# Validation Report: user-prompt-submit hook wiring (#674)
2+
3+
**Status**: Validated -- Approved for Production
4+
**Date**: 2026-04-29
5+
**Commit**: `2e7deb8e`
6+
**Issue**: Gitea #674 (mirrors GitHub #810 Phase 2)
7+
**Verification Report**: `.docs/verification-phase-674.md`
8+
9+
## Executive Summary
10+
11+
The user-prompt-submit hook wiring feature is validated. Both the Claude Code shell hook and OpenCode plugin correctly invoke `terraphim-agent learn hook --learn-hook-type user-prompt-submit`, and tool-preference corrections are automatically captured from user prompts. All acceptance criteria are met with stakeholder approval.
12+
13+
## End-to-End Test Results
14+
15+
### E2E-001: "use X instead of Y" creates ToolPreference correction
16+
17+
| Step | Action | Expected | Actual |
18+
|------|--------|----------|--------|
19+
| 1 | `echo '{"user_prompt":"use uv instead of pip"}' \| terraphim-agent learn hook --learn-hook-type user-prompt-submit` | Exit 0, one correction file | Exit 0, file created |
20+
| 2 | Check correction file content | `correction_type: tool-preference`, original=`pip`, corrected=`uv` | Confirmed |
21+
| 3 | Verify exactly one file created | 1 file | 1 file |
22+
23+
### E2E-002: "use X not Y" creates ToolPreference correction
24+
25+
| Step | Action | Expected | Actual |
26+
|------|--------|----------|--------|
27+
| 1 | `echo '{"user_prompt":"use cargo not make"}' \| terraphim-agent learn hook --learn-hook-type user-prompt-submit` | Exit 0, one correction file | Exit 0, file created |
28+
| 2 | Check correction file content | `correction_type: tool-preference`, original=`make`, corrected=`cargo` | Confirmed |
29+
30+
### E2E-003: Personal preference does NOT capture
31+
32+
| Step | Action | Expected | Actual |
33+
|------|--------|----------|--------|
34+
| 1 | `echo '{"user_prompt":"I prefer tea over coffee"}' \| terraphim-agent learn hook --learn-hook-type user-prompt-submit` | Exit 0, no correction file | Exit 0, learnings dir empty |
35+
36+
### E2E-004: Shell hook fail-open when agent not installed
37+
38+
| Step | Action | Expected | Actual |
39+
|------|--------|----------|--------|
40+
| 1 | Run shell hook without terraphim-agent in PATH | Warning on stderr, passes input through unchanged | Confirmed (per code review CR-007) |
41+
42+
## Requirements Traceability
43+
44+
| AC ID | Requirement | Evidence | Status |
45+
|-------|-------------|----------|--------|
46+
| AC-1 | `examples/claude-code-hooks/` contains shell hook that pipes JSON into `terraphim-agent learn hook --learn-hook-type user-prompt-submit` | `user-prompt-submit-hook.sh` (40 lines, reviewed CR-006..CR-009) | Accepted |
47+
| AC-2 | OpenCode plugin in `examples/opencode-plugin/` subscribes to user-prompt-submit event | `user-prompt-submit.js` (66 lines, reviewed CR-010..CR-013) + `package.json` | Accepted |
48+
| AC-3 | "use uv instead of pip" creates exactly one correction file under learnings dir | E2E-001 verified: 1 file, `tool-preference`, (pip, uv) | Accepted |
49+
| AC-4 | Unit tests cover 3 positive + 1 negative pattern | 4 integration tests + 7 unit tests + 4 robustness tests (15 total) | Accepted |
50+
| AC-5 | `docs/src/command-rewriting-howto.md` has Phase 2 section | Section 6 "Phase 2: user-prompt-submit wiring" with table, subsections 6.1-6.3 | Accepted |
51+
| AC-6 | `cargo test -p terraphim_agent` passes | 230 lib + 4 integration = 234 passed, 0 failed | Accepted |
52+
| AC-7 | `cargo clippy -p terraphim_agent -- -D warnings` passes | 0 warnings, 0 errors | Accepted |
53+
54+
## Acceptance Interview Summary
55+
56+
**Date**: 2026-04-29
57+
**Stakeholder**: Alex (Product Owner)
58+
59+
### Problem Validation
60+
> "Does this implementation solve the original problem?"
61+
62+
**Answer**: Yes, problem solved. The hooks/plugins wire the entry point correctly and corrections are captured automatically.
63+
64+
### Success Criteria
65+
> "Are you satisfied with the evidence for all 7 acceptance criteria?"
66+
67+
**Answer**: Yes, approve for production. All acceptance criteria met, evidence sufficient.
68+
69+
### Risk Assessment
70+
> "Any deployment concerns with the fail-open design?"
71+
72+
**Answer**: No concerns, safe to deploy. Fail-open design is correct, no risk of user disruption.
73+

## Summary
10+
11+
| Metric | Target | Actual | Status |
12+
|--------|--------|--------|--------|
13+
| Integration tests | 4 scenarios | 4/4 passed | PASS |
14+
| Lib unit tests | No regressions | 230/230 passed | PASS |
15+
| Clippy warnings | 0 | 0 | PASS |
16+
| Format check | Clean | Clean | PASS |
17+
| UBS critical findings | 0 in production code | 0 (2 false positives in test code) | PASS |

## Static Analysis (UBS Scanner)
21+
22+
- **Command**: `ubs crates/terraphim_agent/src/learnings/hook.rs crates/terraphim_agent/tests/user_prompt_submit_tests.rs`
23+
- **Critical findings**: 2 (both false positives -- `panic!` in test code only)
24+
- `hook.rs:712` -- `panic!("Expected Ignored error")` inside `#[cfg(test)] mod tests`
25+
- `user_prompt_submit_tests.rs:16` -- `panic!("cargo build failed: ...")` in test helper
26+
- **Production code critical findings**: 0
27+
- **Assessment**: PASS -- test code panic on setup failure is idiomatic Rust
28+
29+
## Code Review Findings
30+
31+
### hook.rs (`parse_correction_pattern`)
32+
33+
| ID | Finding | Severity | Status |
34+
|----|---------|----------|--------|
35+
| CR-001 | `CorrectionType::Other("user-prompt")` changed to `CorrectionType::ToolPreference` | Improvement | Accepted |
36+
| CR-002 | "use X not Y" pattern added with correct parsing | Feature | Accepted |
37+
| CR-003 | Start-of-string requirement (`use_idx == 0`, `prefer_idx == 0`) prevents false captures like "I prefer tea over coffee" | Bug fix | Accepted |
38+
| CR-004 | UTF-8 safety: `text.to_lowercase().trim_start().find("use ").unwrap() + 4` slices on ASCII keyword boundaries -- safe because "use " and "prefer " are ASCII-only | Low risk | Accepted |
39+
| CR-005 | `process_user_prompt_submit` is fail-open (returns on parse error, never blocks) | Good practice | Accepted |
40+
41+
### user-prompt-submit-hook.sh
42+
43+
| ID | Finding | Severity | Status |
44+
|----|---------|----------|--------|
45+
| CR-006 | `set -euo pipefail` -- strict mode | Good practice | Accepted |
46+
| CR-007 | Fail-open: falls back to `cat` + exit 0 if agent not found | Correct | Accepted |
47+
| CR-008 | Suppresses stderr with `2>/dev/null || true` | Correct | Accepted |
48+
| CR-009 | Always echoes original input after processing | Correct | Accepted |
49+
50+
### user-prompt-submit.js
51+
52+
| ID | Finding | Severity | Status |
53+
|----|---------|----------|--------|
54+
| CR-010 | CommonJS `module.exports` -- matches OpenCode plugin convention | Correct | Accepted |
55+
| CR-011 | Payload normalisation tries `user_prompt`, `prompt`, `message`, string fallback | Defensive | Accepted |
56+
| CR-012 | `child.stdin.write()` + `end()` without error handler on stdin stream | Low risk | Accepted (stdin errors caught by child 'error' event) |
57+
| CR-013 | Never modifies prompt -- returns `input` unchanged | Correct | Accepted |
58+
59+
