Implement scenario sc-taskify-complete-task. Your working directory is /workspace. The repo is cloned on the default branch.

Follow these instructions:

Memory sandbox implementation rules

Steps

Create the implement branch: git checkout -b implement/sc-taskify-complete-task
Read scenario from pre-injected graph in prompt.
Write code files with workspace_write/workspace_edit.
Commit: git add -A && git commit -m "implement: sc-taskify-complete-task"
Push: flow git-proxy git push --force-with-lease origin implement/sc-taskify-complete-task — NEVER use bare git push, always flow git-proxy git push.
Open PR using the exact command from the session context block — NEVER use bare gh pr create, always flow git-proxy gh pr create. If it fails because a PR already exists, ignore the error and stop.
Stop.

CRITICAL: Never use bare git push or gh commands

All remote git and gh operations MUST go through flow git-proxy. Bare git push and gh pr create will fail — the sandbox has no GitHub credentials.

CRITICAL: Never modify go.mod

Do not change the module name, Go version, or any dependency in go.mod. If a package is missing, add it with go get, never by hand-editing go.mod.

CRITICAL: Never write line-number prefixes into files

When reading a file, the tool returns lines prefixed with numbers (e.g. 1 module foo). These prefixes are display artifacts — never copy them into file content. Write only the raw content.

HTTP handler response bodies

When a scenario step says the client "receives" a resource or field, the handler must encode and return that resource as JSON:

w.Header().Set("Content-Type", "application/json")
json.NewEncoder(w).Encode(result)

Never return 200 with an empty body when the scenario describes a response payload.

Session context (do not rediscover — use these values directly)

Scenario key: sc-taskify-complete-task
Implement branch: implement/sc-taskify-complete-task (create with git checkout -b implement/sc-taskify-complete-task before writing any files)
Plan branch: plan/main
GitHub repo: https://github.com/emergent-company/taskify-api

Project tech stack

Tech stack: Go 1.22, PostgreSQL ($1/$2 placeholders), standard net/http (no framework), sqlc for DB access. Service methods must accept context.Context as first argument.

Project patterns

[pat-db-postgres] db/: PostgreSQL. Use $1, $2 positional placeholders. Never use ?. Driver: lib/pq or pgx.
[pat-service-context] service/: Service methods must accept context.Context as first argument.

Follow these instructions:

Ultra mode. Abbreviate everything. Arrows for causality (X → Y). Drop articles/conjunctions/filler. One word when sufficient. Technical terms exact. Code unchanged.

Pattern: [thing] [action] [reason]. [next step].

Code/commits/PRs: write normal.

The scenario sc-taskify-complete-task has been implemented.

Created db/migrations/001_create_tasks.sql for the tasks table.
Created db/queries/tasks.sql for the CompleteTask SQL query.
Implemented service/tasks.go with CompleteTask business logic.
Implemented handler/tasks.go with HandleCompleteTask HTTP handler.
Updated main.go to wire up the new handler and service.
Committed and pushed the changes, and opened a pull request.
