Chat Release Notes

DIAL Chat release-notes enhancer

The CI publishes a release for every tag with bullets that are just the PR titles. Those bullets carry a lot of dirt — conventional-commit prefixes (feat(chat):, fix(chat):, feat(chat-e2e):, fix(overlay):), branch-style phrasing inherited from the PR title, duplicate entries when the same issue was patched twice (e.g. two (Issue #4696) (#6135) / (#6430) bullets in 0.45.0), Revert "..." lines that were never reconciled with their original entry, and a ## Other section that mixes maintainer-relevant bumps with pure tooling churn. The releases visible at https://github.com/epam/ai-dial-chat/releases from 0.43.x through 0.45.1 are what those raw notes look like after a human editorial pass. This skill reproduces that pass.

You are running in a forked, isolated context. Read and research freely — only the final summary you return reaches the main conversation. All file writes happen in this fork; the draft lands at claude/release-notes/<tag>-draft.md.

When to use

• "Enhance the release notes for 0.45.0-rc.55"
• "Look at the latest pre-release notes and refine them"
• "Help me adjust release notes for the current rc"
• "The CI just published <tag>, make it readable"

Do not trigger on requests like "what changed in 0.45.0?" — that is a recall question, not a notes-editing task.

Inputs

tag = $tag — the GitHub release tag to enhance (e.g. 0.45.0-rc.55, 0.46.0). If empty, pick the most recent tag from gh release list --limit 5 and confirm with the user before editing.

Workflow

1. Resolve target and reference styles

1. gh release view <tag> --json body,name,tagName — capture the raw CI notes.
2. gh release list --limit 10 — locate the previous tag of the same kind (last stable for a stable release, the predecessor rc for a delta rc.N+1).
3. gh release view <prev-stable-tag> --json body and gh release view <prev-rc-tag> --json body (when relevant) — these are the style anchors. The user has repeatedly insisted "keep the same format as the latest stable release" and "your notes are too verbose" — match the terseness of those notes, not your own instincts. One line per bullet.
4. git tag --list | sort -V + git log <prev-tag>..<tag> --oneline — full commit list for the range, so you can spot hotfix commits the CI dropped because they had no PR.

2. Pull source context for each bullet

For every bullet in the raw notes:

1. Parse out the trailing #<issue> (#<PR>) or (#<PR>). If only a PR number is present, that's the canonical reference; if both, keep #<issue> (#<PR>) order.
2. gh pr view <PR> --json title,body,labels — read the PR body, not just the title. The body is where the why and the what-it-replaces live; the title is usually too compressed.
3. For bullets without a PR number, find the commit with git log <prev-tag>..<tag> --oneline | grep -i <keywords> and git show <hash> — usually a hotfix commit that should fold into a related entry.
4. If a PR body references a doc under docs/, apps/chat-api/README.md, or libs/chat-overlay/README.md, skim it for the headline framing. Use the dial-docs skill to resolve which doc under docs/ is authoritative rather than guessing a filename.

3. Cross-check config-registry.constants.ts / source for deployment changes

The frontend (apps/chat) does not read env vars directly — all runtime config and feature flags are resolved server-side by apps/chat-api and served to the client through AppConfigContext. The Deployment Changes section is built from primary sources, not PR titles:

• git diff <prev-tag>..<tag> -- apps/chat-api/src/app-config/config-registry/config-registry.constants.ts — this CONFIG_DEFINITIONS array is the canonical registry for both operator-facing config values and feature flags. Each entry has key, type ('config' or 'feature'), valueType, visibility, defaultValue, description, owner, and optionally envVar / allowedRolesEnvVar. Additions/removals/changed defaultValue here are deployment-relevant.
• git diff <prev-tag>..<tag> -- apps/chat-api/src/config/environment.config.ts — the EnvironmentVariables class validated at boot; this is the source of truth for raw env var names, whether they're required, and their type/validation. Code wins over docs when a name conflicts.
• git diff <prev-tag>..<tag> -- apps/chat-api/README.md — curated, human-readable env var tables (grouped by concern: auth, DIAL Core, themes, file transfer/archives, deployments/catalog, voice/ASR, utility model). Use these for the description/default columns, but verify the canonical name against environment.config.ts or the envVar field in config-registry.constants.ts — past releases have caught doc typos this way.
• Confirm defaults by reading the defaultValue field in config-registry.constants.ts, or the access-site fallback in environment.config.ts when the var isn't in the registry.
• Entries in CONFIG_DEFINITIONS with type: 'feature' are the feature flags (see apps/chat-api/src/app-config/feature-flags/feature-key.enum.ts for the FeatureKey enum backing them). A removed entry means the flag no longer has any effect. The registry's description field is the source of truth for what the flag does — same "code wins" rule as env vars. Flags are resolved dynamically (env var + optional allowedRolesEnvVar role restriction) via FeatureFlagsService, not through a single ENABLED_FEATURES blob — do not describe them as such.

4. Classify each bullet (move things between sections, drop the noise)

The raw notes' ## Features / ## Fixes / ## Other partition is unreliable because CI keys it off the conventional-commit prefix in the PR title. Reclassify by the change's actual user impact:

Drop these from the notes entirely — they have no consumer-visible effect:

• All feat(chat-e2e): / fix(chat-e2e): / chore(chat-e2e): items unless the PR also touches apps/chat/src in a behavior-changing way (verify via gh pr view --json files).
• Pure refactors / formatting / lint / tsconfig / nx.json / project.json / Nx project-graph shuffles (chore(chat): refactor utils, chore: bump nx).
• CI / workflow changes (.github/workflows/**) unless a maintainer needs to know — then keep under Other with a one-line rationale.
• Pure dependency bumps with no CVE / no behavior delta (chore: bump types/node).
• Merge remote-tracking branch … commits.
• Claude Code agent setup / docs / skill scaffolding.

Keep in Other — items maintainers, embedders, or themers care about even if they're not features:

• Security-adjacent dependency bumps (bump axios, bump next).
• dial-ui-kit (visible default styles).
• Forwarded-headers / auth-handling checks.
• Issue templates, contributor docs (visible to contributors).

If you find yourself unsure whether to drop a bullet, ask: would a customer reading these notes care that this happened? If no, drop it.

5. Rewrite each kept bullet

The raw form is * <conventional-prefix(scope)>: <PR title> (Issue #<N>) (#<PR>). Rewrite to:

* <Active-voice description of what changed> — <brief why-it-matters or what-it-replaces> (Issue #<N>) (#<PR>)

Rules in order of importance:

1. One line per bullet. No multi-paragraph descriptions. The user has explicitly flagged "too verbose" in prior runs. If you need more detail, save it to the companion editorial-notes file (see §8), not the main draft.
2. Drop the conventional prefix (feat(chat):, fix(chat):, feat(overlay):, fix(i18n):). Replace with prose.
3. Drop branch-style phrasing. add prop to hide item name in path → Hide the item name segment in breadcrumb paths via a new prop. The PR title is the prompt, not the output.
4. Use a — em-dash for the "why" clause, not a hyphen or colon — that's the consistent house style across 0.43.x–0.45.x.
5. Backticks for code identifiers: env vars (THEMES_CONFIG_HOST, LIVE_CHAT_INTERACTION_ENABLED), feature-flag keys (features.asrEnabled), file paths, prop names, type names, overlay-API method names.
6. Preserve issue + PR refs at the end in (Issue #<N>) (#<PR>) parenthesised form, or (#<PR>) when there is no issue. Don't strip them — these notes ship as the GitHub release body where the numbers auto-link.
7. Prefix with [Preview] for preview-gated features.
8. Flag regressions explicitly: (regression fix) for items restoring previously-working behavior.
9. Quote CVE IDs verbatim for security upgrades: Upgrade axios to 1.7.9 to address CVE-2024-39338.

Example transformations

Each pair is raw CI → enhanced. Backticks in the enhanced form denote code identifiers in the actual output.

# Dropping `feat(chat):`, naming the concrete prop and surface:
- * feat(chat): add prop to hide item name in path (Issue #6210) (#6292)
+ * Hide the item name segment in breadcrumb paths via a new `hideItemNameInPath` prop on path-rendering components (Issue #6210) (#6292)

# Removing `fix(chat):` and naming the precise gap, marking regression:
- * fix(chat): fix quick app review flow when orchestrator does not support temperature (Issue #6637) (#6688)
+ * Fix Quick App review flow when the orchestrator deployment does not advertise `temperature` support (regression fix) (Issue #6637) (#6688)

# Folding two PRs that patched the same issue into one bullet:
- * fix(chat): publication request scrolling (Issue #4696) (#6135)
- * fix(chat): publication request scrolling follow-up (Issue #4696) (#6430)
+ * Fix scrolling inside the publication-request panel when the list overflows the viewport (Issue #4696) (#6135, #6430)

# Reverts whose original is in the same range — drop both:
- * feat(chat): introduce experimental thread-grouping (#6401)
- * Revert "feat(chat): introduce experimental thread-grouping" (#6488)
+ (drop both — net zero in the range)

# Revert whose original shipped earlier — keep, rephrase as roll-back:
- * Revert "feat(chat): aggressive prefetch of conversation history" (#6404)
+ * Roll back the aggressive prefetch of conversation history shipped in `0.44.0` — restores prior load-on-demand behavior (#6404)

# Dropping `feat(chat-e2e):` entirely (test-only):
- * feat(chat-e2e): updated tests with expand/collapse attachment feature (#6541)
+ (drop)

# Reclassified (raw had it in Other because of `feat(overlay):` prefix), prefixed [Overlay]:
- * feat(overlay): expose subscribeToEvents for prompt-selection (#6364)
+ * [Overlay] Expose `subscribeToEvents('promptSelected', …)` on `ChatOverlay` for embedders to react to in-chat prompt selection (#6364)

# Security bump → Fixes, phrased as user impact:
- * chore: bump axios to 1.7.9 (#6512)
+ * Upgrade `axios` to `1.7.9` to address CVE-2024-39338 (server-side request forgery in absolute-URL handling) (#6512)

# Theme-contract change → Other with [Theme] prefix:
- * chore(chat): bump dial-ui-kit to 0.20.0 (#6337)
+ * [Theme] Bump `@epam/ai-dial-shared` UI-kit to `0.20.0` — default button radii and disabled-state opacities shift; downstream themes overriding `--button-*` tokens may need a visual review (#6337)

# Folded orphan hotfix commits into a related fix entry:
- * publication URL escaping        (orphan commit, no PR)
- * fix tests                        (orphan commit, no PR)
+ * Escape `%` and `#` in publication URLs before they reach the router — fixes 404s on conversations with reserved characters in the title (`a1b2c3d`, `e4f5a6b`)

6. Build the Deployment Changes section

Add this section only when the range introduces at least one env-var, behavioral, or schema change. Pick subsections — include only the ones with entries:

## Deployment Changes

### New environment variables

<table: Variable | Default | Description>

### Deprecated environment variables

> [!CAUTION]
> Still works, but will be removed in future versions.
> <table: Variable | Replacement | Description>

### Removed environment variables

<table: Variable | Reason>

### New feature flags

<table: Flag | Description>

### Removed feature flags

<table: Flag | Reason / replacement>

### Behavioral changes

> [!NOTE]
> <one-line explaining the behavioral shift, e.g. preview→GA graduations>

- **<Feature>** — <field / module> (#<PR>)

Which subsection: telling Behavioral and Schema deprecations apart

These two look adjacent but answer different operator questions:

• Behavioral changes — "How does the deployed Chat app behave differently at runtime once I redeploy this image?" Default flag flips (e.g. a CONFIG_DEFINITIONS feature entry's defaultValue flipping to true), prefetch policy changes, default theme shifts, default model selection, error-handling shifts. Operator does nothing; the change is automatic on upgrade. Uses > [!NOTE].
• Schema deprecations — "What keys in my settings JSON or overlay options payload are being renamed?" Inside-repo schema evolution where the parser still accepts legacy keys via aliases. Uses > [!CAUTION] and a table.

If a change requires the operator to touch a config file outside this repo (DIAL Core's aidial.config.json, helm values.yaml, an external IDP config, an ai-dial-chat-themes deployment), it belongs in DIAL Configuration changes with a concrete remove/add migration list, never in Behavioral changes.

Crucial — what does not belong here: per-conversation settings, per-app overlay options the embedder passes at runtime, in-chat user preferences. Those changes belong in the Features bullet body where they're introduced. Deployment Changes is for operator-facing concerns: env vars, default-on/off behavioral shifts, schema-level deprecations.

For the env-var tables, the description column comes from apps/chat-api/README.md when the row exists there; otherwise from the description field of the matching CONFIG_DEFINITIONS entry, or the surrounding code in environment.config.ts. Cite default values verbatim from the doc table's "Default" column or the defaultValue field in config-registry.constants.ts.

For the feature-flag tables, the entries are the CONFIG_DEFINITIONS entries with type: 'feature' added or removed in the range (from the §3 config-registry.constants.ts diff), backed by the FeatureKey enum in apps/chat-api/src/app-config/feature-flags/feature-key.enum.ts. The Flag column uses the registry entry's key in backticks (e.g. `features.asrEnabled`, `features.liveChatInteraction`), not a separate kebab-case name — consistent with the §5 rule #5 that backticks feature-flag keys. The description comes from the entry's description field; if the entry has an envVar (e.g. LIVE_CHAT_INTERACTION_ENABLED) or allowedRolesEnvVar, mention it since operators toggle the flag through that variable, not through a single combined flags env var.

7. Pre-release / delta handling

If the target is <X.Y.Z>-rc.N with N ≥ 1:

• The release covers only what changed since the previous rc — do not consolidate or rewrite the predecessor's notes. Each pre-release tag has its own GitHub release page; the consolidation happens at the stable cut. (Note: ai-dial-chat rc trains can be very long — 0.45.0 shipped at rc.55 — so resist the urge to "summarise the whole train" on rc.N.)
• Drop sections that have no entries in the delta (e.g. no Deployment Changes if no env vars or behavioral shifts landed in this rc).
• Do not prepend a "Delta since " pointer at the top. The CI doesn't emit one, the previously-shipped rc notes don't carry one, and the -rc.N version suffix already signals what the release is. Adding a header just creates editorial noise the user has to clean up.

8. Save the draft (and optional editorial companion)

Create claude/release-notes/ if missing, then write:

• claude/release-notes/<tag>-draft.md — the final notes, ready to paste into the GitHub release body. No preamble, no commentary — just the headings and bullets.
• claude/release-notes/<tag>-editorial-notes.md (optional) — only when there are non-obvious calls worth surfacing to the user:
  • Rename mapping (raw bullet → enhanced bullet) for items where the rewrite is non-trivial.
  • List of items dropped, with one-line reason per item.
  • Open questions for the user (e.g. "Should #6488 overlay-API addition stay under Other ? It's only useful to embedders.").
  • Any place the source-of-truth diverged from the PR body (e.g. canonical env-var name).

9. Verify nothing was pushed to GitHub

This skill never runs gh release edit, gh release create, or any write operation against the repo. The user explicitly directed: "Everything should be drafted in local files. Don't push anything or change anything in GitHub." Draft files are the only output. If the user later asks you to apply, that is a separate, explicit request.

Output format

The file saved to claude/release-notes/<tag>-draft.md follows this shape exactly:

## Features

- <one bullet per change>

## Fixes

- <one bullet per change>

## Other

- <only consumer-, embedder-, theme-, or maintainer-relevant items>

## Deployment Changes

### New environment variables

<table>

### Deprecated environment variables

> [!CAUTION]
> …

<table>

### New feature flags

<table>

### Removed feature flags

<table>

### Behavioral changes

> [!NOTE]
> …

- <item>

Section order: Features → Fixes → Other → Deployment Changes. Subsections inside Deployment Changes appear in the order: New env vars → Deprecated env vars → Removed env vars → New feature flags → Removed feature flags → Behavioral changes.

A delta rc release uses the same shape — no preamble paragraph, no header pointing at the previous rc.

Return to the main conversation

Return a short summary — five lines or fewer. Include:

• The draft path (claude/release-notes/<tag>-draft.md).
• Counts of bullets per section after enhancement.
• Reclassifications that happened (e.g. "moved 2 from Other → Features, 1 from Other → Fixes, dropped 11 chat-e2e items").
• Items dropped (count, with one example).
• Whether a Deployment Changes section was added and which subsections.
• Any open questions for the user (env-var name disagreement between the migration guide/README and environment.config.ts/config-registry.constants.ts, ambiguous [Overlay] vs Features categorization, config-registry type: 'config' vs 'feature' classification of a new entry).

Example:

Drafted claude/release-notes/0.45.0-rc.55-draft.md. 4 Features, 6 Fixes, 2 Other (both [Overlay]). Reclassified 1 from Other → Features (feat(overlay) exposing subscribeToEvents) and dropped 14 chat-e2e items, 1 Storybook bump, and a revert+original pair on #6401. Folded 2 PRs (#6135, #6430) into one bullet on Issue #4696. Added Deployment Changes with New env vars (THEMES_CONFIG_HOST default changed) + Behavioral changes (aggressive history prefetch rolled back). One open: README says NEXT_PUBLIC_USE_MD_SIDEBAR_OVERLAY_BREAKPOINT, code reads process.env.NEXT_PUBLIC_USE_MD_SIDEBAR_BREAKPOINT — used the code name; flagged in editorial notes.

Safety rails

• Never edit GitHub. No gh release edit, no gh release create. Drafts only.
• Never invent items. Every kept bullet maps to a PR or a commit hash in the range.
• Never silently rename or drop a PR reference. The bullet ends with the canonical (Issue #<N>) (#<PR>) so links resolve on the release page.
• Verify canonical names from source, not from PR bodies or docs. Past PR descriptions and doc tables have used pre-rename names; environment.config.ts / config-registry.constants.ts in apps/chat-api/src/** is the source of truth (the frontend does not read env vars directly).
• Don't consolidate pre-release notes into the stable's notes unless the user explicitly asks — each rc tag has its own page.
• Match the terseness of the predecessor's notes. If they're one-liners, your bullets are one-liners. The user has flagged verbose drafts twice; defer to the established style.

Maintenance

Conventions drift as the project grows. If you notice a pattern in the raw CI notes that this skill doesn't handle (a new section the CI emits, a new conventional-commit scope that misroutes items, a recurring rewrite the user keeps asking for), surface it in your return summary and offer to update this SKILL.md. The user can confirm before any edit lands.
