Exact values live in the header above. This text explains how and why to use them. It is written in plain language (ISO 24495-1:2023). + +## Overview + +**Creative North Star:** "Evidence Desk". A calm, near-black inspection surface where the code is the main thing and every change shows its reason. It serves the one thing users should remember: *"I can see exactly what the agent did."* + +**Product context:** codeboost is a single-user, local, open-source developer tool. It turns GitHub issues into plans, runs AI agents on each plan item, and lets you review the pull request one plan item at a time. Its peers are Linear, GitHub's review screen, and code editors. See `docs/designs/codeboost-plan-indexed-review.md`. + +**Mode per surface:** every screen is **Operate**. You come to finish a task, not to be persuaded. + +**Reference sites:** [Linear's UI redesign](https://linear.app/now/how-we-redesigned-the-linear-ui) for restraint in how much color is used. [Dark-mode accessibility guidance](https://atmos.style/blog/dark-mode-ui-best-practices) for status colors. + +**Key characteristics (first five seconds):** +- The code pane is the largest, brightest thing on the screen. +- Lines, not boxes. Panes are divided by 1px lines, never by cards or shadows. +- Blue means "you can click this". Nothing else is blue. +- Status is always an icon plus a word plus a color. +- Unplanned code carries a red hatched strip that is visible before you read a single line. + +## Colors + +**Strategy:** Restrained. Neutral grey-blue surfaces, one accent, and four status colors. Color is rare, so it always means something. + +**Light or dark:** Dark. You review code at your desk, often at night after an overnight run, for long stretches beside a dark code editor. A dark surface reduces glare and keeps diff colors readable. + +**How to use the colors:** +- **Surfaces step up in brightness:** canvas → surface → surface-raised → surface-selected. Hierarchy comes from these steps and from the `line` color, not from shadows. +- **`primary` (light blue) marks only things you can act on:** buttons, links, the current tab, and focus rings. Never use it for status or decoration. Text on a primary button uses `on-primary` (dark), which gives 9.8:1 contrast. +- **Status colors carry meaning:** + +| Token | Meaning | Icon and word | +|---|---|---| +| `success` | OK: passed, in scope, approved | ✓ plus a word such as "OK" or "Passed" | +| `warning` | Attribution warning, stale | ! plus a word such as "Stale" or "Ambiguous" | +| `error` | Scope or test failure, blocker, unplanned | ✕ plus a word such as "Fail" or "Unplanned" | +| `neutral-status` | Not applicable | – plus "N/A" | + +- `success` is much lighter than `error`. This lets red-green color-blind users still tell them apart by brightness. Never rely on hue alone. +- **Contrast (checked 2026-09-22):** every text and status color is at least 5.0:1 on every surface. Body text is 14.6:1 on `surface`. +- **Diff backgrounds:** `diff-added-bg` and `diff-removed-bg` are quiet tints. The `+` and `−` signs carry the meaning, not the tint. + +## Typography + +**Faces:** IBM Plex Sans for the interface, and IBM Plex Mono for code, file paths, commit IDs, plan-item IDs, and numbers. Plex was drawn for engineering documentation, which suits a tool about inspecting evidence. The two faces share proportions, so code and interface sit together calmly. + +**Why Plex is allowed here:** IBM Plex Sans is on the "too common for headlines" list. It is used here only as interface text on an Operate surface, which the rule permits. There are no marketing headlines in codeboost. + +**Loading:** self-host both families (weights 400, 500, and 600 for Sans; 400 and 500 for Mono) with `font-display: swap`, so codeboost works offline. Fallbacks: `"IBM Plex Sans", "Segoe UI", sans-serif` and `"IBM Plex Mono", Menlo, Consolas, monospace`. + +**Scale:** 12px labels and code, 13px interface text, 14px reading text (conversation and lesson details), 16px section headings, 20px page titles. Levels differ by size and weight, not by weight alone. Use tabular numbers (`tnum`) wherever numbers line up in columns. + +**Small text on purpose:** 13px interface text is below the common 16px body guideline. The user chose a compact, dense tool. High contrast (at least 5:1) and a 32px row height keep it readable. Longer reading text uses 14px. + +## Layout + +**Desktop only, from 1280px** (design review D25). + +| Width | Layout | +|---|---| +| 1440px and wider | Three panes. Plan list 232px, code fills the rest, conversation 344px | +| 1280–1439px | The conversation pane collapses to a tab. The plan list narrows to 208px | +| Below 1280px | A notice asks for a wider window | + +**Frame:** a 44px app bar (the shared menu, design review D13), then a 48px review strip (issue, PR, revision, progress, blockers), then full-height panes. Panes can be resized and collapsed. + +**Rhythm:** a 4px base grid. Rows are 32px. Pane padding is 12px. Space between sections is 16px or 24px. Keep density tight inside lists and give the code pane the most room. + +## Elevation & Depth + +There are no shadows and no glows. Depth comes from the surface brightness steps and 1px `line` borders. A popover or menu uses `surface-raised` with a 1px `line` border. If a real shadow is ever needed for a floating menu, it must be offset (for example 0 4px 12px at 40% of canvas), never a zero-offset colored halo. + +## Shapes + +- Panes, lists, and the code area have square corners (`rounded.none`). They are layout, not cards. +- Buttons, inputs, tags, and chips use `rounded.sm` (4px). +- Menus and popovers use `rounded.md` (6px). An element inside one uses 6px minus its inset. +- `rounded.full` is only for small status dots. + +## Components + +**Every interactive component has these states:** +- **Hover:** background one surface step brighter, or `primary-hover` for primary buttons. +- **Focus-visible:** a 2px `focus-ring` outline with a 2px gap. It must look different from the selected-row fill. +- **Active:** the same as hover, with the outline kept while focused. +- **Disabled:** text in `text-muted` and no hover change. A disabled button still explains itself; for example, the merge button reads "3 blockers". + +**Logo.** A terminal prompt (`>_`) inside a rounded square, followed by the word "codeboost". +- It sits at the left of the app bar on every screen, 20px square, with 8px between the mark and the word. +- The mark and the word use `text`. They are never blue, because blue means "you can click this". +- The mark is drawn with 1.4px to 1.5px strokes and round caps, so it matches Plex's weight at 13px. +- Screen readers skip the mark (`aria-hidden`) and read the word. + +```svg + +``` + +**List row:** 32px high. Shows ID, title, count, and status icons. The selected row uses `surface-selected`. + +**Status mark:** icon + word + color, with a screen-reader label such as "In scope: fail, 1 file outside declared files". + +**Provenance gutter (the signature component).** A 56px column to the left of the line numbers in every diff. +- Each changed block shows the ID of the plan item that made it, such as `P2`, in Plex Mono with `text-muted`. +- A block that belongs to no plan item gets a red diagonal-hatched strip in `unplanned-hatch` and the word "Unplanned" beside it. +- An ambiguous block shows "Ambiguous" with the ! icon in `warning`. +- The gutter is read aloud with its block, for example "Lines 118 to 129, plan item P2". + +**File-change card:** sits inside the code pane in change order. It has a `line` border, `rounded.sm`, an icon for the kind of change, old → new values in Plex Mono, and a "Details" expander. + +**Tables (Lessons, Learning):** 32px rows, sortable headers with a visible sort arrow, and a filter bar above the table. Rows expand in place, with no side panel. + +## Do's and Don'ts + +- **Do** use `primary` only for things you can act on. +- **Do** pair every status color with its icon and a word. +- **Do** give the code pane the most width and the brightest text. +- **Do** show the provenance gutter on every diff, including file-change cards. +- **Do** check any new color pair for at least 4.5:1 contrast before using it. +- **Don't** wrap panes, messages, or files in cards, and never put a card inside a card. +- **Don't** use shadows, glows, gradients, or colored halos. +- **Don't** use blue, purple, or accent colors to decorate. +- **Don't** add a colored left border to a card to show state. Use the status mark instead. The provenance gutter is a column in the diff, not a card border. +- **Don't** use a serif or italic display face. All text is Plex. + +## Motion + +- **Approach:** minimal and functional. Motion only explains a change of state. +- **Easing:** enter ease-out, exit ease-in, move ease-in-out. +- **Duration:** micro 80ms (hover and focus), short 150ms (expand a row, switch a tab), medium 250ms (open or collapse a pane). Nothing longer. +- **The one designed moment:** when you approve a plan item, its status mark fills from an outline to a solid ✓ in 150ms, and the progress count updates. +- **Reduced motion:** if the user asks for reduced motion, all transitions are instant. + +## Decisions Log + +| Date | Decision | Rationale | +|---|---|---| +| 2026-09-22 | Initial design system, "Evidence Desk", created | Created by /design-consultation from the design review (D22), the approved mockups, 2026 dev-tool research, and two outside proposals (Codex "Evidence Desk", Claude subagent "Flight Recorder") | +| 2026-09-22 | IBM Plex Sans and IBM Plex Mono, verified on Google Fonts; self-hosted | One engineering-document family.

Architecture** +1. `[P1] (8/10)` Keeping unattended runs safe, "Invocations run with `HOME` set to a per-task scratch directory" — Codex reads sign-in from `CODEX_HOME` (default `~/.codex`) and Claude reads `~/.claude.json`. A scratch `HOME` signs both tools out, so every unattended run fails. → R1 +2. `[P1] (7/10)` Keeping unattended runs safe, "the network is off" — The OS sandbox covers shell commands. Claude's WebFetch and WebSearch tools and any MCP servers run outside it, so issue text could still make the agent send data out. → R2 +3. `[P1] (8/10)` How we will know it works, "adds one out-of-scope change at a random place" — The plant script's commit has no trailer, so it always lands in the red Unplanned row. The test never checks the hard cases: an agent's unrelated edit inside a plan item's commit, in a declared or undeclared file. Neither signal can catch an unrelated edit inside a declared file. The Summary does not say so. → R3 +4. `[P3] (8/10)` Probe — The org ruleset runs Copilot code review on every push. Each rebase push starts a new Copilot review on the PR. It does not block merging. No decision needed. It is noted under Failure modes. + +**Section 2. Code quality** +5. `[P2] (7/10)` Assigning ambiguous or unplanned changes, "codeboost remembers your choice by file and exact content" — Two identical segments in one file (such as two `}` lines) share one key, so one decision silently applies to both. → R4 +6. `[P2] (7/10)` How rebasing works, "Every commit belongs to exactly one plan item" — A commit pushed by someone else has no trailer. The conflict protocol does not say what to do when git stops on it. → R5 +7. `[P2] (7/10)` Approving and merging, step 4 "codeboost waits for GitHub's required checks" — In a repo with no CI, `gh pr checks` reports no checks, and the design does not say whether that passes or waits 30 minutes. → R6 +8. `[P2] (7/10)` Tools and storage, "`sql.js` instead" — Probe: `node:sqlite` loads with no warning on Node 26. `sql.js` keeps the database in memory and rewrites the whole file on save, which weakens the crash recovery the design depends on. → R7 +9. `[P3] (9/10)` Scope record — D1 did not place storage access or the command-line entry. → R8 + +**Section 3. Tests** + +No test framework exists yet (the repo holds only `LICENSE`, `CLAUDE.md`, and this document). Every path below is planned, not built, so every path is a gap today.

If the same file has two identical changes, such as two lone closing braces, one choice silently applies to both. You could accept one and unknowingly accept the other. +Stakes if we pick wrong: a change you never looked at gets accepted and can be merged. +Recommendation: A, because counting which copy it is (first, second) is simple, and when the count shifts codeboost just asks you again, which is the safe failure. +Completeness: A=9/10, B=8/10, C=4/10 +Net: simple and safe (A), survives reordering but lapses more often (B), or a silent bug (C). +Header: Segment key +Options: +A) Add occurrence number (recommended) +Key each choice by file, content, and which copy it is among identical segments in that file (1st, 2nd, …).

If that causes a conflict, it asks the agent for the plan item that made the conflicting commit to fix it. But if a person pushed a commit to the PR branch, that commit belongs to no plan item, and the design does not say who fixes it. +Stakes if we pick wrong: an agent could rewrite code a person wrote, with no plan item watching it, or the task could hang. +Recommendation: A, because codeboost should never let an agent rewrite code that no plan covers. Stopping and asking you is rare and safe. +Completeness: A=9/10, B=6/10, C=3/10 +Net: stop and ask you (A), let the agent fix it and flag the result (B), or undefined (C). +Header: Foreign conflict +Options: +A) Stop and ask you (recommended) +Cancel the rebase so the branch is unchanged, move the task to needs human, and show the commit and its author. ✅ No agent ever edits code that no plan item covers. ✅ Simple, and the branch is always left as it was. ❌ You resolve that conflict yourself.

The design adds a backup engine, sql.js, in case the built-in one is missing. On Node 26 the built-in engine works with no warning. The backup keeps the whole database in memory and saves it all at once, so a crash can lose recent task state, which the recovery design depends on. +Stakes if we pick wrong: keep the fallback and crash recovery can silently lose work on some computers.

Each snapshot has a unique version-qualified `$id` matching its registry path under `https://github.com/codeabovelab/codeboost/schema/` (for example `versions/1/plan.schema.json`). Future versions must use new IDs so all retained schemas can coexist in one validator. After release, snapshots are immutable, including descriptions. The unversioned `schema/plan.schema.json` and `schema/plan-edit.schema.json` are exact copies of the current snapshots for CLI compatibility; verification must check those copies against the registry. - Parse the input as data, require an integer `schema_version`, and look it up in the registry without constructing a path from user input. Reject missing or unsupported versions. A new version adds a new directory and registry entry; retain all earlier entries. With only version 1 registered there is no migration to run. - Keep released schemas unchanged. On import, read `schema_version`, validate against that version's schema, convert using an explicit version migration, then validate against the current schema and run the meaning checks. Reject unsupported versions with an explanation. Never validate an old plan against a newer schema before converting it. Suggested edits must use a supported schema version and still match the current plan revision; otherwise ask the assistant to regenerate them. diff --git a/schema/plan-edit.schema.json b/schema/plan-edit.schema.json index f49429d..6690dbb 100644 --- a/schema/plan-edit.schema.json +++ b/schema/plan-edit.schema.json @@ -1,5 +1,5 @@ { - "$id": "https://github.com/codeabovelab/codeboost/schema/plan-edit.schema.json", + "$id": "https://github.com/codeabovelab/codeboost/schema/versions/1/plan-edit.schema.json", "title": "codeboost plan edit", "description": "The plan assistant's answer on the Plans screen: a reply to the person, plus zero or more suggested edits to one plan revision.

Retained schemas have explicit registry paths, and repository metadata in authoring prompts uses escaped JSON data blocks just like issue text.

Outside quotes reject shell metacharacters `;`, `&`, `|`, `<`, `>`, `$`, backticks, parentheses, glob characters (`*`, `?`, `[` and `]`), braces, `!`, `#`, and `~`; inside quotes they are ordinary literal characters. Reject an empty command or executable. Do not expand variables, globs, substitutions, or home paths. Match the resulting complete argv against the approved array exactly.

Serialize all free-form fields, including `intent`, file `change`, and acceptance text; escape `<`, `>`, and `&` as JSON Unicode escapes, and never recursively expand placeholders in values. The trusted prompt defines the phase and asks the agent to act on the approved task data; text inside a field cannot change tool permissions, authorize another command, change roles, or escape that phase. Tool dispatch uses separately validated structured scope/argv, never instructions extracted from prose. Hostile-field evaluations must include forged closing delimiters and demands to run an unapproved command. Serialization prevents delimiter breakout, not semantic injection; enforced permissions remain necessary. + +## Checks after import + +The schema checks the shape. codeboost then checks the meaning.

Require a selected task before import; a mismatch fails without changing the task or rewriting the plan. | Failure | +| Item IDs are unique. | Failure | +| Every `depends_on` ID exists, comes earlier in the list, and there is no loop. | Failure | +| Both `path` and `renamed_from` use canonical repo-relative forward-slash form: reject absolute/drive paths, backslashes, control characters, empty components, `.` and `..`, repeated or trailing separators, and `.git` components. Do not silently rewrite paths. Before duplicate, occupancy, dependency, or projected-state checks, compare filesystem identity keys using the actual task checkout's case and Unicode equivalence rules; reject aliases that name the same entry (for example `src/A` and `src/a` on a case-insensitive checkout). If those rules cannot be established, fail closed. Apply the same keys to base-tree paths and projected paths. | Failure | +| No parent component of `path` or `renamed_from` is a symlink in the projected state, and neither path points into `.git`. Inspect components without following links. In version 1, the final component may be a pre-existing symlink identified by the base Git tree's symlink mode, with that type carried through projected renames. A path declaration alone never authorizes converting a regular file into a symlink. Edits, deletes, and renames of such a link operate on the link itself, never its target. Version 1 rejects new symlinks and regular-file-to-symlink conversions; supporting them requires a future schema version with typed declarations, not interpretation of `change` prose. Inspect the stored target text without following it; any new or retained target must resolve within the repo, outside `.git`, without traversing another symlink. Deleting or replacing an unsafe existing link is allowed if the resulting state satisfies these rules. Recheck the actual target after the run, before committing. | Failure | +| Each declaration names one leaf Git entry (regular file or permitted pre-existing symlink), never the repository root, a directory/tree, or a gitlink (v1 only reviews foreign gitlink changes). A declaration never authorizes descendants; moving or deleting a directory requires enumerating its affected leaf entries. Reject destinations occupied by a directory and any child path beneath a projected file, symlink, or submodule. | Failure | +| For a declared pre-existing symlink, resolve its target identity without following filesystem links and reject the item if that target is also a writable declared entry, or is a directory containing any writable declared descendant, in the same invocation. Use filesystem identity keys and path-component ancestry (not string-prefix comparison); for example `link -> target/` conflicts with `target/file`. A link and its target cannot both be edited under one item; split legitimate changes into separate dependent items. Managed link operations use unlink/recreate or rename without dereferencing the link. Post-run path diffs alone cannot prove which spelling an arbitrary program used to write. | Failure | +| File operations are valid in the projected repo state immediately before the item runs (see below). `edit` and `delete` need an existing path; `add` needs an unused path; `rename` needs an existing `renamed_from` and an unused destination `path`. | Failure | +| `renamed_from` is set only for kind `rename`. | Failure | +| The same path is not declared twice in one item. | Failure | +| The item has at least one `cmd`. | Warning: "No test command" | +| Each `cmd` is parsed as one executable and literal arguments, with the entire argv matched element-for-element against a repo-approved argv entry. Prefix matches, appended flags, extra arguments, and argument substitution are not allowed.

Execute the resulting argv without a shell. | Invalid syntax blocks approval; a valid but unlisted command warns and cannot run until allowed | +| A completed agent invocation changes a dependency or a script codeboost will run. | Before its own installation or script invocation, codeboost stops in "needs approval". This post-invocation gate cannot prevent an agent from executing a changed script during its invocation; container and network restrictions must already contain that execution. | +| `questions` is not empty. | The plan shows the questions at the top; answer them or approve anyway | + +**Submodules in version 1.** Gitlinks are review-only metadata leaves: the linking engine can display and attribute externally produced pointer changes, but v1 plans cannot author, add, delete, or rename a gitlink. Reject declarations targeting an existing gitlink and reject agent-produced gitlinks. Authoring them requires a future typed target-commit field and runner-controlled operation. Do not initialize or update nested submodule worktrees. Before each agent or check invocation, reject an initialized/populated gitlink directory and bind an empty read-only mount at every existing gitlink path; refuse the invocation if that protection cannot be enforced. Before tests and before committing, inspect gitlink locations without following links and reject nested content, including content under newly introduced gitlinks. A top-level Git diff is not enough. Reviewing submodule pointers reads the Git entry only; the agent never receives an editable nested checkout. Tests must attempt writes beneath a gitlink and provide a pre-populated nested checkout, and both must be refused. + +**Clean invocation state.** Before every invocation, including restart/retry, materialize a fresh task filesystem from the recorded trusted head. Do not reuse a partially written checkout or rely on `git reset` to remove untracked files. Keep ledger/plan state outside that filesystem and preserve previous output separately for diagnosis. Inspect actual entries without following links immediately before launch: reject unexpected/untracked entries, occupied add destinations, or symlink parents that disagree with the projected state. No agent/check runs until actual occupancy and entry types agree. Test restart with an untracked symlink parent and an occupied add destination. + +**Git metadata trust.** Mount the task's `.git` read-only for the agent, including execution/fix phases; only the runner may create commits or update refs after the invocation ends. Before any post-run Git command, inspect metadata with ordinary filesystem reads against the runner-owned baseline and reject unexpected changes. Runner Git uses a sanitized immutable configuration and an explicit environment: no inherited Git variables, user/system config, hooks, fsmonitor, external diff/textconv, clean/smudge filters, SSH commands, or credential helpers supplied by the task. Network/push endpoints and credentials come only from trusted runner settings. Build that config outside the writable task mount and do not read agent-provided config before this audit. Tests must plant each command-helper setting and prove that status/diff/add/push inspection never executes its marker. + +**After each run, codeboost checks the result too.** A plan check alone cannot stop an agent from creating a new symlink and writing through it. So after each invocation, before committing, codeboost: records otherwise-safe regular-file changes outside the declared list as out of scope, commits them with the owning item, and exposes them for review; these are scope findings rather than safety violations. They deliberately pause the task in "needs amendment" before any later item or check invocation. After a person approves a revised plan and continuation, reconcile the executed prefix with the audited current head and validate remaining operations from that actual checkpoint; never silently authorize the extra file or erase its original scope finding. Separately, the safety audit rejects new symlinks or regular-file-to-symlink conversions (a renamed pre-existing symlink is tracked by its base-tree lineage); permits changed pre-existing links only at declared paths and rejects targets that leave the repo, enter `.git`, or traverse another symlink; and rejects any agent change to `.git` itself (including config, hooks, refs, and objects). Any safety violation stops tests and commits and moves the task to needs human; preserve the rejected output separately for diagnosis. Only after this audit may the runner create its own objects and commit. Hooks are disabled (`core.hooksPath=/dev/null`) in addition to the metadata/config isolation above; disabling hooks alone is not sufficient. + +**Projected file state.** Start with the paths at the plan's base commit, then walk items in their listed execution order. Check an item's file operations against the state before that item; after it passes, apply its declared additions, deletions, and renames to the projected state before checking the next item. No repo files change during validation. This describes initial plan validation. On an approved continuation after an out-of-scope pause, retain the execution history and use the audited checkpoint for the remaining suffix rather than pretending the old declared-only projection describes the actual tree. A path may participate in only one operation per item, counting both the source and destination of a rename. If an item uses a path created or renamed by an earlier item, it must depend on that item, directly or through other dependencies. + +For example, P1 may add `src/new.go`, then P2 with `depends_on: [P1]` may edit it. Likewise, P1 may rename `src/old.go` to `src/new.go`, then P2 may edit the new path. Editing a missing path, adding an existing path, or renaming onto an occupied path blocks approval. Recompute the projected state from the base commit after each plan edit. + +Issue text and agent-produced plan fields remain untrusted. The prompt builder serializes issue data and previous plans as JSON and escapes delimiter characters before insertion (see the template). Escaping prevents data from closing its wrapper; it does not guarantee that a model ignores malicious instructions. Human plan approval, command validation, and the container remain required. Test both delimiter-escape payloads and instruction-like issue text. + +## How a plan gets into codeboost + +| Source | What happens | +|---|---| +| **Claude or Codex drafts it** | codeboost runs the agent with the prompt in [`prompts/plan-author.md`](../prompts/plan-author.md) and passes the schema.

Approving saves the revision. | + +codeboost keeps the master copy in its own database.

Before an assistant request starts, the server persists an opaque request ID bound to the stable repository/task/plan IDs, schema version, and base revision. Store its response/suggestion IDs under that captured context only; never attach a late result to the currently selected UI plan. Apply accepts a server-issued suggestion ID, loads its bound context, and atomically verifies the target plan identity and revision before mutation. Reject unknown, canceled, cross-plan, or stale requests. A matching revision and item IDs on another plan are insufficient. The assistant response need not echo trusted IDs, and any identity claims in free text are ignored. Test two plans at revision 3 with P1 while a delayed response for A arrives with B selected: B must remain unchanged. + +To change a declared path or rename destination, import a complete replacement plan as a new revision and run all meaning checks. Separate add/remove suggestions are permitted only when each intermediate plan is valid; they are not an atomic path-change operation. Do not infer the old entry from prose or list position. + +Fields an operation does not use are `null`. The strict answer schema checks structure, not the relationship between `op` and its payload. Before showing an enabled Apply button, a semantic validator must enforce the operation table: required payloads are non-null, unused payloads are null, and `item` identifies an existing item except for `add_item`, where it matches the unique `new_item.id`. File updates/removals must target an existing entry; additions must not duplicate one; `check_index` must be in range; and `set_field` must satisfy the destination field's limits. Reject invalid suggestions with an explanation. Dry-run each edit on a copy and run both the plan schema and all meaning checks; repeat against the current revision atomically when Apply is clicked.

This applies to both plan and suggested-edit schemas. +- A nullable field is still required. Adding one breaks old plans (the field is missing) and old readers (the field is unknown), so it must not be added under version 1. +- [`schema/versions.json`](../../../schema/versions.json) is the version registry. Its `current` number selects the schema used for new drafts; its `versions` object maps exact decimal version numbers to plan/edit schema paths, a normative semantic-contract path, and a semantic-validator dispatch key. Paths are relative to `schema/`. Version 1 is retained at `schema/versions/1/plan.schema.json` and `schema/versions/1/plan-edit.schema.json`. Each snapshot has a unique version-qualified `$id` matching its registry path under `https://github.com/codeabovelab/codeboost/schema/` (for example `versions/1/plan.schema.json`). Future versions must use new IDs so all retained schemas can coexist in one validator. After release, snapshots are immutable, including descriptions. The unversioned `schema/plan.schema.json` and `schema/plan-edit.schema.json` are exact copies of the current snapshots for CLI compatibility; verification must check those copies against the registry. +- Each released version also freezes its parser subset, command tokenizer, projected-state/path/symlink checks, and suggestion/identity semantics in the registered `semantics` document. The registry's `validator` key dispatches to a dedicated version-specific implementation and retained conformance fixtures; never apply the latest validator to an older version. For v1 the key is `v1` and the normative document is `versions/1/semantics.md`. Schema and semantic acceptance changes require a new version together. Bug fixes may restore conformance to a frozen contract, but may not silently redefine it. Treat a missing validator implementation as unsupported. The current guide may explain the contract, but cannot override a released snapshot. +- Parse the input as data, require an integer `schema_version`, and look it up in the registry without constructing a path from user input. Reject missing or unsupported versions. A new version adds a new directory and registry entry; retain all earlier entries. With only version 1 registered there is no migration to run. +- Keep released schemas unchanged. On import, read `schema_version`, validate against that version's schema, convert using an explicit version migration, then validate against the current schema and run the meaning checks. Reject unsupported versions with an explanation. Never validate an old plan against a newer schema before converting it. Suggested edits must use a supported schema version and still match the current plan revision; otherwise ask the assistant to regenerate them. + +**PR #1 review decisions.** File validation uses projected state so dependent items can work on new or renamed files. Version changes are explicit because every field is required and unknown fields are rejected. T18 includes regression checks for both rules. + +## PR #1 feedback dispositions + +The script approval gate covers codeboost-run commands, while container and network isolation must contain an agent that edits and immediately executes a script. Symlink parent components are prohibited; version 1 supports declared pre-existing final links, identified by Git mode and tracked through renames, with target checks. New links and ordinary-file conversions require a future typed schema. Canonical path checks use the task filesystem's identity rules. A declared link and its writable target cannot share an invocation. Gitlinks remain metadata-only, with empty read-only nested paths and pre-test/post-run audits. Imported plans must match the already-selected issue and repository context. Retained schemas have explicit registry paths, and repository metadata in authoring prompts uses escaped JSON data blocks just like issue text. These are semantic/runtime requirements, not guarantees supplied by JSON Schema alone. + +## Notes for builders + +- **The schema files have no `$schema` line.** Claude Code's `--json-schema` rejects the draft 2020-12 URL (tested with Claude Code 2.1.278). Validate with a draft 2020-12 validator, set in code. +- **Strict-mode rule.** Every object lists all its properties in `required` and sets `additionalProperties: false`. Optional values are nullable. Keep this rule for every new field, or Codex's `--output-schema` may refuse the schema. +- **One file per schema.** Each agent receives one schema file, so `plan-edit.schema.json` holds exact copies of the `item`, `file`, and `check` definitions. A test must fail if the copies differ. +- **Closing stdin.** `codex exec` reads extra input from stdin when stdin is not a terminal, and waits forever if nothing arrives. Always run it with stdin closed (`< /dev/null`). +- **Tested with:** Claude Code 2.1.278 and Codex CLI 0.153.4, 2026-09-22. Both returned plans and suggested edits that passed both schemas. + +## Test this document with a reader + +Before relying on this format, ask someone who has not seen codeboost to write a two-item plan for a small issue using only this page.
