TRIP Upgrade Mode

You are now in upgrade mode — merging a newer version of the TRIP workflow into this project's existing, customized TRIP skills.

The Problem

Each project's TRIP skills have two interleaved layers:

1. Workflow skeleton — steps, Codex integration, file structure, process flow
2. Project customizations — test commands, checklist sections, version file, technical considerations, guidance sections

A naive copy would destroy layer 2. This skill separates both layers, applies the new skeleton, and re-injects the customizations.

Prerequisites

The user must have copied the new generic TRIP skills into a staging folder before running this skill. Default location: .claude/skills/new-TRIP/

If $ARGUMENTS is provided, treat it as the path to the staging folder. Otherwise use .claude/skills/new-TRIP/.

---

Phase 1: Inventory

1.1 Validate Staging Folder

Confirm the staging folder exists and contains TRIP skills:

ls -R <staging-path>/

If missing or empty, tell the user:

"No staging folder found at <path>. Copy the new TRIP workflow's skills/ folder there first, then re-run."

1.2 Categorize Skills

List all skill folders in both locations:

# Currently installed
ls -d .claude/skills/*/

# New (staging)
ls -d <staging-path>/*/

Categorize each skill into one of:

Category	Meaning	Action
New	Exists in staging only	Copy directly
Removed	Exists in installed only	Warn user, leave in place
Unchanged	Identical in both	Skip
Updated — pure workflow	Changed, but no project customizations	Replace directly
Updated — customized	Changed, AND contains project-specific content	Extract → merge → replace

Pure workflow skills (no project customizations): TRIP-compact, TRIP-hotfix, TRIP-research, TRIP-init, codex-implement, codex-plan-review, codex-code-review

Exception — model defaults: codex-plan-review/scripts/_common.sh holds the per-flow Codex model/effort/service-tier defaults, which the user may have tuned. Before replacing, diff the installed _common.sh against staging — if the model/effort/tier values differ from the generic defaults, carry the user's values into the new file.

Customized skills (have project-specific content): TRIP-1-plan, TRIP-2-implement, TRIP-3-release, TRIP-review, TRIP-test

Renamed in TRIP v2 — when the installed folder uses an old name, treat it as the same skill under its new name (merge into the new name, then delete the old folder):

Installed (old)	Staging (new)
TRIP-3-review	TRIP-review
TRIP-4-test	TRIP-test

TRIP-3-release is new in v2 but its project values (version file, week anchor, tutorial config) are extracted from the old TRIP-2-implement's post-implementation steps — categorize it as customized even though no folder exists yet.

Other non-TRIP skills in staging (e.g. future additions): Treat as new, or as pure workflow if they already exist.

For each skill, diff the installed vs new version to confirm whether it actually changed:

diff -rq .claude/skills/<skill>/ <staging-path>/<skill>/

Phase 2: Extract Project Context

Before touching any installed files, read every customized skill and extract all project-specific values into a context block. This is your safety net — everything here gets re-injected later.

2.1 Read All Installed Skills

Read every file in the installed skills directory that will be affected.

2.2 Extract Customizations

Build a context block by extracting these values from the installed skills:

From TRIP-1-plan/SKILL.md:

• PROJECT_NAME — the text that replaced [PROJECT_NAME] (appears in the # Planning Mode header and **planning mode** for line)
• TECHNICAL_CONSIDERATIONS — the full content of the ## Technical Considerations section in the plan template (everything between ## Technical Considerations and the next ## heading)
• GUIDANCE_SECTIONS — everything after the plan template's closing section that replaced [ADAPT_TO_PROJECT: Guidance Sections] (project-specific per-component guidance at the bottom of the file)
• DOC_IMPACT_CANDIDATES — the candidates list inside the plan template's ## Documentation Impact section, if present (may not exist in pre-v2.5 installs)
• PLAN_PREREQUISITES — any additional living-docs lines in the Prerequisites list beyond ARCHI.md, if present

From TRIP-2-implement/SKILL.md (in v1 installs, the release values below live in its Post-Implementation steps; in v2 installs they live in TRIP-3-release/SKILL.md):

• PROJECT_NAME — (confirm matches TRIP-1-plan)
• VERSION_FILE — the text that replaced [VERSION_FILE] in Step 2
• WEEK_ANCHOR_DATE — the date that replaced [WEEK_ANCHOR_DATE] in Step 1
• TUTORIAL_CONFIG — if tutorials are enabled: the full Tutorial step block with user context. If disabled: note "tutorials disabled"
• LINT_COMMAND — if present (may not exist in older versions)
• TYPECHECK_COMMAND — if present
• TEST_COMMAND — if present

From TRIP-review/SKILL.md — or TRIP-3-review/ in v1 installs (checklist.md if already split):

• REVIEW_CHECKLIST — the full checklist content. In older versions this is inline in SKILL.md. In newer versions it's in checklist.md. Extract it wherever it lives.
• CR_TEMPLATE — if cr-template.md exists, extract it. Otherwise note "no template file — using inline template"

From TRIP-test/SKILL.md — or TRIP-4-test/ in v1 installs:

• TEST_COMMANDS — the full Commands section
• TEST_STRUCTURE — the test structure description
• TESTING_PRIORITIES — the full testing priorities section

2.3 Present Extracted Context

Show the user a summary of what was extracted:

Extracted project context:
- Project name: [name]
- Version file: [path]
- Week anchor: [date]
- Tutorials: [enabled/disabled]
- Test commands: [lint] / [typecheck] / [test]
- Checklist sections: [count] sections ([list names])
- Guidance sections: [count] sections ([list names])
- Technical considerations: [count] items

AskUserQuestion: "Extracted project context looks correct?" Options: "Yes, continue" / "No, let me correct something"

If "No": let the user specify corrections, update the context block.

---

Phase 3: Handle Structural Migrations

Before merging, handle any structural changes between the old and new workflow versions. Read both old and new files to detect what changed structurally.

3.1 Checklist Extraction (TRIP-review)

Old structure (early v1): Checklist inline in TRIP-3-review/SKILL.md New structure (v2): Checklist in separate TRIP-review/checklist.md, template in TRIP-review/cr-template.md (late-v1 installs have these same files under TRIP-3-review/)

If the installed version has the checklist inline in SKILL.md (no separate checklist.md):

1. The extracted REVIEW_CHECKLIST from Phase 2 is the project-customized checklist
2. It will be injected into the new checklist.md in Phase 4

If the installed version already has checklist.md:

1. The extracted content is already in the right format
2. Merge normally in Phase 4

3.2 Codex Integration (TRIP-1-plan, TRIP-2-implement)

Old structure: No Codex review steps New structure: TRIP-1-plan has Step 3 (Codex plan review), TRIP-2-implement has Codex Code Review section

These are pure workflow additions — no project-specific content to migrate. They will be applied from the new template. The only project-specific part is the test commands in TRIP-2-implement's Codex pre-step, which come from the extracted context.

3.3 Codex Skills (codex-plan-review, codex-code-review, codex-implement)

If not installed yet, these are entirely new — copy from staging directly. The review skills reference TRIP-review/checklist.md and TRIP-review/cr-template.md, which will be populated with project content. If already installed (late-v1), replace as pure workflow (see the _common.sh exception in Phase 1.2) — v1 prompt templates point at the old TRIP-3-review/ paths and must be replaced with the v2 versions.

---

Phase 4: Merge & Apply

For each skill, apply the appropriate action from the Phase 1 inventory.

4.1 New Skills — Copy Directly

cp -r <staging-path>/<skill>/ .claude/skills/<skill>/

For skills with state/ directories, ensure .gitignore is in place.

4.2 Pure Workflow Skills — Replace Directly

rm -rf .claude/skills/<skill>/
cp -r <staging-path>/<skill>/ .claude/skills/<skill>/

4.3 Customized Skills — Extract + Merge

For each customized skill, take the new template from staging and inject the extracted project context from Phase 2. This is the core of the upgrade.

General approach: Read the new template file. Find each placeholder or generic section. Replace with the corresponding extracted value. Write the result.

TRIP-1-plan/SKILL.md

1. Start from the new template (staging)
2. Replace [PROJECT_NAME] with extracted PROJECT_NAME
3. Replace the generic ## Technical Considerations block in the plan template with extracted TECHNICAL_CONSIDERATIONS
4. Replace the [ADAPT_TO_PROJECT: Guidance Sections] comment block with extracted GUIDANCE_SECTIONS
5. Resolve the [ADAPT_TO_PROJECT] marker in the ## Documentation Impact section: use extracted DOC_IMPACT_CANDIDATES if present; otherwise build the list from the project's living docs (README, module READMEs, operations/user manuals, reference specs next to the code, contributor guides), one bullet per doc with when it's affected
6. Resolve the [ADAPT_TO_PROJECT] line in the Prerequisites list: use extracted PLAN_PREREQUISITES if present; otherwise list any living docs a plan must respect beyond ARCHI.md, or delete the line if there are none

TRIP-2-implement/SKILL.md

1. Start from the new template (staging)
2. Replace [PROJECT_NAME] with extracted PROJECT_NAME
3. Replace [LINT_COMMAND], [TYPECHECK_COMMAND], [TEST_COMMAND] in the Testing Gate with extracted commands
   • If the old version didn't have Codex review (no test commands extracted), check the old TRIP-4-test for test commands, or ask the user
4. Adapt the Integration impact check comment block to the project's integration/E2E tooling (from the old TRIP-4-test content if present)

TRIP-3-release/SKILL.md (new in v2 — values come from the old TRIP-2)

1. Start from the new template (staging)
2. Replace [PROJECT_NAME] with extracted PROJECT_NAME
3. Replace [VERSION_FILE] with extracted VERSION_FILE
4. Replace [WEEK_ANCHOR_DATE] with extracted WEEK_ANCHOR_DATE
5. Replace [MAIN_BRANCH] with the repo's default branch name
6. Replace the standalone-verification commands with the same extracted lint/typecheck/test commands
7. Handle tutorial config:
   • If tutorials were disabled: remove the [TUTORIAL_STEP] block
   • If tutorials were enabled: replace the [TUTORIAL_STEP] block with extracted TUTORIAL_CONFIG and renumber subsequent steps

TRIP-review/SKILL.md + checklist.md + cr-template.md (was TRIP-3-review in v1)

1. SKILL.md: Start from the new template. Replace [PROJECT_NAME].
2. checklist.md: Start from the new template. Replace the [ADAPT_TO_PROJECT] comment block with the project-specific checklist sections from the extracted REVIEW_CHECKLIST.
   • The new template has generic sections 1-3 (Functional, Code Quality, Architectural) and 4-6 (Error Handling, Security, Performance). The project customization goes between section 3 and 4 (where the comment marker is), and may also modify sections 3-6.
   • If the old checklist had custom sections (numbered 4+), insert them at the [ADAPT_TO_PROJECT] marker and renumber if needed.
   • Preserve the Severity Classification and Approval Gate from the new template unless the project had custom overrides.
3. cr-template.md: Start from the new template. Update the Checklist section names to match the actual sections in the merged checklist.md.

TRIP-test/SKILL.md (was TRIP-4-test in v1)

1. Start from the new template (staging)
2. Replace [PROJECT_NAME] with extracted PROJECT_NAME
3. Replace [TEST_COMMAND_*] placeholders with extracted TEST_COMMANDS
4. Replace test structure placeholder with extracted TEST_STRUCTURE
5. Replace testing priorities placeholder with extracted TESTING_PRIORITIES

4.4 Write All Files

After building all merged content in memory, write every file. Do NOT write partial results — complete the full merge first, then write all at once.

---

Phase 5: Validate

After writing all files, run a validation pass.

5.1 Placeholder Check

Scan all upgraded skill files for leftover placeholders:

grep -rn '\[ADAPT_TO_PROJECT\|\[PROJECT_NAME\]\|\[VERSION_FILE\]\|\[WEEK_ANCHOR_DATE\]\|\[TEST_COMMAND\]\|\[LINT_COMMAND\]\|\[TYPECHECK_COMMAND\]\|\[TUTORIAL_STEP\]\|\[MAIN_BRANCH\]' .claude/skills/TRIP-*/

If any are found, fill them from context or ask the user.

5.2 Cross-Reference Check

• checklist.md section names must match cr-template.md checklist section names
• codex-code-review/prompts/start.tpl and resume.tpl reference .claude/skills/TRIP-review/checklist.md — confirm it exists, and that no template still points at the old TRIP-3-review/ path
• codex-code-review/prompts/synthesize.tpl and codex-code-review/SKILL.md reference .claude/skills/TRIP-review/cr-template.md — confirm it exists
• TRIP-1-plan and TRIP-2-implement reference codex-plan-review/scripts/start.sh and resume.sh; TRIP-2-implement also references codex-implement/scripts/start.sh — confirm they exist

5.3 Present Summary

Show what changed:

Upgrade complete:
- New skills added: [list]
- Skills updated: [list]
- Skills unchanged: [list]
- Project customizations preserved: [list key ones]

AskUserQuestion: "Upgrade applied. Review the changes?" Options: "Looks good" / "Show me the diffs" / "Revert everything"

If "Show me the diffs": run git diff .claude/skills/ and present. If "Revert everything": git checkout -- .claude/skills/

---

Phase 6: Clean Up

After user confirms:

1. Remove the staging folder:

   rm -rf <staging-path>
   

2. Report completion:

   "TRIP workflow upgraded. The staging folder has been removed. You can git diff .claude/skills/ to review all changes before committing."

---

Edge Cases

Old version has no Codex skills at all

This is the most common upgrade path. The Codex skills are "New" — copy directly. The Codex integration in TRIP-1-plan and TRIP-2-implement comes from the new template and needs no project-specific content except test commands.

Old version has inline checklist but no separate files

The structural migration in Phase 3.1 handles this. Extract the custom checklist content from the old SKILL.md, inject into the new checklist.md.

Old version already has the new structure

Everything categorizes as "Unchanged" or minor updates. The merge is trivial.

Project has extra custom skills not in the new workflow

These are "Removed" in the inventory — warn the user but leave them in place. Never delete skills that exist only in the installed version.

Test commands not available anywhere

If the old version predates the Codex review pre-step and TRIP-4-test doesn't have extractable commands, ask the user:

AskUserQuestion: "The new workflow needs lint/typecheck/test commands for Codex code review. What are the commands for this project?" Options: "Let me provide them" (user types commands) / "Skip for now" (leave placeholders)

---

Notes for the Agent

• Read before writing. Read every file you plan to modify. Never write from memory alone.
• Preserve semantics, not bytes. If the old checklist had 10 custom sections, they all need to survive, even if their numbering changes.
• New workflow features get project context. When Codex code review is new, the test commands still need to be filled from the project's existing test setup.
• When in doubt, ask. If you can't confidently extract a customization, show the user the relevant section and ask what to keep.
• Atomic application. Build all merged content before writing any files. If something goes wrong mid-merge, the installed skills should still be intact.
• Never delete user-created files. If the project has extra files in a skill directory (like project-specific fixtures or notes), leave them alone.
