combined, so one paste starts the session. Use the launch syntax of the agent tool in use (vendor-agnostic — claude below is only the example), naming the session with the phase prefix plus the requirements file's slug:

claude --name create-manual-test- "/create-manual-test-instructions .REQUIREMENTS.md"   # QA manual test
claude --name create-plan- "/create-implementation-plan .REQUIREMENTS.md"               # Plan phase

The phase prefix (create-plan-, execute-plan-, …) keeps the pipeline phases distinguishable in the session list.

Then offer the plan phase's alternative — clearing the current session instead (vendor-agnostic — /clear below is only the example; use the clear command of the agent tool in use):

OR /clear and run:

/create-implementation-plan .REQUIREMENTS.md
