Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Skills and Scars for AI agents - your agent records its failures and never repeats them.
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.
Pick the AI app you use, then copy the settings.
KIRA_TELEMETRY, KIRA_TELEMETRY_URL, KIRA_HOME, KIRA_PRO_KEYValues marked secret are keys to your account. Never share them or paste them into a chat.

Every failed retry, every exception, every *"wait — we hit this exact wall last week"* is knowledge your agent throws away when the session ends. Kira keeps it. One MCP install and your agent records what burned it (a *scar*), sees its scars before it works again, and stops paying for the same mistake twice.
Privacy by design. Personal scars and the lookup-miss log are local-only — never uploaded, on any tier. Community telemetry is opt-in and redacts secrets, paths, and identifiers locally before write AND server-side before storage. Run
npm run demo:privacyto see exactly what leaves your machine. Full wire format and opt-out in PRIVACY.md.
Add this snippet to your MCP host config:
{
"mcpServers": { "kira": { "command": "npx", "args": ["-y", "kira-mcp@latest"] } } }
That's it. Your agent now has Kira.

Monday agent gates a merge on: npm run build 2>&1 | tail -1
exit code comes from tail, not the compiler → broken code reaches main └─ kira_record_failure( title: "build gate bypassed: exit code swallowed by pipe to tail", instead: "never gate on a piped command without pipefail")
Tuesday new session, same machine └─ session brief: "⚠ You have been burned by this before: never gate on a piped command without set -o pipefail" agent writes the gate correctly. Zero repeats. Zero wasted tokens.
Not a hypothetical — this is the actual first scar in the database, recorded by the agent that built this feature, about a mistake it made *while building it*. The next three scars came the same day. The loop works on day one, for a single user, with zero network effects required. FLYWHEEL.md documents the full improvement loop.
| Tool | What it does | |
|---|---|---|
| Personal memory | kira_record_failure | Capture a retry/exception as a personal scar (local-only) |
kira_personal_brief | Session-start brief of your latest scars — start work already knowing where you got burned | |
kira_premortem | Failure heat-map for a goal *before* starting — "here's where this kind of task has burned you" | |
| Catalog | kira_lookup | Keyword → proven instructions + failure warnings. On a miss, returns scored near_skills / near_scars instead of a shrug |
kira_get | Fetch full step-by-step instructions by ID | |
kira_route | Goal → ordered plan with a skill per step | |
| Community | kira_share_scar | Promote a personal scar into a community submission (sanitized; nothing uploads without your click) — earns contributor status |
| Feedback | kira_report | Report success/retry/failure → feeds the quality loop |
kira_consent / kira_status | Telemetry consent + one-call introspection |
Auto-firing: you don't call Kira — Kira's MCP instructions tell your agent when to. Japanese queries are first-class (CJK bigram matching).
A lookup miss is not a dead end — it's demand data. Kira returns the closest scored matches, records the miss locally (with *what almost matched*), and the weekly flywheel digest turns repeated misses into alias fixes and new-skill candidates. The catalog learns what people actually ask for.
38 community skills across deploy / database / auth / payments / UI / testing / CI / infra / mobile / CMS, and 45 community scars — real failure patterns like *"Vercel deploy succeeds but the app crashes: missing env vars"* or *"Auth.js v5 signIn imported from the wrong side"*. kira_route turns a goal ("build a web app") into an ordered plan with the right skill and scars per step.
Community scars are where personal scars graduate to — and the flow is live. Ask your agent to run kira_share_scar(scar_id): it re-sanitizes your personal scar, generalizes it, and hands you a prefilled submission link (nothing uploads until you click). An intake bot validates the JSON; a human reviews the content; on merge it ships to every Kira user. Prefer forms? Submit a scar directly.
Every accepted scar earns contributor status — sharing is how you get the fresh feed for free (see Contributing below).

| Setup | Copy per project | Install once |
| Failure memory | You write it by hand, if you remember | kira_record_failure — captured at the moment it happens |
| Recall | You re-read it, if you remember | Surfaced automatically at session start / task start |

There are excellent memory servers (knowledge graphs, session recall, context handoff). Kira is deliberately narrower:
mistake → instead, severity, recurrence count. A pre-task heat-map (kira_premortem) exists only because the data is failures.hit_count — the corpus learns which walls actually get hit, and honest counts are enforced by review.If you need general episodic memory, run one of those servers *alongside* Kira — they don't compete for the same job.
Personal scars (~/.kira/personal-scars/) and the miss log (~/.kira/misses.log) are local-only and never uploaded. Community telemetry is separate and consent-gated:
Mode (KIRA_TELEMETRY env, or kira_consent MCP tool) | What leaves your machine |
|---|---|
off | Nothing. Local log only. |
basic *(default)* | Anonymous core: skill ID, status, anonymous UUID, kira version, OS family, Node major version, free/pro tier. No free text. |
full | Same as basic plus sanitized note / context (secrets, paths, identifiers redacted). |
Full schema, redaction rules, retention, and opt-out instructions: [PRIVACY.md](./PRIVACY.md).
| Env var | Default | Purpose |
|---|---|---|
KIRA_TELEMETRY | (unset → basic) | Override consent level for this process: off, basic, full. |
KIRA_TELEMETRY_URL | https://kira-telemetry.workers.dev/v1/reports | Endpoint for batch upload. |
KIRA_HOME | ~/.kira | Where consent state, personal scars, miss log, and flywheel output live. |
KIRA_KEY | (unset → free tier) | Contributor / supporter key — unlocks the fresh community feed. |
KIRA_REMOTE_URL | (unset → no network) | Opt-in corpus feed URL for the free tier (90-day-delayed commons). |
The corpus is MIT and everything in it eventually becomes free. Freshness is the only premium — failure knowledge decays as models retrain, so the newest scars carry the value:
| Fresh community feed | How | |
|---|---|---|
| Contributor | ✅ free | One accepted scar = 12 months (kira_share_scar → merge → key). First 1,000 contributors: permanent. |
| Supporter | ✅ paid | Sponsor the project → supporter key. Funds human review of every submission. |
| Free | 90 days later | Base corpus ships with npm; delayed commons feed available opt-in. Local features + privacy guarantees are free forever, on every tier. |
Currently in grace mode: the fresh feed is open to everyone until the corpus reaches 100 community scars. Full policy: RECIPROCITY.md.
The first 1,000 contributors get permanent free access to all Kira features (fresh feed included) — see the reciprocity table above.
See CONTRIBUTING.md for how to add Skills and Scars.
