| description | File a bug or feature request against @cyanheads/mcp-ts-core when you hit a framework issue. Use when a builder, utility, context method, or config behaves contrary to the documented API — not for server-specific application bugs.

When to Use
You've isolated a problem to @cyanheads/mcp-ts-core itself — not your server code, not a misconfiguration, not a missing peer dependency. Typical triggers:
- Framework builder (
tool(), resource(), prompt()) rejects valid input or produces incorrect output
createApp() or createWorkerHandler() fails on a valid config
Context properties (ctx.log, ctx.state, ctx.elicit, etc.) behave contrary to docs
- A utility from
/utils, /errors, /auth, /storage, /services returns wrong results or throws unexpectedly
- Type exports are incorrect or missing (compile error on documented usage)
- The definition linter (
bun run lint:mcp) produces false positives or misses real violations
For general gh CLI workflows outside issue filing (PRs, workflows, API access), see the github-cli skill.
Before Filing
- Confirm framework version —
bun pm ls @cyanheads/mcp-ts-core or check node_modules/@cyanheads/mcp-ts-core/package.json
- Check you're on latest —
bun outdated @cyanheads/mcp-ts-core. If behind, update and retest before filing.
- Isolate the issue — reproduce with a minimal handler or standalone script. Strip server-specific services, config, and dependencies. If the bug disappears when isolated, it's likely in your server code.
- Search existing issues — don't file duplicates:
gh issue list -R cyanheads/mcp-ts-core --search "your error message or keyword"
Writing Well-Structured Issues
Good issues are scannable, concrete, and self-contained — terse and fact-dense. Default to one or two sentences per bullet; if a bullet runs long, split it or cut it. These patterns apply to both bugs and features — the guidance targets any prose block (Description, Additional context, feature proposals).
- Lead with specifics. Name the tool, function, module, or symptom. "Currently
createApp() throws ConfigurationError when MCP_HTTP_PORT is set to 0" beats "There's a problem with the config." A reader should know what's broken or missing before the end of the first sentence.
- Embed library/service links on first mention.
[Hono](https://hono.dev/), [linkedom](https://github.com/WebReflection/linkedom). Link to the canonical repo or homepage so readers can verify the dependency and reach docs in one click.
- Use
owner/repo#N for cross-repo issue references. GitHub auto-renders them as linked references (e.g. cyanheads/pubmed-mcp-server#34). Bare #N only works for same-repo issues.
- Add a
Related: #N line near the top when the issue grows from prior context (discussions, other issues, PRs). Makes provenance clickable.
- Cite cross-references once per body. Link an issue/PR in
Related:, the description, or Additional context — not all three. The reader sees them all; redundant linking dilutes signal.
- Lead design sections with a philosophy sentence. Bold a short principle before the tradeoff details — e.g. "Philosophy: fail fast on config errors, degrade gracefully on runtime errors." Establishes the lens for the rest of the section.
- Prefer Markdown tables for comparisons. When showing options, tiers, strategies, or tradeoffs — tables are the highest-density format for scanning N rows × M attributes.
- Separate
### Scope from ### Out of scope. The latter is as important as the former — it pre-empts scope-creep debates in comments and signals you've thought about the boundaries.
- Use
Depends on: owner/repo#N to declare ordering explicitly when implementation is blocked on another issue landing first.
- Cut what dilutes the signal. Mechanism walkthroughs (link the PR or doc instead), ceremonial framings ("This issue covers…"), conversation references ("as discussed", "per offline"), and kitchen-sink Additional context blocks. If a paragraph isn't pulling weight, drop it.
- Skip collaborator-framing sign-offs. Lines like "Happy to open a PR", "let me know if you'd like", "willing to contribute", "if that's the preferred flow" read as noise. A PR link beats an offer; if you're the maintainer filing against your own repo, the offer is redundant. End the body at the last substantive point.
Redact Before Posting
GitHub issues are public. Do not include secrets, credentials, API keys, or tokens. Redact sensitive values from env vars, headers, and logs before submitting. Replace with obvious placeholders: REDACTED, sk-...REDACTED. Do not rely on partial masking — partial keys can still be exploited.
Filing a Bug
The repo has YAML form issue templates. Use --web to open the form in the browser (preferred when available), or pass --title + --body for non-interactive use.
Browser (interactive)
gh issue create -R cyanheads/mcp-ts-core --template "Bug Report" --web
CLI (non-interactive)
Structure the --body to match the template's form fields:
gh issue create -R cyanheads/mcp-ts-core \
--title "bug(scope): concise description" \
--label "bug" \
--assignee "@me" \
--body "$(cat <<'ISSUE'
### mcp-ts-core version
0.1.29
### Runtime
Bun
### Runtime version
Bun 1.3.x
### Transport
stdio
### OS
macOS 15.x
### Description
Brief explanation of the bug — what you expected vs what happened.
### Reproduction
```ts
import { tool, z } from '@cyanheads/mcp-ts-core';
export const broken = tool('broken_example', {
description: 'Minimal repro.',
input: z.object({ id: z.string().describe('ID') }),
output: z.object({
name: z.string().describe('Name'),
extra: z.string().optional().describe('Optional field'),
}),
async handler(input, ctx) {
return { name: 'test' }; // omitting optional field causes validation error
},
});
```
### Actual behavior
```
Error: Output validation failed: ...
```
### Expected behavior
Omitting an optional output field should pass validation.
### Additional context
Any workarounds, related issues, or observations.

Labels
Every issue needs exactly one primary label. Stack secondary labels on top when applicable.
Primary (required — pick one):
| Label | When |
|---|
bug | Something broken |
enhancement | Feature request or improvement |
documentation | Documentation is wrong, missing, or misleading |
Secondary (optional — stack on top of primary):
| Label | When |
|---|
regression | Worked before, broken after an update |
performance | Memory, CPU, latency, or resource usage |
security | Vulnerability, CVE, or hardening work |
breaking-change | Fix/feature will break public API; requires a major bump |
surplus-token-idea | Worth exploring when token budget allows |
Combine labels: --label "bug" --label "regression".
Attaching logs or stack traces
For long output, write to a file and attach:
bun run rebuild && bun run start:stdio 2>&1 | head -100 > /tmp/mcp-error.log
gh issue create -R cyanheads/mcp-ts-core \
--title "bug(transport): stdio crashes on large payload" \
--label "bug" \
--assignee "@me" \
--body-file /tmp/mcp-error.log
gh issue comment <number> -R cyanheads/mcp-ts-core --body-file /tmp/mcp-error.log
Filing a Feature Request
Browser (interactive)
gh issue create -R cyanheads/mcp-ts-core --template "Feature Request" --web
CLI (non-interactive)
Template below demonstrates the richer structure. Omit sections you don't need — simple requests don't require Flow / Design / Dependencies blocks.
gh issue create -R cyanheads/mcp-ts-core \
--title "feat(scope): concise description" \
--label "enhancement" \
--assignee "@me" \
--body "$(cat <<'ISSUE'
Concrete statement of what's currently missing or broken in the framework. Name the specific builder, utility, context method, or config field. Two or three sentences — the reader should know the gap before the end of the paragraph.
Related: #N
## Proposal
What you want the framework to do, in one paragraph. Link external libraries on first mention: [lib name](https://github.com/owner/repo). Include a short justification — what this gives us that we don't have today.
### Proposed API
```ts
import { withRetry } from '@cyanheads/mcp-ts-core/utils';
const result = await withRetry(() => fetchExternal(url), {
maxAttempts: 3,
backoff: 'exponential',
});
```
### Flow (optional)
Ordered steps — e.g. `trigger → resolve → fetch → degrade`. Useful when the change spans multiple phases or fallbacks.
### Design / Tradeoffs (optional)
Philosophy: **one-line principle in bold.**
| Option | Strengths | Weaknesses |
|:---|:---|:---|
| A | ... | ... |
| B | ... | ... |
### Scope
- Files or modules touched
- New exports, env vars, or config keys
- Tier (Tier 1 core / Tier 2 standard / Tier 3 optional peer dep)
### Out of scope
- What we're deliberately not doing
- Adjacent work that belongs in a separate issue
### Dependencies (optional)
- Depends on: owner/repo#N
### Alternatives considered
What you tried or evaluated instead, and why it didn't fit.
