Prepare Work Item Brief

prepare_work_item

Read-onlyIdempotent

Generate a risk-aware implementation brief for a GitHub issue from evidence, policy, and history to produce risk, defensive requirements, rollback, observability, and a safe handoff prompt.

Instructions

Generate a risk-aware implementation brief for a GitHub issue. The brief combines bounded Issue/comment evidence, repository policy, confirmed package scripts, related paths, and recent PR history to produce explainable risk, defensive requirements, negative scenarios, rollback, observability, and a safe handoff prompt.

Args:

owner, repo: Repository coordinates.
issueNumber (number): The issue to prepare.
includeRelatedFiles (boolean): Heuristically list related file paths. Default: false. Explicit paths are checked on the default branch, actual adjacent tests are discovered with bounded naming conventions, and CODEOWNERS are attached when available.
includeRecentPRs (boolean): Scan recent merged PRs (up to 20) for ones that touched the related file hints and return up to 5 matches. Requires includeRelatedFiles to find hints to match against — if no hints exist, returns an empty list. Default: false. This opt-in deep scan is bounded but can use up to 61 additional sequential GitHub requests (one PR candidate page plus up to three file pages for each of 20 candidates).
includeDependencies (boolean): Read official blocked-by, blocking, sub-issue, and timeline cross-reference endpoints, capped at 20 items per source. Default: false.
workType (string?): Explicit docs/feature/bugfix/refactor/security/release/infra type.
riskLevel (string?): Explicit minimum low/medium/high/critical risk. Repository policy can raise it.

Returns: Structured risk profile and source evidence, issue/derived acceptance criteria, defensive requirements, negative scenarios, verified repository commands, rollback/observability plans, bounded history metadata, and Markdown safe for agent consumption. Issue and comment text remain untrusted evidence.

Input Schema

Name	Required	Description
`repo`	No	GitHub repo. Falls back to GITHUB_REPO.
`owner`	No	GitHub owner. Falls back to GITHUB_OWNER.
`workType`	No	Explicit work type. When omitted, deterministic issue/policy signals are used.

TDQS

A4.1/5.0

Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Despite annotations already declaring readOnly/idempotent/openWorld, the description adds behavior that structured fields cannot: an explicit request-budget model ('up to 61 additional sequential GitHub requests — one PR candidate page plus up to three file pages for each of 20 candidates'), per-source caps of 20 items, the raise-never-lower policy interaction on riskLevel, and a security warning that issue/comment text is untrusted evidence. These are the exact cost and safety facts an agent needs before enabling expensive flags.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Purpose is front-loaded in the first sentence, followed by a single summary paragraph, then a clean Args list where each entry adds operational detail rather than echoing the schema verbatim. Length is justified by eight parameters with non-obvious cost and dependency semantics; no sentence is filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With 8 parameters, an output schema, and four annotations, the burden on the description is moderate, and it discharges most of it: defaults, flag dependencies, request budgets, caps, and untrusted-content handling are all present, and the return description is redundant against the existing output schema but harmless. What is missing is the routing context — which sibling tool to pick instead — leaving a small completeness gap.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is already 100%, so the baseline is 3, but the description meaningfully exceeds the schema: it explains what includeRelatedFiles actually does (default-branch path checks, adjacent-test discovery via bounded naming conventions, CODEOWNERS attachment), the includeRecentPRs→includeRelatedFiles dependency, and the 20-item/61-request cost envelope. Only riskLevel and workType mostly restate their schema descriptions, which keeps this from a 5.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

Opens with a specific verb+resource: 'Generate a risk-aware implementation brief for a GitHub issue', and enumerates the concrete artifacts produced (risk profile, defensive requirements, rollback, handoff prompt). An agent can tell it is distinct from generic evidence tools, but the description never names which sibling (plan_from_context, sdlc_evidence_packet, agent_handoff_packet) it replaces or complements, so sibling differentiation is left to inference.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Usage is only implied by the shapes of the opt-in flags: the description explains that includeRecentPRs depends on includeRelatedFiles and returns empty without hints, which is genuinely useful gating guidance. However there is no statement of when to reach for this tool versus the several overlapping planning/evidence siblings, and no prerequisites or exclusions are given, so guidance sits at the 'implied usage' level.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
