Shiplog
The captain's log for your codebase. Every decision, discovery, and change logged as you ship code.
Use GitHub as a complete knowledge graph where every brainstorm, commit, review, and decision is traceable. This skill orchestrates existing skills and references; it defines when and how to invoke them and what documentation protocol to follow.
Core Principle
Nothing gets lost. Every brainstorm becomes an issue. Every issue drives a branch. Every branch produces a PR. Every PR is a timeline of the entire journey. Git becomes the uber-memory.
Golden-Path Walkthrough
A complete issue-to-merge example using a concrete fake issue #999. Follow this sequence and every artifact produced will pass the acceptance checklists in commands/shiplog/*.md.
Step 1 — Plan Capture (/shiplog plan)
A brainstorm produces: "Add rate-limit headers to the API so clients can back off intelligently." Load commands/shiplog/plan.md and create the issue:
gh issue create \
--title "[shiplog/plan] Add rate-limit headers to API" \
--label "shiplog/plan" \
--body-file .tmp-plan.md
Issue body (excerpt):
<!-- shiplog:
kind: state
status: open
phase: 1
readiness: ready
task_count: 2
tasks_complete: 0
max_tier: tier-2
updated_at: 2026-04-18T10:00:00Z
-->
## Tasks
- [ ] **T1: Add X-RateLimit-* headers to response middleware** `[tier-2]`
- **What:** Inject X-RateLimit-Limit, X-RateLimit-Remaining, X-RateLimit-Reset on every API response.
- **Verification:** curl the endpoint; confirm all three headers are present.
- [ ] **T2: Document header semantics in API reference** `[tier-2]`
- **What:** Add a "Rate Limiting" section to docs/api-reference.md.
- **Verification:** Section exists and matches header values in integration test.
Authored-by: claude/sonnet-4.6 (claude-code)
Apply lifecycle label: gh issue edit 999 --add-label "shiplog/ready"
Step 2 — Branch Setup (/shiplog start)
Load commands/shiplog/start.md. Create the branch from the default branch tip (substitute your repo's default branch, e.g. main or master):
git fetch origin <default-branch>
git checkout -b issue/999-rate-limit-headers origin/<default-branch>
Swap label and update envelope:
gh issue edit 999 --remove-label "shiplog/ready" --add-label "shiplog/in-progress"
Post session-start comment:
[shiplog/session-start] #999: Starting work
**Branch:** `issue/999-rate-limit-headers`
**Starting tasks:** T1, T2
**Plan:** Add headers in middleware (T1) then document (T2).
Authored-by: claude/sonnet-4.6 (claude-code)
Step 3 — Commit Context (/shiplog commit)
After implementing T1, load commands/shiplog/commit.md and commit:
git add src/middleware/rate_limit.ts
git commit -F .tmp-commit-msg.md
Post commit-note on the issue:
[shiplog/commit-note] #999: a1b2c3d feat(#999/T1): add X-RateLimit-* headers
**What:** Middleware now injects X-RateLimit-Limit, -Remaining, and -Reset.
**Why:** Clients need these to implement back-off without polling.
**Verification:** curl localhost:3000/api/health — all three headers present.
Authored-by: claude/sonnet-4.6 (claude-code)
Repeat for T2 commit (docs(#999/T2): document rate-limit headers in API reference).
Step 4 — PR Timeline (/shiplog pr)
Load commands/shiplog/pr.md. Push and create the PR:
git push -u origin issue/999-rate-limit-headers
gh pr create \
--title "feat(#999): add rate-limit headers to API" \
--label "shiplog/history" \
--label "shiplog/issue-driven" \
--body-file .tmp-pr-body.md
PR body includes: envelope (kind: history), summary, Closes #999, Journey Timeline with both commits, Verification checklist, Reviews placeholder, and sig block:
Authored-by: claude/sonnet-4.6 (claude-code)
Last-code-by: claude/sonnet-4.6 (claude-code)
*Captain's log — PR timeline by **shiplog***
Transition issue label:
gh issue edit 999 --remove-label "shiplog/in-progress" --add-label "shiplog/needs-review"
Step 5 — Cross-Model Review (/shiplog review)
A different model (e.g., openai/gpt-5.4 (codex)) loads commands/shiplog/review.md, reads the diff, and posts the signed review comment on the PR:
[shiplog/review-handoff] #999: Review of PR #<PR>
Middleware approach is correct. Headers match RFC 6585 semantics.
Reviewed-by: openai/gpt-5.4 (codex, effort: high)
Disposition: approve
Scope: full diff
Follow-ups: none
The reviewer then updates the PR body review snapshot in place:
Current state: approved
Last reviewed by: openai/gpt-5.4 (codex, effort: high)
Last reviewed at: 2026-04-18T15:00:00Z
Reviewed commit: a1b2c3d
Source artifact: <URL to review comment>
Needs re-review since: —
Step 6 — Merge
Cross-model gate is satisfied (Last-code-by: claude/sonnet-4.6 ≠ Reviewed-by: openai/gpt-5.4). Merge the PR. Remove all lifecycle labels from issue #999. GitHub closes #999 automatically via Closes #999.
When This Skill Activates
User-invocable: /shiplog, /shiplog models, /shiplog <phase>
/shiplog models: Re-runs the routing setup prompt. See references/model-routing.md.
Auto-activate when ANY of these occur:
- User says "let's plan", "let's brainstorm", or "let's design"
- User explicitly requests traceability or knowledge-graph tracking
- Creating a new issue or PR with intent to document decisions
- Mid-work discovery requiring a new issue or stacked PR
- User asks "where did we decide X?" or "what's the status of Y?"
- Resuming work on an existing issue or PR
- Applying review feedback, fixing review findings, or addressing request-changes dispositions
- User references an issue or PR by number
- Issue or PR body footer contains
Managed by **shiplog** (recognition trigger — do not add this footer proactively)
Do NOT auto-activate for:
- Generic coding requests that do not need traceability
- Simple bug fixes or refactors that do not need durable workflow history
- Work where a more specific skill is the better fit
Verb Grid
Each /shiplog <phase> slash command maps to one sub-skill file. Load the file for that phase — it owns policy, templates, and acceptance checklist.
| Command | What it does | Sub-skill |
|---|
/shiplog plan | Capture a brainstorm as a GitHub planning issue with envelope + task contracts | commands/shiplog/plan.md |
/shiplog start | Create a branch from an issue, swap lifecycle labels, post session-start comment | commands/shiplog/start.md |
/shiplog hunt | Triage open issues and PRs; rank by readiness; detect gate-satisfying reviews | commands/shiplog/hunt.md |
/shiplog commit | Stage and commit with ID-first format; post commit-note comment for significant commits | commands/shiplog/commit.md |
/shiplog pr | Push branch, create PR with journey timeline body, transition issue label | commands/shiplog/pr.md |
/shiplog review | Perform cross-model review; post signed comment; update PR body review snapshot | commands/shiplog/review.md |
/shiplog lookup | Search issues, PRs, and git log by #ID or keyword; return compact table first | commands/shiplog/lookup.md |
/shiplog resume | Re-orient to current branch; detect issue number; post session-resume comment | commands/shiplog/resume.md |
/shiplog models: Re-runs the model-routing setup prompt. See references/model-routing.md.
Canonical Kind → Tag → Label Map
kind: in envelope YAML is the source of truth. Title tags ([shiplog/<tag>]) and GitHub labels (shiplog/<label>) are derived views on kind:. When a new artifact kind is defined, it is added here once and all three surfaces are updated together.
kind: (envelope) | Title tag [shiplog/<tag>] | GitHub label shiplog/<label> | Description |
|---|
state | plan, session-start, session-resume, milestone, discovery, implementation-issue | plan (planning issues) | Current status snapshot of an issue or PR |
handoff | session-start, review-handoff | — | Context transfer between tiers, tools, or sessions |
verification | commit-note, review-handoff, verification | verification | Evidence of testing, review, or quality check |
commit-note | commit-note | — | Reasoning behind a specific commit |
review-handoff | review-handoff | — | Review request or review completion artifact |
amendment | amendment | — | Correction or clarification for an existing signed artifact |
blocker | blocker | blocker | Something preventing progress |
history | history | history | Retrospective summary for knowledge retrieval |
Lifecycle labels (shiplog/ready, shiplog/in-progress, shiplog/needs-review) are not tied to an artifact kind:. They track issue/PR workflow state and are mutually exclusive. Apply them per the Triage Field Maintenance table below.
Aspect labels (shiplog/discovery, shiplog/stacked, shiplog/issue-driven) classify the relationship between artifacts, not their content kind. They may coexist with lifecycle labels.
For the full label set, color codes, and bootstrap CLI snippets, see references/labels.md (which cross-references this table as its canonical kind source).
ID-First Naming Convention
All artifacts use #ID as the primary key for fast, token-efficient retrieval.
Semantic tag vocabulary for user-facing headings: plan, session-start, session-resume, commit-note, discovery, blocker, implementation-issue, handoff, review-handoff, history, amendment, milestone, and verification. Format: [shiplog/<tag>] <human title>. See the Canonical Kind → Tag → Label Map section for the authoritative mapping.
| Artifact | Convention | Example |
|---|
| Branch | issue/<id>-<slug> | issue/42-auth-middleware |
| Commit | <type>(#<id>): <msg> | feat(#42): add JWT validation |
| Commit (task) | <type>(#<id>/<Tn>): <msg> | feat(#42/T2): add middleware chain |
| PR title | <type>(#<id>): <msg> | feat(#42): add auth middleware |
| PR body (closes) | Closes #<id> | Closes #42 |
| PR body (partial) | Addresses #<id> (completes ...) | Addresses #42 (completes T1, T2) |
| Task in issue | - [ ] **T<n>: Title** [tier-N] | - [ ] **T1: Add JWT** [tier-3] |
| Timeline comment | [shiplog/<kind>] #<id>: ... | [shiplog/discovery] #42: race condition |
| Stacked branch | issue/<new-id>-<slug> | issue/43-fix-race-condition |
| Stacked PR title | <type>(#<new-id>): ... [stack: #<parent>] | fix(#43): race cond [stack: #42] |
| Memory entry | #<id>: <decision> | #42: chose JWT over sessions |
Task IDs: Tasks carry local IDs (T1, T2, ...) scoped to the issue. Commits use #<id>/<Tn>.
Retrieval: gh issue list --search "#42" | git log --grep="#42" | git log --grep="#42/T1" | gh pr list --search "#42"
Envelope Schema and Triage Fields
Issue and PR envelopes use <!-- shiplog: ... --> HTML comment blocks. The full field schema and triage field derivation rule live in references/artifact-envelopes.md §1. Summary of triage fields:
| Field | Derived from | Hand-written? |
|---|
task_count | Count of - [ ] + - [x] lines | No — derived |
tasks_complete | Count of - [x] lines | No — derived |
max_tier | Highest [tier-N] among unchecked tasks | No — derived |
readiness | Workflow intent | Yes |
Triage field maintenance: keep envelope triage fields current on each lifecycle event. See the Triage Field Maintenance table below. Derivation rule is in references/artifact-envelopes.md §1.
Triage Field Maintenance
Issue envelope triage fields (readiness, task_count, tasks_complete, max_tier) and lifecycle labels must be kept current so triage scans produce accurate results.
| Event | Envelope update | Label update |
|---|
| Issue created (Phase 1) | Set all four triage fields at creation (task_count, tasks_complete, max_tier from derivation rule; readiness by intent) | Apply shiplog/ready if tasks are scoped and no blockers |
| Branch created (Phase 2) | Set readiness: in-progress | Replace lifecycle label with shiplog/in-progress |
| Task checked off (Phase 4) | Recompute tasks_complete and max_tier from body (derivation rule) | - |
| All tasks complete | Set readiness: done; max_tier will be empty per derivation rule | - |
| Blocker found (Phase 3) | Set readiness: blocked | Add shiplog/blocker |
| Blocker cleared | Restore previous readiness (in-progress or ready) | Remove shiplog/blocker |
| PR created (Phase 5) | Set readiness: done if all tasks shipped | Replace lifecycle label with shiplog/needs-review |
| PR merged and issue closed | - | Remove all lifecycle labels |
Derived fields: task_count, tasks_complete, and max_tier are computed from the issue body task list (counted - [ ] / - [x] lines and highest [tier-N] among unchecked tasks). See the derivation rule in references/artifact-envelopes.md §1 "Triage field derivation". Only readiness is hand-written.
Edit the issue body in place when these fields change. Triage metadata is derived state, so refreshing it does not require Updated-by: provenance.
Agent Identity Signing
Every shiplog artifact (comments, PR bodies, review sign-offs) must carry a provenance signature in the canonical format:
<role>: <family>/<version> (<tool>[, <qualifier>])
Signature field reference
| Field | Values | Examples |
|---|
role | Authored-by, Updated-by, Reviewed-by, or Last-code-by | — |
family | Provider name, lowercase | claude, openai, google |
version | Model identifier | opus-4.6, sonnet-4.6, gpt-5.4 |
tool | Runtime environment, lowercase | claude-code, codex, cursor |
qualifier | Optional metadata string; may be compound when needed | effort: high, orchestrator, sub-agent: reviewer, effort: high; orchestrator |
Searching: Authored-by: → original authorship. Updated-by: → later material editors. Reviewed-by: → review artifacts. Last-code-by: → most recent code author on a PR branch. claude/ → all Claude artifacts. (codex → all Codex artifacts.
Model detection per tool
| Tool | Source | Example signature |
|---|
| Claude Code | System prompt model name | claude/opus-4.6 (claude-code) |
| Codex | ~/.codex/config.toml model + model_reasoning_effort | openai/gpt-5.4 (codex, effort: high) |
| Cursor | System prompt model identifier | claude/opus-4.6 (cursor) |
| Other | Best available model identifier | <family>/<version> (<tool>) |
Orchestration role qualifiers
When an artifact is emitted as part of a multi-lane flow, qualifiers carry orchestration role information:
orchestrator — the current actor dispatched or collected delegated lanessub-agent: reviewer — delegated reviewer lanesub-agent: verifier — delegated closure verifier lanesub-agent: implementation — delegated implementation lane
Examples:
Authored-by: openai/gpt-5.4 (codex, effort: high; orchestrator)Reviewed-by: claude/opus-4.6 (claude-code, sub-agent: reviewer)Authored-by: openai/gpt-5.4 (codex, sub-agent: verifier)
Correction rule
If a shiplog artifact carries an incorrect or incomplete signature, correct it in place when the platform allows editing. Otherwise post an immediate follow-up correction.
Edit provenance rules
Authored-by: records the original author of an artifact body.Updated-by: records a later model or human who materially edits that same artifact body. Preserve the original Authored-by: line and append a new Updated-by: line for each material edit, newest last.Reviewed-by: is review-only. Do not use it for authorship or edit attribution.- Updating a PR body's review snapshot after publishing a signed review comment or after pushing code that makes a prior review stale counts as a material edit.
- A material edit changes meaning, facts, scope, requirements, acceptance criteria, verification results, review disposition, or a handoff contract. Typos, formatting cleanups, and link-only fixes are cosmetic and do not need
Updated-by:.
Code provenance: Last-code-by:
Last-code-by: tracks which model most recently pushed code to a PR branch. It is distinct from artifact provenance fields.
| Field | Tracks | Updated when |
|---|
Authored-by: | Original artifact text author | Artifact is created |
Updated-by: | Later artifact text editor | Artifact body is materially edited |
Reviewed-by: | Review author | Review sign-off is posted |
Last-code-by: | Most recent code author | Code is pushed to the PR branch |
When to set Last-code-by::
- On PR creation: set in the PR body sign-off block (the creating model is the initial code author).
- After pushing code to an existing PR branch: update via
gh pr edit.
- After review-driven code changes: the reviewer who pushes fixes becomes
Last-code-by:.
When NOT to update Last-code-by:: reviewing without pushing code; editing the PR body text without commits; rebasing or force-pushing without new code changes.
Why this field exists: The multi-model review gate must know who last changed the code to determine whether a review is cross-model (gate-satisfying) or same-model (non-gate-satisfying). Without Last-code-by:, consumers fall back to git commit forensics.
Fallback chain for review gating:
Last-code-by: in the PR body (authoritative)Updated-by: in the PR body (approximate)Authored-by: in the PR body (original author — may be stale)- Git commit author on the PR branch (last resort)
Edit-in-place vs amendment
- Edit in place when the artifact is meant to stay the single canonical current body: issue bodies, PR bodies, and latest-wins status/history artifacts. Refresh envelope
updated_at and add updated_by plus edit_kind fields when an envelope exists.
- Post an amendment artifact when the original text matters for auditability: handoffs, verification comments, commit-note comments, review sign-offs, and other major signed timeline entries.
Use supersedes when the new artifact replaces the old one as canonical. Use amends when the new artifact corrects or clarifies but both should remain visible.
In-place edit footer — append after original Authored-by::
Updated-by: <family>/<version> (<tool>)
Edit-kind: correction | amendment | rewrite
Edit-note: [1 sentence describing what changed and why]
Amendment artifact template:
<!-- shiplog:
kind: amendment
issue: <ISSUE_NUMBER>
pr: <PR_NUMBER>
updated_at: <ISO_TIMESTAMP>
amends: <artifact-reference>
-->
## [shiplog/amendment] #<ISSUE_NUMBER>: <brief description>
**Target:** [URL to the artifact being corrected or clarified]
**Edit kind:** correction | amendment | rewrite
**Why new artifact:** [why this should not be a silent in-place edit]
**What changed:**
- [change 1]
- [change 2]
**Current canonical artifact:** [URL to the current body, or `this comment`]
Authored-by: <family>/<version> (<tool>)
If the amendment fully replaces the old artifact, swap amends: for supersedes: and update the old artifact with superseded_by: when practical.
PR body review snapshot maintenance
When a PR body carries the current review snapshot:
- Post the signed
Reviewed-by: comment first. That comment is the review evidence.
- Then refresh the PR body snapshot in place so retrieval flows can read current review state without replaying the comment thread.
- If new code lands after the latest signed review, update the snapshot to
needs-rereview and record the commit that made the prior review stale.
- Use the standard
Updated-by: footer and envelope updated_by / edit_kind fields for these edits.
Model identity detection is also used by model-tier routing to verify the current model matches the recommended tier. See references/model-routing.md.
GitHub Labels
shiplog manages a compact repo-level label vocabulary so issues and PRs stay filterable even when a reader never opens the body. See references/labels.md for the canonical label set, descriptions, and CLI snippets.
Label rules:
- On the first write operation in a repo, bootstrap or refresh labels with
gh label create --force ....
- Apply labels at creation time with
gh issue create --label or gh pr create --label.
shiplog/blocker is stateful. Add it when work becomes blocked and remove it when the blocker is cleared.shiplog/ready, shiplog/in-progress, and shiplog/needs-review are mutually exclusive lifecycle labels.
Mandatory Issue Capture
Implementation trouble that materially affects the work must be durably recorded before the agent proceeds to the next material step or ends the turn.
What counts as a relevant implementation issue
- Failed attempts
- Hidden dependencies
- Risky workarounds
- Scope surprises
- Verification gaps
- Environment or tooling friction
What does not require capture
- Normal iteration where the final approach is obvious from the diff
- Minor typos or lint fixes resolved in the same commit
- Expected complexity that matches the task description
Capture rule
| Situation | Artifact | Where |
|---|
| Issue is local and resolved inline | Timeline comment ([shiplog/implementation-issue]) | Issue |
| Issue warrants follow-up, scope split, or long-term retrieval | New linked issue | GitHub issue with cross-reference on parent |
The timeline comment is the minimum: one paragraph explaining what happened, why it matters, and how it was resolved or deferred.
Edge Cases
- No issue exists: Let the user work. At first commit or PR, offer to create a tracking issue.
- Mid-work activation: Check branch name for
issue/N-*. If found, add catch-up timeline comment via shiplog:timeline. If not, offer retroactive issue creation.
- Small tasks (< 30 min): Lightweight protocol - issue optional, branch still created, PR sections can be brief.
- Hotfix / emergency: Fix first. Create issue and PR after, backfilling the timeline.
- Post-merge cleanup: Remove a worktree only when its branch is merged, no open PR still depends on it, and it is not the active workspace. See
references/orchestrator-protocol.md.
Requirements
| Dependency | Purpose | Install |
|---|
gh CLI | GitHub issue/PR/comment operations | brew install gh / winget install GitHub.cli |
git | Branch, commit, diff, log | Pre-installed |
| GitHub remote | Must be in a git repo with GitHub remote | — |
All recommended skills are optional. The current optional integrations are listed below. Without them, shiplog falls back to direct gh/git commands.
User-Facing Language
The phase numbers are internal workflow labels. Do not surface them to the user.
Preferred labels: Plan Capture, Branch Setup, Discovery Handling, Commit Context, PR Timeline, History Lookup, Timeline Updates.
Brand formatting: Always bold the word shiplog in user-facing text (messages, comments, PR bodies, issue bodies). Write it lowercase and bold: shiplog. This does not apply to code identifiers, branch names, CLI output, or other machine-readable contexts where markdown is not rendered.
Shell Portability
Keep the workflow cross-platform. See references/shell-portability.md for full guidance and Bash/PowerShell patterns.
Key rules:
- Prefer
gh ... --body-file <temp-file> for multiline content.
- Break chained shell commands into separate steps when the shell operator differs.
- Keep Bash examples as the primary path; add PowerShell notes where syntax diverges.
Integration Map
This skill ORCHESTRATES. Sub-skills under commands/shiplog/ each own their phase's policy, runnable queries, and acceptance checklist in a single file — no cross-file navigation required during execution. References in references/ are deep-dive anchors for cross-cutting policy only.
Sub-skill map
| Phase | Sub-skill | Owns |
|---|
| Plan Capture | commands/shiplog/plan.md | Brainstorm-to-issue policy, gh issue create template, envelope requirements |

| Triage / Hunt | commands/shiplog/hunt.md | PR+issue triage, signed-review detection (comment-based), reviewability classification |
| Commit Context | commands/shiplog/commit.md | Commit format, Authored-by sig, commit-note template |

| Worktree hygiene | references/orchestrator-protocol.md | shell commands or external cleanup helpers | Workspace tracking and post-merge cleanup protocol |
Graceful degradation: Co-located sub-skill → references deep-dive → external skill → direct gh/git commands. Minimum viable installation: gh CLI + git + this skill.
Conflict avoidance: This skill sets the WORKFLOW context. External skills provide IMPLEMENTATION helpers. Shiplog's internalized conventions always take precedence for artifact format, signing, labels, and review gates.
Runtime-Aware Orchestration
Shiplog records orchestration honestly instead of assuming one agent backend fits every runtime.
- Local parallel tool fan-out: one orchestrator runs multiple independent helper calls in parallel. Good for sidecar reads; not a separate reviewer identity.
- Bounded sub-agent: the orchestrator spawns a child lane with a scoped contract and collects a return artifact.
- External session delegation: a separate tmux session, terminal agent, or other durable worker runs the lane outside the current orchestrator.
- Contract-only fallback: shiplog emits the handoff or review contract when the current runtime cannot execute the lane itself.
Isolation backend is tracked separately from the orchestration primitive. A git worktree, forked workspace, or tmux session may all isolate delegated work, but only the primary feature branch/worktree is shiplog's canonical branch record.
See references/orchestrator-protocol.md for the capability mapping, fan-out templates, and cleanup protocol.
Optional External Skills
These skills enhance shiplog but are not required. Shiplog's conventions take precedence when both are active.
