# Agent specs
|
||||
|
||||
The published agent definitions this deployment ships, one file each, as §7
|
||||
describes: *"Adding an agent is a data change."* Nothing in `internal/runtime`
|
||||
knows any of these files exist.
|
||||
|
||||
## Where these came from
|
||||
|
||||
They are the nine agents in `krow-demo/src/agents/`, which is where the product
|
||||
authored them and where they still live for the frontend's registry. These are
|
||||
not copies — they are the same definitions with two blocks the frontend has no
|
||||
field for:
|
||||
|
||||
- **`tools:`** — the registry names this agent may call. The frontend has no
|
||||
tool layer, so its specs carry none; the backend has seventeen tools and an
|
||||
agent that names none of them can only talk.
|
||||
- **`sources:`** — the knowledge corpora it may retrieve from. Named `sources`
|
||||
rather than `knowledge` because the shipped product already uses
|
||||
`knowledge:` for an author's notes. See the note on
|
||||
`runtime.Agent.KnowledgeSources`; the collision is flagged, not settled.
|
||||
|
||||
An unknown frontmatter key is ignored by both parsers, so these files still
|
||||
load in the frontend registry unchanged.
|
||||
|
||||
## Publishing
|
||||
|
||||
make import-agents ORG=<slug>
|
||||
|
||||
Idempotent: re-running updates the definitions in place rather than
|
||||
duplicating them.
|
||||
|
||||
## The rule these files exist to keep
|
||||
|
||||
If adding an agent here ever requires editing code in `internal/runtime`, that
|
||||
is a missing platform capability, not a special case. §7 and I6 both say so, and
|
||||
the loop has no branch that asks which agent it is running.

# Activity Agent
|
||||
|
||||
## Instructions
|
||||
|
||||
Answer about what has happened in this workspace: which events, by which
|
||||
account, and when.
|
||||
|
||||
Report something as unusual only when it genuinely departs from the pattern in
|
||||
the log. Flagging ordinary activity trains the reader to ignore the flag.
|
||||
|
||||
This agent carries no skills of its own; Activity answers from its own page
|
||||
reader.
|
||||
|
||||
## Purpose
|
||||
|
||||
- Report recent workspace events and who performed them.
|
||||
- Surface activity that departs from the usual pattern.

# Analytics Agent
|
||||
|
||||
## Instructions
|
||||
|
||||
Answer about performance over time: how hiring is trending, where the funnel
|
||||
converts and where it leaks, and how departments compare.
|
||||
|
||||
Explain the figures the Analytics page is already showing rather than producing
|
||||
different ones. When a movement is small enough to be noise, say so rather than
|
||||
narrating it as a trend.
|
||||
|
||||
## Purpose
|
||||
|
||||
- Explain hiring trend and conversion.
|
||||
- Compare department performance, and identify where the funnel loses people.

# Candidates Agent
|
||||
|
||||
## Instructions
|
||||
|
||||
Answer about the people who have applied: who is waiting, who scores well, who
|
||||
has not been screened, and where the pipeline is losing candidates.
|
||||
|
||||
Quote a score only where one has been computed. An unscored candidate is
|
||||
unscored — say so rather than implying a low score.
|
||||
|
||||
Never advance, decline or hire a candidate without being asked to.
|
||||
|
||||
## Purpose
|
||||
|
||||
- Report who is waiting on a decision, and who is strongest.
|
||||
- Find candidates matching what a role asks for.

# Control Center Agent
|
||||
|
||||
## Instructions
|
||||
|
||||
Answer about the state of the workspace as a whole: what is urgent, where the
|
||||
funnel is losing people, and what the reader should do next.
|
||||
|
||||
Read the figures the Control Center already shows rather than recomputing them,
|
||||
so the answer and the dashboard beside it can never disagree.
|
||||
|
||||
This agent carries no skills of its own. That is deliberate — the Control
|
||||
Center answers from its own page reader, and inventing skills to fill the list
|
||||
would promise capabilities that do not exist.
|
||||
|
||||
## Purpose
|
||||
|
||||
- Say what needs attention across the workspace.
|
||||
- Explain where the hiring funnel is losing candidates.

||||
This is the record after the decision, not the pipeline before it. A question
|
||||
about people still being considered belongs to Candidates.
|
||||
|
||||
This agent carries no skills of its own. Hired History answers from its own
|
||||
page reader, and a placeholder skill would promise a capability that does not
|
||||
exist.
|
||||
|
||||
## Purpose
|
||||
|
||||
- Report recent hires, and how quickly they were made.
|
||||
- Compare hiring outcomes across departments.

# KROW Forge Agent
|
||||
|
||||
## Instructions
|
||||
|
||||
Answer about the training library and what the workforce has proved: which
|
||||
paths exist, which are published, what a challenge checks, and where coverage
|
||||
is thin.
|
||||
|
||||
A skill in Forge is something a person learns and is verified in. It is not an
|
||||
Owliver capability — never describe the two as the same thing.
|
||||
|
||||
Never publish or archive training without being asked to.
|
||||
|
||||
## Purpose
|
||||
|
||||
- Report what the training library holds and what is live.
|
||||
- Identify gaps between what roles need and what is taught.

# Krow Workforce Agent
|
||||
|
||||
## Instructions
|
||||
|
||||
Answer from the records this workspace holds, for the page the reader is on.
|
||||
|
||||
State a figure only where a skill has read it. When a reading needs a position
|
||||
or a candidate and none is open, ask which one rather than choosing one.
|
||||
|
||||
Covering every page is not permission to read every page at once. The page in
|
||||
front of the reader decides what is in reach; a question that belongs somewhere
|
||||
else should be answered by naming where it belongs, not by reaching for it.
|
||||
|
||||
## Purpose
|
||||
|
||||
- Answer questions that span more than one Krow domain.
|
||||
- Stand in on pages whose own agent carries no skills.
|
||||
- Hand a question that clearly belongs to another page back to that page.

## Instructions
|

|
||||
Answer about the roles this workspace has open: how they are filling, which are
|
||||
starved of applicants, and what a role still needs before it can be published.
|
||||
|
||||
When a question names a role, answer about that role. When it does not and one
|
||||
is open on the page, answer about that one. When neither is true, ask which.
|
||||
|
||||
Never create or publish a position without being asked to.
|
||||
|
||||
## Purpose
|
||||
|
||||
- Report how open roles are filling, and which are at risk.
|
||||
- Help specify a new role and its screening weights.

Answer about the people this workspace already knows: who is in the pool, what

they are verified in, and who could be placed now.

This is supply, not applicants. Someone in the pool has not applied to anything

- **`query` present** — ranked against the static catalogue in `internal/owliver`.

No table is read, no transaction is opened and no model is called: the panel

issues one of these per keystroke, so the whole answer is a few string

comparisons.

- **`query` absent** — ranked against **the organization's actual state**, read
|

from PostgreSQL in one statement: how many positions are unfinished drafts,
|

how many active roles nobody has applied to, how many candidates are waiting
|
||||
on a score, how many interviews carry a flag. This is one query per opened
|

panel, and it is what makes a suggestion react to the data — creating a
|

position changes what comes back next time it is asked.
|

|
||||
Ranking here is by **tier first, count second**. Each reading declares how
|
||||
much its subject matters when it is happening at all — a role nobody has
|

applied to outranks a queue of unscored candidates, which outranks a
|

headcount — and the count only orders readings inside a tier. Weight × count
|

would mean the largest pile always won, so a workspace with forty
|
||||
applications and one abandoned role would be asked about the forty. A count

of zero scores nothing whatever its tier, so a page with nothing to report is

offered nothing rather than an urgent-sounding question about an empty set.
|

Only counts are read. Nothing that could name a record, a person or an id

reaches the ranking, and a talent caller's counts are never read at all: every

figure behind a highlight is organization-wide, and their rows are narrowed by

the policy table.

## 1. What is running now
|
||||
|
||||
`954ba90` — or equivalently `cadea4b`, the merge commit whose tree is byte-identical.
|
||||
|
||||
Established from the outside, without credentials:
|
||||
|
||||
| Observation | Command | Conclusion |
|
||||
| --- | --- | --- |
|
||||
| Preflight echoes the origin and `Access-Control-Allow-Credentials` | `OPTIONS /api/v1/job-postings -H 'Origin: https://platform.krowforce.com'` → `204` | ≥ `954ba90` — that header was added there and is absent at `7d12ebe` |
|
||||
| Session cookie is `SameSite=Lax` while a CORS allowlist is configured | `POST /api/v1/auth/logout` → `Set-Cookie: … Secure; SameSite=Lax` | < `b6f8655` — from that commit a configured allowlist forces `SameSite=None` |
|
||||
| `routeOwliver` absent from `server.go` at `cadea4b` | `git show cadea4b:…/server.go \| grep s.route` | `GET /api/v1/owliver/suggestions` is not registered |
|
||||
|
||||
**52 endpoints deployed. 53 at `HEAD`.** The missing one is the Owliver
|
||||
suggestions route, which is the 404 the frontend sees.
|
||||
|
||||
`/health` returns `{"status":"ok"}` — not `degraded` — so the remote schema is
|
||||
present and not dirty.
|
||||
|
||||
## 2. What is being deployed
|
||||
|
||||
`b6f8655`, which is `HEAD` and is already `origin/main`. Nothing needs pushing.
|
||||
|
||||
**Plus one commit** prepared here — see §4. It is required: without it this
|
||||
deploy silently removes the only CSRF protection the API has.
|
||||
|
||||
Local working-tree changes (the database-backed Owliver suggestion context) are
|
||||
**not** part of this deploy and are not on any branch. They do not reach the
|
||||
host, which builds from `origin/main`.
|
||||
|
||||
### Verified before shipping
|
||||
|
||||
| Check | Result |
|
||||
| --- | --- |
|
||||
| `go build ./...`, `go vet ./...` | clean |
|
||||
| `GOOS=linux GOARCH=amd64 CGO_ENABLED=0 go build ./cmd/api` | 17 MB static ELF, builds clean |
|
||||
| `go test ./...` | 8/8 packages pass, against real migrated PostgreSQL |
|
||||
| Migration delta `cadea4b → HEAD` | **none** — `git diff cadea4b HEAD -- migrations/` is empty |
|
||||
| Config compatibility | no new validation; the new binary accepts a strict superset of what the host is configured with |
|
||||
|
||||
**No schema step.** This is a binary-only rollout.
|
||||
|
||||
## 3. What changes in behaviour
|
||||
|
||||
Beyond the new route, `b6f8655` fixes three things already broken in production:
|
||||
|
||||
- **`POST /api/v1/ai-interviews`** becomes transactional — it sets
|
||||
`interview_id`, advances the application to `interview` and copies the score.
|
||||
The deployed version writes only the interview, and the frontend deliberately
|
||||
does not patch the application afterwards, so **completing an interview
|
||||
currently leaves the candidate un-advanced with nothing to show it.**
|
||||
- **`POST /api/v1/job-postings/{id}/assignments`** may now file an application
|
||||
for a worker placed from the talent pool who never applied. It currently
|
||||
cannot, so those assignments fail.
|
||||
- **`serverSupplies`** now checks the caller's role. Previously a talent-only
|
||||
derived column was treated as server-supplied for every role, so an
|
||||
**operator** creating a job application without an email passed validation and
|
||||
hit a NOT NULL violation — **a 500 where the contract promises 422.**
|
||||
|
||||
## 4. The required extra commit — cookie posture
|
||||
|
||||
`b6f8655` alone derives `SameSite` from whether a CORS allowlist is configured:
|
||||
non-empty ⇒ `None`. On this host the allowlist *is* non-empty, so deploying it
|
||||
as-is flips the session cookie from `Lax` to `None`.
|
||||
|
||||
**`SameSite` is the only CSRF protection this API has.** There is no CSRF token.
|
||||
|
||||
The derivation is wrong for this topology, because CORS and SameSite answer
|
||||
different questions:
|
||||
|
||||
- **CORS** is about **origin**. `platform.krowforce.com` → `mcp.krowforce.com`
|
||||
is cross-origin, so the allowlist is genuinely required. Confirmed live: that
|
||||
origin returns `204` with the origin echoed; an unlisted origin returns `403`.
|
||||
- **SameSite** is about **site**. Both share the registrable domain
|
||||
`krowforce.com`, so they are **same-site** and a `Lax` cookie is already sent
|
||||
on those requests.
|
||||
|
||||
So the correct configuration is *CORS on, `SameSite=Lax`* — a combination
|
||||
`b6f8655` cannot express.
|
||||
|
||||
The commit makes an explicit `HTTP_COOKIE_SAMESITE` authoritative and leaves the
|
||||
CORS-derived value as the default when it is unset. It also closes a trap:
|
||||
`config.Load` has always parsed and validated that variable, and nothing read
|
||||
it, so a deployment that set it saw it silently ignored.
|
||||
|
||||
```
|
||||
internal/config/config.go unset is "" rather than defaulting to "lax"
|
||||
internal/httpserver/auth.go explicit value wins; allowlist decides the default
|
||||
internal/httpserver/samesite_test.go the full matrix, pinned
|
||||
```
|
||||
|
||||
`docker-compose.yml` already passes `HTTP_COOKIE_SAMESITE: ${…:-lax}`, so a
|
||||
compose deploy keeps `Lax` without any `.env` change.
|
||||
|
||||
> **Do not empty `HTTP_CORS_ORIGINS`.** It looks like a way to keep `Lax`
|
||||
> without a code change, and it would take `platform.krowforce.com` offline —
|
||||
> that frontend calls the API cross-origin from the browser.
|
||||
|
||||
## 5. Rollout
|
||||
|
||||
Migrations first, then the binary — the order `docker-compose.yml` already
|
||||
encodes through `depends_on: service_completed_successfully`. There is nothing
|
||||
to migrate this time, but the step is a no-op rather than something to skip.
|
||||
|
||||
```sh
|
||||
# On the host, from the repository root
|
||||
git fetch origin && git checkout b6f8655 # or the extra commit from §4
|
||||
cd infrastructure
|
||||

||||
docker compose up -d --no-deps migrate # exits 0, nothing to apply

|
||||
```
|
||||
|
||||
`"endpoints":53` in the startup log is the single fastest confirmation that the
|
||||
right binary is running.
|
||||
|
||||
## 6. Verification
|
||||
|
||||
```sh
|
||||
KROW_EMAIL=… KROW_PASSWORD=… ./scripts/verify-deployment.sh
|
||||
```
|
||||
|
||||
Read-only by default. Add `--write` to prove the write path reaches PostgreSQL;
|
||||
it creates one posting with `status: draft`, which is invisible to talent — and
|
||||
permanent, because `JobPosting` has no `DELETE`.
|
||||
|
||||
It checks, in order: `/health` and whether the schema reads `degraded`; login
|
||||
and the issued cookie; the caller's `role` (a `talent` role explains almost every
|
||||
403); `GET /owliver/suggestions` as the version discriminator; that
|
||||
`/api/v1/positions` still `404`s; `GET /job-postings`; both suggestion modes and
|
||||
the 3-item cap; and the `SameSite` attribute actually being served.
|
||||
|
||||
Exit status is the number of failures, so it can gate a rollout.
|
||||
|
||||
### The resource is `job-postings`
|
||||
|
||||
`/api/v1/positions` has never existed in this API. Every `/positions` in the
|
||||
frontend is a React Router **UI** route. Two tests assert the phantom stays
|
||||
absent — `TestThereIsNoPositionsResource` and the script's own check — so nobody
|
||||
"fixes" a future 404 by adding a duplicate resource.
|
||||
|
||||
## 7. Rollback
|
||||
|
||||
The previous image is still on the host.
|
||||
|
||||
```sh
|
||||
docker compose down api
|
||||
git checkout cadea4b
|
||||
docker compose build api && docker compose up -d --no-deps api
|
||||
```
|
||||
|
||||
No schema change means rollback is clean: nothing to reverse, and the old binary
|
||||
runs against the current schema unchanged.
|
||||
|
||||
## 8. Separately — the deployed frontends are not reaching the API
|
||||
|
||||
Found while verifying, out of scope for this deploy, and more severe than the 404.
|
||||
|
||||
`platform.krowforce.com` is built with
|
||||
`VITE_API_BASE_URL=https://mcp.krowforce.com/api/v1` — an absolute cross-origin
|
||||
URL. The repository's own `.env` warns against this at length, and
|
||||
`httpClient.js` has a guard for it that is compiled out of production builds, so
|
||||
it fails silently.
|
||||
|
||||
`app.krowforce.com` is worse off: its origin is **not** on the backend's
|
||||
allowlist (`403` at preflight), and its bundle carries neither `auth/login` nor
|
||||
any reference to the API host.
|
||||
|
||||
Both hosts also serve their SPA for `/api/v1/*` — `GET /api/v1/me` on either
|
||||
returns `index.html` with status `200`. The shipped `nginx.conf` has no `/api`
|
||||
proxy at all, and `try_files $uri $uri/ /index.html` swallows every API path.
|
||||
|
||||
The fix is a `/api` and `/health` `proxy_pass` in the frontend's nginx plus a
|
||||
rebuild with `VITE_API_BASE_URL=/api/v1`, which is what the same-origin design
|
||||
assumes. That is a frontend deployment change and belongs in its own rollout.

// STRUCTURE — no forged tag can be parsed as a marker — and mitigated, not

//
|

// 1. **Hybrid.** Dense and BM25, fused with RRF. Not dense-only "for

// convenience" — semantic search is bad at exact terms, and a workforce
|
||||
// corpus is full of them: a shift code, a certification name, a venue. Not
|
||||
// keyword-only either, which is the failure this deployment could most
|
||||
// easily have shipped, having no embedding credential.
|
||||
// 2. **Permission as a pre-filter.** The same predicate goes into BOTH
|
||||
// queries' WHERE clauses. This is I2, and it is not a style choice: rank
|
||||
// first and drop afterwards and the forbidden rows leak through the shape
|
||||
// of what is left — a short result set, a top-3 with a hole in it, a
|
||||
// confidence that tracks documents the caller cannot see.
|
||||
// 3. **Citable results.** Every chunk comes back with the ids needed to point
|
||||
// at it, so a response can cite and the surface can link.
|
||||
//
|

|

// naive reading of it is not safe, and the difference is the whole of this
|

// file.
|
||||
//
|
||||
// The naive reading is a boolean: ask, get a yes, run. That version has a hole
|
||||
// wide enough to drive a payroll through. A person approves "assign Maya Chen
|
||||
// to Friday's bar shift"; the model, on the next turn, calls the same tool with
|
||||
// a different worker and the same yes still applies. Nothing in a boolean
|
||||
// distinguishes those two calls, so the approval a person gave to one becomes
|
||||
// an approval they never gave to the other.
|
||||
//
|
||||
// So a confirmation here is a *binding*, not a flag. A token is issued against
|
||||
// a fingerprint of exactly what was described to the person:
|
||||
//
|
||||
// tool name + canonical inputs + principal + tenant
|
||||
//
|
||||
// and it validates only against a call carrying that same fingerprint. Change
|
||||
// the worker, change the shift, change the caller, cross a tenant — each of
|
||||
// those produces a different fingerprint and the token is refused. It is also
|
||||
// single-use, so one approval buys exactly one write.
|
||||
//
|
||||
// WHY THE RUN IS RECORDED BUT NOT MATCHED
|
||||
//
|
||||
// The fingerprint originally included the run id, which is the tighter thing to
|
||||
// do and was wrong. A confirmation exists precisely so that a run can END and a
|
||||
// person can be asked; the run that resumes afterwards is a new run with a new
|
||||
// id, so matching on it made every token unredeemable — the mechanism refused
|
||||
// exactly the case it was built for.
|
||||
//
|
||||
// The run id is still stored, because "which conversation proposed this write"
|
||||
// is worth being able to answer. It is not part of the match, and what covers
|
||||
// the gap is the rest of the binding: the arguments are identical, so a token
|
||||
// replayed in a later run authorises the very write it described; the TTL bounds
|
||||
// how stale the surrounding facts can be; single-use bounds it to one; and the
|
||||
// handler re-checks the world before writing. What a run-scoped match would have
|
||||
// added on top of that is protection against a surface that hands back a token
|
||||
// the user never clicked — which is a bug in the surface, not a hole a token
|
||||
// format can close.
|
||||
//
|
||||
// The second half is Confirmer. A person cannot approve what they cannot read,
|
||||
// and `{"job_posting_id":"3f2b...","worker_profile_id":"91ac..."}` is not
|
||||
// something anyone can approve honestly. Every write tool must render a plain
|
||||
// language description of what will happen — and must do it *behind the same
|
||||
// authorization as the write itself*, because a renderer that resolves a name
|

// the caller may not see has leaked that name in the course of asking whether

# Documents agents can read
|
||||
|
||||
Markdown files, one per document, ingested by:
|
||||
|
||||
make ingest ORG=<slug>
|
||||
|
||||
Each file declares who may read it in its front matter. **That declaration is
|
||||
required** — §5 says a chunk without ACL metadata is rejected at ingest, and the
|
||||
reason is worth stating: an empty audience is not "private", it is a row the
|
||||
permission filter can never match. A document that indexed to nothing looks
|
||||
ingested, reports a chunk count, and is silently unreachable forever.
|
||||
|
||||
```markdown
|
||||
---
|
||||
source: policy_docs
|
||||
audience: tenant # everyone in the organization
|
||||
title: Staff Handbook
|
||||
---
|
||||
```
|
||||
|
||||
`audience` accepts:
|
||||
|
||||
| value | who can read it |
|
||||
|---|---|
|
||||
| `tenant` | everyone in the organization |
|
||||
| `role:admin`, `role:employer`, `role:talent` | one role (comma-separate for several) |
|
||||
| `email:someone@example.com` | one person, by email |
|
||||
|
||||
`source` is the corpus name. An agent spec's `sources:` block names which
|
||||
corpora it may retrieve from, so this is part of the permission story rather
|
||||
than a label: an agent granted `policy_docs` does not thereby gain
|
||||
`worker_notes`.
|
||||
|
||||
Re-ingesting is safe. A document whose content and audience are unchanged is a
|
||||
no-op; changing either rewrites its chunks, because the chunks carry a copy of
|
||||
the audience and a permission change that did not reach them would be a
|
||||
permission change that did not happen.

budget for this year is capped at four percent of the wage bill across the
|
||||
venue, and individual awards are expected to sit between zero and six percent.
|
||||
|
||||
An award above six percent needs a written case and sign-off from the regional
|
||||
lead. The cap is on the total, not on any one person — funding an exceptional
|
||||
award means funding it from the same pot as everyone else's.

# Promotion to supervisor
|
||||
|
||||
A promotion case rests on three things: sustained attendance, demonstrated
|
||||
judgement under pressure, and a willingness to be accountable for other people's
|
||||
shifts. Length of service is not one of them.
|
||||
|
||||
Candidates should have covered at least forty shifts and have no unresolved
|
||||
lateness conversation in the preceding quarter.
|
||||
|
||||
# What not to discuss
|
||||
|
||||
Individual awards are confidential until communicated. Discussing another
|
||||
person's band, or the reasoning behind it, outside the review panel is a
|
||||
disciplinary matter.
