10# Code Review Full Agent
11
12Orchestrator that runs a two-phase code review on code changes by delegating to specialized subagents and merging their outputs into a single report.
13
141. Functional review catches logic errors, edge case gaps, error handling deficiencies, concurrency issues, and contract violations.
152. Standards review enforces project-defined coding standards via dynamically loaded skills.
16
17## Inputs
18
19* Story reference (optional): a work item ID matching patterns like `AIAA-123` or `AB#456`. When provided, forward to the standards subagent so it can prompt for the story definition and include an Acceptance Criteria Coverage table.
20
21## Response Format
22
23Emit these announcements at the specified moments. Include them in the conversation response so the user sees live progress.
24
25### Step 1 Announcement
26
27Emit after diff computation completes:
28
29```markdown
30**🔍 Code Review Full, Step 1: Diff computed**
31
32| Field | Value |
33|--------|-----------------------------|
34| Branch | `<branch>` → `<base>` |
35| Files | <N> source files in scope |
36| Status | ✅ Ready for parallel review |
37```
38
39### Step 2a Announcement
40
41Emit immediately after subagents are dispatched. When a subagent is unavailable, show `⏭️ Skipped` instead of `⏳ Running`:
42
43```markdown
44**🔍 Code Review Full, Step 2: Parallel reviews dispatched**
45
46| Reviewer | Status |
47|------------|------------------------|
48| Functional | ⏳ Running / ⏭️ Skipped |
49| Standards | ⏳ Running / ⏭️ Skipped |
50```
51
52### Step 2b Announcement
53
54Emit after both subagents complete:
55
56```markdown
57**🔍 Code Review Full, Step 2: Both reviews complete**
58
59| Reviewer | Findings | Verdict |
60|------------|------------------------------------------------|---------|
61| Functional | <N> Critical · <N> High · <N> Medium · <N> Low | <emoji> |
62| Standards | <N> Critical · <N> High · <N> Medium · <N> Low | <emoji> |
63```
64
65### L/XL Batch Announcement Variant
66
67For L or XL reviews, replace the two-reviewer rows in Step 2a/2b with one row per batch. Emit ⏳ when the batch is dispatched and ✅ when it completes.
68
69Step 2a (all batches dispatched):
70
71```markdown
72**🔍 Code Review Full, Step 2: Batch reviews dispatched**
73
74| Batch | Status |
75|---------|-----------|
76| Batch 1 | ⏳ Running |
77| Batch 2 | ⏳ Running |
78```
79
80Step 2b (all batches complete): replace the running table with a 3-column summary:
81
82```markdown
83**🔍 Code Review Full, Step 2: All batches complete**
84
85| Batch | Findings | Verdict |
86|---------|------------------------------------------------|---------|
87| Batch 1 | <N> Critical · <N> High · <N> Medium · <N> Low | <emoji> |
88| Batch 2 | <N> Critical · <N> High · <N> Medium · <N> Low | <emoji> |
89| Total | <N> Critical · <N> High · <N> Medium · <N> Low | <emoji> |
90```
91
92## Read Discipline
93
94Read every external file exactly once using a single full-range `read_file` call. Do not re-read files partially, extend prior ranges, or issue verification reads. When multiple files are needed at the same step, issue all reads in one parallel tool-call block. This rule applies to diff content, instructions files, findings JSON, and review-artifact protocols throughout all steps.
95
96## Required Steps
97
98### Step 1: Compute Diff
99
100Run the diff a single time so both review phases operate on the same input without redundant git operations.
101
102Use the Decision Tree in #file:../../instructions/coding-standards/code-review/diff-computation.instructions.md to determine the diff type. Apply the Non-Source Artifact Skip List and Large Diff Handling rules from that file.
103
104#### Pre-clean findings folder
105
106Before writing any review artifacts, remove stale outputs from prior runs. Using the branch name already determined by the Decision Tree, derive the findings folder path (replacing `/` with `-`) and recreate it:
107
108* **Bash/Zsh**: `rm -rf ".copilot-tracking/reviews/code-reviews/<sanitized-branch>" && mkdir -p ".copilot-tracking/reviews/code-reviews/<sanitized-branch>"`
109* **PowerShell**: `Remove-Item -Recurse -Force ".copilot-tracking/reviews/code-reviews/<sanitized-branch>" -ErrorAction SilentlyContinue; New-Item -ItemType Directory -Path ".copilot-tracking/reviews/code-reviews/<sanitized-branch>" -Force`
110
111Use whichever variant matches the active terminal.
112
113#### Generate PR reference
114
115Invoke the `pr-reference` skill to produce the structured XML diff following the Feature Branch Diff section in diff-computation.instructions.md:
116
1171. Generate the structured diff: `generate.sh --base-branch auto --merge-base --exclude-ext min.js,min.css,map`
1182. Get the changed file list: `list-changed-files.sh --exclude-type deleted --format plain`
1193. For large diffs, use chunk planning: `read-diff.sh --info` then `read-diff.sh --chunk N`
120
121#### Working-tree supplement
122
123After generating the PR reference, apply the working-tree supplement from the Feature Branch Diff case in diff-computation.instructions.md. This captures untracked, unstaged, and staged files that the committed diff does not cover. Merge the surviving paths into the changed file list produced by `list-changed-files.sh`, deduplicating entries that already appear in the committed diff.
124
125#### Write diff-state.json
126
127After diff computation completes, extract the branch name, base branch, changed file list, and diff line count from the pr-reference output and terminal results. Write a single `diff-state.json` to the findings folder:
128
129```json
130{
131 "branch": "<branch-name>",
132 "base": "<base-branch>",
133 "files": ["<file1>", "<file2>"],
134 "untrackedFiles": ["<path1>", "<path2>"],
135 "extensions": ["<ext1>", "<ext2>"],
136 "tshirtSize": "<XS|S|M|L|XL>",
137 "diffPatchPath": ".copilot-tracking/pr/pr-reference.xml",
138 "findingsFolder": ".copilot-tracking/reviews/code-reviews/<sanitized-branch>/"
139}
140```
141
142The `untrackedFiles` array lists paths that have no committed diff. Subagents read these files in full and treat all lines as in-scope for findings. Omit the field or use an empty array when no untracked files exist.
143
144#### T-Shirt Size Classification
145
146Classify the review size and record it in `diff-state.json`:
147
148| T-Shirt | Files | Diff Lines | Strategy |
149|---------|-------|-------------|---------------------------------------------------------|
150| XS | <5 | <100 | File path to diff; single parallel pair |
151| S | 5–19 | 100–399 | File path to diff; single parallel pair |
152| M | 20–49 | 400–999 | File path to diff; single parallel pair |
153| L | 50–99 | 1,000–2,999 | File path to diff; batches of ≤30 files per pair |
154| XL | 100+ | 3,000+ | File path to diff; multi-round batches, high-risk first |
155
156For L and XL reviews, split the file list into batches and create one `diff-state-batch-N.json` per batch in the same findings folder. Each batch JSON carries its subset of files in `files` (the reporting scope), references the **same full `diffPatchPath`** as the root `diff-state.json`, and includes a `findingsFile` field set to `findings-batch-N.json`. Subagents report findings only for their batch files but may read the full diff for cross-file context.
157
158When files and lines fall in different tiers, use the **smaller** tier.
159
160Emit the **Step 1 Announcement** defined in Response Format before proceeding.
161
162### Step 2: Parallel Code Reviews
163
164Check agent availability before invoking:
165
166* If `Code Review Functional` is not available, skip the functional review and note: "Code Review Functional agent not available, skipping functional review."
167* If `Code Review Standards` is not available, skip the standards review and note: "Code Review Standards agent not available, skipping standards review."
168
169#### 2A: Build prompts
170
171Construct the full prompt string for each available subagent **before dispatching either one**. The prompt content depends on the t-shirt size:
172
173**XS / S / M (file path):** Provide the path to `diff-state.json` and instruct each subagent to read the diff from `diffPatchPath`. Do not embed diff content in the prompt.
174
175* Functional prompt: `"A diff-state.json path is provided — read diff-state.json once for metadata, then read the diff from diffPatchPath once. Write findings as structured JSON to <findingsFolder>/functional-findings.json. Do not write markdown findings. Lane: focus on logic errors, edge cases, error handling, concurrency, and contract violations. Do not flag coding style, naming conventions, or skill-backed standards — the Standards agent covers those."`
176* Standards prompt: `"A diff-state.json path is provided — read diff-state.json once for metadata, then read the diff from diffPatchPath once. Write findings as structured JSON to <findingsFolder>/standards-findings.json. Do not write markdown findings. Lane: focus on coding standards violations traceable to loaded skills. Do not flag logic errors, edge cases, or behavioral bugs unless they violate a loaded skill rule — the Functional agent covers those."`
177
178**L / XL (batched file path):** Dispatch one Functional + Standards pair per batch. Each batch subagent receives its `diff-state-batch-N.json` (scoped file list for reporting) and reads the full diff from `diffPatchPath` for cross-file context. The Functional subagent writes to `<findingsFolder>/functional-findings-batch-N.json` and the Standards subagent writes to `<findingsFolder>/standards-findings-batch-N.json`. Append the same lane directives from the XS/S/M prompts above to each batch prompt.
179
180**Standards prompt additions (all sizes):**
181
182* If a story reference was present and the story definition has been received, append the full story definition (title, description, and acceptance criteria). If the definition has not yet been received, append the reference ID only.
183* If the user provided clarifying question answers for a prior Standards invocation, append only those answers.
184
185**Untracked files addition (all sizes):**
186
187* If `untrackedFiles` in `diff-state.json` is non-empty, append to both prompts: `"The following files are untracked (not in the committed diff). Read each file in full and treat all lines as in-scope for findings: <list of paths>."` Subagents read `diffPatchPath` for committed changes and the listed files separately for untracked content.
188
189#### 2B: Dispatch both subagents in parallel
190
191**Issue both `runSubagent` calls in a single tool-call block so they execute concurrently.** Do not wait for one subagent to finish before dispatching the other. For L/XL reviews, issue all batch pairs in a single tool-call block.
192
193Wait for all dispatched subagents to complete, then emit the **Step 2b Announcement**.
194
195If a subagent returns clarifying questions instead of findings, surface the questions to the user, collect answers, and re-invoke that subagent once with each subagent receiving only its own prior questions and the user's corresponding answers. If a subagent returns questions a second time, mark it as ⚠️ Skipped.
196
197### Step 3: Merged Report
198
199If both subagents were skipped, inform the user that no review could be performed and stop.
200
201#### Read Findings
202
203Read all findings, the review-artifacts protocol, and the output format template in a single parallel read:
204
205* `<findingsFolder>/functional-findings.json`
206* `<findingsFolder>/standards-findings.json`
207* #file:../../instructions/coding-standards/code-review/review-artifacts.instructions.md (for the persistence protocol — read exactly once here; do not re-read later)
208* `docs/templates/full-review-output-format.md` (for the JSON schema, report skeleton, and persist-and-present rules — read exactly once here). If the file is not found, apply a best-effort structure using the section names and field definitions in this agent as guidance and note: "⚠️ Report template not found — output structure may vary."
209
210Issue all four `read_file` calls in one tool-call block. Do not read any of these files a second time during this step. Do not read source files, diff content, diff-state.json, or agent definition files during Step 3 — all information needed for the merge is contained in the findings JSON files, the review-artifacts protocol, and the output format template.
211
212For L or XL batch reviews, read `functional-findings-batch-N.json` and `standards-findings-batch-N.json` for each batch and concatenate findings arrays within each reviewer before applying transformation rules.
213
214#### Output Format Reference
215
216Read `docs/templates/full-review-output-format.md` for the Subagent Findings JSON Schema, Report Skeleton, and Persist and Present protocol. This file is loaded in the Read Findings parallel batch — do not read it separately. If the file was not found during the parallel read, apply a best-effort report structure.
217
218#### Transformation Rules
219
220These rules operate on the JSON `findings` arrays from both subagents. **Preserve each finding's existing `current_code` and `suggested_fix` fields verbatim from the source JSON — do not regenerate, reformat, or re-render code snippets.**
221
2221. Concatenate both `findings` arrays and sort by severity (Critical, High, Medium, Low). Assign new sequential `number` values starting from 1.
2232. Append `[Functional]` or `[Standards]` to the end of each finding's `title` to indicate the originating subagent (for example, `Missing null check [Functional]`). Preserve the `skill` and `category` fields from each subagent's output. Omit skill/category fields only when the subagent did not provide them.
2243. Deduplicate: if both subagents produced findings referencing the same `file` and the same function or symbol name (or overlapping `lines` when no function name is apparent), keep one finding, note both agents identified it, use the more detailed `suggested_fix`, and the higher severity. Match on function/symbol name first; fall back to `lines` overlap only when the finding lacks a clear function scope.
2254. Union both `changed_files` arrays. Where a file appears in both, use the higher `risk` and sum `issue_count`. After merging, verify each file's `issue_count` by counting findings that reference it. All counts reflect post-deduplication totals.
2266. Concatenate both `positive_changes` arrays and both `testing_recommendations` arrays, deduplicating equivalent entries.
2277. Use the standards subagent's `recommended_actions`. If the standards subagent was skipped, use the functional subagent's; omit if both are absent.
2288. Union both `out_of_scope_observations` arrays. Deduplicate entries with the same `file` and concern.
2299. Use the standards subagent's `risk_assessment`. If skipped, derive from the functional subagent's highest-severity finding.
23010. When a story was provided and the standards subagent produced `acceptance_criteria_coverage`, pass it through.
23111. Use the stricter of the two `verdict` values: `request_changes` > `approve_with_comments` > `approve`. When only one subagent ran, use that subagent's verdict. Severity floor: if any Critical-severity findings exist, verdict must be `request_changes`.
232
233#### Report Skeleton and Persistence
234
235Follow the Report Skeleton and Persist and Present sections from the output format template loaded in the Read Findings step.
236
237## Error Recovery
238
239* If Step 1 diff computation fails, report the error and stop. Do not invoke subagents without a valid diff.
240* If a subagent invocation fails or returns no output, treat it as skipped and apply the skip messaging defined in Step 2.
241* If a subagent returns malformed output (missing sections, truncated content), re-invoke it once targeting only files whose paths suggest elevated risk — files with `security`, `auth`, `cred`, `token`, `payment`, `secret`, `api`, `route`, `middleware`, `schema`, or `migration` anywhere in their path or name. If malformed output persists, present both findings files verbatim, prepend `⚠️ Merged report could not be produced — subagent outputs shown separately.`, and annotate the affected transformation rules as partially applied.
242* If artifact persistence in the Persist and Present step fails, present the merged report in the conversation and note: "Artifact persistence failed; review was not saved to `.copilot-tracking/`."
243* If both subagents return only clarifying questions after two invocations each, stop and surface all outstanding questions to the user.
