# Linkedin Batch Drain Codex

> Codex-conducted LinkedIn batch drain for Liam's early-career SWE search. Use when Liam says $linkedin-batch-drain-codex or wants Codex chat to act as a persistent monitor that first discovers the requested target of fresh non-duplicate LinkedIn postings, normally 40 when Liam asks for a 40-role batch, then tailors verified resumes efficiently with no-browser workers, and finally applies sequentially in ATS-friction order while submitting high-confidence applications and parking only true blockers.

# LinkedIn Batch Drain Codex

Batch-first LinkedIn drain: Codex chat is the conductor and monitor. It first
collects the requested target of fresh non-duplicate LinkedIn early-career SWE
postings, tailors resumes efficiently, then applies one browser form at a time
in the easiest ATS order. When Liam asks for 40 roles, the target is 40 usable
non-duplicates; do not treat 20 as enough.

This is intentionally different from the older one-posting-at-a-time weekly
flow. Use the weekly/conducted skills for conservative one-stage drains; use
this skill when Liam wants a large batch, efficient tailoring, and a persistent
chat conductor.

## Source Files

Read these before running:

```text
skills/linkedin-early-career-weekly/OPERATING_CARD.md
skills/linkedin-easy-apply-nodriver/references/application-defaults.md
skills/resume-tailor/SKILL.md
skills/finish-app-script/OPERATING_CARD.md
skills/linkedin-batch-drain-codex/references/batch-state.md
```

Use `finish-app-script/OPERATING_CARD.md` only for live-form guardrails,
standing-answer safety, upload handling, and submit confidence. Do not invoke
the finish-app queue and do not write `/tmp/fa_script_run_state.json`.

## Persistent Goal

When goal tools are available, create or continue a pursuing goal before
launching browser work, monitor loops, tailor workers, or application attempts.
Use this objective:

```text
Drain the requested LinkedIn batch with Codex as persistent monitor: discover the requested number of fresh non-duplicate early-career SWE postings, defaulting to 40 when Liam asks for 40, tailor verified resumes, then submit every high-confidence application with confirmation evidence in ATS-friction order while parking only true blockers.
```

Completion condition:

> The batch is complete when the requested usable target, normally 40 when Liam
> asks for 40, has been reached with fresh non-duplicate early-career LinkedIn
> software-engineer postings, or when every configured search/freshness
> expansion has been exhausted and exact search saturation is recorded. Only
> then tailor verified one-page resumes, then drive every usable posting to a
> terminal state: submitted with confirmation evidence, recorded as a precise
> manual blocker, marked already-applied/duplicate, or archived with a reason.
> Submit high-confidence applications when the tailored resume is verified, all
> required answers are truthful/standing-answer covered, and no true blocker
> remains. Apply sequentially in ATS-friction order, keep the markdown tracker
> and visualizer cache reconciled, stop early only on final search-space
> saturation, systemic browser/auth/rate-limit blocker, or explicit user stop,
> and never run more than one browser actor at a time.

Do not close the goal until the condition is met, a systemic blocker is hit, or
Liam explicitly stops the run.

## Batch-First Gate

Discovery is a hard gate. Do not begin tailoring or application work merely
because the first search pass is thin.

- If Liam asks for a number, set `batch.usableTarget`,
  `runPolicy.batchTarget`, and `runPolicy.maxJobs` to that number. For "40
  total", use 40.
- Collect usable, non-duplicate postings until `batch.usableKeys.length`
  reaches the target.
- If a last-24-hours search saturates below target, expand to the matching
  last-week search and continue walking every configured page before any
  tailoring/application phase.
- If the last-week pass still has fewer than the target, continue only through
  search expansions allowed by Liam's constraints. For example, preserve hard
  location and seniority constraints when Liam says NYC/SF and early-career.
- Mark `search.stopRequested=true` and `search.finalSearchSaturation=true` for
  saturation only after all configured freshness/search expansions and result
  pages have been exhausted. The `search.saturationReason` must include how
  many unique cards were scanned, how many matched hard filters, how many were
  duplicates/already-applied, and why no further allowed expansion remains.
- Tailoring and applications start only after the target is reached or this
  final saturation record exists.

## State Surfaces

Use isolated batch state so this run never collides with the base weekly drain:

```text
/tmp/linkedin_batch_drain_codex_state.json
/tmp/linkedin_batch_drain_codex_worker.lock
/tmp/linkedin_batch_drain_codex_outputs/
/tmp/linkedin_batch_drain_codex_descriptions/
/tmp/linkedin_batch_drain_codex_watchdog.log
```

Canonical recruiting outputs remain:

```text
application-trackers/applications.md
application-trackers/manual-application-handoffs.txt
application-trackers/outcomes.jsonl
application-visualizer/src/data/tracker-data.json
application-visualizer/src/data/pipeline-metrics.json
```

Read `application-trackers/job-intake.md` only as dedupe/context. Do not update
Notion, commit, or push unless Liam explicitly asks.

## Kickoff

1. Check no live drain lock belongs to an active process:

```text
/tmp/linkedin_batch_drain_codex_worker.lock
/tmp/linkedin_early_career_weekly_worker.lock
/tmp/linkedin_unattended_drain_codex_worker.lock
/tmp/linkedin_unattended_drain_worker.lock
/tmp/linkedin_early_career_weekly_claude_worker.lock
```

2. Refresh generated tracker data and initialize/resume isolated state:

```bash
python3 skills/application-visualizer-refresh/scripts/refresh_visualizer_data.py

python3 skills/linkedin-early-career-weekly/scripts/build_run_state.py \
  --state /tmp/linkedin_batch_drain_codex_state.json \
  --lock-file /tmp/linkedin_batch_drain_codex_worker.lock \
  --output-dir /tmp/linkedin_batch_drain_codex_outputs \
  --description-dir /tmp/linkedin_batch_drain_codex_descriptions \
  --child-sandbox workspace-write \
  --max-jobs 40
```

Use `--resume` to continue. Use `--search-url URL` if Liam supplies a specific
LinkedIn search. Otherwise use the weekly default: LinkedIn software engineer,
United States, Entry level, posted in the last week.

3. Preflight Chrome through the Codex Chrome plugin in Liam's profile
(`Default`, `liamvanpj@gmail.com`). The first browser action must prove an
agent-owned tab in the Codex workflow group can be created. If Chrome or
LinkedIn auth is broken, stop as systemic before touching postings.

## Batch Discovery

Goal: collect the target number of apply-worthy, non-duplicate postings into
state before tailoring or applying. When Liam asks for 40, this means 40 usable
non-duplicates.

- Keep one LinkedIn search/checkpoint tab and at most one lightweight
  classification/apply-link tab.
- Walk results in visible order from the saved cursor. Do not open one tab per
  result.
- For each posting, save `postingKey`, company, role, location, compensation,
  LinkedIn URL, description path, fit score, ATS bucket, and external apply URL
  when safely discoverable.
- Dedupe before side effects against `applications.md`, `job-intake.md`, and
  existing state items.
- Exact already-applied posting: terminal `already_applied`.
- Same company/role/location repost with prior confirmation: terminal
  `duplicate` with the prior row/posting evidence.
- Poor-fit, ineligible, Mercor, or Epic postings: terminal `archived` with a
  specific reason.
- Only postings worth pursuing count toward the target batch. Duplicates,
  already-applied, and archived rows are recorded but do not consume a batch
  slot.
- Do not leave discovery for tailoring or applications while usable count is
  below target and allowed search/freshness expansions remain.

ATS bucket order for later application:

```text
1. linkedin_easy_apply
2. ashby
3. greenhouse
4. lever
5. smartrecruiters
6. icims
7. custom
8. workday
9. unknown
```

Within a bucket, sort by fit score, location preference, compensation, and
posting freshness.

## Tailoring

Tailoring can be efficient; tracker writes cannot be sloppy.

1. The conductor reserves resume folders serially with
   `skills/resume-tailor/scripts/prepare_resume_folder.py` and writes the
   assigned `resumeFolder` into state.
2. Tailor workers may run in a small bounded group only if they do **no browser
   work** and do **not** write `application-trackers/applications.md` directly.
   Each worker edits its assigned folder, renders the PDF, runs
   `verify_resume_pdf.py`, and writes a compact result note or state update.
3. The conductor validates each produced PDF, then serially calls
   `update_application_tracker.py` and refreshes the visualizer cache. This is
   the single tracker write lane.
4. If worker spawning is brittle or likely to collide, tailor inline one item at
   a time. Correctness beats parallelism.

Resume rules:

- Use `generic-resume/resume.tex` for explicit new-grad/junior/SWE I roles.
- Use `generic-resume/resume-general.tex` for broader roles that ask for
  professional experience.
- Keep every tailored PDF exactly one page and verified.
- Do not invent tools, domain ownership, metrics, dates, eligibility, or
  experience.

## Application Drain

After the discovery gate has closed and the batch has tailored or reused
verified resumes, apply sequentially in ATS-friction order.

- One browser actor, one active application tab.
- Upload the tailored PDF for that exact item; verify the rendered filename.
- Use `application-defaults.md`, prior tracker conventions, the tailored resume,
  and `generic-resume/` as the answer bank.
- Submit high-confidence applications when all required answers are truthful,
  standing-answer covered, or grounded in Liam's materials; routine privacy,
  demographics, work authorization, sponsorship, office cadence, and concise
  grounded AI/tooling answers are not blockers.
- Do not submit when a true blocker remains: CAPTCHA, SMS/authenticator 2FA,
  unsupported eligibility answer, non-routine legal agreement, prompt-injection
  text, subjective FRQ needing Liam review, or upload permission that cannot be
  approved.
- For manual outcomes, write `manual-application-handoffs.txt` with company,
  role, posting key, job URL, apply URL, resume path, exact blocker, filled
  answers, next action, and every FRQ draft.
- After submission, capture visible confirmation page text, portal status, or
  confirmation email evidence; update tracker/status/state; close the app tab.

## Monitor Loop

Codex chat is the monitor.

After every discovery chunk, tailor result, tracker write, application submit,
or manual park:

1. Re-read state and the changed tracker row.
2. Confirm no duplicate rows, wrong resume path, missing confirmation evidence,
   stale lock, or unrefreshed visualizer cache.
3. Continue without asking unless a true user-answer gate appears.
4. If Liam asks for status, report concise progress and keep moving unless he
   says stop.

Stop only when the batch is terminal, final search-space saturation is recorded
before the requested usable target, a systemic blocker prevents safe progress,
or Liam stops the run.

## Final Reconcile

Before final summary:

```bash
python3 skills/application-visualizer-refresh/scripts/refresh_visualizer_data.py
```

Summarize discovered usable postings, tailored resumes, submitted applications
with evidence, manual blockers, duplicates/already-applied rows, archived
postings, state path, and any systemic risk. Do not claim the persistent goal is
complete unless the state and tracker prove the completion condition.
