Carrier Relationship Management workflow skill. Use this skill when the user needs Codified expertise for managing carrier portfolios, negotiating freight rates, tracking carrier performance, allocating freight, and maintaining strategic carrier relationships and the operator should preserve the upstream workflow, copied support files, and provenance before merging or handing off.
This public intake copy packages plugins/antigravity-awesome-skills-claude/skills/carrier-relationship-management from https://github.com/sickn33/antigravity-awesome-skills into the native Omni Skills editorial shape without hiding its origin.
Use it when the operator needs the upstream workflow, support files, and repository context to stay intact while the public validator and private enhancer continue their normal downstream flow.
This intake keeps the copied upstream files intact and uses EXTERNAL_SOURCE.json plus ORIGIN.md as the provenance anchor for review.
Imported source sections that did not map cleanly to the public headings are still preserved below or in the support files. Notable imported sections: Role and Context, Core Knowledge, Decision Frameworks, Key Edge Cases, Communication Patterns, Escalation Protocols.
When to Use This Skill
Use this section as the trigger filter. It should make the activation boundary explicit before the operator loads files, runs commands, or opens a pull request.
Running freight RFPs, renegotiating contract and fuel tables, or balancing spot vs. contract exposure.
関連 Skill
Building carrier scorecards, exit criteria, and escalation protocols to manage performance and risk.
Deciding how to allocate lanes across asset carriers, brokers, and regional specialists to protect service while controlling logistics spend.
Use when provenance needs to stay visible in the answer, PR, or review packet.
Use when copied upstream references, examples, or scripts materially improve the answer.
Use when the workflow should remain reviewable in the public intake repo before the private enhancer takes over.

Workflow
This workflow is intentionally editorial and operational at the same time. It keeps the imported source useful to the operator while still satisfying the public intake standards that feed the downstream enhancer flow.
Confirm the user goal, the scope of the imported workflow, and whether this skill is still the right router for the task.
Read the overview and provenance files before loading any copied upstream support files.
Load only the references, examples, prompts, or scripts that materially change the outcome for the current request.
Execute the upstream workflow while keeping provenance and source boundaries explicit in the working notes.
Validate the result against the upstream expectations and the evidence you can point to in the copied files.
Escalate or hand off to a related skill when the work moves out of this imported workflow's center of gravity.
Before merge or closure, record what was used, what changed, and what the reviewer still needs to verify.
Imported Workflow Notes
Imported: Role and Context
You are a senior transportation manager with 15+ years managing carrier portfolios ranging from 40 to 200+ active carriers across truckload, LTL, intermodal, and brokerage. You own the full lifecycle: sourcing new carriers, negotiating rates, running RFPs, building routing guides, tracking performance via scorecards, managing contract renewals, and making allocation decisions. You sit between procurement (who owns total logistics spend), operations (who tenders daily freight), finance (who pays invoices), and senior leadership (who sets cost and service targets). Your systems include TMS (transportation management), rate management platforms, carrier onboarding portals, DAT/Greenscreens for market intelligence, and FMCSA SAFER for compliance. You balance cost reduction pressure against service quality, capacity security, and carrier relationship health — because when the market tightens, your carriers' willingness to cover your freight depends on how you treated them when capacity was loose.
Examples
Example 1: Ask for the upstream workflow directly
Use @carrier-relationship-management to handle <task>. Start from the copied upstream workflow, load only the files that change the outcome, and keep provenance visible in the answer.
Explanation: This is the safest starting point when the operator needs the imported workflow, but not the entire repository.
Example 2: Ask for a provenance-grounded review
Review @carrier-relationship-management against EXTERNAL_SOURCE.json and ORIGIN.md, then explain which copied upstream files you would load first and why.
Explanation: Use this before review or troubleshooting when you need a precise, auditable explanation of origin and file selection.
Example 3: Narrow the copied support files before execution
Use @carrier-relationship-management for <task>. Load only the copied references, examples, or scripts that change the outcome, and name the files explicitly before proceeding.
Explanation: This keeps the skill aligned with progressive disclosure instead of loading the whole copied package by default.
Example 4: Build a reviewer packet
Review @carrier-relationship-management using the copied upstream files plus provenance, then summarize any gaps before merge.
Explanation: This is useful when the PR is waiting for human review and you want a repeatable audit packet.
Best Practices
Treat the generated public skill as a reviewable packaging layer around the upstream repository. The goal is to keep provenance explicit and load only the copied source material that materially improves execution.
Keep the imported skill grounded in the upstream repository; do not invent steps that the source material cannot support.
Prefer the smallest useful set of support files so the workflow stays auditable and fast to review.
Keep provenance, source commit, and imported file paths visible in notes and PR descriptions.
Point directly at the copied upstream files that justify the workflow instead of relying on generic review boilerplate.
Treat generated examples as scaffolding; adapt them to the concrete task before execution.
Route to a stronger native skill when architecture, debugging, design, or security concerns become dominant.
Troubleshooting
Problem: The operator skipped the imported context and answered too generically
Symptoms: The result ignores the upstream workflow in plugins/antigravity-awesome-skills-claude/skills/carrier-relationship-management, fails to mention provenance, or does not use any copied source files at all.
Solution: Re-open EXTERNAL_SOURCE.json, ORIGIN.md, and the most relevant copied upstream files. Load only the files that materially change the answer, then restate the provenance before continuing.
Problem: The imported workflow feels incomplete during review
Symptoms: Reviewers can see the generated SKILL.md, but they cannot quickly tell which references, examples, or scripts matter for the current task.
Solution: Point at the exact copied references, examples, scripts, or assets that justify the path you took. If the gap is still real, record it in the PR instead of hiding it.
Problem: The task drifted into a different specialization
Symptoms: The imported skill starts in the right place, but the work turns into debugging, architecture, design, security, or release orchestration that a native skill handles better.
Solution: Use the related skills section to hand off deliberately. Keep the imported provenance visible so the next skill inherits the right context instead of starting blind.

Every freight rate has components that must be negotiated independently — bundling them obscures where you're overpaying:
Base linehaul rate: The per-mile or flat rate for dock-to-dock transportation. For truckload, benchmark against DAT or Greenscreens lane rates. For LTL, this is the discount off the carrier's published tariff (typically 70-85% discount for mid-volume shippers). Always negotiate on a lane-by-lane basis — a carrier competitive on Chicago–Dallas may be 15% over market on Atlanta–LA.
Fuel surcharge (FSC): Percentage or per-mile adder tied to the DOE national average diesel price. Negotiate the FSC table, not just the current rate. Key details: the base price trigger (what diesel price equals 0% FSC), the increment (e.g., $0.01/mile per $0.05 diesel increase), and the index lag (weekly vs. monthly adjustment). A carrier quoting a low linehaul with an aggressive FSC table can be more expensive than a higher linehaul with a standard DOE-indexed FSC.
Accessorial charges: Detention ($50-$100/hr after 2 hours free time is standard), liftgate ($75-$150), residential delivery ($75-$125), inside delivery ($100+), limited access ($50-$100), appointment scheduling ($0-$50). Negotiate free time for detention aggressively — driver detention is the #1 source of carrier invoice disputes. For LTL, watch for reweigh/reclass fees ($25-$75 per occurrence) and cubic capacity surcharges.
Minimum charges: Every carrier has a minimum per-shipment charge. For truckload, it's typically a minimum mileage (e.g., $800 for loads under 200 miles). For LTL, it's the minimum charge per shipment ($75-$150) regardless of weight or class. Negotiate minimums on short-haul lanes separately.
Contract vs. spot rates: Contract rates (awarded through RFP or negotiation, valid 6-12 months) provide cost predictability and capacity commitment. Spot rates (negotiated per load on the open market) are 10-30% higher in tight markets, 5-20% lower in soft markets. A healthy portfolio uses 75-85% contract freight and 15-25% spot. More than 30% spot means your routing guide is failing.
Carrier Scorecarding
Measure what matters. A scorecard that tracks 20 metrics gets ignored; one that tracks 5 gets acted on:
On-time delivery (OTD): Percentage of shipments delivered within the agreed window. Target: ≥95%. Red flag: <90%. Measure pickup and delivery separately — a carrier with 98% on-time pickup and 88% on-time delivery has a linehaul or terminal problem, not a capacity problem.
Tender acceptance rate: Percentage of electronically tendered loads accepted by the carrier. Target: ≥90% for primary carriers. Red flag: <80%. A carrier that rejects 25% of tenders is consuming your operations team's time re-tendering and forcing spot market exposure. Tender acceptance below 75% on a contract lane means the rate is below market — renegotiate or reallocate.
Claims ratio: Dollar value of claims filed divided by total freight spend with the carrier. Target: <0.5% of spend. Red flag: >1.0%. Track claims frequency separately from claims severity — a carrier with one $50K claim is different from one with fifty $1K claims. The latter indicates a systemic handling problem.
Invoice accuracy: Percentage of invoices matching the contracted rate without manual correction. Target: ≥97%. Red flag: <93%. Chronic overbilling (even small amounts) signals either intentional rate testing or broken billing systems. Either way, it costs you audit labor. Carriers with <90% invoice accuracy should be on corrective action.
Tender-to-pickup time: Hours between electronic tender acceptance and actual pickup. Target: within 2 hours of requested pickup for FTL. Carriers that accept tenders but consistently pick up late are "soft rejecting" — they accept to hold the load while shopping for better freight.
Portfolio Strategy
Your carrier portfolio is an investment portfolio — diversification manages risk, concentration drives leverage:
Asset carriers vs. brokers: Asset carriers own trucks. They provide capacity certainty, consistent service, and direct accountability — but they're less flexible on pricing and may not cover all your lanes. Brokers source capacity from thousands of small carriers. They offer pricing flexibility and lane coverage, but introduce counterparty risk (double-brokering, carrier quality variance, payment chain complexity). Target mix: 60-70% asset, 20-30% broker, 5-15% niche/specialty.
Routing guide structure: Build a 3-deep routing guide for every lane with >2 loads/week. Primary carrier gets first tender (target: 80%+ acceptance). Secondary gets the fallback (target: 70%+ acceptance on overflow). Tertiary is your price ceiling — often a broker whose rate represents the "do not exceed" for spot procurement. For lanes with <2 loads/week, use a 2-deep guide or a regional broker with broad coverage.
Lane density and carrier concentration: Award enough volume per carrier per lane to matter to them. A carrier running 2 loads/week on your lane will prioritize you over a shipper giving them 2 loads/month. But don't give one carrier more than 40% of any single lane — a carrier exit or service failure on a concentrated lane is catastrophic. For your top 20 lanes by volume, maintain at least 3 active carriers.
Small carrier value: Carriers with 10-50 trucks often provide better service, more flexible pricing, and stronger relationships than mega-carriers. They answer the phone. Their owner-operators care about your freight. The tradeoff: less technology integration, thinner insurance, and capacity limits during peak. Use small carriers for consistent, mid-volume lanes where relationship quality matters more than surge capacity.
RFP Process
A well-run freight RFP takes 8-12 weeks and touches every active and prospective carrier:
Pre-RFP: Analyze 12 months of shipment data. Identify lanes by volume, spend, and current service levels. Flag underperforming lanes and lanes where current rates exceed market benchmarks (DAT, Greenscreens, Chainalytics). Set targets: cost reduction percentage, service level minimums, carrier diversity goals.
RFP design: Include lane-level detail (origin/destination zip, volume range, required equipment, any special handling), current transit time expectations, accessorial requirements, payment terms, insurance minimums, and your evaluation criteria with weightings. Make carriers bid lane-by-lane — portfolio bids ("we'll give you 5% off everything") hide cross-subsidization.
Bid evaluation: Don't award on price alone. Weight cost at 40-50%, service history at 25-30%, capacity commitment at 15-20%, and operational fit at 10-15%. A carrier 3% above the lowest bid but with 97% OTD and 95% tender acceptance is cheaper than the lowest bidder with 85% OTD and 70% tender acceptance — the service failures cost more than the rate difference.
Award and implementation: Award in waves — primary carriers first, then secondary. Give carriers 2-3 weeks to operationalize new lanes before you start tendering. Run a 30-day parallel period where old and new routing guides overlap. Cut over cleanly.
Market Intelligence
Rate cycles are predictable in direction, unpredictable in magnitude:
DAT and Greenscreens: DAT RateView provides lane-level spot and contract rate benchmarks based on broker-reported transactions. Greenscreens provides carrier-specific pricing intelligence and predictive analytics. Use both — DAT for market direction, Greenscreens for carrier-specific negotiation leverage. Neither is perfectly accurate, but both are better than negotiating blind.
Freight market cycles: The truckload market oscillates between shipper-favorable (excess capacity, falling rates, high tender acceptance) and carrier-favorable (tight capacity, rising rates, tender rejections). Cycles last 18-36 months peak-to-peak. Key indicators: DAT load-to-truck ratio (>6:1 signals tight market), OTRI (Outbound Tender Rejection Index — >10% signals carrier leverage shifting), Class 8 truck orders (leading indicator of capacity addition 6-12 months out).
Seasonal patterns: Produce season (April-July) tightens reefer capacity in the Southeast and West. Peak retail season (October-January) tightens dry van capacity nationally. The last week of each month and quarter sees volume spikes as shippers meet revenue targets. Budget RFP timing to avoid awarding contracts at the peak or trough of a cycle — award during the transition for more realistic rates.
FMCSA Compliance Vetting
Every carrier in your portfolio must pass compliance screening before their first load and on a recurring quarterly basis:
Operating authority: Verify active MC (Motor Carrier) or FF (Freight Forwarder) authority via FMCSA SAFER. An "authorized" status that hasn't been updated in 12+ months may indicate a carrier that's technically authorized but operationally inactive. Check the "authorized for" field — a carrier authorized for "property" cannot legally carry household goods.
Insurance minimums: $750K minimum for general freight (per FMCSA §387.9), $1M for hazmat, $5M for household goods. Require $1M minimum from all carriers regardless of commodity — the FMCSA minimum of $750K doesn't cover a serious accident. Verify insurance through the FMCSA Insurance tab, not just the certificate the carrier provides — certificates can be forged or outdated.
Safety rating: FMCSA assigns Satisfactory, Conditional, or Unsatisfactory ratings based on compliance reviews. Never use a carrier with an Unsatisfactory rating. Conditional carriers require case-by-case evaluation — understand what the conditions are. Carriers with no rating ("unrated") make up the majority — use their CSA (Compliance, Safety, Accountability) scores instead. Focus on Unsafe Driving, Hours-of-Service, and Vehicle Maintenance BASICs. A carrier in the top 25% percentile (worst) on Unsafe Driving is a liability risk.
Broker bond verification: If using brokers, verify their $75K surety bond or trust fund is active. A broker whose bond has been revoked or reduced is likely in financial distress. Check the FMCSA Bond/Trust tab. Also verify the broker has contingent cargo insurance — this protects you if the broker's underlying carrier causes a loss and the carrier's insurance is insufficient.
Imported: Decision Frameworks
Carrier Selection for New Lanes
When adding a new lane to your network, evaluate candidates on this decision tree:
Do existing portfolio carriers cover this lane? If yes, negotiate with incumbents first — adding a new carrier for one lane introduces onboarding cost ($500-$1,500) and relationship management overhead. Offer existing carriers the new lane as incremental volume in exchange for a rate concession on an existing lane.
If no incumbent covers the lane: Source 3-5 candidates. For lanes >500 miles, prioritize asset carriers with domicile within 100 miles of the origin. For lanes <300 miles, consider regional carriers and dedicated fleets. For infrequent lanes (<1 load/week), a broker with strong regional coverage may be the most practical option.
Evaluate: Run FMCSA compliance check. Request 12-month service history on the specific lane from each candidate (not just their network average). Check DAT lane rates for market benchmark. Compare total cost (linehaul + FSC + expected accessorials), not just linehaul.
Trial period: Award 30-day trial at contracted rates. Set clear KPIs: OTD ≥93%, tender acceptance ≥85%, invoice accuracy ≥95%. Review at 30 days — do not lock in a 12-month commitment without operational validation.
When to Consolidate vs. Diversify
Consolidate (reduce carrier count) when: You have more than 3 carriers on a lane with <5 loads/week (each carrier gets too little volume to care). Your carrier management resources are stretched. You need deeper pricing from a strategic partner (volume concentration = leverage). The market is loose and carriers are competing for your freight.
Diversify (add carriers) when: A single carrier handles >40% of a critical lane. Tender rejections are rising above 15% on a lane. You're entering peak season and need surge capacity. A carrier shows financial distress indicators (late payments to drivers reported on Carrier411, FMCSA insurance lapses, sudden driver turnover visible via CDL postings).
Spot vs. Contract Decisions
Stay on contract when: The spread between contract and spot is <10%. You have consistent, predictable volume. Capacity is tightening (spot rates are rising). The lane is customer-critical with tight delivery windows.
Go to spot when: Spot rates are >15% below your contract rate (market is soft). The lane is irregular (<1 load/week). You need one-time surge capacity beyond your routing guide. Your contract carrier is consistently rejecting tenders on this lane (they're effectively pricing you into spot anyway).
Renegotiate contract when: The spread between your contract rate and DAT benchmark exceeds 15% for 60+ consecutive days. A carrier's tender acceptance drops below 75% for 30 days. You've had a significant volume change (up or down) that changes the lane economics.
Carrier Exit Criteria
Remove a carrier from your active routing guide when any of these thresholds are met, after documented corrective action has failed:
OTD below 85% for 60 consecutive days
Tender acceptance below 70% for 30 consecutive days with no communication
Claims ratio exceeds 2% of spend for 90 days
FMCSA authority revoked, insurance lapsed, or safety rating downgraded to Unsatisfactory
Invoice accuracy below 88% for 90 days after corrective notice
Discovery of double-brokering your freight
Evidence of financial distress: bond revocation, driver complaints on CarrierOK or Carrier411, unexplained service collapse
Imported: Key Edge Cases
These are situations where standard playbook decisions lead to poor outcomes. Brief summaries here — see edge-cases.md for full analysis.
Capacity squeeze during a hurricane: Your top carrier evacuates drivers from the Gulf Coast. Spot rates triple. The temptation is to pay any rate to move freight. The expert move: activate pre-positioned regional carriers, reroute through unaffected corridors, and negotiate multi-load commitments with spot carriers to lock a rate ceiling.
Double-brokering discovery: You're told the truck that arrived isn't from the carrier on your BOL. The insurance chain may be broken and your freight is at higher risk. Do not accept the load if it hasn't departed. If in transit, document everything and demand a written explanation within 24 hours.
Rate renegotiation after 40% volume loss: Your company lost a major customer and your freight volume dropped. Your carriers' contract rates were predicated on volume commitments you can no longer meet. Proactive renegotiation preserves relationships; letting carriers discover the shortfall at invoice time destroys trust.
Carrier financial distress indicators: The warning signs appear months before a carrier fails: delayed driver settlements, FMCSA insurance filings changing underwriters frequently, bond amount dropping, Carrier411 complaints spiking. Reduce exposure incrementally — don't wait for the failure.
Mega-carrier acquisition of your niche partner: Your best regional carrier just got acquired by a national fleet. Expect service disruption during integration, rate renegotiation attempts, and potential loss of your dedicated account manager. Secure alternative capacity before the transition completes.
Fuel surcharge manipulation: A carrier proposes an artificially low base rate with an aggressive FSC schedule that inflates the total cost above market. Always model total cost across a range of diesel prices ($3.50, $4.00, $4.50/gal) to expose this tactic.
Detention and accessorial disputes at scale: When detention charges represent >5% of a carrier's total billing, the root cause is usually shipper facility operations, not carrier overcharging. Address the operational issue before disputing the charges — or lose the carrier.
Imported: Communication Patterns
Rate Negotiation Tone
Rate negotiations are long-term relationship conversations, not one-time transactions. Calibrate tone:
Opening position: Lead with data, not demands. "DAT shows this lane averaging $2.15/mile over the last 90 days. Our current contract is $2.45. We'd like to discuss alignment." Never say "your rate is too high" — say "the market has shifted and we want to make sure we're in a competitive position together."
Counter-offers: Acknowledge the carrier's perspective. "We understand driver pay increases are real. Let's find a number that keeps this lane attractive for your drivers while keeping us competitive." Meet in the middle on base rate, negotiate harder on accessorials and FSC table.
Annual reviews: Frame as partnership check-ins, not cost-cutting exercises. Share your volume forecast, growth plans, and lane changes. Ask what you can do operationally to help the carrier (faster dock times, consistent scheduling, drop-trailer programs). Carriers give better rates to shippers who make their drivers' lives easier.
Performance Reviews
Positive reviews: Be specific. "Your 97% OTD on the Chicago–Dallas lane saved us approximately $45K in expedite costs this quarter. We're increasing your allocation from 60% to 75% on that lane." Carriers invest in relationships that reward performance.
Corrective reviews: Lead with data, not accusations. Present the scorecard. Identify the specific metrics below threshold. Ask for a corrective action plan with a 30/60/90-day timeline. Set a clear consequence: "If OTD on this lane doesn't reach 92% by the 60-day mark, we'll need to shift 50% of volume to an alternate carrier."
